This chapter of the forthcoming Handbook of Law and Economics surveys the theory of the public enforcement of law %u2013 the use of governmental agents (regulators, inspectors, tax auditors, police, prosecutors) to detect and to sanction violators of legal rules. The theoretical core of our...

This paper studies optimal dynamic tax policy under the threat of political reform. A policy will be reformed ex post if a large enough political coalition supports reform; thus, credible policies are those that will continue to attract enough political support in the future. If the only...

The termination of a representative financial firm due to excessive leverage may lead to substantial bankruptcy costs. A government in the tradition of Ramsey (1927) may be inclined to provide transfers to the firm so as to prevent its liquidation and the associated deadweight costs. It is shown...

This paper develops a model of a self-fulfilling credit market freeze and uses it to study alternative governmental responses to such a crisis. We study an economy in which operating firms are interdependent, with their success depending on the ability of other operating firms to obtain...

Many financing choices of US corporations remain puzzling even after accounting for standard determinants such as taxes, bankruptcy costs, and asymmetric information. We propose that managerial beliefs help to explain the remaining variation across and within firms, including variation in debt...

We develop a tax competition framework in which some jurisdictions, called tax havens, are parasitic on the revenues of other countries. The havens use real resources to help companies camouflage their home-country tax avoidance, and countries use resources in an attempt to limit the transfer of...

The transaction costs of defining the property rights to mitigation benefits and costs is a useful framework for such analysis. This approach views international cooperation...
