The Second Machine Age is Erik Brynjolfsson and Andrew McAfee’s best-known work. The book explores the profound implications of rapid technological advances, particularly in digital technologies, for society, the economy, and the labour market. Published in 2014, the book delves into the transformative effects of what the authors term the ‘second machine age,’ a period marked by exponential growth in computing power, the ubiquity of digital networks, and the rise of artificial intelligence (AI) and robotics (page 9). Through a well-structured narrative, Brynjolfsson and McAfee argue that while these technological advancements hold immense potential for economic growth and societal progress, they also present significant challenges, particularly in terms of inequality and the displacement of labour (pages 11-12). In this review we examine some of the book’s arguments, structure, and contributions to the wider ongoing discourse on technology and society.
Brynjolfsson and McAfee’s central thesis is that we are entering a new phase of technological advancement that is fundamentally different from the first machine age, which was characterized by the mechanization of manual labour through the invention of the steam engine and other machinery during the Industrial Revolution. The second machine age, in contrast, is driven by digital technologies that augment and, in some cases, replace cognitive tasks traditionally performed by humans (page 9).
Brynjolfsson and McAfee’s book is structured in a logical and accessible manner, making complex ideas about technology and economics understandable to a broad audience. The book is divided into three main sections: the first outlines the characteristics of the second machine age (chapters 1-6), the second discusses its implications for the economy and labour market (chapters 7-11), and the third offers potential solutions to the challenges posed by these technological changes (chapters 12-15).
The authors identify three key characteristics of the second machine age: (1) exponential growth in computing power, (2) digitalization, which allows information to be replicated at virtually no cost, and (3) combinatorial innovation, where new technologies are built upon existing ones, leading to rapid and often unexpected advances (page 37). The authors argue that these characteristics are driving unprecedented changes in productivity, business models, and the global economy (chapters 1-6).
A significant portion of the book is dedicated to discussing the implications of the technological changes for the labour market (chapters 7-11). Brynjolfsson and McAfee argue that while technology has always created winners and losers, the pace and scale of change in the second machine age are likely to exacerbate inequality. They point to the phenomenon of ‘skill-biased technological change’, where technology disproportionately benefits those with higher levels of education and skills, leading to a widening gap between high-skilled and low-skilled workers (page 134). This dynamic is further amplified by the ‘superstar’ effect, where a small number of highly skilled individuals and companies capture a disproportionate share of the economic gains from new technologies (page 150)
The authors also explore the potential for technological unemployment, where advances in AI and robotics could lead to the displacement of a significant number of jobs, particularly in sectors such as manufacturing, transportation, and even certain white-collar professions (page 173). However, they are careful to distinguish between short-term disruptions and long-term trends, noting that while some jobs will undoubtedly be lost, new opportunities will also emerge, particularly in areas that require creativity, complex problem-solving, and interpersonal skills (page 191).
One of the strengths of the book is its use of empirical evidence and real-world examples, the authors drawing on a wide range of data, from economic statistics to case studies of companies and industries that have been transformed by digital technologies. This evidence-based approach lends credibility to their analysis and helps to ground their sometimes abstract ideas in concrete realities.
However, a critic might argue that the book’s optimistic tone about the potential of technology to drive progress and prosperity is not sufficiently tempered by a consideration of the potential risks and downsides. While the authors do acknowledge the challenges posed by technological change, particularly in terms of inequality and job displacement, they tend to focus more on the potential benefits of innovation and less on the potential for negative outcomes, such as social unrest, the erosion of privacy and the proliferation of misinformation (e.g. fake news) in an increasingly digital world.
Moreover, while Brynjolfsson and McAfee offer several policy recommendations to address the challenges of the second machine age, such as investing in education, reforming the tax system, and fostering innovation (Chapter 13), some of the discussion around proposals such as higher tax rates, universal basic income and negative income tax may seem overly idealistic and difficult to implement in practice (Chapter 14). Some readers may find the patches of real-world naiveté throughout the concluding chapters off-putting.
Despite all this, The Second Machine Age makes a worthwhile contribution to the wider discussion on technology, economics, and society. Brynjolfsson and McAfee’s nuanced discussion of the potential for both job displacement and job creation provides a comparatively thoughtful perspective that is often missing from more alarmist accounts of technological unemployment. Their focus on the importance of education and lifelong learning in preparing workers for the jobs of the future is commendable and a valuable contribution to the wider policy debate.
In concluding, The Second Machine Age is recommended to all readers who are interested in the profound technological changes reshaping our economy and society. While the book is not without its flaws, particularly in chapters where the tone may seem overly optimistic, it remains an important contribution to the discourse on technology and society. As we continue to grapple with the impacts of AI, robotics, and other advanced technologies, Brynjolfsson and McAfee provide a useful framework for understanding the challenges and opportunities that lie ahead.

Colin Mayer is a distinguished professor at the University of Oxford, former dean of the Said Business School and a Fellow of the British Academy . Throughout his career one of his fields of interests has been the business corporation and at present he is director of the Academy’s research programme into the Future of the Corporation.
However neither the title nor sub-title of the book do justice to its contents. The book is nothing if not ambitious. In examining the business corporation the claim is that “it will take you across history, around the world, through philosophy and biology to business, law and economics, and finance to arrive at an understanding of where we have gone wrong, why, how we can put it right and what specifically we need to do about it”.
The remarkable fact is that I believe he has achieved his aim. The book is wide in scope, has considerable depth and is not superficial. It is well written, interesting to read and draws on a lifetime of research into different aspects of the business organisation.
The book is first a sustained and vigorous attack on Milton Friedman’s claim that the sole social responsibility of business is to increase its profits, subject however to doing so in open and free competitive markets, without deception or fraud, while conforming to the basic rules of the society embodied in law and custom. For Mayer the public have lost trust in business precisely because business has followed Friedman’s advice and put the interests of shareholders above other stakeholders.
In its place he proposes a total reinvention of the corporation. Corporate law should be changed so that each company is required to state its ultimate purpose over and above profit, redefine the responsibilities of directors to deliver these new objectives, develop new measures by which they can be judged and introduce incentives to deliver them.
In exploring the purpose of business Mayer distinguishes between ‘making good’ (such as manufacturing cars, or electrical products) and ‘doing good’ (treating employees well, cleaning up the environment, enhancing the well-bring of communities). The latter has a social public-service element which goes beyond the private interests of the firm’s customers and investors, and even beyond section 172 of the 2006 UK companies Act, which already imposes duties on directors to take into account the interests of stakeholders other than shareholders. As examples of successful and enlightened corporations he mentions with approval “industrial foundations” companies such as Bertelsmann, Bosch, Carlsberg, Tata and John Lewis which are set up as foundations or trusts.
While I admire his ability to explore different dimensions of the business in one book, I have serious problems with his argument.
First, the pursuit of long term profitability is essential if a company wishes to prosper in the long term. Long term profit is a great discipline. This applies not just to publicly quoted companies; it applies equally to private companies, B-corps, partnerships, foundations and trusts. If companies of any kind make losses, capital will drain away and either they get taken over or go bust. This applies to all companies even those which are foundations and trusts. Not only that but long term profitability is a pre-condition of companies doing good: being able to reward employees well, help communities, develop new products and services for customers and invest to protect the natural environment. In this context it is important to distinguish between long term profitability and short term profitability.
The pursuit of short term profitability is bad business. Just recall the financial derivative products created by banks in the feverish boom years leading up to the 2008 crisis which ultimately led to some banks going bust and others being bailed out by governments. This was bad business. British Home Stores was a classic example of short term profit maximization with inadequate investment in the business itself or the pension fund. Again short termism leading to bad business.
Pursuing long term profitability is not just a matter of management getting numbers right. Before they can do that it requires them to set out a vision which makes the firm “a great place to work”, ensures customers recognize value for money in what they buy, becomes known as an ethical organization by the way they conduct business and admired by shareholders for earning a superior long term return to capital.
A second problem with Mayer’s proposals is the sheer complexity of managing the diverse and frequently opposing interests of stakeholders. It is logically impossible to maximize in more than one dimension. If managers have to manage the interests of all stakeholders they need to be able to make meaningful tradeoffs between competing interests. Profit or change in long-term market value is a way of keeping score in the game of business. Michael Jensen and others have shown that in the long term prospective profit maximization and shareholder maximization amount to the same thing. The use by management of a balance scorecard is no better as it ultimately gives no objective way in which to weigh all of the elements in the scorecard to arrive at a single figure.
A third problem with Mayer’s argument is accountability. “Accountability to everyone means accountability to no one”. The author’s proposal is a revolutionary re-definition of property rights within a modern corporation to make it “trustworthy” but to whom is the board of this new “trustworthy” corporation responsible? And what are the rights of ownership over the funds invested in the business? Already in the US the number of publicly traded companies quoted on exchanges has roughly halved over the past 25 years. One reason is the increasing cost of regulation: another is the availability of private equity finance. If Mayer’s proposals were ever to be implemented they would constitute a major disincentive for companies to raise capital through the public markets and only accelerate the decline in stock market listings.
In Mayer’s proposal shareholders would become providers of capital to business rather than owners of the business. The general public have never had a great trust in business which is why ever since the Industrial Revolution governments have stepped in to control business through laws passed by parliament, regulation, mutualisation, nationalization and state ownership. Mayer’s proposals will downgrade the existing well defined ownership rights which exist in publicly traded companies and replace them with a form of ‘social’ decision making in which the leadership of the company is answerable to trustees but shielded from competition in the market place through take over bids. A sure way to create inefficiency.
In this respect these proposals are a far cry from an exercise in academic research, more a political statement. Far from having no objection to the existence of ‘trustworthy’ corporations as one of many different forms of corporate ownership, I welcome them. In terms of corporate structures let a hundred flowers bloom. If the author was making a case for the idea of ‘Industrial corporation’, fine. However he is doing more than that. He is making the case for eroding private property rights and restricting what companies can do, which is as much a political statement as one based on objective analysis.

Economics has become less a series of doctrines than … an engine of analysis in which techniques, ranging from the theory of public goods and externalities, ideas about the role of property rights, negotiation, incentives, and mechanism design, are used together with ideas from other disciplines to work out possible solutions to very difficult problems.[1]
Roger Backhouse
Economics is the study of the allocation of scarce resources. This central focus, as much as anything else, makes it eminently suited to analyzing environmental problems. Let’s take a concrete example. The Columbia and the Snake Rivers drain much of the U.S. Pacific Northwest, providing water for drinking, irrigation, transportation, and electricity generation and supporting endangered salmon populations. All these activities – including salmon preservation – provide economic benefits to the extent that people value them.[2]
Nathaniel Keohane and Sheila Olmstead
While this publication is focused on considering the foundational economic issues connected with environmental protection, achieving a reasonable position requires some understanding of the pragmatic issues. For instance, the two related questions of into which issues the state should intervene to alter market outcomes and how it should do so depend in part on empirical questions about relevant alternatives. There are myriad existing regulatory mechanisms that attempt to improve outcomes. Do insights from economic analysis of their performance and the theories presented in the Chapters 1 and 2 present ideas about potential improvements?
