Competition and productivity in Japanese manufacturing industries

"This paper examines the determinants of productivity in Japanese manufacturing industries, looking particularly at the impact of product market competition on productivity. Using a newly available panel data on around ten thousand firms in Japanese manufacturing for the years 1994-2000, I show that competition, as measured by lower level of industrial price-cost margin, enhances productivity growth, controlling for a broad range of industrial and firm-specific characteristics. Moreover, I suggest that market power, as measured by either individual firm's price-cost margin or market share, has negative impact on productivity level of R&D performing firms"--National Bureau of Economic Research web site.
