Critics of the H-1B program for high-skilled workers argue that the program restricts immigrant job mobility and lacks a vehicle for adjusting the number of visas during a recession. We study the job mobility of highly-skilled Indian IT guest workers and provide new evidence on their inter-firm...

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...

Male immigrants are observed to be disproportionately employed in ICT information and communication technology (ICT) industries and occupations. A measure of basic ICT skills is employed to document differences in skill levels and labour market earnings across immigration classes and categories...

We reevaluate the hypothesis and empirical result that ethnic civil wars lead to higher skilled emigration (Bang and Mitra, 2013). We develop a simple conceptual framework that predicts contrasting results depending upon if the economy is assumed to be agglomerating in skilled labor or...

The objective of this paper is to analyse the role of migrants in innovation in Europe. We use Total Factor Productivity as a measure of innovation and focus on the three largest European countries - France, Germany and the United Kingdom - in the years 1994-2007. Unlike previous research, which...

Highly-educated foreign-born workers can secure legal US employment through the H-1B program. The annual cap on H-1B issuances varies across individuals' US educational experience, H-1B work history, and employer type. Caps are met quickly in most but not all years. This paper exploits these...

The H-1B program allows firms in the United States to temporarily hire high-skilled foreign citizens. H-1B workers are highly concentrated among a small number of firms. We develop a theoretical model demonstrating that this phenomenon is an artifact of policy design: When the government...

We study how random variation in the availability of highly educated, foreign-born workers impacts firm performance and recruitment behavior. We combine two rich data sources: 1) administrative employer-employee matched data from the US Census Bureau; and 2) firmlevel information on the first...

We examine how low and high skilled internal emigration causally affect investments in human capital at origin. We provide theoretical and empirical evidence of a disincentive mechanism through which individuals refrain from education should low skilled emigration prove a viable alternative. Our...

Although labor market "mismatch" often refers to an imbalances in supply and demand across occupations, mismatch within occupations can arise if skill requirements are changing over time, potentially reducing aggregate matching efficiency within the labor market. To test this, we examine changes...
