In analyses of "liquidity trap" problems associated with the zero lower bound (ZLB) on nominal interest rates, it is important to emphasize the difference between policy rule changes, intended to help escape an existing ZLB situation, and maintained policy rules designed so as to avoid ZLB...

In standard approaches to monetary policy, interest rate rules often lead to indeterminacy. Sophisticated policies, which depend on the history of private actions and can differ on and off the equilibrium path, can eliminate indeterminacy and uniquely implement any desired competitive...

This paper reviews the distinction between the timeless perspective and discretionary modes of monetary policymaking, the former representing rule-based policy as recently formalized by Woodford (1999b). In models with forward-looking expectations, this distinction is greater than in the models...

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

We estimate a forward-looking monetary policy reaction function for the postwar US economy, pre- and post-October 1979. Our results point to substantial differences in the estimated rule across periods. In particular, interest rate policy in the Volcker-Greenspan period appears to have been much...

This paper evaluates alternative rules by which the Fed may set interest rates using the small model of the U.S. economy estimated in Rotemberg and Woodford (1997). Our main substantive finding is that low and stable inflation together with stable interest rates can be achieved by letting the...

A growing empirical and theoretical literature argues in favor of specifying monetary policy in the form of Taylor-type interest rate feedback rules. That is, rules whereby the nominal interest rate is set as an increasing function of inflation with a slope greater than one around an intended...

The purpose of the paper is to survey and discuss inflation targeting in the context of monetary policy rules. The paper provides a general conceptual discussion of monetary policy rules, attempts to clarify the essential characteristics of inflation targeting, compares inflation targeting to...

The paper discusses several issues related to how monetary policy should be conducted in an era of price stability. Low inflation (with base drift in the price level) and price-level stability (without such base drift) are compared, and a suitable loss function (corresponding to flexible...
