We examine the effects of a “bubble” in the foreign exchange market, defined as an exogenous process that temporarily shifts the exchange rate away from the value implied by fundamentals. The bubble process is analogous to Bernanke and Gertler's (1999) specification of an asset price bubble....

This paper reports an investigation of the effects of additive and multiplicative uncertainty upon the stabilization properties of a simple base money rule for monetary policy. Using a five-equation empirical model of the United Kingdom, it is shown that changes in the extent of additive...

This paper analyses the welfare performance of a set of five alternative interest rate rules in an open economy stochastic dynamic general equilibrium model with nominal rigidities. A rule with a lagged interest rate term, high feedback on inflation and low feedback on output is found to yield...

This paper examines the performance of simple monetary policy rules in a two country open economy model under both cooperative and non cooperative settings. In particular, it examines the extent to which simple policy rules with external variables and simple policy rules under policy...

We discuss the Taylor rule near low inflation and interest rates. Using an additional option like term in the loss function, our approach extends the simple Taylor rule to one with an asymmetric response near very low inflation rates. Once calibrated, this payoff profile gives an exact, and...

This paper estimates a DSGE model with learning to reexamine the evidence on time variation in post-war U.S. monetary policy. Several papers document a regime switch, by showing that policy changed from 'passive' and destabilizing in the pre-1979 period to 'active' and stabilizing in the...

In a small open economy model with traded and non-traded goods this paper characterizes conditions under which interest rate rules induce aggregate instability by generating multiple equilibria. These conditions depend not only on how aggressively the rule responds to inflation, but also on the...

Many researchers have found that the lagged interest rate enters estimated monetary policy rules with overwhelming significance. However, a recent paper by Rudebusch (2002) argues that the lagged interest rate is not a fundamental component of the U.S. policy rule, and that its significance...

The nature of monetary policy during the 1970s is evaluated through the lens of a forward-looking Taylor rule based on perceptions regarding the outlook for inflation and unemployment at the time policy decisions were made. The evidence suggests that policy during the 1970s was essentially...

In this article, we study the optimal simple monetary policy rules under the Zero Lower Bound using DSGE model. The model economy is open and highly dependent on the terms of trade. Economic dynamics is the result of a terms of trade shock and an external interest rate shock. Using the impulse...
