These proceedings, from a conference held at the Federal Reserve Bank of St. Louis on October 17-18, 1991, attempted to layout what we currently know about aggregate economic fluctuations. Identifying what we know inevitably reveals what we do not know about such fluctuations as well. From the vantage point of where the conference's participants view our current understanding to be, these proceedings can be seen as suggesting an agenda for further research. The conference was divided into five sections. It began with the formu lation of an empirical definition of the "business cycle" and a recitation of the stylized facts that must be explained by any theory that purports to capture the business cycle's essence. After outlining the historical develop ment and key features of the current "theories" of business cycles, the conference evaluated these theories on the basis of their ability to explain the facts. Included in this evaluation was a discussion of whether (and how) the competing theories could be distinguished empirically. The conference then examined the implications for policy of what is known and not known about business cycles. A panel discussion closed the conference, high lighting important unresolved theoretical and empirical issues that should be taken up in future business cycle research. What Is a Business Cycle? Before gaining a genuine understanding of business cycles, economists must agree and be clear about what they mean when they refer to the cycle."

This collection of essays departs from the conventional economic paradigm wherein individuals or groups choose among various productive activities for mutually beneficial trade. Each essay recognizes that where property rights are not well defined or easily enforced, individuals may forgo productive opportunities and engage in appropriative activities to compete for property, income, rights or privileges. Though the essays differ in their focus, each illustrates the importance of the institutional setting in determining economic activity. The first of the two sets of essays examines the allocation of resources among productive and appropriative activities in an anarchical political environment, without legal or constitutional tradition. Their objective is to understand different facets of the emergence of order and restraint on individual behaviour out of conditions with few or no assumed constraints. The second set focuses on different types of political institutions, illustrating how they shape conflict and economic activity, and how they themselves can be shaped by conflict.
