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 reviews and interprets some of the key policy implications that flow from a class of DSGE models for optimal monetary policy in the open economy. The framework suggests that good macroeconomic outcomes in open economies are possible by focusing inflation targeting that is implemented...

This paper evaluates alternative rules by which the Fed may set interest rates using the small model of the U.S. economy estimated in Rotemberg and Woodford (1997). Our main substantive finding is that low and stable inflation together with stable interest rates can be achieved by letting the...

This paper was prepared as a Keynote Address for the ESRC Conference on the Future of Macroeconomics held at the Bank of England Conference Center on April 14, 2000. It uses the empirical framework for formulating and estimating forward looking monetary policy rules developed in Clarida, Gali,...

While the degree of policy inertia in central banks' reaction functions is a central ingredient in theoretical and empirical monetary economics, the source of the observed policy inertia in the U.S. is controversial, with tests of competing hypotheses such as interest-smoothing and...

Financial systems are inherently fragile because of the very function which makes them valuable: liquidity transformation. Regulatory reforms can strengthen the financial system and decrease the risk of liquidity crises, but they cannot eliminate it completely. This leaves monetary policy with a...

This paper studies the small estimated effects of monetary policy shocks from standard VAR's versus the large effects from the Romer and Romer (2004) approach. The differences are driven by three factors: the different contractionary impetus, the period of reserves targeting and lag length...

Farmer, Waggoner, and Zha (2009) show that a new Keynesian model with a regime-switching monetary policy rule can support multiple solutions that depend only on the fundamental shocks in the model. Their note appears to find solutions in regions of the parameter space where there should be no...

The new-Keynesian, Taylor-rule theory of inflation determination relies on explosive dynamics. By raising interest rates in response to inflation, the Fed induces ever-larger inflation or deflation, unless inflation jumps to one particular value on each date. However, economics does not rule out...

Recent mainstream monetary policy analysis focuses on rational expectation solutions that are uniquely stable. A number of recent studies have examined the question of whether typical New Keynesian (NK) models, with policy rules that satisfy the Taylor principle, also exhibit solutions with...