Contemporary concerns are increasingly focused on climate change. This is because of the risks and costs associated with climate change and because of the success of environmental regulation, private actions and technological improvement in mitigating other environmental harms over the past decades. Despite the understandable focus on climate change, such comparatively mundane issues as air and water quality, habitat and species protection and fisheries management are still vital and register considerable interest.[3] In many cases climate change can be reduced with better management practices on these issues – a topic returned to in the short penultimate section on climate change.
Before getting into some specific environmental issues that show both the potential and limits of markets in assorted policy areas, it is necessary to provide some context for both the development of environmental policy and its economic analysis. The two quotes above are representative of the widely held view of economics as a policy science combining notions of efficiency, economic theory and rigorous empirical evaluation. While there is some question about the declining role of economists in policy discussions (such as climate policy in the Biden administration), economics manages to sit astride many topics and provide a framework for thinking about them.
Recent academic literature has attempted to reckon with the shift in policy in the last quarter of the twentieth century towards enabling markets and the rise of economic thinking over a broader period. Most of the work is on the United States and the United Kingdom; the focus in what follows will be on the former context. The term ‘neoliberalism’ is often but inconsistently used; the basic argument is that markets that were curtailed (or never existed) were freed (or created) by reforms beginning in the 1970s. To some degree these ideas were proposed by economists addressing the contemporary failures of their time, but they were also taken up by policy experts and political figures, on the left as well as the right. Nascent environmental policy is one example of a field where this was rampant, as Elizabeth Popp Berman details in her recent book, Thinking like an Economist.[4] This consensus broke down in the 2000s and the 2010s as the right shifted away from the more active policies involved in market-based regulation (while retaining a focus on deregulation), and the left became increasingly focused on distributional issues (what is called ‘environmental justice’) and green industrial strategy.[5]
Standard accounts rightly focus on the rise of the environmental movement in the middle decades of the twentieth century. It was then that major pieces of legislation were passed to regulate industrial polluters and clean up the environment. As Berman and others note, the language used in them – and the public debate around their passage – was markedly radical.
As one example, the Clean Water Act promised to end all water pollution. To show how far this was from the view of professional economists, Berman recounts:
Harvard economist Marc Roberts told the National Journal in 1972 that he was ‘a radical, a Democrat, and an ardent hater of Richard Nixon,’ yet continued, ‘There isn’t a single respectable economist in the country who would back the no-discharge goal adopted by the Senate [in the Clean Water Act]. It will waste billions of dollars for no useful social or environmental purpose.’[6]
These topics are popular both because of interest in the time period and a desire by interested parties to similarly reform policy. Many with environmental concerns hold that radical reform of state policy is needed to limit markets. This includes, at the extreme, those who think the consumption of resources and emissions of harmful substances generated by a wealthy society require degrowth. In her popular book Not the End of the World, Hannah Ritchie pushes back against the most pessimistic and doctrinaire claims of this kind with data on the progress made in the last decades.[7] Despite the pressing concerns of climate change, many of these ideas are not new, and earlier policy debates provide interesting context for contemporary ones, as does the performance of more idealistic regulation in the twentieth century.
Relevant for this chapter is how interventions for environmental purposes were conceptualised by both policymakers and economists. The through- line is that at least conceptually, reforms that enable markets to perform better (in efficiency terms) and in more dynamic ways, rather than direct command-and-control interventions, became more central to policy discussions over time (even if never that popular). Legislation passed at the time forbade some economic considerations but was rather based on concerns about health and a framework of creating rights to limit pollution irrespective of cost–benefit analysis. Initial proposals to introduce economic considerations were considered repulsive.
After a few decades the benefits of market reforms were more widely recognised, but for reasons connected to interest-group dynamics and politics generally, this conceptual victory has not led to the degree of reform many economists think desirable.[8] On the most important environmental issues, the last 15 years have witnessed a turn away from the standard economic advice of academic economists and towards a range of mandates, subsidies and other regulations. These are meant to enable an energy transition and combat climate change, while most economists support carbon pricing.
The 1960s was a decade of growing awareness of environmental issues, especially concerning air and water pollution and agrochemical toxicity. At the same time, the young field of environmental economics was developing as a specific focus among economists, separate from natural resources economics.[9]
Nathalie Berta
In 1960, a Gallup poll showed that just 1% of Americans saw ‘pollution/ecology’ as an important problem. By 1970, 25% did.[10]
Alec Stapp and Brian Potter
While earlier regulation attempted to address environmental harms (and legal judgements enshrined in common law created constraints on action), much of the existing legislation governing environmental harms dates only from the last five or six decades. Although environmental harms are frequently discussed in the language of standard economics, this was rarely the case at the time. Over the nineteenth and early-to-mid-twentieth centuries, environmental concerns were often couched in terms of either resource constraints or public health.
For issues like air or water pollution, their categorisation as either an environmental or a public health problem was unclear. In many cases pollution was the result of situations in which noxious output was paired with weather conditions that caused acute crises, such as London’s Great Smog of 1952. While earlier reforms attempted to clean the air, it was this acute crisis that led to the Clean Air Act of 1956, which represented a real political effort to limit pollution. The Great Stink a century earlier had resulted in direct government action to deal with sewage polluting the Thames. In both situations the science of the general health effects was initially contested but the acute public health crisis spurred lasting environmental benefits.
The scale of these issues was new because of the total numbers of people involved and the new forms of polluting technology. The smoke from isolated chimneys may cause little harm but in much of the developing world or in historic centres such as London, wood smoke alone (not to mention new pollutants) can create widespread health issues. Economic growth, population growth and the technological innovations that empowered both may have led to new harms, but the wealth generated by cities also enabled the capacity to pay for improvements.
In their textbook on environmental economics, Nathaniel Keohane and Sheila Olmstead emphasise the standard contemporary approach to considering policy: cost–benefit analysis. As they write: ‘The basic approach is simple enough: Measure the costs and benefits of each possible policy, including a policy of doing nothing at all, and then choose the policy that generates the maximum net benefit to society as a whole (that is, benefits minus costs).’[11] At a minimum, a policy must ‘pass’ cost–benefit analysis; that is, generate net benefits. Similar statements occur in a number of textbooks. While much of the popular discussion and political efforts are still driven by broader concerns, formal policy analysis focuses on cost–benefit analysis.This is relatively new: when the crises above emerged, there was little role for economic analysis in broader policymaking.
In the United States, legal cases and local ordinances provided some protections even before wider legislation. There was logic in the processes by which these rules were made and adjudicated but prior to the formalisation of cost–benefit analysis, much public debate took place without quantified estimates of the benefits of pollution abatement.
In the nineteenth century the growing ability of the state to raise revenue – and assumption that it should step in – led to increased state action, but again, much of this took place before the widespread emergence of public policy practices attempting to deliver net value. While some major projects, such as turnpikes, canals and railways, were largely private in the United Kingdom (though carried out via private acts of parliament), the rise of public infrastructure projects led to the formalisation of cost–benefit analysis of some kind.
The great nineteenth-century engineers and social reformers such as Jules Depuit in France and Edwin Chadwick in England were forerunners of thinking about economic incentives and processes and a form of cost- benefit analysis even began in eighteenth-century France.[12] Over the nineteenth and twentieth centuries, increasingly formal efforts sought to understand the nature of harms.[13]
As currently practised, however, formal analysis can be traced to the American federal infrastructure projects to control flooding as part of the Flood Control Act of 1936.[14] Over the twentieth century, analysis of this sort became formalised in government decision-making, beginning with flood control efforts and water projects in the American West. From there it developed both within government and think tanks such as RAND and Resources for the Future, and within federal agencies. As one historian writes: ‘It is not a story of academic research, but of political pressure and administrative conflict.’[15] By the late twentieth century, executive orders issued by presidents of both parties compelled regulatory agencies to do a form of cost–benefit analysis – regulatory impact analysis – on any rule changes.[16]
Yet within this approach there are key questions about how benefits can be measured – and therefore whether they count – and how to consider future benefits properly. Spencer Banzhaf’s recent history of the field shows how the broader accounting for benefits such as recreation and health transformed resource economics into environmental economics.
[E]conomists began to measure abstract indices like Gross Domestic Product and inflation as well as the benefits and costs of public investments. When they similarly turned to quantifying natural resources and the environment, economists realized that if they limited themselves to those resources traded in markets, which come with a readily observed market price, they would omit much of what society holds dear.[17]
Spencer Banzhaf
Prior to the rise of the contemporary environmental movement in the 1960s, much of what would now be considered environmental economics was focused on questions of natural resource economics. The questions emphasised were those of how to ensure resources weren’t wasted and new resources were developed.[18] Over the course of the twentieth century, new methods allowed quantification of some of ‘what society holds dear’ and so allowed policy analysis that included relevant benefits of environmental protection.
In his book Pricing the Priceless, Banzhaf draws on the standard contrast used to sort environmentalists: conservationists who emphasise the use of resources prudently and preservationists who emphasise the purer protection of nature as a thing set apart from human uses. The earlier twentieth-century economists didn’t think about the environment beyond the conservationist approach. This approach also fits historically into a Cold War continuation of the mobilisation of resources for armed conflict and post-war economic growth. The 1952 Paley Commission published a report entitled ‘Resources for Freedom’, which detailed the potential material risks of the next decades and emphasised ways to ensure material plenty.[19] The goal was to enable economic growth and war-making ability. Out of the commission the influential think tank Resources for the Future was founded. Over the course of the 1960s, attention shifted from the lack of natural resources towards questions of how to respond to the degradation of the environment.
Up to this point the mechanics of economic analysis were geared towards a particular conservationist approach almost by design. In the formalisation of cost–benefit analysis during the mid-twentieth century, projects and policies were evaluated by their productive economic impact, with little room in the analysis for the value consumers might place on environmental preservation. What economists call the ‘amenity value’ of things that individuals enjoy and might even be willing to pay for – but generally don’t directly – can be difficult to estimate in situations far removed from standard markets. Banzhaf argues that part of the revolution in the evaluation of these benefits – like using water to support endangered salmon in the Snake River in the quote at the start of this chapter – is tied to the reorientation of economics away from crude output and towards applied welfare. As economic analysis gets further away from working markets, welfare analysis becomes more difficult. Contemporary environmental economics seeks to find robust ways of estimating the value of environmental benefits. By doing so it can inform policymaking that relies on cost–benefit analysis.
Cost–benefit analysis of environmental harms seeks to reduce their varied and complicated forms to a financial figure. Distilling harms to a figure may be subject to dispute but allows comparisons across areas. It might be clear that it isn’t worth devoting resources – whether actively expending money or restricting potential uses – to garner benefits if the net benefits are small, but this can also be true if alternatives have much higher net benefits. While mostly focused on future policy, cost-benefit analysis also allows a look back at some of the regulation passed in the 1960s and 1970s. Pairing economic theory and applied economic thinking about environmental harms, it is possible to see some of the potential for market-based regulatory reforms. The history of cost-benefit analysis reveals the intellectual difficulties of rigorous applied economic thinking apart from the standard notion that politics is the constraint on good policy.
