In April of 2007 and 2008, the U.S. randomly allocated 65,000 H-1B temporary work permits to foreign-born skilled workers. About 88,000 requests for computer-related H-1B permits were declined in each of those two years. This paper exploits random H-1B variation across U.S. cities to analyze how...

We study a reform that granted European cross-border workers free access to the Swiss labor market and had a stronger effect on regions close to the border. The greater availability of cross-border workers increased foreign employment substantially. Although many cross-border workers were highly...

We develop a dynamic political-economic theory of welfare state and immigration policies, featuring three distinct voting groups: skilled workers, unskilled workers, and old retirees. The essence of inter- and intra-generational redistribution of a typical welfare system is captured with a...

We use longitudinal data from the income tax system to study the impacts of firms’ employment and wage-setting policies on the level and change in immigrant-native wage differences in Canada. We focus on immigrants who arrived in the early 2000s, distinguishing between those with and without a...

The impending retirement of the baby boom cohort represents the first time in the history of the United States that such a large and well-educated group of workers will exit the labor force. This could imply skill shortages in the U.S. economy. We develop near-term labor force projections of the...

We study the impact of firm level choices of ICT, R&D, exporting and importing on the evolution of productivity and its bias towards skilled occupations. We use a novel measure of the propensity of a firm to engage in technology investment and adoption: its employment of workers with STEM...

Concerns that there are problems with the supply of skills, especially education-related skills, in the US labor force have exploded in recent years with a series of reports from employer-associated organizations but also from independent and even government sources making similar claims. These...

We develop a model of international trade with heterogeneous firms and endogenous quality choices. Producing higher quality involves returns to scale, it is intensive in skilled labor and high-quality inputs. Firms' quality choices are interrelated because firms sell their goods to consumers and...

Adapting our earlier model of multinationals, we address policy issues involving wages and labor skills. Multinational firms may arise endogenously, exporting their firm-specific knowledge capital to foreign production facilities, and geographically fragmenting production into skilled and...

Gains from productivity and knowledge transmission arising from the presence of foreign firms has received a good deal of empirical attention, but micro-foundations for this mechanism are weak . Here we focus on production by foreign experts who may train domestic unskilled workers who work with...
