This paper studies whether skilled migrants contribute to the host country's "productive efficiency" (Farrell, 1957) using input-output and immigration sectoral data for seven industries in twelve countries during the period 1999-2001. We find that skilled migrants contribute positively to a...

This paper theoretically explores regional firms’ competition in attracting mobile workers under spending cost to evaluate workers’ skills. Using the tax competition literature, we construct a two-region model that expenses on evaluation increase the regional firm productivity. The model...

We document a slowdown in low-skilled immigration that began around the onset of the Great Recession in 2007, which was associated with a subsequent rise in low-skilled wages, a decline in the skill premium, and labor shortages in service occupations. Falling returns to education also coincided...

How do skilled migrant workers affect firms' performance and output? I estimate the causal effect of EU nurse withdrawal after the Brexit referendum on the performance of English hospitals. Exploiting variation in the reliance on EU workers across hospital providers in pre-referendum years, I...

This paper estimates the causal effect of recruitment competition on the labor demand for high-skilled foreign workers. I assemble a new data set, combining a firm-level panel of all Labor Condition Applications (LCAs) submitted as a first step to obtaining H-1B visas between 2010 and 2019 with...

Global migration is heavily skill-biased, with tertiary-educated workers being four times more likely to migrate than workers with a lower education. In this paper, we quantify the global impact of this skill bias in migration. Based on a quantitative multi-country model with trade, we compare...