To make this difficulty more apparent, consider the management of a section of national forest in the American West. If the forestry officials are tasked with deciding between allowing the forest to be used by logging companies or continue being used for recreation, it is easy to assess a value for the flow of timber that can be harvested but more difficult – though far from impossible – to impute a value for the walks and picnics that people use the forest for. In part, because of this difference between the legibility of use value, government policy can discourage uses that contemporary environmentalists seek. While amenity values or use values can be estimated with contemporary methods, so-called ‘existence values’ or ‘passive use values’ are more difficult to estimate. These are the values that one places on, for example, glaciers in Switzerland or polar bears in the Arctic whether or not one observes (or directly uses) them.
For these, economists have developed ‘contingent valuation’ methods that allow some estimates for goods such as the preservation of Half Dome in the Yosemite National Park, biodiversity and the damages caused by widespread harms like the Exxon Valdez oil spill. Despite this, they continue to disagree about the estimates and whether they are valuable.[20] The standard view of economists is that survey methods to estimate preferences or willingness to pay are far inferior to market situations where individuals must confront trade-offs directly. The use of surveys to estimate value fails to yield robust results because revealed preferences in markets (i.e. people’s preferences as manifested by their behaviour) often vary considerably from self-reported preferences. The methods can be useful in the same way that market analysis is useful to companies prior to launch of a new product – something with notable failures for the same reason.[21]
Apart from the more controversial aspects of economic analysis of environmental degradation, it is worth stressing the related development in estimating the health benefits of reductions in pollution. Many of the public health benefits of improvement in, say, air and water pollution rely on the notion of the value of a ‘statistical life’ to quantify the value of the lives saved by the marginal reduction in, for instance, particulate matter smaller than 2.5 micrometres in diameter (μm 2.5). These tiny pollutants were not directly targeted by conventional attempts to reduce air pollution (including twentieth-century attempts to reduce things like sulphur dioxide). Contemporary estimates of the cost-benefit ratio of air pollution policies find that many of the benefits come from the health benefits associated with the fall in μm 2.5 pollution. These estimates required measurement of this pollution and the notion of the value of a statistical life to account for the benefits. Like contingent valuation, the value of statistical life is a construct with a long history and the subject of much debate, from both an ethical and applied economic perspective.[22]
Despite these difficulties, contemporary empirical research attempts to create precise estimates of the benefits of removing types of pollution via different mechanisms. This includes research on a wide range of matters, such as how much individuals are willing to pay to escape polluted neighbourhoods and how much air pollution harms health outcomes, to name but two. One standard finding is that the marginal abatement cost of pollution rises; that is, it becomes more costly to lower pollution by additional units.
By the late 1950s, both economists and policymakers had formed quite well developed and deeply entrenched visions of how pollution-control policy should be constructed. Unfortunately, these two visions were worlds apart.[23]
Tom Tietenberg
The US government sets abatements standards, enforces them, and sometimes even prescribes the technology to be used, without attempting to equate marginal costs across pollution sources or provide incentives for technical progress … The blame for this lies, in our judgement, partly with the Congress and executive agencies for ignoring economists, and partly with economists for recommending impractical policies and for not offering compromises.[24]
Anthony Fisher and Frederick Peterson
Despite the growth of environmental economics in the 1960s, little of this approach filtered into the contemporary American regulatory framework. This section outlines some of this framework’s key features and explains why economists have advanced policy proposals that seek to rationalise the existing environmental protections. These proposals include methods of regulation that seek to reduce pollution in line with the costs and benefits of abatement. Economists argue that better regulation can provide a given level of environmental protection at a lower cost. As Nathalie Berta shows, in making these claims about efficiency, the argument for expert policy slipped from ivory tower notions of an optimal amount of pollution to reducing pollution in a least-cost way.[25] Despite successful intellectual arguments, gaining activist support and some legislative successes, there are still large gains to be made from adopting more market-based mechanisms for environmental protection. The failure of more of these policies to be adopted (and in some cases existing wins were rolled back) is discussed later in this chapter.
One example of an area of environmental policy with the most substantial reforms inspired by economics is the regulation of air pollution in the United States, much of which is via provisions originally passed in the 1970 amendment of the Clean Air Act (CAA). As part of these provisions, the Environmental Protection Agency (EPA) sets emitter National Ambient Air Quality Standards, which are emissions limits for the six targeted pollutants. These standards are set without consideration of abatement costs – though regulatory attempts to achieve these standards do consider costs. The
CAA also requires a State Implementation Plan for how states will reach those limits. Areas out of compliance generate additional regulations on existing and new polluters. Additionally, the act sets out that new industrial polluters are to be regulated according to technological standards via New Source Performance Standards issued by the EPA. These vary based on a number of factors, often but not always including cost. The 1970 amendment substantially altered the original 1963 legislation, and two major amendments took place in 1977 and 1990 (discussed below). The legislation also allows the discretion of the executive branch; since the 1980s executive orders have been subject to cost-benefit/regulatory impact analysis.
In the years since the passage of the 1970 CAA, the major pollutants have fallen in response, though causal estimates are difficult to generate. There is a consensus in the literature that the CAA reduced pollution relative to the baseline and passes retrospective cost–benefit analysis.[26] Much of the benefit derives from the health impacts of the reduction of the major pollutants. Despite the scale of the legislation and the active work of researchers, many of the aspects one would need in order to set optimal policy remain unknown. There is no reason to think the reductions were achieved at least cost, and there are clear examples of unintended consequences.
One example is from the 1977 amendment to the CAA that prescribed the technical requirements of new coal-based power plants to reduce emissions of noxious sulphur dioxide (SO2). This technical standard was in the interest of coal producers in the Eastern United States because they sold higher-sulphur coal, something not lost on them or their political allies.[27] Once industrial users met the standard by implementing the technology, they were free to pollute and therefore they were also free to minimise costs by using the cheaper, easier-to-transport eastern coal rather than the cleaner coal from the Western United States. The technical standard had no mechanism to govern the amount of SO2 generated. The absurdity of the rule is that even were a power plant able to achieve a reduction in the pollutant without the costly technology by using coal with less sulphur, the regulatory standard would rule them out of compliance because they didn’t install the technology. Furthermore, the height of the smokestacks increased in response to efforts that sought to improve local air quality. By increasing the height, industrial polluters were able to pollute in a way that generated acid rain miles away – including over international borders – as the pollutants fell back to earth. This is an example of public choice problems– dirty coal producers concentrated in politically important districts – combining with imprecise rules to result not just in a failure to solve existing environmental problems but also the generation of a new one in the form of acid rain. These failures of the conventional regulatory approach and the constrained fiscal space provided the political interest for an experiment in market-based reforms in 1990, explored under ‘Creating Markets in Practice’ below, preceded by the following discussion of the theoretical framework.
By the middle of the 1960s the waning focus on the importance of material resource constraints was being replaced by concern for the ill effects associated with material prosperity.[28] Economists at Resources for the Future and other organisations spearheaded efforts to address environmental degradation via more efficient approaches. Despite the association with Arthur Pigou, contemporary ideas about taxing pollution stem from Allen Kneese. Together with economists thinking about trading mechanisms, it was Kneese who sought least-cost ways to address environmental concerns. Achieving a given target at least cost was both more attainable than the idealised approach of taxing pollution at its marginal social cost and more efficient than heavy-handed regulation.
Kneese’s foundational work focused on the governance of water resources.[29] Here, a number of related questions arise about alternative uses and the impact of one use on another. In response to the complicated, interrelated system, Kneese argued – in line with Pigou – that a theoretically optimal solution would be ‘a system of spatially differentiated effluent fees, ideally set at the marginal damages of emissions’.[30] However, because this was untenable (at least for the time being), Kneese proposed a system whereby emitters were charged when water quality dropped below a regulatory standard (or emissions went above a certain level). Regulators could adapt prices in response to the observed reduction. But the logic of the tax would mean that emissions were reduced by those who could do so at a cost cheaper than the tax, while those for whom the tax was cheaper would continue polluting. As Banzhaf mentions in his treatment, ‘[Kneese] stressed the fact that with effluent charges, the market – not a planner – would find the way to reduced pollution.’[31]
Considering the difficulty – and cost – of estimating the benefits of abatement, Kneese showed that taxes could be applied over a politically determined level of emissions, with the benefit that the market would choose how to achieve it.[32] This represented the beginning of contemporary attempts to achieve environmental goals at least cost, rather than seeking an impractical optimal policy that achieves the economically ideal amount of reduction at least cost. While the level selected by the political process may be too high or too low (as compared to the textbook ideal), the process for achieving the level ensures that it does so in a way that doesn’t suffer from the waste of command-and-control regulations. This standard-and-tax approach was further developed by William Baumol and Wallace Oates.[33]
Such an aspect of the appeal of market-based regulations brings up a fundamental question about the nature and role of markets. While recent decades have seen an expanded understanding of what constitutes a marketplace, including domains previously considered outside market frameworks, this broader perspective has introduced important tensions in how we approach environmental challenges. Most advocates of market mechanisms take a moderate position, acknowledging that pure laissez-faire approaches may be insufficient for addressing contemporary environmental problems, particularly the most pressing issues of the twenty-first century. This moderation reflects a nuanced understanding that while conventional markets may emerge naturally, environmental issues often require some form of intervention to address market failures.
The key insight is that environmental policies, though preferable to no regulation at all, frequently achieve their pollution reduction goals at unnecessarily high costs. This has led to the development of market- based regulations that attempt to mimic the efficiency benefits of market mechanisms while addressing the inherent challenges of environmental management. More committed free-market environmentalists, while potentially sceptical of extensive regulation, often acknowledge that such market-based reforms represent an improvement over traditional command-and-control approaches.
Apart from the standard-and-tax approach, regulators can also generate trading by explicitly creating property rights to emit via a cap-and-trade programme.[34] Here a regulator puts an upper limit (‘cap’) on something like units of pollution and allows those affected by the cap to buy and sell (‘trade’) their rights or permits among themselves. Many ascribe the direction of travel in economic thinking about environmental regulation involving tradeable rights to Ronald Coase and set market-based regulations against both idealised Pigouvian taxes and command-and-control approaches. As a historical claim this argument runs into difficulties, but there is much similarity between Coase’s thinking and cap-and-trade approaches.
Coase’s foundational ideas about market mechanisms for managing spillover effects emerged not from his famous 1960 paper discussed in Chapter 1 but from his earlier work on radio spectrum allocation,[35] which bears closer resemblance to pollution trading markets. In examining the Federal Communications Commission’s (FCC) approach to managing broadcast frequencies, Coase challenged the conventional wisdom that government regulation through licensing was the only solution to managing signal interference between broadcasters. The existing system in the United States had evolved into a complex regulatory regime whereby the FCC awarded narrow frequency bands with wide buffer zones, allocating these valuable licences through arbitrary ‘beauty contests’ that consumed substantial resources from potential broadcasters.
