This paper develops a welfare-based model of monetary policy in an open economy. We focus on the extent to which monetary policy should be employed in maintaining the exchange rate. The traditional approach maintains that exchange rate flexibility is desirable in the presence of real...

This paper focuses on the specification and stability of a dynamic, stochastic, general equilibrium model of the American business cycle with sticky prices. Maximum likelihood estimates reveal that the data prefer a version of the model in which adjustment costs apply to the price level but not...

This paper discusses how optimal monetary policy is affected by differences in the combination of shocks an economy experiences and the rigidities it exhibits. Without both nominal rigidities and economic shocks, monetary policy would be irrelevant. Recognizing this, policymakers increasingly...

The paper develops a simple stochastic new open economy macroeconomic model based on sticky nominal wages. Explicit solution of the wage-setting problem under uncertainty allows one to analyze the effects of the monetary regime on welfare, expected output, and the expected terms of trade....

The importance of sticky prices in business cycle fluctuations has been debated for many years. But we argue, based on a large empirical literature from the 1950's and 60's, that it is necessary to distinguish the response of price to an increase in factor prices from its response to an increase...

We use new disaggregated data on consumer prices to determine why there is variability in prices of similar goods across U.S. cities. We address questions similar to those that have arisen in the international context: is this variability purely a result of market segmentation or do sticky...

New Keynesian models of price setting under monopolistic competition involve two kinds of inefficiency: the price level is too high because firms ignore an aggregate demand externality, and when there are costs of changing prices, price stickiness may be an equilibrium response to changes in...

This paper contributes to the empirical literature on price stickiness by documenting a high rate of nominal rigidity among apartment rents in the U.S. between 1974-1981. 29 percent of units had no change in nominal rent from year to year. Nominal rigidity was much higher among units whose...

This paper investigates the behavior of the foreign exchange risk premium in two recent two-country intertemporal-optimizing general equilibrium models with sticky nominal prices: Obstfeld-Rogoff (1998) and Devereux-Engel (1998). The foreign exchange risk premium in any general equilibrium model...

We study the effects of monetary and fiscal policies when both money and government bonds provide liquidity services. Because money is the unit of account, the price of money is the inverse of the price level. If prices are sticky, so is the price of money in terms of goods, and this is one...
