Individuals can rationally pursue their interests without the preferences and marginal utilities that have long taken center stage in economics. Economics without preferences lays out the microeconomics of individual behavior, markets, and welfare when agents cannot always come to judgment. Although economic theory has claimed that self-interest requires agents to form preferences, individuals can protect themselves from harm by refusing to trade options they cannot rank. Many of the anomalies uncovered by behavioral economics – from status quo bias to loss aversion – thus have a rationality design. The absence of preferences also resolves the puzzle that classical economic agents are almost never indifferent between options whereas real-world agents often are. When individuals cannot judge trade-offs, gaps appear between the marginal valuations of gains and losses. These gaps explain why market prices can be volatile and render orthodox efficiency criteria indecisive. Policymakers will no longer be able to pin down an optimal provision of public goods. Traditional schemes that try to harness preference information to compensate agents harmed by economic change will allow virtually any decision to qualify as efficient. Governments should instead spur productivity growth, the main benefit capitalism can deliver, while shielding agents from the price upheavals that result.
Economists have long studied policy choice by social planners aiming to maximize population welfare. Whether performing theoretical studies or applied analyses, researchers have generally assumed that the planner knows enough about the choice environment to be able to determine an optimal action. However, the consequences of decisions are often highly uncertain. Discourse on Social Planning under Uncertainty addresses the failure of research to come to grips with this uncertainty. Combining research across three fields – welfare economics, decision theory, and econometrics – this impressive study offers a comprehensive treatment that fleshes out a 'worldview' and juxtaposes it with other viewpoints. Building on multiple case studies, ranging from medical treatment to climate policy, the book explains analytical methods and how to apply them, providing a foundation on which future interdisciplinary work can build.
Economics without Preferences lays out a new microeconomics – a theory of choice behavior, markets, and welfare – for agents who lack the preferences and marginal judgments that economics normally relies on. Agents without preferences defy the rules of the traditional model of rational choice but they can still systematically pursue their interests. The theory that results resolves several puzzles in economics. Status quo bias and other anomalies of behavioral economics shield agents from harm; they are expressions rather than violations of rationality. Parts of economic orthodoxy go out the window. Agents will fail to make the fine-grained trade-offs ingrained in conventional economics, leading market prices to be volatile and cost-benefit analysis to break down. This book provides policy alternatives to fill this void. Governments can spur innovation, the main benefit markets can deliver, while sheltering agents from the upheavals that accompany economic change.
Animal welfare is often ignored in decision-making, despite widespread agreement about its importance. This is partly because of a lack of quantitative methods to assess the impacts of policies on humans and nonhumans alike on a common scale. At the same time, recent work in economics, philosophy, and animal welfare science has made progress on the fundamental theoretical challenge of estimating the well-being potential of different species on a single scale. By combining these estimates of each species’ well-being potential with assessments of how various policies impact the quality of life for these species, along with the number of animals affected, we can arrive at a framework for estimating the impact of policies on animal health and well-being. This framework allows for a quantifiable comparison between policies affecting humans and animals. For instance, it enables us to compare human QALYs to animal QALYs tailored to specific species. Hence, the intrinsic value of animal welfare impacts of policies can be monetized on the same scale as market and non-market impact for humans, facilitating benefit–cost analysis. Many challenges remain though, including issues of population ethics, political feasibility, and new complexities in addressing equity and uncertainty.
First, Mahtani argues that both in the game The Mug and in the Sleeping Beauty we should not defer to a trusted person under a particular designation if they do not self-identify under this designation. This invites a more complex Reflection Principle. I respond that there are more parsimonious ways to avoid the challenges posed to the Reflection Principle. Second, Mahtani argues that preferences create a hyperintensional context, which poses a challenge to the Ex-Ante Pareto Principle that can be averted by supervaluation. I respond that such an appeal to supervaluation would block randomization as a fair allocation device.
In Chapter 7, I discuss the latest crisis of capitalism and Amartya Sen’s journey to rescue capitalism from the capitalists. I begin by discussing the increasing vulnerability of capitalist societies at the end of the twentieth century due to the deregulatory environment encouraged by the Chicago School. I use Karl Polanyi’s double-movement theory to explain the rise of the Chicago School and its assault on the “relationship capitalism” that had evolved in the postwar period. While the new “investor capitalism” was successful at unleashing the power of the market, it also increased the vulnerability of capitalist societies to opportunistic self-interest. This increased vulnerability was fully realized in the 2007–08 mortgage-backed security crisis that nearly collapsed the global financial system. After describing the near collapse of the global financial system, I discuss the implications of the collapse for the neoclassical theory out of Chicago. This leads to a discussion of Amartya Sen’s journey from India to the West to rescue capitalism from the capitalists. This discussion introduces the role of the East in the development of capitalism and its future promise. I conclude by discussing Sen’s critique of capitalism based on Adam Smith’s original moral foundation.