Coase argued that the radio spectrum was not fundamentally different from other resources that markets successfully managed. He proposed replacing the discretionary licensing system with an auction mechanism in which the government would define clear usage rights and sell them to the highest bidders, allowing subsequent free trading of these rights. This proposal faced fierce resistance from both politicians and FCC regulators,but when spectrum auctions were implemented in the 1990s they not only generated significant revenue for the federal government but facilitated the rapid development of mobile phone technology, validating Coase’s insight that market mechanisms could efficiently allocate even complex resources with spillover effects (the interference). Taken together, estimates of these efficiency improvements are around $17 billion dollars.[36]
Shortly after Kneese’s first developments of his effluence fee scheme (and nearly ten years after Coase’s FCC paper), two economists – Thomas Crocker and John Dales – are generally credited with proposed emissions permits schemes whereby regulators would set a cap of total emissions and divide this cap into permits to pollute.[37] Thus, instead of setting (and re-setting) a tax in order to achieve an emissions target (as companies could choose to pay the tax instead of reducing emissions to the level desired), emissions would be reduced by way of a cap-and-trade system. As in Coase’s article on tradeable spectrum rights, Dales considers the foundational issues before arguing for a property rights scheme:
Economists tend to assume implicitly that it is impossible to own water and therefore seek to devise artificial price systems that are identical to what prices ‘would be’ if ownership were possible. The alternative strategy is to devise an ownership system and then let a price system develop. The purpose of this article is to suggest that there are very considerable advantages to attacking our water problems by means of a system of property rights.[38]
Cap-and-trade combines some of the benefits of the purer taxation approach with the political – if not necessarily welfare-enhancing – benefits of the command-and-control approach. Without examining any issue in detail, it is possible to think about some benefits that – an economist would point out – flow from this system as opposed to more standard command- and-control approaches. For one thing, the system is beneficial when the abatement costs that firms face vary. As shown in Chapter 1, this is one of the benefits of the tax approach as well. In the case of cap-and-trade, firms that engage in production that results in less pollution on the margin will be encouraged to continue producing – and perhaps even expand production – while those that engage in production that results in more pollution on the margin will be encouraged to produce less. It also maintains the incentives for firms to invest in known means of reducing pollution, as well as in research and development into new methods.
For policymakers, a benefit of the cap-and-trade mechanism is that it ensures a certain level of emissions can be achieved. In practice, when for scientific or political reasons achieving the target is of utmost importance, this is a drawback of the tax strategy because policymakers may choose to set the tax at a certain level hoping to achieve a certain result, yet find that the tax is too low to achieve it. This benefit of the cap-and-trade system is even more evident over time, as the permits market adapts to
changing circumstances without explicitly changing the rate of tax. In theory, politicians could vary tax rates in pursuit of efficiency, but this runs into obvious political difficulties. The system also spurs innovation as companies look for new ways to reduce emissions when permits become valuable.
While conceptually clear, there are of course specific questions about implementation. The level of geography (whether local, regional, or national) and timespan for permits matter, both in theory and in practice. Additionally, theory suggests that assigning permits via auction is the most efficient outcome, while the political constraints of the situation generally result in their being allocated to existing polluters. Caps can also be designed to become progressively tighter as permits are retired. As the cap tightens over time, permit prices tend to rise, creating stronger incentives for developing – and adopting – cleaner technologies.
In the most important contemporary issue, the distinction between tradeable property rights and taxation is perhaps the least emphasised, instead falling under the combined concept of ‘carbon pricing’. This can occur via a cap on emissions and a resulting price being generated via market trading, or via a tax. As discussed below, the benefits of each are still debated,[39] but first, it is worth looking at how this theoretical development was adopted by regulators.
The first generation of American environmental regulations did not take advantage of the benefits of market-based mechanisms. Some later reforms have introduced them, in part because of the theoretical argument being won but also as a result of increased political interest in market-based mechanisms. Some of this interest was due to the increasingly fractious politics surrounding tightening environmental reforms in the slower-growth 1970s and the general political environment, but also to the success of incremental reforms at meeting targets that would otherwise not have been politically achievable. This section considers examples from the development of regulations emanating from the CAA,[40] most notably the SO2 trading scheme.
A consensus around the type of least-cost mechanisms discussed above formed in academic economics, but in some cases the market-based mechanisms were, surprisingly, proposed by political and regulatory figures in the early 1970s. For instance, the Nixon administration had sought to regulate SO2 with them from the outset. In other cases, as with an early attempt to allow emissions trading in California via state regulators, political pressure shot it down, or the ethical arguments over the right to pollute and the proper role of cost-benefit analysis in environmental/health regulation stymied early efforts. But Charles Halvorsen showed how regulators themselves increasingly turned towards market-based mechanisms.[41] Some of the successful programmes included so-called ‘bubbles’, which allowed polluters to aggregate their emissions between the plants that they owned, and offsets, which allowed new plants – which would have otherwise been banned – to gain approval by reducing existing emissions at a ratio of more than 1:1. Despite this opening-up to market mechanisms, regulators required approval for each scheme and otherwise limited the extent of adoption.
The development of market-based regulatory environmental mechanisms by the EPA and policymakers in the late twentieth and early twenty-first centuries represented shifts in regulatory strategy. After a few smaller-scale experiments (including removing lead from gasoline), the most notable example is the SO2 emissions market enabled by the 1990 amendments to the CAA.[42] A key milestone was Project 88, sponsored by Democratic Senator Timothy Wirth and Republican Senator John Heinz, and directed by the economist Robert Stavins, which proposed using market principles to address environmental challenges.[43] The project report covered a number of environmental issues, including ones that hadn’t been directly targeted by regulation. In line with the move from determination of optimality to achieving goals by efficient mechanisms, the report states:
This study is not about setting environmental goals by the use of economic criteria. It does not recommend the use of benefit-cost analysis, or setting dollar values on environmental amenities or human health. Indeed, for the most part, the report eschews judgement on goals and standards. It does not suggest how much air pollution is acceptable, how many acres of wilderness are needed, or how to balance the need for controlling emissions of toxic chemicals with the costs of such controls. These are important – even crucial – questions. But there is a need to set aside ongoing debates over specific environmental standards, in order to carry out a separate examination of effective mechanisms for environmental protection.[44]
One of its case studies set out a proposal that eventually became the SO2 emissions trading programme in the 1990 CAA amendments, creating a cap-and-trade system for reducing the emissions that were causing acid rain. Its adoption was influenced by the Environmental Defense Fund (EDF) and renewed interest in environmental outcomes among Republicans after a mainly deregulatory focus at the EPA under President Reagan. This approach, championed by EDF and economists-cum-policy entrepreneurs like Stavins, allowed companies to buy and sell pollution credits, providing financial incentives for more efficient emissions reduction. The programme has been studied by many scholars, and in line with theory, research has found that it achieved reductions at costs between 15% and 90% lower than command-and-control regulations. Furthermore, the incentive to achieve reductions at a lower cost spurred innovation in burning processes and technology.[45] Subsequent market-based mechanisms for carbon dioxide and other pollutants have built on this framework, California’s carbon cap- and-trade programme serving as a prominent example in the mid-2000s.
While market-based regulations, such as those creating trading programmes, offer efficiency gains over standard command-and-control, it should be remembered that political forces impact the nature, timing and existence of market-based regulations, which is relevant both for questions of assessment and for the viability of future schemes. For instance, one point of contention in the SO2 trading scheme was that EPA administrators – and environmental activists – insisted on classifying the tradeable rights as allowances and not a form of property subject to protections against later changes.[46] This type of insistence and the resulting uncertainty about the permanence of trading schemes has scuppered other markets.
Despite the importance of comparative institutional analysis in determining the relative performance of alternative regimes, Gary Libecap argues that: ‘In general, transaction costs are not examined in depth in the environmental economics literature. This is particularly the case for the costs of political bargaining and lobbying that arise from implementing and administering government regulation and tax policies, although these costs have received somewhat more attention with cap-and-trade regimes.’[47] Yet even here it is important to be clear that the caps are the result of a political process. Insofar as the cap is informed by economic analysis, it is often fairly casual. As Stavins writes of the SO2 cap:
When the policy was enacted, no credible estimates of economic benefits of alternative target levels were available … Instead, the target was selected based on what was believed to be the ‘elbow’ of the abatement cost curve – that is, a level of abatement that was possible at relatively low costs, and above which the marginal costs of reducing emissions would climb dramatically.[48]
While economics can inform and improve policy, both electoral and bureaucratic politics shape even market-based policy. Government policy and taxpayer money should be devoted to the environmental protection that is most needed. In some cases, privatisation can generate revenue and improve outcomes by empowering market mechanisms. In many of the most difficult cases, such as air pollution caused by disparate sources, the issues are likely to result in government policy improving outcomes when compared to a laissez-faire approach. Status quo (command-and-control) regulation can benefit from basic economic thinking about the issues, and as seen in the reforms presented in this section the stars can align and improve policy. While this section has focused on air pollution, the logic of other regulatory systems is discussed in the next.
While regulation cannot be analysed in detail here, it is worth offering a few examples of the status quo regulatory attempts to limit environmental harm across different policy areas, along with realistic market-based proposals to improve them. The examples are presented by topic area but underlying this they are broadly organised by order of increasing difficulty. Later proposals move towards increasingly involved regulations to create markets – as has been attempted in efforts to limit air pollution – rather than expecting them to emerge. Environmental problems represent a spectrum of issues that vary in their amenability to market solutions.
When thinking about how to address environmental issues, there are various factors to consider, from the origins of harms to their effects and reach, and how policies relate to each. For the most difficult issues, such as climate-change policy, there are myriad levers and policies that influence both the generation of the environmental harm and the scale of damage caused by it. For some pollutants the threshold for harm is clear – amounts below it cause little harm and marginal harm increases above it. In some cases, such as climate change, the emissions have the same impact on the issue at hand wherever they are released in the world. But even for regulatory schemes targeting climate emissions, the underlying behaviour generating greenhouse gases also generates local emissions. Policies can be adjusted to account for these concerns, including those of environmental justice activists and organisers.[49]
It is perhaps easiest to think about this variation in amenability to market mechanisms in terms of the transaction costs, which are to an extent determined by the nature of the resources involved in the environmental problem at hand. At one end are resources with clearly definable property rights and relatively localised impacts, such as timber production or riparian fishing, where private ownership can effectively align incentives for sustainable management. Moving along the spectrum there are resources with increasing complexity in terms of spillover effects and measurement challenges, such as watershed management and open-water fisheries, where hybrid approaches combining market mechanisms with regulatory oversight have merits. And at the extreme end lie greenhouse gases that threaten climate stability and atmospheric quality, where the global nature of impacts, scientific uncertainty and inability to exclude users make purer market solutions impractical and state involvement all but necessary.
This framework helps policymakers identify where market-based tools might be sufficient on their own, where they need to be supplemented with other approaches and where alternative policy instruments might be more appropriate. The basic point throughout the following examples is that state solutions to environmental problems are often suboptimal and can be improved with economic thinking.
