Had U.S. immigration been more restrictive, the IT sectors in both the U.S. and India might have been worse off.

Restrictions on immigration could cause production to shift away from the U.S. to other countries.

The lockdowns resulting from COVID-19 provide an opportunity to examine what factors affect the strength of supply chains.

When immigration is restricted in rural areas, native workers don't seem to fill the jobs left empty.

Increasing labor competition may drive wages down, but natives and immigrants specializing in working for different firms helps offset this effect.

College-educated immigrants provide scarce skills that complement those of U.S. workers, contribute disproportionately to innovation and promote job creation by foreign-based multinationals.

We study how random variation in the availability of highly educated, foreign-born workers impacts firm performance and recruitment behavior.

While supply chain diversification helps mitigate climate risk, it exacerbates the distributional effects of climate change by reducing wages in regions prone to more frequent shocks.

In this paper, we use new data on daily firm-to-firm transactions from India, coupled with a large exogenous shock that disrupted supply chains to varying degrees.

We use a detailed establishment-level dataset from Germany to document a new dimension of firm heterogeneity: large firms spend a higher share of their wage bill on immigrants than small firms.

This paper aims to understand the relationship between high-skill immigration and multinational activity.
