In the first Chapter of this dissertation,I develop a novel dynamic general equilibrium model of banking panics (multiple equilibria) and I analyze the effects of monetary injections during a financial crisis. In the second Chapter,I provide an Irrelevance Proposition that identifies the paths of money supply that are consistent with zero nominal interest rates in a large class of monetary models,with implications for monetary policy at the zero lower bound and for the analysis of the Friedman rule. The last Chapter (joint with Balazs Szentes) derives a utility representation of the evolutionary optimal behavior when a population faces choices over lotteries which determine the number of offspring and involve both idiosyncratic and aggregate risks.
