A fundamental legal problem is whether property rights should be protected by property rules or by liability rules. In this Article, we provide a systematic economic analysis of the choice between property and liability rules. We answer a basic question: why is it that liability rules are...

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...

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...

This is a survey of the field of economic analysis of law, focusing on the work of economists. The survey covers the three central areas of civil law liability for accidents (tort law), property law, and contracts as well as the litigation process and public enforcement of law.

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

Should legal rules be chosen only on the basis of their efficiency or also on the basis of their distributional effects? This article demonstrates that redistribution accomplished through legal rules is systematically less efficient than redistribution accomplished through the income tax system...

Assessment of damages is a principle issue in litigation and, in light of this, we consider the social justification for, and the private benefits of, accurate measurement of harm. Greater accuracy induces parties to exercise levels of precaution that better reflect the magnitude of the harm...

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...
