Quantitative analysis on competition and productivity (in Japanese)


  • Makoto Funakoshi
  • Kazuyuki Motohashi


In this research, we estimated the Cobb-Douglas production function of a company, and analyzed competitive index, such as HHI, that affect the growth of total factor productivity. In the analysis of the system generalized method of moments, which solves the endogenous problem of explaining variables, market competition, which is represented by HHI raised TFP of firms in Japan. We believe that this empirical analysis can greatly contribute to improving the current Japanese competition policy.
