This paper discusses the effect of capital regulation on the risk taking behavior of commercial banks. We first theoretically show that capital regulation works differently in different market structures of banking sectors. In lowly concentrated markets, capital regulation is effective in mitigating risk taking behavior because banks' franchise values are low and banks have incentives to pursue risky strategies in order to increase their franchise values. If franchise values are high, on the other hand, the effect of capital regulation on bank risk taking is ambiguous as banks lack those incentives. We then test the model predictions on a cross-country sample including 421 commercial banks from 61 countries. We find that capital regulation is effective in mitigating risk taking only in markets with a low degree of concentration. The results remain robust after accounting for financial sector development, legal system effciency, and for other country and bank-specific characteristics. Keywords: Banks, market structure, risk shifting, franchise value, capital regulation
ProtoSociology is an interdisciplinary journal which crosses the borders of philosophy, social sciences, and their corresponding disciplines. Each issue concentrates on a specific topic taken from the current discussion to which scientists from different fields contribute the results of their research. ProtoSociology is further a project that examines the nature of mind, language and social systems. In this context theoretical work has been done by investigating such theoretical concepts like interpretation and (social) action, globalization, the global world-system, social evolution, and the sociology of membership. Our purpose is to initiate and enforce basic research on relevant topics from different perspectives and traditions.