Much business ethics and corporate social responsibility literature suggests, implicitly or explicitly, that firms ought to engage in activities that can be characterized as philanthropy, namely, expending resources beyond what is required by law and market norms to promote others’ welfare at the expense of firm profits. However, this literature has struggled to provide a normative framework for evaluating corporate philanthropy, although scholars have noted that such expenditures can potentially remedy market failures and provide public goods more efficiently. I articulate two specific rationales that can justify corporate philanthropy based on considerations of welfare economics: 1) firms making strategic but high-risk investments in activities that are likely to generate positive externalities even if they prove unprofitable and 2) firms possessing a strong comparative advantage in their ability to address a social problem at lower social cost. Moreover, these rationales can be evaluated by a concept I develop called the philanthropy multiplier, indicating the ratio of net positive externalities to net costs. I suggest that firms consider publicizing their philanthropy multipliers, and I discuss theoretical and practical implications.
Even where willingness-to-pay as a measure of welfare impact is adjusted for diminishing marginal utility, welfare economics is shown to favour policies that add to the life expectancy or that enhance the quality of life of persons who are already better-off. I propose an alternative, Equal Respect methodology, under an axiomatic claim that at the point of decision the prospective life years of all individuals are of equal intrinsic social value. This justifies equal valuation of risk mitigation across all persons; similarly, all appraised impacts should be scaled to accord equal respect to difficult but no-less-valuable lives.
Since the publication of the seminal book Nudge by Thaler and Sunstein, several critics have highlighted preference endogeneity as a serious obstacle to nudging. When individuals hold preferences that are dynamic and endogenous to the nudge frame, it is unclear what the normative benchmark for libertarian paternalistic policies should be. While acknowledging this issue, the pro-nudging camp has not yet sufficiently addressed it. This article aims to fill this void by presenting a conditional defence of nudging when preferences are endogenous. We explain the learning process through which individuals establish ‘agentic’ preferences: preferences that are sufficiently stable, reasonable, autonomous and associated with organismic well-being to ground the ‘welfare’ principle of libertarian paternalism. To describe this process, we draw on theories from psychological science, in particular self-discrepancy theory and self-determination theory. We argue that agentic preferences are not only welfare-relevant and thus appropriate to libertarian paternalism but can also be identified by choice architects.
Most cost-benefit analyses assume that the estimates of costs and benefits are more or less accurate and unbiased. But what if, in reality, estimates are highly inaccurate and biased? Then the assumption that cost-benefit analysis is a rational way to improve resource allocation would be a fallacy. Based on the largest dataset of its kind, we test the assumption that cost and benefit estimates of public investments are accurate and unbiased. We find this is not the case with overwhelming statistical significance. We document the extent of cost overruns, benefit shortfalls, and forecasting bias in public investments. We further assess whether such inaccuracies seriously distort effective resource allocation, which is found to be the case. We explain our findings in behavioral terms and explore their policy implications. Finally, we conclude that cost-benefit analysis of public investments stands in need of reform and we outline four steps to such reform.
Chapter 17 analyzes his efforts, throughout his scientific career, to measure welfare. Measurement was crucial for his intellectual program. While measurement often succeeded in his early career with the development of business-cycle statistics, the measurement of welfare remained unattainable. The measurement of welfare was important because it would allow a scientific comparison of the welfare levels between different individuals, and thus of the degree of inequality. He wanted to use that as a basis for his scientific notion of justice. In his efforts he went against a general consensus in economics that interpersonal comparisons of welfare were beyond the reach of economic science. Tinbergen took up a chair in Leiden after his retirement and attempted to develop a collaboration with Bernard van Praag and Arie Kapteyn, but their joint approach found little support in the wider economics community. Nonetheless, the failure is interesting because it provides insight into the way in which moral concerns became more important later in Tinbergen’s career, how crucial measurement was to him, and because his attempts foreshadowed later approaches in economics to measure capabilities and happiness. Most importantly, it demonstrates how he hoped that science could inform normative concepts such as justice.
I comment on Sunstein's paper proposing ‘Hayekian behavioural economics’. In essence, Sunstein is merely renaming a familiar approach to normative economics, initiated in Sunstein and Thaler's seminal 2003 paper. I argue that this approach cannot fairly be described as in the spirit of Hayek's work. Sunstein's approach is based on a ‘constructivist’ conception of rationality that Hayek consistently criticized. Although both Hayek and Sunstein address ‘knowledge problems’, the two problems are fundamentally different. I develop what I claim are truly Hayekian critiques of Sunstein's claim that fuel economy mandates can be more Hayekian than carbon taxes.
