The Effect of Unions on Firm Performance in Japanese Manufacturing

Abstract

Using data on a sample of 979 union and nonunion Japanese manufacturing firms selected from the 1987 issue of the Yearbook of Japanese Unlisted Companies, the author examines the relationship between union status and firm performance in Japan. The findings suggest that Japanese unions in the sample substantially reduced both productivity and profitability, as well as regular wages net of bonuses and fringes. These three union effects were considerably smaller in small and medium-size firms than in large firms, perhaps because many of the small and medium-size firms were subcontractors that were pressed by the firms contracting them to cut costs and increase productivity.
