抄録

This article presents a new simple econometric framework for the estimation of individual firms' markup over their marginal cost, taking account of firm heterogeneity, demand-driven cyclical price changes, and the limited availability of firm-level information. The framework is applied to study markup of Japanese firms in manufacturing and wholesale/ retail trade for 1994-2002. The results indicate that, on average, the Japanese markets become more competitive in the 1990s than before even in non-manufacturing industries. We also find sizable heterogeneity and non-negligible pro-cyclicality in the markup of the Japanese firms.