We re-examine Pigou’s ethics in welfare economics with respect to welfarist or non-welfarist (more broadly, utilitarian or non-utilitarian) concepts based on various perspectives, such as incommensurability among utility and people, basic need information approach, non-welfarist justification of the national minimum, and methodological individualism in axiology. Consequently, we could detect certain non-welfarist approaches in his welfare economics, which squarely challenges the orthodox understanding of his works. We can assert that the deviation from simple welfarism was a result of practical considerations. Furthermore, apart from the dichotomy about welfarist and non-welfarist viewpoints, we present novel assessments of Pigou’s welfare notion: a hybrid strategy for the enhancement of people’s well-being. We show that his overall welfare idea involves both subjective and objective accounts and has a three-layered welfare strategy: bare and raw preferences turn into educated and refined ones via objective needs.
John Hicks played a crucial role at birth of the “new” welfare economics founded on the informational basis of interpersonally non-comparable and ordinal utilities. Toward the end of the 1950s, however, Hicks took a bold step by declaring his farewell to the welfarist informational basis of normative economics altogether. The purpose of this paper is to gauge the depth and reach of Hicks’s farewell to the welfaristic approach to normative economics.
This innovative history of welfare economics challenges the view that welfare economics can be discussed without taking ethical values into account. Whatever their theoretical commitments, when economists have considered practical problems relating to public policy, they have adopted a wider range of ethical values, whether equality, justice, freedom, or democracy. Even canonical authors in the history of welfare economics are shown to have adopted ethical positions different from those with which they are commonly associated. Welfare Theory, Public Action, and Ethical Values explores the reasons and implications of this, drawing on concepts of welfarism and non-welfarism developed in modern welfare economics. The authors exemplify how economic theory, public affairs and political philosophy interact, challenging the status quo in order to push economists and historians to reconsider the nature and meaning of welfare economics.
Social choice is concerned with the selection of an ideal (or social) option, which can be a so-called ‘social state’, or a social ‘utility’, or a social ‘preference’, or a social choice ‘set’, on the basis of individual utilities, or individual utility functions, or individual preferences, or individual choice sets, or individual choice functions. A number of scholars have outlined the limited aspect of the notion of utility, including, notably and pre-eminently, Amartya Sen and Martha C. Nussbaum. Although they did not put it in such a strong phrase, the basic idea is to replace the notion of utility by the notion of capability (leaving aside ‘happiness’, a notion which for many is hardly distinguishable from utility). As has been remarked by Mozaffar Qizilbash, the development of the capability approach has been focused on the capability of an individual; and the idea of amalgamating or aggregating individual data is consubstantial with social choice. The purpose of this text is to propose some preliminary ideas regarding the aggregation of individual capabilities.
In the framework of a critical illustration of the contemporary history of economics, this chapter recalls the foundations of utilitarianism and the ethics of consequences and provides a survey of research on income inequalities. Then it provides a critical history of welfare economics. It illustrates Sen’s notion of capabilities. It opposes conservative, revolutionary and reformist views on the evolution of capitalism and, finally, discusses a rather unusual topic, the economists’ ethics.
The system accounts in the previous chapters provide a description of the developments of the environment, society and economy as well as the distribution. But the accounts do not answer the question: Are things getting better? In the Global Quality Accounts (GQA), the data from the system accounts are assessed using a quality perspective. In economics, welfare economics and the capital approach are most common, but there are many others as well, from social sciences or natural sciences. There is no perfect approach, just multiple ways of looking at systemic progress. Each of the systems leads to a quality indicator, which provide society with different views.
The previous chapters have shown that there is one powerful community (“the GDP multinational") which is being challenged by a heterogeneous and weakly organised community (“the Beyond-GDP cottage industry). The ever-expanding range of Beyond-GDP initiatives will not lead to success however. A new strategy is based on the GDP success story and aims to create an institutionalised community with a clear goal and coherent structure based on a common language. The chapter argues that the community should not be based on the SDGs, green accounting or the SEEA. It also argues that the community should not be based on economic terminology and theory but rather on multidisciplinary building blocks such as stock/flow accounting, networks and limits. The aim of the community is to enhance well-being and sustainability and one of its most important features is its common language: the System of Global and National Accounts (SGNA). The SGNA has four system accounts (environment, society, economy and distribution), which describe how the systems are developing. However, this does not yet tell people whether the developments are good or bad. This is left to the quality accounts.
