In a stylized DSGE model with an energy sector, the optimal policy response to an adverse energy supply shock implies a rise in core inflation, a larger rise in headline inflation, and a decline in wage inflation. The optimal policy is well-approximated by policies that stabilize the output gap,...

Gali and Gertler (1999) are the first to find that the baseline sticky price model fits the U.S. data well. I examine the robustness of their estimates along two dimensions. First, I show that their IV estimates are not robust to an alternative normalization of the moment condition being...

We develop a general equilibrium model of a two-region currency union. There are two types of goods: non-trade goods, and traded goods for which markets are segmented. Monetary policy is set by a central monetary authority and is non-neutral due to nominal price rigidities. Fiscal policy is...

One of the criticisms routinely advanced against models of the business cycle with staggered contracts is their inability to generate inflation persistence. This paper finds that staggered Taylor contracts are, in fact, capable of reproducing the inflation persistence implied by U.S. data....

We provide a tractable model to study monetary policy under discretion. We focus on Markov equilibria. For all parametrizations with an equilibrium inflation rate around 2%, there is a second equilibrium with an inflation rate just above 10%. Thus the model can simultaneously account for the low...

Using a new approach, we reexamine the empirical evidence on the long-term interactions between inflation and real variables. We find, using over 100 years of U.S. data, that in the long run the effect of inflation on investment and output is positive (a "Tobin type effect") and the investment...
