Fair Innings? The Utilitarian And Prioritarian Value Of Risk Reduction Over A Whole Lifetime, Matthew D. Adler, Maddalena Ferranna, James K. Hammitt, Nicolas Treich

Faculty Scholarship

The social value of risk reduction (SVRR) is the marginal social value of reducing an individual’s fatality risk, as measured by some social welfare function (SWF). This Article investigates SVRR, using a lifetime utility model in which individuals are differentiated by age, lifetime income profile, and lifetime risk profile. We consider both the utilitarian SWF and a “prioritarian” SWF, which applies a strictly increasing and strictly concave transformation to individual utility.

We show that the prioritarian SVRR provides a rigorous basis in economic theory for the “fair innings” concept, proposed in the public health literature: as between an older individual …

A Better Calculus For Regulators: From Cost-Benefit Analysis To The Social Welfare Function, Matthew D. Adler

Faculty Scholarship

The “social welfare function” (SWF) is a powerful tool that originates in theoretical welfare economics and has wide application in economic scholarship, for example in optimal tax theory and environmental economics. This Article provides a comprehensive introduction to the SWF framework. It then shows how the SWF framework can be used as the basis for regulatory policy analysis, and why it improves upon cost-benefit analysis (CBA).

Two types of SWFs are especially plausible: the utilitarian SWF, which sums individual well-being numbers, and the prioritarian SWF, which gives extra weight to the well-being of the worse off. Either one of these …

Nashbots: How Political Scientists Have Underestimated Human Rationality, And How To Fix It, Daniel Enemark, Mathew D. Mccubbins, Mark Turner

Faculty Scholarship

Political scientists use experiments to test the predictions of game-theoretic models. In a typical experiment, each subject makes choices that determine her own earnings and the earnings of other subjects, with payments corresponding to the utility payoffs of a theoretical game. But social preferences distort the correspondence between a subject’s cash earnings and her subjective utility, and since social preferences vary, anonymously matched subjects cannot know their opponents’ preferences between outcomes, turning many laboratory tasks into games of incomplete information. We reduce the distortion of social preferences by pitting subjects against algorithmic agents (“Nashbots”). Across 11 experimental tasks, subjects facing …

Priority For The Worse Off And The Social Cost Of Carbon, Matthew D. Adler, David Anthoff, Valentina Bosetti, Greg Garner, Klaus Keller, Nicolas Treich

Faculty Scholarship

The social cost of carbon (SCC) is a monetary measure of the harms from carbon emission. Specifically, it is the reduction in current consumption that produces a loss in social welfare equivalent to that caused by the emission of a ton of CO2. The standard approach is to calculate the SCC using a discounted-utilitarian social welfare function (SWF)—one that simply adds up the well-being numbers (utilities) of individuals, as discounted by a weighting factor that decreases with time. The discounted-utilitarian SWF has been criticized both for ignoring the distribution of well-being, and for including an arbitrary preference for earlier generations. …

Justice, Claims And Prioritarianism: Room For Desert?, Matthew D. Adler

Faculty Scholarship

Does individual desert matter for distributive justice? Is it relevant, for purposes of justice, that the pattern of distribution of justice’s “currency” (be it well-being, resources, preference-satisfaction, capabilities, or something else) is aligned in one or another way with the pattern of individual desert?

This paper examines the nexus between desert and distributive justice through the lens of individual claims. The concept of claims (specifically “claims across outcomes”) is a fruitful way to flesh out the content of distributive justice so as to be grounded in the separateness of persons. A claim is a relation between a person and a …

Consumption, Risk And Prioritarianism, Matthew D. Adler, Nicolas Treich

Faculty Scholarship

In this paper, we study consumption decisions under risk assuming a prioritarian social welfare function, namely a concave transformation of individual utility functions. Under standard assumptions, there is always more current consumption under ex ante prioritarianism than under utilitarianism. Thus, a concern for equity (in the ex ante prioritarian sense) means less concern for the risky future. In contrast, there is usually less current consumption under ex post prioritarianism than under utilitarianism. We discuss the robustness of these results to learning, and to other forms of prioritarian social welfare functions.

