| Outline of Final Research Achievements |
This study explores theoretical implications of the efficient structure and quiet-life hypotheses on the basis of the generalized user-revenue model constructed by Homma (2009, 2012). From the perspective of the extended generalized-Lerner index (EGLI) on the cost frontier, the following two points are noteworthy: 1) it is not always possible to justify anti-monopoly and anti-concentration policies using support for the quiet-life hypothesis; and 2) new industrial organization policies are required if support for the efficient structure hypothesis is undesirable. Furthermore, where intertemporal regular linkage of single-period EGLIs on the cost frontier exists, the appropriate industrial organization policies must be determined based on a long-term perspective.