[T]ransaction costs … tend to be at their lowest in the case of land-based issues… Other stationary resources, such as oyster beds and water-based assets such as rivers and inshore fisheries that are excludable with existing technology also exhibit relatively lower bargaining and enforcement costs. Although in many cases such assets are amenable to private ownership of one form or another, the political/ideological framework often prevents the development of environmental markets even where they have considerable potential to improve resource allocation.[50]

Over the past decades, private lands have increasingly been brought into conservation. In the United States these include lands purchased by such trusts as The Nature Conservancy and many smaller organisations. Apart from explicitly charitable organisations, land is being conserved by private owners such as Ted Turner, among others. More complex contracting mechanisms allow landowners and environmentalists to interact in mutually beneficial ways. Perhaps chief among these are conservation easements, which have grown to cover millions of acres.[51] These allow land to be held privately with restrictions that prevent certain environmentally harmful uses, such as, most obviously, building on them but also farming that generates nutrient pollution, or harvesting trees. Parties customise the easements depending on the nature of their goals, but it is difficult to remove easements once they are placed on the property. These efforts show the capacity of private individuals to conserve land with taxpayer support via tax credits introduced by governments.[52]
But for reasons discussed earlier, the public-interest argument for leasing public lands was to encourage their cultivation. There are binding rules either to use the land or forfeit the right to the lease. Conservation activities are not classified as uses of the land so in practice, this has led to a situation in which public lands can’t be leased by those wishing to use the land for conservation, while private lands can be. The rules thwart efforts to lease the land directly and to enter into agreements with those who have leased government land for myriad activities ranging from cattle ranching to logging. This is of importance in much of the American West, where a large share of land is held by different federal agencies.
In discussing the recent reforms to the Bureau of Land Management (BLM) rules to allow new leases to be issued for conservation, Shawn Regan writes of the general principle:
A better, market-based approach would allow competing groups to negotiate with or bid against each other to determine which use has more value to prospective leaseholders – mining, for instance, or restoration. This would streamline the lengthy and contentious battles that often pit extractive industries against conservation interests over certain tracts of land.[53]
The 2024 reforms still make it difficult for conservation groups to bargain with existing leaseholders in extractive industries, and while the BLM manages about a tenth of the land in the United States, the National Forest Service and other agencies still manage large swathes that are unaffected. Reforms and targeted incentives would allow markets to conserve land efficiently.
Some of these same features apply to waterway management, particularly in places like the Western United States where natural rainfall is low. Large populations rely on water collected in major reservoirs, transported long distances and taken from aquifers. This is also true of irrigation for agricultural users. There is a large degree of government involvement both within the legal system of water rights – where there is wide variation – and in public utilities.
Somewhere like the Colorado River basin involves millions of users over numerous jurisdictions. Water is used for recreation, direct consumption, agricultural production and the generation of power, among other things. Chief among these, of course, is the water left within the system for fish to live in, large mammals to drink and natural vegetation to grow. These so- called ‘instream’ uses have received increased attention in recent years as drought has caused levels to fall.
Two striking features of water governance are, first, how difficult it is to exchange property rights, and second, how little price mechanisms are used to ration water. In parts of the American West, water concerns prevent valuable residential development despite the marginal economic value of the water to the new residents being high enough to compensate existing users who value the marginal unit of water less. (The uses of water they would reduce first if the price were higher would likely include things like reducing the size of the front lawn). The nature of the system of allocation often means existing users have little interest in stewarding the water they use because they face lower – or in some systems zero – marginal cost; in the extreme, use-it-or-lose-it allocations encourage waste. More generally, without metering and charging a cost per unit, there is little reason to reduce use. This is true of many agricultural users but also residential users in water districts with earlier rights to water. For illustration, Sheila Olmstead cites research from 2008 showing that ‘farmers in Arizona’s Pima County pay $27 per acre-foot, and water customers in the nearby city of Tucson pay $479–$3267 per acre foot.’[54] For some farmers, their most valuable asset may be their water rights. While some trades do take place, the regulatory complexity in sales or leases adds unnecessary complexity, raising transaction costs.
More than just charging different rates to different users, when faced with drought, water authorities routinely engage in public appeals to conserve water and, for example, turn off fountains in parks and museums. In California, citizens are encouraged to report neighbours who let water run off their lawns. Yet as Olmstead cites, these types of rationing rules are costly.[55] Technology standards like low-flow toilets or mandating certain types of appliances are also less efficient than simply raising prices. They also suffer from a rebound effect whereby consumers use more as efficiency improves – which is also true of insulation and heating improvements.
Economists find this type of regulation – as opposed to charging higher marginal rates above a certain threshold of use or rebating some basic level of use for low-income users – rather bizarre. Regulation can be warranted in places where the market is expected to face difficulties, but in many cases the regulation is what limits the capacity of markets to do social good.
The differential treatment of agricultural users is not just a feature of the water prices they face. Increasingly stringent regulation on American waterways has meant there are few point sources of pollution left; that is, most pollution results not from drainage pipes from industrial users but from accumulated runoff from fields and roads that drains into watersheds.[56] The Clean Water Act leaves much of this pollution to the states, and while some have made efforts to reduce it, agricultural interests and the difficulty of regulating such disparate pollution have resulted in relatively little progress. Increasingly large sums of money are spent to further reduce some sources of water pollution while little is done to reduce pollution in cheaper ways because the two sources of water pollution are regulated differently. Recent judicial rulings in Europe have resulted in cost- prohibitive restrictions on the nutrient runoff from new polluters such as housing developments.[57] In the United Kingdom, potential exchanges were allowed but faced high transaction costs. Recently proposed reforms seek to allow new polluters to pay into a fund that the government uses to abate pollution in lower-cost ways.[58]
Instream uses of water rights have faced a similar challenge to the example above, of land used for conservation not falling into the standard of use set out by legal rules or regulations. Water-use rights in much of the American West depend on so-called ‘use-it-or-lose-it’ rules. Absent changes in the law, water rights purchased by conservation groups to leave water in rivers and streams for riparian habitats – rather than remove it for use on fields or human consumption – wouldn’t be classified as a use and would therefore risk being lost. This has occurred in some states including notably the Oregon Water Trust (later the Freshwater Trust) which has traded with local users to acquire water rights that allow them to improve and maintain salmon habitats among other things.[59]
Air pollution was discussed above, but a recent experiment in India – the first to apply industrial emissions trading to μm 2.5 particulate matter regulation – is worth mentioning here.[60] As additional research shows, the harms of this type of pollution, and many countries seek to improve air quality with the least economic harm, this experiment may prove influential. The researchers found that the cost of achieving the existing target for pollution via a cap-and-trade mechanism was 11% lower than the pre- existing plant-level controls. As it happened, the targets could be more aggressively set because polluters could achieve reductions at a lower cost. This made it politically viable to maintain lower targets. Compared to the control groups, the treatment group of plants regulated by the cap-and- trade system produced between 20% and 30% less pollution in practice because caps could be tightened. While theoretically targets could be set too low and reduce pollution below an optimal level, in this instance the cost–benefit analysis suggests that the benefits were around 25 times higher than the costs. One important feature of this experiment is that it also reduced the administrative cost of lowering pollution – something particularly valuable in contexts where past efforts to enforce regulation have failed.
Chapter 2 introduced the economic root of the environmental problem with fisheries: the high transaction costs involved in establishing property rights create an incentive to catch more fish than is sustainable. This is a classic collective action problem because any one person who seeks to limit overfishing has no means to stop others from acting in their own interests. Despite government policies to limit overfishing, poorly designed policies mean that resources are wasted as fishing enterprises invest in faster and bigger boats, for example, to maximise the catch during the short fishing seasons mandated by regulators. Ecologically determined seasons don’t solve the fundamental economic problem of fisheries management, with the result that seasons become ever shorter while fish stocks continue to be at risk.
While Elinor Ostrom showed that self-governance mechanisms can emerge in some settings, in higher transaction-cost settings, market-based regulations in fisheries have proved successful.[61] These typically operate through systems such as Individual Transferable Quotas, where fishers receive tradeable rights to harvest specific amounts of fish based on the sustainable yield (or the shareholders in a collectively owned fishery can themselves set the allowed catch).
This creates a property rights system that incentivises long-term sustainability, as quota holders have a vested interest in maintaining healthy fish populations to preserve the value of their quotas. The transferability allows more efficient operators to acquire additional quotas, potentially leading to better resource management while reducing overcapacity in fishing fleets. Competition occurs in the marketplace for the property rights rather than in open waters. Despite emerging in the literature in the 1970s, political challenges have slowed take-up of property rights systems in fisheries management, though there has been notable progress.[62]
Fish with widespread migration patterns, such as Atlantic tuna, provide a uniquely challenging fisheries management issue.[63] While domestic fisheries management similarly grapples with monitoring, enforcement and biological sustainability, international management must address these concerns across multiple jurisdictions, political systems and economic contexts. The added layers of international law, varying enforcement capabilities and cross-border transaction costs create a level of complexity that makes even successful domestic fishery management frameworks insufficient. In the late twentieth century the extension of Exclusive Economic Zones sought to reduce the number of international disputes, but for many migratory open- water fish species the issues remain severe.
These challenges foreshadowed many of the difficulties now faced in implementing global climate policies such as cap-and-trade systems. The larger the geographic range of the fish migration and the higher the number of governments involved in the negotiations, the more difficult have governance mechanisms been to negotiate. Like the efforts of climate-change agreements to address global emissions, these suffer from collective-action problems.
Most countries, including the United States, do not place an economy-wide tax on carbon, and instead have an array of greenhouse gas mitigation policies that provide subsidies or restrictions typically aimed at specific technologies or sectors … In the world of a Pigouvian tax, markets sort out the most cost-effective ways to reduce emissions, but in the world we live in, economists need to weigh in on the costs of specific technologies or narrow interventions.[64]
Kenneth Gillingham and James Stock
Climate change is the result of centuries of emissions generated by the very things that allow humans to achieve gains in their standard of living. Both the nature of climate change (multi-causal and wide-ranging) and the nature of the actors (diverse and under myriad legal systems with no worldwide decision-making body) make it not just the ‘greatest market failure ever known’ but perhaps the most difficult social problem to solve.
Many of the concepts presented throughout this publication apply to climate change. The atmosphere is the extreme example of a common-pool resource hard to protect with property rights that enable exclusion. Climate change stems from the global emissions produced by industrial users and individuals all around the world. While the results of the marginal increase in temperature may harm some regions more than others, whether they come from China or Norway, the pollutants have the same effects. Finally, even the results of the added pollutants today will not be felt for years. Other global environmental externalities, such as those of migratory fish stocks, are difficult to solve, but climate change is the most difficult. All humans benefit from solving the collective-action problem, but that only makes it more difficult because of the coordination needed.
