Axel Leijonhufvud has made a unique contribution to the development of macroeconomic theory. This volume draws together his insightful essays dealing with the extremes of economic instability: great depressions, high inflation and the transition from socialism to a market economy. In several of the papers, Leijonhufvud brings a neo-institutionalist perspective to the problems of coordination in economic systems. The papers within Macroeconomic Instability and Coordination some of them already considered classics, deal with the questions that dominated Leijonhufvud's interest throughout his career as an economist: what are the limits to an economy's capacity to coordinate the activities of its members? How does the behavior of the system change under extreme conditions? In what ways does its performance depend upon the institutions that govern the market process? This book presents in one volume several of Axel Leijonhufvud's most important contributions to macroeconomic theory and monetary economics. It will be invaluable to monetary and financial economists as well as to historians of economic thought.
