Under a discretionary regime the monetary authority makes no commitments about future money and prices. Then, if surprise inflation conveys economic benefits and if people form expectations rationally, it turns out that the equilibrium involves high and variable monetary growth and inflation....

Recent experience does not include a "monetarist experiment," as some have argued, but may slightly reinforce preexisting reasons for doubting that the best way of formulating monetarist policy prescriptions is in the form of a constant growth rule for the money stock.A more desirable rule would...

In a discretionary regime the monetary authority can print more money and create more inflation than people expect. But, although these inflation surprises can have some benefits, they cannot arise systematically in equilibrium when people understand the policymaker's incentives and form their...

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 discusses exchange rate rules in their role as macroeconomic instruments. Two quite different approaches are pursued. The traditional view is that exchange rate flexibility is a substitute for money wage flexibility so that managed money and managed exchange rates yield the necessary...

This paper characterizes the properties of various interest-rate rules in a basic forward-looking model. We compare simple Taylor rules and rules that respond to price-level fluctuations (called Wicksellian rules). We argue that by introducing an appropriate amount of history dependence in...

This paper focuses on simple rules for monetary policy which central banks have used in various ways to guide their interest rate decisions. Such rules, which can be evaluated using simulation and optimization techniques, were first derived from research on empirical monetary models with...

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...

Forecast targeting is an innovation in central banking that represents an important step toward more rule-based policymaking, even if it is not an attempt to follow a policy rule of any of the types that have received primary attention in the theoretical literature on optimal monetary policy....
