A policy rule can be activist; the distinction between rules and discretion depends on the stage at which optimization calculations enter the policy process. Here a specific monetary rule is proposed, one that sets the monetary base each quarter in a manner designed to keep nominal aggregate...

Several arguments are relevant. (1) In the absence of the zero lower bound (ZLB), the optimal steady-state inflation rate, according to standard reasoning, lies between deflation at the steady-state real interest rate and the Calvo-model value of zero, with calibration indicating a larger weight...

This paper argues, first, that it is inappropriate to presume that central banks will, in the absence of any tangible precommitment technology, inevitably behave in a `discretionary' fashion that implies an inflationary bias. Furthermore, there is no necessary tradeoff between `flexibility and...

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 a recent paper, Canzoneri, Henderson, and Rogoff have shown that it is possible for the monetary authority to peg the nominal interest rate without creating price level indeterminacy in a simplified version of the 1975 Sargent-Wallace model. The present paper begins by reviewing that result,...

This paper reconsiders a result obtained by Sargent and Wallace, namely, that price level indeterminacy obtains in their well-known model if the monetary authorities adopt a policy feedback rule for the interest rate rather than the money stock. Since the Federal Reserve seems often to have used...

This paper reports results of simulation exercises that explore several questions relating to the design of rules for monetary policy. Emphasis is given to issues raised by the concept of rule operationality, i.e., reliance on feasible instrument variables and information sets. Many of the...

This paper explores several issues concerning a possible zero lower bound (ZLB) including its theoretical rationale; the magnitude of effects of low sustained inflation on real interest rates; the validity of analyzing monetary policy in models with no monetary variables; and the dynamic...
