This paper estimates simple regime-switching rules for monetary policy and tax policy over the post-war period in the United States and imposes the estimated policy process on a standard dynamic stochastic general equilibrium model with nominal rigidities. The estimated joint policy process...

We examine optimal policy in an open-economy model with uncertainty and learning, where monetary policy actions affect the economy through the real exchange rate channel. Our results show that the degree of caution or activism in optimal policy depends on whether central banks are in coordinated...

We study how well a New Keynesian business cycle model can explain the observed behavior of nominal interest rates. We focus on two puzzles raised in previous literature. First, Donaldson, Johnsen, and Mehra (1990) show that while in the U.S. nominal term structure the interest rates are...

We analyze the microfoundations of the Phillips curve, a key relationship in general macroeconomics and models of monetary policy in particular. The form in current widespread use includes both forward looking expected inflation and lagged inflation. The presence of lagged inflation is necessary...

In this paper we analyse the monetary impact of alternative fiscal policy rules using the debt and deficit, both mentioned as measures of fiscal policy performance in the Stability and Growth Pact (SGP). We use a New Keynesian model, with distortionary taxation and an appropriately defined...

I introduce a method to transform a T-map when agents form expectations using a misspecified learning mechanism inconsistent with a structural equation of a multivariate economic model. By transforming the perceived law of motion (PLM) into a the form of a Seemingly Unrelated Regression (SUR)...

Policymaking at the Bank of England has provided detailed information on both the decisions of individual members of the Monetary Policy Committee. We consider this decision making process in the context of a model in which inflation forecast targeting is used but there is heterogeneity among...
