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 …

Marginalizing Risk, Steven L. Schwarcz

Faculty Scholarship

A major focus of finance is reducing risk on investments, a goal commonly achieved by dispersing the risk among numerous investors. Sometimes, however, risk dispersion can cause investors to underestimate and under-protect against risk. Risk can even be so widely dispersed that rational investors individually lack the incentive to monitor it. This Article examines the market failures resulting from risk dispersion and analyzes when government regulation may be necessary or appropriate to limit these market failures. The Article also examines how such regulation should be designed,including the extent to which it should limit risk dispersion in the first instance.

Fear Assessment: Cost-Benefit Analysis And The Pricing Of Fear And Anxiety, Matthew D. Adler

Faculty Scholarship

Risk assessment is now a common feature of regulatory practice, but fear assessment is not. In particular, environmental, health and safety agencies such as EPA, FDA, OSHA, NHTSA, and CPSC, commonly count death, illness and injury as costs for purposes of cost-benefit analysis, but almost never incorporate fear, anxiety or other welfare-reducing mental states into the analysis. This is puzzling, since fear and anxiety are welfare setbacks, and since the very hazards regulated by these agencies - air or water pollutants, toxic waste dumps, food additives and contaminants, workplace toxins and safety threats, automobiles, dangerous consumer products, radiation, and so …
