We specify and implement a test for the importance of network effects in determining the establishments at which people work, using recently-constructed matched employer-employee data at the establishment level. We explicitly measure the importance of network effects for groups broken out by...

We examine the impact of state level legislation against the hiring of unauthorized immigrants on employment opportunities among competing low-skilled workers. Our focus is on the role of E-Verify mandates and specifically, we test for effects of the 2007 Legal Arizona Workers Act (LAWA) on...

Using US local labor markets between 1990 and 2010, we analyze the heterogeneous impact of rising trade exposure on employment growth of 'good' and 'bad' jobs. Three salient findings emerge. First, rising local exposure to import competition, via falling US tariffs or rising Chinese import...

We offer an integrated explanation and empirical analysis of the polarization of U.S. employment and wages between 1980 and 2005, and the concurrent growth of low skill service occupations. We attribute polarization to the interaction between consumer preferences, which favor variety over...

This paper evaluates counselling programmes in an equilibrium matching model where workers are heterogeneous in skill levels. Job search effort, labour demand and wages are endogenous. When wages are bargained over, raising the effectiveness of or the access to counselling programmes pushes...

The cause of immigrant education mismatch in the host country labour market might not necessarily be discrimination or imperfect transferability of human capital, as argued in previous studies. Immigrants who have gained professional experience in the home country in jobs below their education...

U.S. employers can check whether the workers they hire are legally eligible for employment using E-Verify, a free electronic system run by the federal government. We use confidential data from the U.S. Department of Homeland Security to provide the first examination of whether increases in...

We employ employer-employee matched data from Denmark and utilize plausibly exogenous variation in the rise of import competition due to the dismantling of import quotas as China entered the World Trade Organization to show, first, that rising import competition has led to reduced employment in...

After a decade in which wages and employment fell precipitously in low-skill occupations and expanded in high-skill occupations, the shape of U.S. earnings and job growth sharply polarized in the 1990s. Employment shares and relative earnings rose in both low and high-skill jobs, leading to a...
