In cash-in-advance models, necessary and sufficient conditions for the existence of an equilibrium with zero nominal interest rates and Pareto-optimal allocations restrict only the very long-run, or asymptotic, behavior of the money supply. When these asymptotic conditions are satisfied, they...

This paper develops a method for combining the power of a dynamic, stochastic, general-equilibrium model with the flexibility of a vector autoregressive time-series model to obtain a hybrid that can be taken directly to the data.

In models with heterogeneous agents, issues of distribution and redistribution jump to the fore, raising the question: Which policies-monetary or fiscal-work most effectively in transferring income between groups? From Townsend's turnpike model, two basic results emerge to help answer this...

The monetary transmission mechanism describes how policy-induced changes in the nominal money stock or the short-term nominal interest rate impact real variables such as aggregate output and employment. Specific channels of monetary transmission operate through the effects that monetary policy...

A two-sector real business cycle model, estimated with postwar U.S. data, identifies shocks to the levels and growth rates of total factor productivity in distinct consumption- and investment-goods- producing technologies. This model attributes most of the productivity slowdown of the 1970s to...
