The classical dichotomy predicts that all of the time-series variance in the aggregate real exchange rate is accounted for by non-traded goods in the consumer price index (CPI) basket because traded goods obey the Law of One Price. In stark contrast, Engel (1999) claimed the opposite: that...

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...

In this paper, we argue that differences in the cost structures across sectors play an important role in firms' decisions 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 analysis...

We study the role of distance and time in statistically explaining price dispersion across 32 Swedish towns for 19 commodities from 1732 to 1914. The resulting large number of relative prices (502,689) allows precise estimation of distance and time effects, and their interaction. We find an...

Drawing on recent business cycle research on the Great Depression, we return to an argument we advanced in a 1996 article in the Journal of Monetary Economics—the argument that features of the Hawley-Smoot tariffs could have done more to decrease economic activity than is customarily believed,...

We review research using departures from the law of one price to measure the advent of globalization in Europe and Asia. In an application, we then study the role of distance and time in statistically explaining price dispersion across 32 Swedish towns for 19 commodities from 1732 to 1914. The...

This paper examines the global drivers of inflation in 55 countries over the 1970-2022 period. We estimate a Factor-Augmented Vector Autoregression model for each country and assess the importance of several global (demand, supply, and oil price) and domestic shocks. We report three main...

This paper examines the drivers of fluctuations in global inflation, defined as a common factor across monthly headline consumer price index (CPI) inflation in G7 countries, over the past half-century. We estimate a Factor-Augmented Vector Autoregression model where a wide range of shocks,...

This paper investigates the relationship between the level of inflation and regional price-level convergence utilizing micro-level price data from Turkey during two clearly distinguishable periods of high and low inflation. The results indicate that higher persistence and slower convergence of...

Using monthly zip-code level data on credit card transactions covering 16 U.S. cities, this paper investigates changes in consumption at local commercial places during the early coronavirus disease 2019 (COVID-19) era. Since using aggregate-level data can suppress valuable information on...
