Title: Monetary Policy Issues Arising From Bank Competition
Author: Severe, Sean P.
Abstract: The banking sector has been extensively analyzed in economics. On the microeconomic side, research has advanced our understanding of banks and the inverse relationship between market power and bank production. The macroeconomic side of research has focused on the transmission of monetary policy, and it is understood that the financial system, including banks, plays an integral role in transmitting monetary policy decisions to economic variables such as investment, consumption, and GDP. There is limited understanding, however, about how market power and bank concentration affects the transmission of monetary policy. The main focus of this dissertation is to address this gap in the literature and is achieved by three contributions. First, I develop a theory of banking behavior that accounts for competition and monetary policy. I empirically test the theory and show that banking concentration dampens the impact of monetary policy on lending activity in the short-run. My second contribution involves building a theoretical model with these short-run lending effects incorporated into an endogenous growth model that allows agents, banks, and the central bank to interact. This model shows how short-run lending is tied to growth. Again, monetary policy is less effective in markets with higher concentration. The last contribution is made by empirically testing the second contribution. The empirical findings are consistent with both the first and second contributions; banking markets with less competition adversely affect growth and also diminish the long-run impact of monetary policy.
