KINAI Taku; OSADA Takeshi
Number:33, First page:39, Last page:48, Mar. 2019, [Reviewed]
This paper is the first empirical research on the determinants of the capital structure of Japanese banks, using Japanese banks' financial data for two decades from 2000 to 2017 and adding new evidence to previous literature on the banks' capital structure. Previous researches show that the determinants of capital structure are different among countries or continents. We show that determinants vary and change in accordance with differences in business models among banks even within one country. By focusing on different business models between four sub-samples, "International banks before the Global Financial Crisis," "Domestic banks before the GFC," "International banks after the GFC," and "Domestic banks after the GFC", we analyze whether the determinants of capital structure differ among these sub-samples. The results are totally different and we find no determinants which can significantly and commonly explain all four sub-samples.

Focusing on three different banks' behaviors, or variables, that capture the efficiency of banks ("Average age of employees of banks", "Personal network of board members", "Banks' Holding Behavior of excess reserves"), we conducted three different empirical studies which examine the effects of capital injection policies on the efficiency of banks. We show that capital injections triggered labor force rejuvenation and personal network disruption. Although we haven't drown a clear conclusion from our results in terms of the impacts on banks' efficiency, we could provide some evidence to evaluate multifaceted capital injection policies.
In addition to these three researches, in the 4th research, we show that the spreading of new payment methods, or money, and the resulting competition between moneys due to the progress of Fintech may have a negative influence on the financial system.
