This paper examines the uniqueness and learnability of rational expectations equilibrium when the policy rate is occasionally pegged at the zero lower bound (ZLB). We consider a model that features recurring, transient ZLB regimes and compare various interest rate rules which respond to...

We show that interest rate rules that feed back on the growth rates of target variables (such as output or asset prices) may induce recessions in the presence of a zero lower bound, through purely self-fulfilling dynamics. This pathology is illustrated in a small New Keynesian model with...

We evaluate and compare alternative monetary policy rules, namely average inflation targeting, price level targeting, and traditional inflation targeting rules, in a standard New Keynesian model that features recurring, transient zero lower bound regimes. We use determinacy and expectational...

In this paper, I evaluate the performance deterioration that occurs when the central bank employs an optimal targeting rule that is based on incorrect parameter values. I focus on two parameters - the degree of inflation inertia and the degree of price stickiness. I explicitly account for the...

In a standard New Keynesian model, a myopic central bank concerned with stabilizing inflation and changes in the output gap will implement a policy under discretion that replicates the optimal, timeless perspective, precommitment policy. By stabilizing output gap changes, the central bank...

This paper investigates the circumstances under which a central bank is more or less likely to deviate from the optimal monetary policy rule. The research questions is addressed in a simple New Keynesian dynamic stochastic general equilibrium (DSGE) model in which monetary policy deviations...

We study monetary policy in a New Keynesian model with a variable credit spread and scope for central bank asset purchases to matter. A novel financial and labor market interaction generates an endogenous cost-push channel in the Phillips curve and a credit wedge in the IS curve. The "divine...

This paper estimates a DSGE model with learning to reexamine the evidence on time variation in post-war U.S. monetary policy. Several papers document a regime switch, by showing that policy changed from 'passive' and destabilizing in the pre-1979 period to 'active' and stabilizing in the...