Economists generally see the ideal solution as one of pricing the pollutants, ideally according to their social cost. For greenhouse gases they have created – and debated – the Social Cost of Carbon, which attempts to calculate the negative value of a unit of carbon dioxide (and equivalents).[65] It represents the value of the damage, so within this are the health and environmental costs of carbon, including in the future (which are discounted into a present value). Climate change generates changes in the future that must be accounted for in the present. Analogous to how firms discount their future streams of revenue and expected costs according to standard practices in corporate finance (because revenue in the future is worth less than revenue today), policy analysis uses assumptions about a social discount rate set by government to consider policy with implications in the future.[66]
Unsurprisingly, the Social Cost of Carbon is susceptible to many open debates about the values to be placed on parameters such as discount rates and a ‘statistical life’, not to mention the myriad scientific relationships relied on to estimate the relationship between emissions and events that cause damage. Given this, estimates vary, but a recent paper finds a value of $185 per ton.[67] This is notably higher than existing pricing schemes.[68]
Beyond the tricky question of what the price should be, of particular importance in relation to climate change is the epistemic function of markets. Pricing leads market participants to act in a new way based on information revealed by the price system. Pricing pollutants leads producers and consumers to mitigate the harm they occasion by more obviously incentivising the reduction of use but also, and perhaps more importantly, by adjusting behaviour on various margins – such as adopting new methods of production or spurring innovation. As many have noted, the considerations that consumers engage in with respect to the effect of their actions on the climate are particularly hard to work out. Are imported vegetables better or worse? Are the fewer resources needed to grow mature tomatoes in Morocco and Spain offset by the transportation miles? Beyond the core economic issues, well-meaning and well-informed consumers may attempt to act responsibly – even more so than some might predict – but the difficulty of knowing the right answer frustrates their efforts. A price on pollution, even if not the optimal price, performs a function that voluntary actions have difficulty achieving. Even if the price of carbon were too low as compared to the optimal price that reflected the social cost of the effects on the atmosphere for present and future generations, any price would lead to producers and consumers economising as relative prices changed. For instance, the price of the climate impact would filter into the decisions made along the tomato supply chain and the market would determine the trade- offs.
The political debates around both taxes and tradeable permits bring to the fore issues about take-up. While prices vary in typical markets, the inherently political nature of carbon markets means that businesses and green entrepreneurs are subject to political change. Governments want flexibility to change policy without legal constraints but market participants – especially in carbon credit schemes) – want the legal protections of real property rights.
Despite the growth of carbon pricing across the world, the United States has not followed suit. As Libecap writes:
Despite early optimism among some economists that cap and trade would become the template for US greenhouse gas (GHG) emission controls, that too has not been the case. The various federal and state regulatory efforts to address GHGs generally do not follow the national market-based approach in the SO2 phase-down, for example. Rather, the EPA, Congressional legislation, and Presidential executive orders outline a myriad of non-tradeable standards and restrictions on emissions from oil and gas use, coal and natural gas-fired power plants, industrial facilities, pipelines and other surface transport, along with subsidies and related tariffs for green energy development and electric vehicles.[69]
At least in terms of emissions reductions, climate-change prevention is a global public good: individuals cannot be excluded from the benefits of the reduction in emissions and the benefits that accrue are non-rival. This has led most to focus on binding legal actions between nations and regional groups. Despite this obvious logic, Ostrom has pointed out that many of the externalities are nested; that is, the control of pollution at the local level has benefits that accrue to the wider global populace.[70] This is of relevance for attempts to limit local air pollution.
In the absence of the ideal economic approach of taxing the pollutants themselves, these different features increase the difficulty of dealing with global warming in terms of reducing both the warming that occurs, and its impact, in some globally coordinated way. Much of the focus has understandably been on such agreements as those struck at Kyoto and Paris, but just as the warming outcome is the result of many varied decisions that take place without accounting for their negative effects, the limits to continued warming may result from decisions made at a less than global level (mainly national and subnational) and from technological developments achieved by entrepreneurs (both with and without the help of government policies).
Beyond the different responses to limit climate change, it is also worth considering that many of the mechanisms to limit the impact of natural disasters depend on subnational governance decisions and market actors more than national governments or international agreements. This is obvious at the time of the disaster and in the preparation for disasters but is also true of the broader framework of regulation that ensures reasonable decisions by individuals and firms. For instance, state policy should allow insurers to price according to risk, ensuring that both policyholders and insurers make the right investments,[71] yet in many cases insurance markets face politically motivated regulation. There is much room for improvement in management practices in resources where public bodies are in control, be that flood walls, firefighting equipment or controlled-burn policies in forests.[72] The cost of climate change will depend on the amount of warming but also on adaptation and preparation.
The last decade has seen large sums of money invested in the transition to green technology. Some of these investments are simply just market actors adopting new technology where profitable, and little different from the energy sector moving away from coal generation towards cleaner natural gas in the wake of the fracking revolution. Others are the result of state support, both explicitly as subsidy or implicitly as requirements on energy producers. Economists generally predict these acts of industrial strategy to prove poorly targeted and inefficient at reducing emissions; that is, achieving reductions at a greater cost than pricing the pollutants themselves via trading or tax. Research shows these inefficient ways of reducing greenhouse gases to be often more politically popular than relatively efficient alternatives.[73] Even in the United States the rollout of green energy generation has been hampered by environmental regulation in the form of the National Environmental Planning Act (1970) and state and local planning difficulties. If anything it has proved more difficult in the United Kingdom, despite the commitment to net zero.
In a period of increased fiscal strain across developed countries, market- based regulations can improve outcomes at greater efficiency by changing the incentives of regulated industries and disparate individuals. In much of the world, economic progress is still more important to many citizens than limiting environmental harm, especially when those reductions in harm accrue globally. The consequences of climate change are becoming clearer, and improvements must move from mere potential. The high-level approach to multinational agreements has much merit, but this section has emphasised some other elements of policy response that can help solve this difficult and complex problem.
The short answer is that command-and-control instruments have predominated because all of the main parties involved had reasons to favor them: affected firms, environmental advocacy groups, organized labor, legislators, and bureaucrats.[74]
Robert Stavins
Despite the theoretical advantages of a market-based approach to environmental problems that stresses property rights and market-based regulation, it often loses out in the political arena. For a time, these solutions seemed ascendant. A simplified version of this triumphant narrative is familiar to students of economics, but even with the rise of the economic framework for understanding and debating policy in the late twentieth century, much of the regulatory apparatus evolved prior to these developments. The continuing existence of much of the pre-existing regulatory framework is not the sole problem; in spite of new market-based regulation, much contemporary environmental policy suffers from the basic problems of command-and-control regulation.
This chapter has built on the work of historians of economics to show how those working in environmental economics in the past responded to theoretical and applied problems to craft market solutions to environmental issues inadequately addressed by regulatory measures. It has also pointed out some of the tendencies within the political sphere that have limited potential market solutions to environmental problems. While the topic is vast, two aspects of the stagnation can be identified.
One is at the intellectual level: despite the consensus for carbon pricing within economics, increased attention has been devoted to more radical transformations of the economy. At the level of more local pollution, political energy has shifted from technocratic reforms towards environmental justice, despite there being potential for many improvements to existing policy.
More generally, the incentives facing politicians and policymakers – shaped in part by the views of citizens and market participants – have limited the take-up of market-based reforms. Policies suggested by the framework are unpopular with politicians, regulators, and diverse interest groups, ranging from environmental activists and regulators to industry groups, as noted by Stavins in the mid-2000s. As with the FCC spectrum auctions mentioned above, market-based environmental policies often weaken policymakers’ control by reducing their discretionary authority and opportunities for visible regulatory intervention.
Environmental activists often prefer the perceived certainty of direct regulation, while regulators may resist mechanisms that diminish their bureaucratic role, and industry groups frequently favour targeted subsidies over market-wide pricing mechanisms. However, the continued effort towards limiting carbon emissions via a complex array of subsidies, mandates and bans risks the worst situation of all: spending enormous sums and constraining economic growth without achieving the emissions reductions that more efficient market-based approaches could deliver at lower economic cost.

In Mere Economics: Lessons For and From the Ordinary Business of Life, authors Carden and Fuller introduce caring Christians to economic thinking. Through breezy prose and pithy examples, the authors connect essential facts of faith to central ideas of economics. In fact, the book’s title is an homage to C.S. Lewis’s (1952) highly influential Mere Christianity – a work that conveys, with crystal clarity, the foundational elements of faith that are embraced by most denominations.
The same is true here: Carden and Fuller lay out the most central economic principles to illuminate issues like poverty, environmental stewardship, and other concerns that Christians take seriously. If your faith tells you that when you serve the poor you are serving your Master, and if economics helps you understand how to care for the poor even more effectively, why wouldn’t you want to know more about economics? The same line of thinking extends to creation care and other issues that lie at the heart of Christian concern. For example, if ‘the earth is the Lord’s, and the fulness thereof,’ and economics helps us be more effective caretakers, who wouldn’t want to know more economics?
The book’s outline is sensible, both for readers attracted to the topic as well as professors at Christian colleges and universities who might want to assign it as a companion reader to a traditional textbook. Its 14 chapters make it easily adaptable to a traditional US semester calendar of about 15 weeks.
In chapter one, ‘They Feast on the Abundance of Your House: Hobbesian Horrors and Walmart Wonders,’ the authors address what they refer to as the ‘Progress Puzzle’: How it is that, despite a growing population and a limited endowment of natural resources, humanity has nevertheless enjoyed breathtaking progress and prosperity? This section is reminiscent of the presentation found in Jason Brennan’s (2024) Why Not Capitalism?, in which Brennan lines up some of the most popular claims of market critics and then knocks each down via data.
Having introduced the Progress Puzzle – that humanity is fabulously better off than it was centuries ago, despite having little central planning in place – Carden and Fuller use chapter two, ‘Thinking about the Ordinary Business of Life,’ to lay out the core economic principles around which each of the remaining chapters will be formed. The chapter’s nine core principles include (1) economics is about making choices, (2) people are purposeful in their decisions, and (3) trade must be mutually beneficial because – if it weren’t – people wouldn’t do it. Along with each core principle, Carden and Fuller disarm the most common misconceptions of each; this back-and-forth rhetorical approach is very effective.
With these principles in hand, the authors use chapter three, ‘You Can’t Always Get What You Want: Our Great Economic Problem,’ to explain how human interaction – when voluntary and informed by the price system – leads to the remarkable outcomes outlined in chapter one. In fact, the authors indirectly make the audacious claim that it’s precisely because of scarcity that, over time, we realize the stunning outcomes in chapter one. If people didn’t face scarcity, they wouldn’t make decisions as carefully as they do when the stakes are high. And institutions like property rights lead to good decisions because they lay the penalty of a poor choice at the feet of the person who has the most to lose. The best line: ‘Don’t panic about scarcity anymore than you would panic about gravity.’ They both keep us grounded.
Chapters four and five extend chapter three by considering how far-flung resources, like the individual efforts of billions of individuals – with aspirations known only to them and using tiny bits of knowledge that may also be known only to them – are nevertheless powerfully channeled into a symphony of human activity. And most stunning of all, it’s a symphony with no conductor in charge. The analysis here relies heavily on thinkers like Adam Smith and F.A. Hayek. And chapter six reminds us that profits – if honestly earned – are the reward for serving others well; losses are the brutal consequences of not offering others something they need and want at a price they are willing to pay.
