This analysis proposes new measures of rent creation or (notional) mark-up and workers' share of rents on cross-country-industry panel data. While the usual measures of mark-up rate implicitly assume perfect labor markets, our approach relaxes this assumption, and takes into account that part of...

We document a new finding regarding changes in labor market outcomes for men and women in the US. Since 1980, conditional on being a college-educated man, the probability of working in a cognitive/high-wage occupation has fallen. This contrasts starkly with the experience for college-educated...

The changes in technology that took place in the US during the last three decades, mainly due to the introduction of computerization and automation, have been characterized as "routine-substituting." They have reduced the demand for routine tasks, but have increased the demand for analytical...

We model a market for a skill that is in short supply and high demand, where the presence of charlatans (professionals who sell a service that they do not deliver on) is an equilibrium outcome. We use this model to evaluate the standards and disclosure requirements that exist in these markets....

Using the National Survey of College Graduates, I investigate the degree to which holders of temporary work visas in the United States are mobile between employers. Holders of temporary work visas either have legal restrictions on their ability to change employers (particularly holders of...

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 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...

The goal of this paper is to draw attention to the long lasting effect of education on economic outcomes. We use the relationship between education and two routes to early retirement - the receipt of Social Security Disability Insurance (DI) and the early claiming of Social Security retirement...
