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...

A Keynesian idea of considerable historical importance is that, in the presence of a liquidity trap, a competitive economy may lack--despite price flexibility--automatic market mechanisms that tend to eliminate excess supplies of labor. The standard classical counterargument, which relies upon...

This paper considers whether 'liquidity trap' issues have important bearing on the desirability of inflation targeting as a strategy for monetary policy. From a theoretical perspective, it has been suggested that 'expectation trap' and 'indeterminacy' dangers are created by variants of inflation...

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...

To consider the prospects, looking 20-30 years into the future, for monetary policymaking in accordance with policy rules, one must evaluate their present importance. That requires some definition of what constitutes rule-based monetary policy in practice, since no actual central bank will ever...

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...

This paper presents a model comparing the optimal degree of asset class diversification abroad by a central bank and a sovereign wealth fund. We show that if the central bank manages its foreign asset holdings in order to meet balance of payments needs, particularly in reducing the probability...

We use the limited participation model of money as a laboratory for studying the operating characteristics of Taylor rules for setting the rate of interest. Rules are evaluated according to their ability to protect the economy from bad outcomes such as the burst of inflation observed in the...

In the wake of the 1997-98 financial crises, interest rates in Asia were raised immediately, and then reduced sharply. We describe an environment in which this is the optimal monetary policy. The optimality of the immediate rise in the interest rate is an example of the theory of the second...

This paper develops an analytical framework for the analysis of targeting rules for monetary policy. We derive the optimal money supply rule and analyze the implications of other monetary rules including rules that target nominal GNP, the price level, the monetary growth rate and the...
