Temporary versus Permanent Legislation
Lisa Bernstein and Francesco Parisi
Customary law has been the subject of intense debate and the issues arising from the intersection of customs and the law are far from settled. This research review brings together seminal work from scholars in law, economics and history. The first section analyses various perspectives on the history of customary law. Part two focuses on the commercial customary law and includes a number of case studies covering the role and limits of customary systems in a variety of commercial settings. The final section explores the role of custom in international law from a variety of legal and economic perspectives.

This research review examines some of the most important articles on the topic of law and economics. Although the wealth of scholarship and the steady expansion of the field make the task of selecting representative works a challenge, the growth rate underscores the relevance and importance of the economic approach to the theory and practice of law. In this essay, therefore, we offer a survey of this vast interdisciplinary movement, exploring its rapid assimilation of disparate legal subject matters. We cannot hope to cover every major result discovered over the course of several decades in the space available. However, we hope to convey at least a general sense of what law and economics is, how it can inform real-world adjudication, and how it developed over the decades.
