We study how international trade affects manufacturing employment and the relative wage of unskilled workers when goods and services are traded with different intensities. Manufacturing trade reduces manufacturing prices worldwide, which reduces manufacturing employment if manufactures and...

We study variation in skill demands for professionals across firms and labor markets. We categorize a wide range of keywords found in job ads into ten general skills. There is substantial variation in these skill requirements, even within narrowly defined occupations. Focusing particularly on...

Globalization has been blamed for rising inequality in rich and poor countries. Yet the views of many protagonists in this debate are not based on evidence. To help form an evidence-based opinion, I review in this paper the theoretical and empirical literature on the relationship between...

Technical change, even if it is limited in scope, can have employment, output, price and wage effects that ripple through the whole economy. This paper uses a flexible and tractable framework, with heterogeneous workers and technologies, and many tasks/goods, to analyze the general equilibrium...
