Research with Keynesian-style models has emphasized the importance of the output gap for policies aimed at controlling inflation while declaring monetary aggregates largely irrelevant. Critics, however, have argued that these models need to be modified to account for observed money growth and...

We use a standard quantitative business cycle model with nominal price and wage rigidities to estimate two measures of economic inefficiency in recent U.S. data: the output gap (the gap between the actual and efficient levels of output) and the labor wedge (the wedge between households' marginal...

In view of the increasing use of Dynamic Stochastic General Equilibrium (DSGE) models in the macroeconomic projections and the policy process, this paper examines, both conceptually and empirically, alternative notions of potential output within DSGE models. Furthermore, it provides historical...

This paper analyzes the implications of responding to either the model-based New Keynesian output gap or to its estimates, and in particular, a Hodrick-Prescott filtered output gap or a linearly detrended output gap. Responding to these estimates instead of to the “true” unobserved output...

The recent global financial crisis illustrates that financial frictions are a significant source of volatility in the economy. This paper investigates monetary policy stabilization in an environment where financial frictions are a relevant source of macroeconomic fluctuation. We derive a measure...

This paper studies optimal robust monetary policy when the central bank imperfectly observes potential output and has Knightian uncertainty about the intertemporal elasticity of substitution and the slope of the Phillips curve. The literature on optimal robust monetary policy has focused on...

We estimate the unobserved time-varying natural interest rate (NIR) and potential output for the Indian economy using the Kalman Filter. Estimation is a special challenge in an emerging market because of limited length of data series and ongoing structural change. A key result in the literature...
