The Bonn Workshop 1997—Theories of Bounded Rationality, (May 6-10, 1997) was an international meeting of researchers interested in behavioral theories in economics. It was held in honor of Reinhard Selten. One goal of the workshop was to provide a platform for the introduction of new theories improving the understanding for the boundedly rational behavior of economic agents. Another goal was to support the search for links between existing theories of bounded rationality. We restricted the focus to the following topics:

1. (1) Individual Decision Making;

2. (2) Learning and Coordination;

3. (3) Bargaining and Reciprocity;

4. (4) Markets and Economic Institutions.

In order to generate a common basis for discussion, we invited four researchers to give state of the art presentations on each of the four topics. The presentations were general overviews of the corresponding experimental, empirical, and theoretical literature. Each presentation also confronted conflicting approaches and provided an insight into the problems of theory formation. The state of the art contributions were the fulcrum of vigorous discussions and had a major impact on the proceeding of the workshop. We are convinced that these contributions will be of great interest to the broader audience that they can reach through publication.
