We compare the dynamics of inflation and bond yields leading up to a sovereign debt crisis in settings where asset markets are frictionless to other settings with financial frictions. As compared to the case with frictionless asset markets, an asset market structure with financial frictions...

We compare the dynamics of in flation and bond yields leading up to a sovereign debt crisis in settings where asset markets are frictionless to other settings with financial fric- tions. As compared to the case with frictionless asset markets, an asset market structure with financial frictions...

We provide two ways to reconcile small values of the intertemporal elasticity of substitution (IES) that range between 0.35 and 0.5 with empirical evidence that the IES is large. This is done using a model in which all agents have identical preferences and the same access to asset markets. We...

We consider a sticky-price model with segmented asset markets, and examine its implications for monetary policy. Our finding is, first, that the response of the money supply growth rate to a money demand shock required to stabilize inflation is not affected by the existence of a liquidity...

We consider an efficiency-wage model with the Calvo-type sticky prices and analyze the optimal monetary policy when the unemployment insurance is not perfect. With imperfect risk sharing, the strict zero-inflation policy is no longer optimal even when the zero-inflation steady-state equilibrium...

In this paper we consider a two-country New Open Economy Macroeconomics model, and analyze the optimal monetary policy when countries cooperate in the face of a "global liquidity trap"--i.e., a situation where the two countries are simultaneously caught in liquidity traps. The notable features...

When individuals' labor and capital income are subject to uninsurable idiosyncratic risks, should capital and labor be taxed, and if so how? In a two period general equilibrium model with production, we derive a decomposition formula of the welfare effects of these taxes into insurance and...

Should capital and labor be taxed, and if so how when individuals' labor and capital income are subject to uninsurable idiosyncratic risks? In a two period general equilibrium model with production, we first show that reducing investment is welfare improving if households are homogeneous enough...
