一般注記* Revised: Has the Competition in the Japanese Banking Sector Improved ? [02-09, 2002]
This paper investigates whether competition in the Japanese banking sector has improved inthe last quarter of the 20th century. By estimating the first order condition of profitmaximization, together with the cost function and the inverse demand function, we foundthat competition had improved, especially in the 1970s and in the first half of the 1980s.The results fail to reject a Cournot oligopoly for city banks for most of the period, whilethey do reject it for regional banks for the overall period. This suggests that competitionamong city banks was stronger than that among regional banks.
