This paper develops a welfare-based model of monetary policy in an open economy. We focus on the extent to which monetary policy should be employed in maintaining the exchange rate. The traditional approach maintains that exchange rate flexibility is desirable in the presence of real...

We explore how consumption heterogeneity affects the international transmission mechanism of monetary shocks and the choice of optimal monetary policy in an open economy. Incorporating two types of agents (Ricardian versus Keynesian) into a standard open economy macro model, we find that there...

We examine to what extent variants of inflation-forecast targeting can avoid stabilization bias, incorporate history-dependence, and achieve determinancy of equilibrium, so as to reproduce a socially optimal equilibrium. We also evaluate these variants in terms of the transparency of the...

Monetary policy can achieve average inflation equal to a given inflation target and, at best, a good compromise between inflation variability and output-gap variability. Monetary policy cannot completely stabilize either inflation or the output gap. Increased credibility in the form of inflation...

Policy rules that are consistent with inflation targeting are examined in a small macroeconomic model of the US economy. We compare the properties and outcomes of explicit instrument rules' as well as targeting rules.' The latter, which imply implicit instrument rules, may be closer to actual...

Previous analysis of the implementation of inflation targeting is extended to monetary policy responses to different shocks, consequences of model uncertainty, effects of interest rate smoothing and stabilization, a comparison with nominal GDP targeting, and implications of forward-looking...

Inflation targeting is shown to imply inflation forecast targeting: the central bank's inflation forecast becomes an explicit intermediate target. Inflation forecast targeting simplifies both implementation and monitoring of monetary policy. The weight on output stabilization determines how...

Price level targeting (without base drift) and inflation targeting (with base drift) are compared under commitment and discretion, with persistence in unemployment. Price level targeting is often said to imply more short-run inflation variability and thereby more employment variability than...

The dangers of high capital flow volatility and sudden stops have led economists to promote the use of capital controls as an addition to monetary policy in emerging market economies. This paper studies the benefits of capital controls and monetary policy in an open economy with financial...

The 'International Policy Trilemma' refers to the constraint on independent monetary policy that is forced on a country which remains open to international financial markets and simultaneously pursues an exchange rate target. This paper shows that, in a global economy with open financial...
