This is a survey of economic analysis of law, that is, of the emerging field under which the standard tools of microeconomics are employed to identify the effects of legal rules and their social desirability. Five basic subject areas are covered. The first is legal liability for harm. Here we...

Much legal advice is provided after individuals have committed acts -- when they come before a tribunal -- rather than at the time they decide how to act. This paper considers the effects and social desirability of such legal advice. It is emphasized that 1egl advice tends to reduce expected...

The traditional view of economists has been that corrective taxes are superior to direct" regulation of harmful externalities when the state's information about control costs is incomplete. " In recent years, however, many economists seem to have adopted the view that either corrective" taxes or...

Many legal rules, notably rules of procedure and evidence, are concerned with achieving accuracy in the outcome of adjudication. In this article, we study accuracy in the conventional model of law enforcement. We consider why reducing error in determining liability is socially valuable and how...

Self-reporting--the reporting by parties of their own behavior to an enforcement authority--is a commonly observed aspect of law enforcement, such as in the context of environmental and safety regulation. The authors add self-reporting to the model of the control of harmful externalities through...

The public at large, many policymakers, and a number of economists hold views of social welfare that are non-welfarist. That is, they attach some importance to factors other than the effects of policies on individuals' utilities. We show, however, that any non-welfarist method of policy...

In Fairness versus Welfare, we advance the thesis that social policies should be assessed based entirely on their effects on individuals' well-being. This thesis implies that no independent weight should be accorded to notions of fairness (other than many purely distributive notions). We support...

We examine how moral sanctions and rewards, notably the moral sentiments involving feelings of guilt and virtue, would be employed to govern individuals' behavior if the objective were to maximize social welfare. In our model, we analyze how the optimal use of guilt and virtue is influenced by...
