We analyze a model in which firms are able to acquire information about product risks and may or may not be required to disclose this information. We initially study the effect of disclosure rules assuming that firms are not liable for the harm caused by their products. Although mandatory...

This article surveys the theory of the public enforcement of law--the use of public agents (inspectors, tax auditors, police prosecutors) to detect and to sanction violators of legal rules. We first present the basic elements of the theory, focusing on the probability of imposition of sanctions,...

The private and the social functions of contracts and of contract law are examined in this entry. In section 1, on the basic theory of contracts, the topics considered include contract formation, why contract enforcement is valuable, the incompleteness of contracts, the interpretation of...

The general reasons are (a) that interpretation may improve on otherwise imperfect contracts; and (b)...

Most legal academics and policymakers believe that notions of fairness should be accorded positive weight in evaluating legal policies. We explain, however, that ascribing importance to any notion of fairness (other than one concerned solely with the distribution of income) will sometimes lead...

The public at large, many policymakers, and a number of economists hold views of social welfare that are non-welfarist, which is to say that some importance is attached to factors other than individuals' utilities.

In our 1994 article in this Journal, we demonstrated that legal rules should not be adjusted to disfavor the rich and favor the poor in order to redistribute income, because the income tax and transfer system is a more efficient means of redistribution. In this article, we revisit our argument...

Minimum asset and liability insurance requirements must often be met in order for parties to participate in potentially harmful activities. Such financial responsibility requirements may improve parties' decisions whether to engage in harmful activities and, if so, their efforts to reduce risk....