Happiness Surveys And Public Policy: What’S The Use?, Matthew D. Adler

Faculty Scholarship

This Article provides a comprehensive, critical overview of proposals to use happiness surveys for steering public policy. Happiness or “subjective well-being” surveys ask individuals to rate their present happiness, life-satisfaction, affective state, etc. A massive literature now engages in such surveys or correlates survey responses with individual attributes. And, increasingly, scholars argue for the policy relevance of happiness data: in particular, as a basis for calculating aggregates such as “gross national happiness,” or for calculating monetary equivalents for non-market goods based on coefficients in a happiness equation.

But is individual well-being equivalent to happiness? The happiness literature tends to blur …

Harsanyi 2.0, Matthew D. Adler

Faculty Scholarship

How should we make interpersonal comparisons of well-being levels and differences? One branch of welfare economics eschews such comparisons, which are seen as impossible or unknowable; normative evaluation is based upon criteria such as Pareto or Kaldor-Hicks efficiency that require no interpersonal comparability. A different branch of welfare economics, for example optimal tax theory, uses “social welfare functions” (SWFs) to compare social states and governmental policies. Interpersonally comparable utility numbers provide the input for SWFs. But this scholarly tradition has never adequately explained the basis for these numbers.

John Harsanyi, in his work on so-called “extended preferences,” advanced a fruitful …

Vote-Trading In International Institutions, Ofer Eldar

Faculty Scholarship

There is evidence that countries trade votes among each other in international institutions on a wide range of issues, including the use of force, trade issues and elections of judges. Vote-trading has been criticized as being a form of corruption, undue influence and coercion. Contrary to common wisdom, however, I argue in this paper that the case for introducing policy measures against vote-trading cannot be made out on the basis of available evidence. This paper sets out an analytical framework for analyzing vote-trading in international institutions, focusing on three major contexts in which vote-trading may generate benefits and costs: (1) …

Does Falling Smoking Lead To Rising Obesity?, Jonathan Gruber, Michael D. Frakes

Faculty Scholarship

The strong negative correlation over time between smoking rates and obesity have led some to suggest that reduced smoking is increasing weight gain in the U.S.. This conclusion is supported by the findings of Chou et al. (2004), who conclude that higher cigarette prices lead to increased body weight. We investigate this issue and find no evidence that reduced smoking leads to weight gain. Using the cigarette tax rather than the cigarette price and controlling for non-linear time effects, we find a negative effect of cigarette taxes on body weight, implying that reduced smoking leads to lower body weights. Yet …

Beyond Efficiency And Procedure: A Welfarist Theory Of Regulation, Matthew D. Adler

Faculty Scholarship

Normative scholarship about regulation has been dominated by two types of theories, which I term "Neoclassical" and "Proceduralist." A Neoclassical theory has the following features: it adopts a simple preference-based view of well-being, and it counts Kaldor-Hicks efficiency as one of the basic normative criteria relevant to the evaluation of regulatory programs. A Proceduralist theory is concerned, not solely with the quality of regulatory outcomes, but also with the governmental procedures that produce these outcomes: it gives intrinsic significance to the procedures that regulatory bodies follow. (One example of a Proceduralist theory is the civic republican theory of regulation advanced …

Implementing Cost-Benefit Analysis When Preferences Are Distorted, Matthew D. Adler, Eric A. Posner

Faculty Scholarship

Cost-benefit analysis is routinely used by government agencies in order to evaluate projects, but it remains controversial among academics. This paper argues that cost-benefit analysis is best understood as a welfarist decision procedure and that use of cost-benefit analysis is more likely to maximize overall well-being than is use of alternative decision-procedures. The paper focuses on the problem of distorted preference. A person's preferences are distorted when his or her satisfaction does not enhance that person's well-being. Preferences typically thought to be distorted in this sense include disinterested preferences, uninformed preferences, adaptive preferences, and objectively bad preferences; further, preferences may …

Rethinking Cost-Benefit Analysis, Matthew D. Adler, Eric A. Posner

Faculty Scholarship

This paper analyzes cost-benefit analysis from legal, economic, and philosophical perspectives. The traditional defense of cost-benefit analysis is that it maximizes a social welfare function that aggregates unweighted and unrestricted preferences. We follow many economists and philosophers who conclude that this defense is not persuasive. Cost-benefit analysis unavoidably depends on controversial distributive judgments; and the view that the government should maximize the satisfaction of unrestricted preferences is not plausible. However, we disagree with critics who argue that cost-benefit analysis produces morally irrelevant evaluations of projects and should be abandoned. On the contrary, cost-benefit analysis, suitably constrained, is consistent with a …
