Volatile and persistent real exchange rates are observed not only in aggregate series but also on the individual good level data. Kehoe and Midrigan (2007) recently showed that, under a standard assumption on nominal price stickiness, empirical frequencies of micro price adjustment cannot...

We propose a simple saving-based measure of the cyclical component in GDP. The measure is motivated by the prediction that the representative consumer changes savings in response to temporary deviations of income from its stochastic trend, while satisfying a present-value budget constraint. To...

In this paper, we argue that differences in the cost structure across sectors play an important role in the decision of firms to adjust their prices. We develop a menu cost model of pricing in which retail firms intermediate trade between producers and consumers. An important facet of our...

Economic research into the causes of business cycles in small open economies is almost always undertaken using a partial equilibrium model. This approach is characterized by two key assumptions. The first is that the world interest rate is unaffected by economic developments in the small open...

The current account in developed countries is highly persistent and volatile in comparison to output growth. The standard intertemporal current account model with rational expectations (RE) fails to account for the observed current account dynamics together with persistent changes in...

The classical dichotomy predicts that all of the time series variance in the aggregate real exchange rate is accounted for by nontraded goods in the CPI basket because traded goods obey the Law of One Price. In stark contrast, Engel (1999) found that traded goods had comparable volatility to the...

International business-cycle models assume that home and foreign goods are poor substitutes. International trade models assume they are close substitutes. This paper constructs a model where this discrepancy is due to frictions in distribution. Imports need to be combined with a local non-traded...

We develop a model of cities each inhabited by two agents, one specializing in manufacturing, the other in retail distribution. The distribution sector represents the physical transformation of all internationally traded goods from the factory gate to the final consumer. Using a panel of...

Using US micro price data at the city level, we provide evidence that both the volatility and the persistence of deviations from the law of one price (LOP) are rising in the distance between US cities. A standard, two-city, stochastic equilibrium model with trade costs can predict the...
