Yes. Using the workhorse Smets and Wouters (2007) model of the U.S. economy, we find that the role of the output gap should be equal to or even more important than that of inflation when designing a simple loss function to represenst household welfare. Moreover, we document that a loss function...

Tobin's proposition that inflation "greases" the wheels of the labor market is studied using a simple dynamic stochastic general equilibrium model with asymmetric wage adjustment costs. The simulated method of moments is used to estimate the nonlinear model based on its second-order...

It is now widely understood how to obtain first-order accurate approximations to the solution to a dynamic, stochastic general equilibrium model (DSGE model). Such solutions are fairly easy to construct and useful for a wide variety of purposes. They are likely to be accurate enough to be a...

Several papers on international business cycles have documented spurious welfare reversals, in that incomplete market economies can produce higher welfare than the complete market economy. This paper demonstrates how conventional linearization, as used in King, Plosser, and Rebelo (1988), can...

This article addresses past findings of a change in the sign of the price–output correlation in the pre– and post–World War II eras. This “paradox” can be resolved by taking into account the changing direction of price movements, deflation to inflation, during the two time periods....

This paper investigates the accuracy of the log-linear approximation method in welfare calculations, especially in measuring welfare gains of international risk sharing. We derive closed-form solutions for a two-country complete market economy using log-linearization and a nonlinear solution...
