What (If Anything) Can Economics Say About Equity?, Daniel A. Farber

Daniel A Farber

Does economics have anything to teach us about the meaning of fairness? The leading practitioners of law and economics disagree. Judge Richard Posner argues that economics is largely irrelevant to distributive issues. Posner maintains that the most useful economic measure of social welfare is cost-benefit analysis (which he calls wealth maximization). But, he observes, this economic measure "ratifies and perfects an essentially arbitrary distribution of wealth." Given an ethically acceptable initial assignment of wealth, rules based on economic efficiency may have some claim to be considered fair. On the critical issue of distributional equity, however, Posner apparently believes that economics …

Are People Probabilistically Challenged?, Alex Stein

Michigan Law Review

Daniel Kahneman's recent book, Thinking, Fast and Slow, is a must-read for any scholar or policymaker interested in behavioral economics. Behavioral economics is a young, but already well-established, discipline that pervasively affects law and legal theory. Kahneman, a 2002 Nobel Laureate, is the discipline's founding father. His pioneering work with Amos Tversky and others challenges the core economic concept of expected utility, which serves to determine the value of people's prospects. Under mainstream economic theory, the value of a person's prospect equals the prospect's utility upon materialization (U) multiplied by the probability of the prospect materializing (P). When the prospect …

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

All 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

All 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 …

Tribes As Essential Partners In Achieving Sustainable Governance, Prof. Elizabeth Burleson

Prof. Elizabeth Burleson

Indigenous peoples have modeled sustainable development around the world. Incentivizing the innovation and instillation of wind, solar, and other renewable energy sources can come in the form of public funding, including renewable portfolio standards, feed in tariffs and green tag programs. This article analyzes ways in which tribal communities are helping to expand cooperative good governance.

Should We All Be Welfare Economists?, Richard H. Fallon Jr.

Michigan Law Review

On what normative foundation should the edifice of law and public policy be built? What are proper grounds for claims of individual right, and how, generally, do those grounds relate to considerations of individual well-being and social welfare? In this Essay, I argue that individual well-being and a related concept of social welfare should be important considerations in the design of legal rules, but not the exclusive ones. When the notion of well-being receives substantive content, the most plausible and attractive definitions all allow a distinction between what will best promote a person's well-being and what that person might rationally …

"Externalities And Other Parasites." Review Of The Strategic Constitution, By R. D. Cooter, And Constitutional Democracy, By D. C. Mueller, Donald J. Herzog

Reviews

I shall argue that despite the occasional and charmingly belligerent pose struck by some economists of offering a superior alternative to conventional moral and political theory, economics is covertly parasitic on that theory. I begin in Part I by describing some of the core features of economic analysis and by disclosing my own sentiments about that analysis. The description will be terse, the disclosure partial. My aim is to identify, but certainly not pretend to resolve, some thorny methodological issues that surface in these two books. As for the disclosure, well, even if full disclosure were possible, which I doubt, …

Analyze This: A Law And Economics Agenda For The Patent System, Rebecca S. Eisenberg

Articles

Legal scholars and economists might enhance the value and impact of their work by making more effective use of each other's knowledge and capabilities. Legal scholars can offer a more nuanced understanding of the legal rules that underlie the patent system and the doctrinal levers that might be manipulated in furtherance of public policy goals. Economists bring to bear a set of analytical and methodological tools that could shed considerable light on what these doctrinal levers are doing and which of them we ought to be manipulating. Together, we have a better chance of asking the right questions and thinking …
