At the aggregate level, the evidence that deviations from purchasing power parity (PPP) are too persistent to be explained solely by nominal rigidities has long been a puzzle (Rogoff, 1996). Another puzzle from the micro price evidence of the law of one price (LOP), which is the basic building...

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...

We examine the role of nominal price rigidities in explaining the deviations from the Law of One Price (LOP) across cities in Japan. Focusing on intra-national relative prices isolates the border effect and thus enables us to extract the pure effect of sticky prices. A two-city model with...

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...

Using micro price data across US cities, we provide evidence that both the volatility and persistence of deviations from the law of one price (LOP) are positively correlated with the distance between cities. A standard, two-city, equilibrium model with time-varying technology under homogeneous...

The beginning of the twentieth century provides a unique opportunity to explore the interaction of rapid technological progress and trade barriers in shaping the worldwide diffusion of a new, highly traded good: the automobile. We scrape historical data on the quantity and value of passenger...

State and local governments throughout the United States attempted to mitigate the spread of Covid-19 using stay-at-home orders to limit social interactions and mobility. We study the economic impact of these orders and their optimal implementation in a fiscal union. Using an event study...

The national terms of trade, defined as the ratio of an export price index to an import price index has been extensively studied empirically. In this paper we construct an alternative measure, which we call the consumption terms of trade. This measure recognizes the fact that consumers and firms...

We develop a model of cities each inhabited by two agents, one specializing in manufacturing, the other in 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 micro-prices...