Having outlined this framework, the authors use the remainder of the book to apply it to a variety of policy questions and concerns. Chapter seven describes the inner workings of the labor market and argues that most outcomes are more humane and less outrageous than critics would have us believe, including the ‘gender-pay gap.’ Chapter eight considers whether, in some instances, a large firm that feels like a ‘monopoly’ might serve humanity quite effectively. To use the authors’ examples, Amazon, Google, and Walmart became successful because they served people well. And they can just as easily mess it up if they’re not vigilant (think MySpace and Yahoo!). The authors also note that the monopolies we hate most were often either created by the government or sanctioned by them.
Chapters nine through eleven deal with efforts of policymakers to legislate prices, legislate morality, or legislate production. Here the authors compellingly argue that, even if market mechanisms do not deliver ideal outcomes, they deliver outcomes preferable to those we would observe if government intervened to ‘improve upon’ those outcomes. And, of course, such interventions require compulsion: impeding or frustrating the decisions individuals otherwise would make.
Adding to this cautionary tale of government intervention, chapter twelve introduces the field of economics known as ‘public choice’: the strand of economics that treats voters, politicians, and bureaucrats just like it treats any other human subject, assuming that they act in their own self-interest just like anyone else does. For example, if politicians are motivated more by getting votes than by doing good, they might vote for policies people like rather than what might serve them best. And chapter thirteen returns to the ‘Progress Puzzle’ outlined at the beginning, having made the case – throughout the book – that it’s not really a puzzle at all: free individuals, created in God’s image, pursue creative acts of their own that lead to stunning long-term outcomes for humanity. The chapter also offers policy prescriptions for issues like pollution and resource depletion.
A wonderful feature of each of the preceding chapters is a concluding section that provides an application step for the ideas presented: ‘How Should We Then Live?’ This section of each chapter gives the reader a useful life lesson – something much needed from most economics books. And the final chapter of the book provides a similar point of reflection upon the entire work.
The book is thoughtful, reasonable, and winsome. Yet it’s not perfect.
First, the book seems unlikely to win over readers with grave moral concerns about capitalism. The authors may be right in their hopefulness, yet the style is too breezy to connect with readers uneasy with markets.
Second, every page is full of American cultural references and memes. While most of them connected with me, I see two liabilities: first, you really must be an American born within a specific time frame to be in on the jokes. I fear many references won’t connect with readers the authors are targeting (college students) and won’t connect with international readers, either. Also, you need to enjoy quirky humor to enjoy the book, but that seems like a gamble the authors are willing to take.
Lastly, because the book flows well, it might be challenging for a professor to assign individual chapters as stand-alone reading assignments because of references to earlier material.
Despite these limitations, I nevertheless recommend the book to anyone who thinks that economics isn’t interesting, is only about money, or that it’s not useful to people of faith. Carden and Fuller will likely change your mind.

Philip will bring a wealth of experience, knowledge and expertise in both business and theology. He is the ideal person to build on the solid platform laid by our Founding Director, Richard Turnbull in leading the work of the Centre.
I am deeply grateful for the opportunity to serve as Director. I am committed to building on the foundation laid by Lord Griffiths, Richard Turnbull and the whole CEME team, contributing a Christian perspective to economic debates.
Our vision has never been more relevant: a competitive market economy based on high ethical standards, where everyone can contribute with integrity to prosperity and the common good.
Over the coming months I look forward to engaging with CEME’s stakeholders and supporters – from economists, policymakers, and theologians to church leaders, entrepreneurs, and the business community – as together we advance this work.
Philip Krinks has a background in the academic study of enterprise, ethics and theology, in church ministry and in business consulting.
He read Classics and Philosophy at Magdalen College Oxford, and completed the management training programme at Citibank in London, before working in the Citi Foreign Exchange Sales & Trading business.
In 1998 he began a connection with Boston Consulting Group (BCG), which has lasted over 25 years. This included 5 years as Partner and Managing Director in their London Office, serving as Global Head of BCG’s Metals & Mining practice and undertaking pro bono projects with HM Treasury and the World Economic Forum.
In 2012 Philip left the BCG partnership to train for ministry in the Church of England. Subsequently, he served for 5 years as a Church of England Vicar, as Chaplain to the Bishop of Winchester and as Executive Director of the international social enterprise Pepal Foundation.
In addition to his Oxford MA, Philip holds an MBA from INSEAD, a PhD in Ethics from the University of London and an MA in Theology from King’s College London. He has published scholarly work on enterprise, ethics and theology.
I am delighted that Philip Krinks will succeed me as the Director of CEME. He will bring unique gifts and have unique opportunities. CEME was a remarkable vision that was in Lord Griffiths’ heart for many years. What a joy it was to bring that to fruition. We have built a great team and I know that they too will welcome Philip with open arms.”
Richard Turnbull is not an easy act to follow. But with a background of classics, philosophy, ethics, theology and the Church as well as practical experience in the world of consulting and financial trading, Philip Krinks is ideally placed to lead the Centre and I very much look forward to working with him.
Exploring a Christian perspective on contemporary issues of political economy
There are growing concerns that capitalism and democracy are in crisis. Despite the success of free markets in creating global prosperity over two centuries, the recent slowdown in growth in Western economies, the persistence of inflation, increasing economic inequality, financial instability and the explosion in debt have called into question the value of market capitalism. Moreover, trust has been eroded in liberal democracies because of dysfunctional governments, a perceived lack of commitment to truth and political leaders playing the game to the edge of legality. Added to these concerns are the growth of a post-modernist culture with steadily increasing social fragmentation, divisiveness and the lack of a unifying and accepted source of appeal.
We are living in the 21st century in Western societies in which religion has not just been replaced by secularism, but the one God of the Christian religion, with its deep roots in Judaism, has been replaced by the pluralism of the many gods of modernity. As a society we require those in leadership and authority in business and politics to have a moral compass and as Adam Smith set out regarding the virtue of prudence and Burke regarding the role of religion, our fellow citizens need values of honesty and sympathy if we are to seek the common good.
Against this background and under the auspices of the Centre we have decided to launch a series of colloquia in which to explore a Christian perspective on contemporary issues of political economy. On each occasion a small panel of experts will present their thoughts on the chosen topic, and other participants will then have the opportunity to make their own contributions to a free-flowing discussion. Participants will be invited from across the political spectrum and the number kept to around twenty. Following the links below you will find the contributions made to each meeting. We hope you find the papers stimulating.

Our fourth Fforestfach Colloquium focused on the subject of ‘Covenant’. It was held in Committee Room G in the House of Lords on the morning of Thursday, 26 June.
Our two principal speakers came from opposite sides of the political spectrum, both of whom have studied and written about the concept of covenant: Danny Kruger, MP, the Conservative member for East Wiltshire, and Lord (Maurice) Glasman, who founded the Blue Labour movement.
Danny Kruger published in 2023, Covenant: The New Politics of Home, Neighbourhood and Nation. In the book, he describes the key difference between the ‘social contract’ of Hobbes and Locke, and the ‘social covenant’ that he conceives: covenant, he writes, is a set of relationships built on love rather than on reason, an ‘artificial brotherhood’, expressing unconditional love between unrelated individuals, the foundational example of which is the covenant of marriage, ‘the union of two unrelated people that forms the nucleus of a new blood relationship, a family.’ Covenants also underly communities and nations.
Maurice Glasman, in his 2022 book, Blue Labour, points out that ‘…covenant requires that human beings are not treated as commodities, and that there is an inter-generational commitment to the common good between classes and regions based on the renewal of place… Neither the state nor the market is sufficient to generate a good society: it requires the renewal of society…’
Before the meeting, we had circulated a set of four questions on the topic for attendees to consider for themselves. We were delighted to be presented with some deeply thoughtful responses to those questions by our third contributor, Rabbi Benjy Morgan, who is the Chief Executive of the Jewish Learning Exchange in Golders Green. His reflections on our questions provided us with a number of very helpful Old Testament insights regarding the biblical concept of covenant.
As in our previous Fforestfach Colloquia, the invited audience of about 20 guests engaged enthusiastically with the presentations and the ensuing discussion, responding to points made by the speakers and also developing new lines of thought over the course of the morning.
Our third Fforestfach Colloquium took place in the House of Lords on the morning of Thursday, 30th January 2025, on the topic of Postliberal Political Economy, and brought together three speakers from academic, political, economic and media backgrounds.
Liberalism enjoyed a renaissance in the second half of the twentieth century. At the beginning of the 1960s, we saw the development of a socio-cultural liberalism on the left of UK politics, while in the 1980s, we experienced a growing economic liberalism from the right. Both those trends have given rise in the present century to the growth of post-liberalism, as explored in publications such as The Politics of Virtue (2016) by Adrian Pabst and John Milbank and Postliberal Politics (2021) by Adrian Pabst.
These publications, among others, provide a blueprint for a national, communitarian renewal, emerging from both the centre-left and centre-right. Importantly, postliberalism recognises the importance of the Christian heritage and Judeo-Christian ethics in providing a foundation for the renewal of a civic covenant, in the form of a partnership between generations and regions, and with nature.
At our Colloquium, we were addressed first by Professor Adrian Pabst of the University of Kent, who is also the Deputy Director of the National Institute for Social Research. His contribution pointed to the recurring crises experienced in advanced capitalist economies such as the UK, Germany, France, Italy, and Japan, which have struggled with low growth, high inflation and stagnant real wages ever since the 2008-09 financial crisis. Professor Pabst argued for a shift towards a social market economy, anchored in a greater sense of purpose and virtue.
He was followed by two distinguished speakers, his co-author, Dr John Milbank, Professor Emeritus at the University of Nottingham, and Miriam Cates, the former Conservative MP for Penistone and Stocksbridge in Yorkshire. They discussed alternative approaches to the postliberal economic challenges of our time, with Dr Milbank exploring the historical relationship between Christianity and Political Economy, suggesting that a truly Christian approach would seek to marry up what is practical and useful in modern economics with a more ancient humanism that does not surrender its ethical values. Miriam Cates, on the other hand, argued that many of the socio-economic crises we have experienced arise from the breakdown of Christian family values in the postliberal era, and called for a political economy based on a foundation of pro-family policies and a welfare state that encourages and supports families as a building block for a modern human society.
The second Fforestfach Colloquium took place in the House of Lords on Monday 29th April. We were privileged to welcome as our lead speaker an eminent professor from Harvard University, Professor Benjamin M. Friedman, who is the William Joseph Maier Professor of Political Economy and the former Chairman of the Department of Economics. Professor Friedman’s newest book, published in January 2021, is Religion and the Rise of Capitalism, and we invited Mr Friedman to speak to our invited audience about the theme of his book, to be followed by two highly-respected commentators, Professor Emeritus Forrest Capie of the Bayes Business School, and Lord (Mervyn) King of Lothbury, former Governor of the Bank of England.
Centre for Enterprise, Markets and Ethics
In a world where academic publications often descend into the microscopic world of nuance, there is a detectable trend towards volumes with the laudable objective of providing the aspiring amateur with an introductory overview of a subject. The author of Profit has undoubtedly taken this path and pitched for the macro-view: we find ultimately that that the intention of the book is to trace ‘the environmental aspects of capitalism’s germination and growth through human history’ (page 253).
