Can Trade Help Mitigate Risk From Weather Disruptions?
As weather-related disruptions become more frequent, firms face increasing risks to their supply chains. To safeguard against these shocks, businesses are adopting strategies to enhance resiliency and ensure that disruptions to key suppliers don't halt operations. In the 2024 working paper by several authors of this article (Juanma, Gaurav, Nicolas and Nitya), we explore how Indian firms mitigate risks from weather events by diversifying their input sources across multiple regions.Using detailed transaction data from Indian firms, we highlight multisourcing as a crucial risk-management ...

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 ...

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 ...

How Do College-Educated Immigrants Affect US Firms and Workers?
We study the impact of hiring a college-educated immigrant through the H-1B lottery on the performance and hiring behavior of U.S. firms. When firms win the H-1B lottery, they expand in terms of employment and revenues. Lottery winners are also more likely to stay active. The firms that benefit the most from immigrant workers are small, high-productivity firms. A majority of existing workers at the firm benefit from being exposed to an H-1B coworker, but there are interesting dynamics across different types of workers that we further elucidate.

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 ...

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 ...

Supply Chain Resilience and the Effects of Economic Shocks
Supply chains have long been integral to the U.S. economy, allowing firms to capitalize on specialization and efficiency. However, recent developments like the COVID-19 pandemic, global geopolitical tensions and increasing climate risk have revealed their vulnerabilities as well as their abilities to propagate and amplify economic shocks. In response, firms and policymakers are increasingly focusing on strategies to bolster supply chain resilience. This article explores how economic shocks can propagate through the supply chain, the trade-offs associated with resilience investments, and ...

The IT Boom and Other Unintended Consequences of Chasing the American Dream
We study how US immigration policy and the Internet boom affected not just the US, but also led to a tech boom in India. Students and workers in India acquired computer science skills to join the rapidly growing US IT industry. As the number of US visas was capped, many remained in India, enabling the growth of an Indian IT sector that eventually surpassed the US in IT exports. We leverage variation in immigration quotas and US demand for migrants to show that India experienced a 'brain gain' when the probability of migrating to the US was higher. Using detailed data on higher education, ...

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.

Understanding the Potential Impact of H-1B Visa Program Changes
A new policy proposal would require firms to pay a one-time fee of $100,000 to hire an immigrant college graduate under the H-1B visa program.The policy would likely reduce the total number of college-educated immigrants in the U.S., with universities as well as companies in the IT sector among organizations most likely affected.Research shows that firms expand when they hire H-1B workers without significantly displacing Americans. Firms might respond to this policy change by offshoring their operations to countries such as Canada or India.
