Inflation equals the product of two terms: an extensive margin (the fraction of items with price changes) and an intensive margin (the average size of those price changes). The variance of inflation over time can be decomposed into contributions from each margin. The extensive margin figures...

In this paper we analyze the effect of immigrants on native jobs in fourteen Western European countries. We test whether the inflow of immigrants in the period 1996-2007 decreased employment rates and/or if it altered the occupational distribution of natives with similar education and age. We...

We report results from the first systematic study of the mobility of scientists engaged in research in a large number of countries. Data were collected from 17,182 respondents using a web-based survey of corresponding authors in 16 countries in four fields during 2011. We find considerable...

Tracking individual workers across jobs after Brazil's trade liberalization in the 1990s shows that tariff cuts trigger worker displacements, but neither exporters nor comparative-advantage sectors absorb trade-displaced labor. On the contrary, exporters separate from significantly more and hire...

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...

We test for evidence of spatial, residence-based labor market networks. Turnover is lower for workers more connected to their neighbors generally and more connected to neighbors of the same race or ethnic group. Both results are consistent with networks producing better job matches, while the...

We develop a theory of the market for individual reputation, an indicator of regard by one's peers and others. The central questions are: 1) Does the quantity of exposures raise reputation independent of their quality? and 2) Assuming that overall quality matters for reputation, does the quality...

A recent literature has advanced the use of Engel curves to estimate overall CPI bias. In this paper, I show that the methodology is sensitive to the modeling of household demography. Existing estimates of CPI bias do not account for the changing effect of household size on budget shares, and...

We study whether workers progress up firm wage and size job ladders, and the cyclicality of this movement. Search theory predicts that workers should flow towards larger, higher paying firms. However, we see little evidence of a firm size ladder, partly because small, young firms poach workers...
