Volatile and persistent real exchange rates are observed not only in aggregate series but also in 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 introduce the real exchange rate volatility curve as a useful device to understand the role of price stickiness in accounting for deviations from the Law of One Price at the sector level. In the presence of both nominal and real shocks, the theory predicts that the real exchange rate...

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