This volume is devoted to the hysteresis phenomenon in economic relationships. This topic has received renewed attention in economics especially in the late eigh ties. Since the issue is not settled there is still a growing literature on it. The aim of this volume is to summarize the findings, present new results, and to draw attention to further research. All papers are written for this volume and are not published elsewhere. I am very grateful to all authors and referees without whose prompt and generous help this volume would not appear in the present form. A short summary of each paper is given in section 5 of the overview paper. Konstanz, January 1990 Wolfgang Franz University of Konstanz Contents Hysteresis in Economic Relationships: An Overview W.
