We develop a specific-factors model of regional economies that includes two types of workers, skilled and unskilled. The model delivers a simple equation relating trade-induced local shocks to changes in local skill premia. We apply the methodology to Brazil's early 1990s trade liberalization...

We study cross-country differences in price and quality in the market for semiconductor wafer manufacturing services. Using a proprietary transaction-level data set, we document i) substantial constant-quality price differences across suppliers, and ii) shifts toward lower priced suppliers....

This paper studies price and quality differences across international intermediate input suppliers. We develop price measures that account for (i) differences in product characteristics, (ii) unobserved quality differences, and (iii) pure (frictional) price dispersion across suppliers. Using...

This paper estimates the effect of local labor market conditions on crime in a developing country with high crime rates. Contrary to the previous literature, which has focused exclusively on developed countries with relatively low crime rates, we find that labor market conditions have a strong...
