We show that a so-called expectations-based optimal monetary policy rule has desirable properties in a standard New Keynesian model augmented with a cost channel and inflation rate expectations that are partly backward-looking. In particular, optimal monetary policy under commitment is...

We argue that it is not necessary for the central bank to react to the exchange rate to have a desirable outcome in the economy. Indeed, when the Taylor rule includes contemporane-ous data on the variables in the rule, the central bank can disregard from the exchange rate as long as there is...

We consider standard monetary-policy rules with inflation-rate targets and interest-rate or money-growth instruments using a flexible-price, perfect foresight model. There is always a locally-unique target equilibrium. There are also below-target equilibria (BTE) with inflation always below...

During the Great Recession, despite the large fall in output, inflation did not fall much. This is known as the missing deflation puzzle. In this paper, we develop and estimate a New Keynesian Dynamic Stochastic General Equilibrium model to provide an explanation for the puzzle. The new model...

We use a simple New Keynesian model, with firm specific capital, non-zero steady-state inflation, long-run risks and Epstein-Zin preferences to study the volatility implications of a monetary policy shock. An unexpected increases in the policy rate by 150 basis points causes output and inflation...

This paper conducts a structural analysis of inflation persistence in the United Kingdom between 1965-2009. I allow for the possibility of shifts in the U.K. economy by estimating open-economy dynamic stochastic general equilibrium models in which parameters of a Taylor-type monetary policy...

We consider an incomplete-markets economy with capital accumulation and endogenous labor supply. Individuals face countercyclical idiosyncratic labor and asset risk. We derive conditions under which the aggregate allocations and price system can be found by solving a representative agent...
