This paper reconsiders the welfare costs of inflation and the welfare gains from financial intermediation in a heterogeneous-agent economy where money is held as a store of value (as in Bewley, 1980). Because of heterogeneous liquidity demand, transitory lump-sum money injections can have...

This paper studies conditions under which demand-side shocks can generate realistic business cycles in RBC models. Although highly persistent demand shocks are necessary for generating procyclical investment, variable capacity utilization and habit formation can reduce the required degree of...

In this paper we show that the highly persistent inflation dynamics and its lead-lag relationship with output can be explained by a standard flexible price RBC model augmented with endogenous monetary policy. Endogenous monetary policy acting upon the illusion that price is sticky and money is...

Price rigidity is the key mechanism for propagating business cycles in traditional Keynesian theory. Yet the New Keynesian literature has failed to show that sticky prices by itself can effectively propagate business cycles in general equilibrium. This situation may be a direct consequence of...

This paper constructs an endogenous growth model driven by self-fulfilling expectation shocks to explain the stylized fact that the average growth rate of GDP is related negatively to volatility and positively to capacity utilization. The implied welfare gain from further stabilizing the U.S....
