Optimal monetary policy analysis can be viewed as a constrained optimization problem: the policymaker chooses a competitive equilibrium allocation that maximizes social welfare among the set of all feasible competitive equilibrium allocations. Part of the solution to this problem is a monetary...

This paper analyzes the effects of inflation variability on economic growth in a model where money is introduced via a cash-in-advance constraint. In this setting, we find that inflation adversely affects long-run growth, even when the cash-in-advance constraint applies only to consumption. At...

The celebrated monetarist arithmetic argument of Sargent and Wallace implies outcomes that may be large and unpleasant. But a dynamic stochastic model calibrated to the U.S. economy reveals the quantitative effect of monetarist arithmetic to be small. Monetary policies that react to the level of...

Using a segmented market model that includes state-dependent asset market decisions along with access to credit, we analyze the impact that transactions credit has on interest rates and prices. We find that the availability of credit substantially changes the dynamics in the model, allowing...