We’re inducted into the argument via the ubiquitous ‘palm-sized technological marvel’ which is simultaneously the ‘environmental crime that is the Smartphone’ (page 2). At the outset, Stoll proposes to resolve this paradox by allowing the reader to judge where responsibility lies between humanity or that subset of guilty humans comprising the ‘capitalists and corporations’ who define the ‘Capitalocene’ (page 3). The verdict turns upon what the author calls ‘profit’. However, while from the outset it is clear that ‘profit’ is not to be equated with a synonym for capitalism, no more precise explanation is forthcoming and in that void, greater experience with the text encourages the reader towards a tentative definition of ‘cui bono?’.
Arranged in chronological order from the dawn of humanity, each chapter seeks to illustrate (if not fully illuminate) typical characteristics of the relationship between human activity driven by ‘profit’ and the natural resources involved. The deliberate choice to define ‘profit’ ambiguously ensures that any – indeed all – human activity becomes material for this study. While this may in itself appear ambitious, the decision to cover the entirety of human existence, from the first dawn of the Hominim, cannot help but have an echo of Shakespeare’s ‘vaulting ambition, which o’erleaps itself’. To navigate this scope would seem to necessitate a rigorous approach with a solid ‘backbone’ argument across the work upon which can hang the various elements of the narrative. Instead, the author has chosen to use a join-the-dots approach supported by potted biographies of a handful of individuals or publications which are used across the ages in a manner similar to posts carrying a string of lamps.
The opening chapter covers the first few hundred thousand years of Hominim activity and is naturally lacking in data points. Stoll runs this period of study up to the fifteenth century AD/CE; when the second chapter switches the focus to ‘Trade and Empire’. This division is a missed opportunity to explore the substantial trading empires of Greece and Rome; instead, with Columbus as the locus for the second period of study this enables the introduction of ‘America’, but brings in its wake an atypical focus on the development of the Genoese Republic, which is subsequently proposed as an exemplar. Chapter Three concerns ‘Coal and Machines’ – although first through the experience of the fifteenth century Dutch, introducing the first of many (ultimately disconcerting) chronological hops back and forth, and odd since the author suggests a reliance of the Dutch empire on wind-power, before moving onto the English, ‘Plantation Capitalism’, sugar and (unusually, perhaps) the contributions of the Scottish Presbyterians who, we are informed, ‘disproportionally administered the British Empire … and dominated shipping and trade’ (page 71). Chapter Four is formed around ‘Steam and Steel’, which acts as the bridge to introduce Andrew Carnegie, whose early life coincided with the Bessemer Process, but more fortuitously was of Scottish decent, which facilitated his career in an age of imperialism and industrial capitalism, soon to become a global phenomenon.
Chapter Five adds environmentalism to the narrative – in the last half of the nineteenth century and exactly halfway through the work. The topic is introduced through two works which Stoll considers pivotal: George Marsh’s Man and Nature and William Jevons’ The Coal Question. Stoll makes the claim that these are ‘books that shook the confidence of a complacent public’ (page116), which appears bold given their subsequent descent into obscurity – almost immediately, in Jevons’ case. While Marsh did later privately republish his text under a fresh title, neither of these prolific authors considered their topic of sufficient importance to engage with it again, and indeed the Stanford Encyclopedia of Philosophy manages to devote over six thousand words to Jevons without a mention of his pamphlet.
The focus moves through the twentieth century on the back of what Stoll terms ‘consumer capitalism’ – the origins of which are ascribed to (consecutively) the availability of mass finance, petroleum, electricity, plastic, disposable products and finally, advertising. Although this caused an increase in ‘waste’ and had a brief pause in the United States (the Wall Street crash, here described as a product of capitalism rather than speculation), this continues through the twentieth century (global conflicts are not discussed) until the rise of the bright and buoyant era known to historians as the Cold War, in which the motor car and electronics drove postwar prosperity hand in hand with central ‘government activism’, until this was attacked by ‘alarmed … wealthy corporate leaders’ who created ‘a propaganda network to promote weak government and low taxes’ (page 176).
Post-1970, the narrative in the chapter ‘Selling Everything’ leaps to hyper-market operations – exampled by Walmart and the web giant Amazon – both of which enjoyed unique success and so would be candidates for the atypical rather than the representative. Their success is set against the stagnation and decline in the US economy, a claim illuminated by the notion that more people entered the service sector in the eight years from 1973 to 1981 than the auto and steel industries combined. However, the author had already flagged the death of nineteenth century ‘industrial capitalism’ before the Second World War, so the shift towards ‘consumer capitalism’ would seem to be entirely in line with expectations, given the central notion of this volume that all and any economic activity is ‘capitalism’. Once again, a handful examples from across the globe are collated to suggest negative consequences from various categories of causes – coal and petroleum are singled out, which seems odd since coal would have presumably featured in the ‘industrial capitalist’ period (however ill-defined) – rather than that of the consumer or late consumer capitalist periods.
It is only at the end of Chapter Eight that we finally begin to see an attempt to discuss ‘Pollution, Air and Climate’; CFCs, Ozone depletion, permafrost methane, and oceanic acidification are introduced and concluded in rather less than one page (pages 223-224).
The last chapter is devoted to the formation of the Global Environmental movement, again through exploring the impact of two publications. The first, Silent Spring by Rachel Carson, is widely acknowledged as perhaps the most important environmental book of the twentieth century. The second, Only One Earth, is Barbara Ward’s influential contribution to sustainable development; both Carson’s lapsed Reformed Protestant heritage and Ward’s hybrid Quaker-Catholicism are given an airing: notwithstanding these volumes remain edifying to all readers. A summary of American developments post-World War II is joined to the rise of the West German Green Party in the 197Os, and the impact of the Seveso, Bhopal and Chernobyl accidents in contributing to a wider spread of environmental concern and the European rise of support for anti-nuclear groups. Half of the very short summary of the ‘Rise of the Greens’ is once again devoted to the influence of a (northern, Reformed) Protestant heritage, while in Catholic countries environmentalism becomes a ‘non-religious, non-moralistic environmental movement’ (page 239): some examples would help forward this claim, not least as it is contradicted by Stoll’s conclusion that in 2015 (and more than forty years after publication) Ward’s work influenced the pronouncements of Pope Francis (page 241).
Stoll’s concluding chapter states that the key question is: ‘does it profit us when someone else makes a profit?’ (page 251). He suggests – perhaps unsurprisingly – that the answer is unclear. However, what is missing here – as in the entire work – is a decomposition of what is meant by the question. Instead, what is presented – as in the entire work – merely adds fog to the lens. Stoll makes the claim that ‘in the pre-Modern Christian West profit entailed a moral calculus’ (page 251). This is both bold and belated: if the purpose of Profit was intended to be an exploration of this theme, it would have gained some coherence – but would have lost any right to be considered ‘An Environmental History’.
Stoll’s summary conclusion is disappointingly (but perhaps not surprisingly) a mirror of the introduction: capitalism (whatever the form in which it is labelled) is rooted in human nature, and the outcomes – including ‘profit’ – have always (historically) been realised ‘at nature’s expense’ (page 252). After 250 pages, the author’s final warning is both stark and something of a surprise: ‘we stop the machinery of consumer capitalism at our peril’ (page 254). Hope is at hand, however, evidenced by an increasing appetite for ‘experiences’ rather than ‘stuff’, with the implication that cruises, travel to foreign countries, climbing mountains, and diving coral reefs will prove less of an environmental issue. There is even a thumbs up for games on Smartphones. It is unfortunate that at the last, the focus falls entirely upon the consumption habits not of the globe, but on one segment of the American population.
Almost inevitably the overall tone of the work feels rushed – indeed superficial. Arguments do not have the space to be outlined, let alone developed, and thus the whistle-stop tour becomes a giddy and frustrating experience. Indeed, the major weakness arises from the absence of any sustained, central argument. Instead, often poorly constructed polemic is substituted. Possibly the strangest statement occurs in the conclusion, where the reader is invited to contemplate how very different ‘Modern consumer capitalism’ might have been ‘had the Genoese prevailed at the War of Chioggia’ (page 252): it is not easy to imagine a reversal of historic events which would have made less of a ripple beyond the late fourteenth century Adriatic. In the haste to apply the broad brush, some odd images appear: the period noted by historians for its tranquillity and known as the Belle Epoque is described as ‘the tumultuous era between the 1880s and the mid-1910s’ (page 137).
The stated focus on Western Europe and the United States of America is inconsistent. Many examples are typical of the USA but not Europe, while China and Lake Nasser are the examples chosen to illustrate the possible negative effects of a building dams – irrespective of the atypical nature of both Chinese construction techniques, the Sahara sun and the relationship between Egypt and the Nile (page191).
Another oddity is the frequent intrusion of a religious (specifically Christian Presbyterian) theme. Many of the individuals featured are sprinkled with a reference to a ‘Puritan heritage which shaped their analysis and solutions’, even if the author immediately acknowledges that (as in the case of Jevons) he ‘neither embraced nor disavowed the religion of his forefathers’ or the ‘quite religious’ Marsh ‘who rarely attended’ (page 121). As Dr Stoll has previous published a book entitled Protestantism, Capitalism and Nature in America this may perhaps be inevitable, but it is ultimately regrettable since a more general discussion of the nature of profit fragmented through the lens of world religions – or even that of Christianity through the ages – is entirely missing.
Perhaps more importantly for ‘An Environmental History’, there is also very little history of the environment – rather, a small list of negative consequences of human existence are regularly recycled (forests denuded, rivers silted, air polluted) as the consequences of a wide range of activities. While the telegraph, mining, smelting, manufacturing, shipbuilding and consumerism are singled out for particular approbation at various points, the conclusions are largely homogenous: mining makes as mess; processing (from refining sugar to forging metal) burns wood; some people in various places used slave or indentured labour, while others traded or purchased the outputs, and both sea and air quality have got worse as both populations and the reach of advertising have grown.
However unremarkable these conclusions, it may be that there exists an audience for whom it needs re-stating. Given the almost hubristic scope and ambition, to note a lack of supporting data might appear to miss the point. But while the book scatters dates in profusion, there are no data points at all, nor graphs nor tables to illustrate any point. The illustrations are therefore all not only biographical but somewhat anecdotal, while the photograph illustrating Brazilians waving placards including ‘Pray for Amazon’ (page 241) sits somewhat uncomfortably with the earlier profile of Jeff Bezos.
Curiously, the author always falls short of a polemic against capitalism – and in the absence of supporting data it is hard to come to any other conclusion. The central, if missing, element in this work was fully identified in Ward’s work – engagement with the question: what is the mechanism by which we balance the (inner) individual’s right to an adequate standard of living with the (outer) limit of what the Earth can sustain?
An experienced academic editor was wont to point out to aspiring authors that it is ‘always easier to write a book than a paper’. The message was that, while structure – founded on a clear purpose and supported by evidenced argument – remains essential to both, the longer format can withstand a greater burden. Dr Stoll would appear not to have received this advice, and while possibly a good man with good intentions, unfortunately ‘An Environmental History’ was never a very good idea, and it has not resulted in a good book.
‘Profit: An Environmental History’ by Mark Stoll was published in 2024 by Polity (ISBN 978-1-50-953324-4). 280pp.
