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...

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...

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...

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 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...

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 investigate how increases in publication delays have affected the life-cycle of publications of recent Ph.D. graduates in economics. We construct a panel dataset of 14,271 individuals who were awarded Ph.D.s between 1986 and 2000 in US and Canadian economics departments. For this population...

Using a newly created microeconomic archive of U.S. imports at the tariff-line level for 1930-33, we construct industry-level tariff wedges incorporating the input-output structure of U.S. economy and the heterogenous role of imports across sectors of the economy. We use these wedges to show...

We provide three sets of variance decompositions on microeconomic international relative price data. The first shows that the overall distribution of absolute deviations from the Law of One Price (LOP) is dominated by cross-sectional variation in long-term averages, not by time-series variation...

We use a unique panel of retail prices spanning 123 cities in 79 countries from 1990 to 2005, to uncover six novel properties of long-run international price dispersion. First, at the PPP level, virtually all (91.6%) of price dispersion is attributed to service-sector wages, consistent with a...
