Postwar business cycles in Japan: A quest for the right explanation

Abstract

This paper explores the nature of postwar business cycles in Japan. Our basic strategy is to study different production behaviors of various manufacturing industries over business cycles. We are particularly interested in the problems of whether only monetary shocks are important and, if not, what kind of real shocks are important. We conclude that purely monetary theory is inadequate, and that construction activities were major causes of aggregate fluctuations in the pre-first oil shock period of rapid growth. We also present some evidence suggesting that real business cycle theory is implausible.
