 note = {In the present paper, we apply the generalized user-revenue model (GURM) presented by Homma (2009) to Japan’s banking industry and perform an analysis fusing producer theory and industrial organization theory (applied microeconomics) and finance (asset pricing theory). Basically, while basing the approach on the GURM, we derived the generalized user-revenue prices (GURPs) and the extended generalized Lerner indices (EGLIs), organized their theoretical characteristics from an interdisciplinary analytical perspective, applied the GURM to Japanese city banks, and estimated the GURPs and the EGLIs. These efforts provided material for thinking about the necessity of risk-adjustment policies as part of the industrial organization policy in the banking industry. Based on the EGLI estimation results, regarding the components of the EGLIs (in terms of absolute value), the risk-adjustment effects are the largest, followed by the equity capital effects, and the market structure and conduct effects are the smallest. This is the same as the results for the GURPs, so there is pressure to review conventional competition policy, which considers primarily the market structure and conduct effects. It has been pointed out that switching from a competition policy to a risk-adjustment policy is necessary, so specific measures in risk-adjustment policy that have not yet been considered must be taken into account. Furthermore, the injection of public funds dramatically improved (decreased) the risk-adjustment effects of the EGLI for long-term loans and dramatically increased the degree of competition in the long-term loan market., Working Paper, Working Paper, No.271, 2012.6, Faculty of economics, university of toyama},
