High-Skill Migration, Multinational Companies, and the Location of Economic Activity
This paper examines the relationship between high-skill immigration and multinational activity. I assemble a novel firm-level dataset on high-skill visa applications and show that there is a large home-bias effect. Foreign multinational enterprises (MNEs) in the US tend to hire more migrant workers from their home countries compared to US firms. To quantify the general equilibrium implications for production and welfare, I build and estimate a quantitative model that includes trade, MNE production, and the migration decisions of high-skill workers. I use an instrumental variables approach to ...

Firm Heterogeneity and the Impact of Immigration: Evidence from German Establishments
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. We show analytically that ignoring this heterogeneity in the immigrant share leads to biased estimates of the welfare gains from immigration. To do so, we set up and estimate a model where heterogeneous firms choose their immigrant share and then use it to quantify the welfare effects of an increase in the number of immigrants in Germany. Two new adjustment mechanisms arise under firm ...

What Makes Supply Chains More Resilient to Economic Shocks?
The recent supply chain disruptions caused by COVID-19 lockdowns highlighted the importance of understanding supply chain resilience, which is the extent to which supply chains can resist, adapt to and recover from a sudden economic shock. We analyze the various COVID-19 lockdowns across India to understand which supply chains were more resilient to the lockdown disruptions. Firms that bought more complex products and that transacted with fewer and more important suppliers proved to be more resilient by maintaining buyer-supplier relationships through the lockdowns and exhibiting smaller ...

Can Immigration Help Boost Rural Economies in the Fifth District and Beyond
We examine the role of immigration in rural areas. While immigrants tend to concentrate in urban areas, rural areas also significantly benefit from immigration. Agricultural firms, for example, need to hire many immigrants to help with harvesting crops. Past restrictions to immigration in rural areas haven't proven to be very effective in boosting native worker employment in these areas. First, firms respond to such restrictions by investing in new technologies at the expense of labor. Also, native workers seem unwilling to take many jobs in rural areas, which makes immigrants particularly ...

Did U.S. Immigration Policy Influence India’s IT Boom?
We highlight an unintended consequence of U.S. immigration policy for high-skill workers. Indian college students and workers got skills in computer science in the 1990s — a key occupation for innovation and growth — with the prospects of migrating to work in the booming U.S. IT industry. However, many ended up not migrating or returning to India after a short period. These workers helped build the IT sector in India, which grew at outstanding rates in the late 2000s.

How Much Do Multinational Companies in the U.S. Depend on Immigrant Workers?
Foreign multinational firms that operate in the U.S. hire more immigrants from their home countries than from other countries, in part because they facilitate communication between the parent company and the subsidiaries in the U.S. Restrictions to immigration in the U.S. can cause the relocation of production to countries such as India and Canada. Multinational companies drive a big part of this relocation, since they are more intensive on immigrants.

College-Educated Immigrants Bolster U.S. Productivity
The United States is the largest destination in the world for college-educated immigrants, but their path to employment in this country has become increasingly difficult during the past decade, a condition that can hinder productivity growth. This brief discusses the main contributions that college-educated immigrants make to U.S. productivity growth, such as providing scarce skills that supplement and complement those of native workers, contributing disproportionately to innovation and promoting job creation in the United States by foreign-based multinational corporations.

Weathering the Storm: Supply Chains and Climate Risk
We characterize how firms structure supply chains under climate risk. Using new data on the universe of firm-to-firm transactions from an Indian state, we show that firms diversify sourcing locations, and suppliers exposed to climate risk charge lower prices. Our event-study analysis finds that firms with suppliers in flood-affected districts experience a decline in inputs lasting two months, followed by a return to original suppliers. We develop a general equilibrium model of firm input sourcing under climate risk. Firms diversify identical inputs from suppliers across space, trading off the ...
