Can the Financial Restraint Hypothesis Explain Japans Postwar Experience?
Author InfoHanazaki, Masaharu Horiuchi, Akiyoshi Abstract While the Japanese banking sector seems to have disciplined borrower firms for inefficient management in the high growth era, its fragility was revealed by the serious non-performing loans since the early 1990s. According to ‘the financial restraint hypothesis’ advocated by Hellmann, Murdock and Stiglitz (1996), the comprehensive competition-restricting regulation was effective in motivating banks to prudently monitor their client firms by giving the banks excess profit opportunities. The financial deregulation started at the beginning of the 1980s undermined banks’ profitability and induced the banks to shirk monitoring. Thus, according to the financial restraint hypothesis, the Japan’s bank crisis in the 1990s was a consequence of the financial deregulation in the 1980s. This paper criticizes the financial restraint hypothesis, and proposes the alternative hypothesis that the banking sector was potentially fragile even before
