In this paper we calculate robustly optimal monetary policy rules for several variants of a simple optimizing model of the monetary transmission mechanism with sticky prices and/or wages. We discuss representations of optimal policy both in terms of interest-rate feedback rules that generalize...

This paper proposes a general method for deriving an optimal monetary policy rule in the case of a dynamic linear rational-expectations model and a quadratic objective function for policy. A commitment to a rule of the type proposed results in a determinate equilibrium in which the responses to...

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 makes changes in monetary policy rules (or regimes) endogenous. Changes are triggered when certain endogenous variables cross specified thresholds. Rational expectations equilibria are examined in three models of threshold switching to illustrate that (i) expectations formation...

This paper examines the choice of a monetary-policy rule in a simple macroeconomic model. In a closed economy, the optimal policy is a output and inflation. In an open economy, the optimal rule changes in two ways. First, the policy instrument is a Conditions Index the exchange rate. Second, on...

This paper derives the optimal monetary-policy rule in a simple model with anchored inflation expectations and an effective lower bound (ELB) on interest rates, assuming a long-run inflation goal of 2%. With fully anchored expectations, the optimal policy is a version of average inflation...

This paper investigates the performance, in several small-scale models of the Japanese economy, of an operational monetary policy rule related to ones previously considered for the United States. The rule dictates settings of the monetary base that are designed to produce values of nominal GNP...

The paper discusses how current inflation targeting should be modeled, and argues that it is better represented as a commitment to a targeting rule (a rule specifying operational objectives for monetary policy or a condition for the target variables), than as a commitment to a simple instrument...

We explore the link between an interest rate rule for monetary policy and the behavior of the real exchange rate. The interest rate rule, in conjunction with some standard assumptions, implies that the deviation of the real exchange rate from its steady state depends on the present value of a...
