| Summary: | This dissertation consists of three chapters related to questions in monetary economics and financial stability. In the first chapter I develop a simple model of financial crises in which the key externalities are overinvestment ex ante and asset price deflation during the crisis. Constrained efficiency can be achieved through a capital tax before the crisis and through a subsidy on asset purchases during the crisis. In the second chapter I study the interaction of macropudential and monetary policy. I develop a New Keynesian DSGE model in which banks can fund their risky investment activities either with non-state-contingent debt or with state-contingent outside equity. In the third chapter, I revisit the effects of monetary policy shocks in the context of a time-varying coefficients VAR model. Conditional on a recursive identification scheme the effects of monetary policy shocks on output and prices have become weaker from around 1980 to 2010. |
