WEBINAR RECORDING · 2021-07
Immigration and Trade
In this conversation: Syed Uddin and Philippe Legrain; moderators Hanna Norberg and Ben Shepherd.
Syed Uddin presents evidence linking immigrant networks to US exports across products, skill categories, and trade margins. Philippe Legrain broadens the discussion to entrepreneurship and diversity, while Ben Shepherd asks whether networks serve neighboring markets and whether information is the mechanism behind the estimates.
Session information draws on the recording and its original description. Affiliations and policy context refer to the time of the webinar.
FROM THE CONVERSATION
Three takeaways.
What they mean in practice.
Prepared from the session recording using automatic transcription and editorial review. Follow the timestamp links for the original wording and context.
Immigrant networks are associated with broader and larger exports
Watch 27:48 ↗Uddin studies US subnational exports using immigrant stocks by origin and destination, product quality measures, and gravity controls. His instrumental-variable specification reports about 2 percent more aggregate exports for a 10 percent increase in immigrants, with a larger response for lower-quality products and a prominent extensive-margin contribution.
Policy interpretation: Include export connections in assessments of immigration, beyond immediate labor-market and fiscal effects. Treat the reported elasticity as a result of this study’s specification rather than a universal forecast for an immigration reform.
Skill categories conceal different economic contributions
Watch 38:37 ↗Uddin reports differing contributions across occupational skill groups and product quality. Legrain argues that a high/low-skill distinction misses contacts, perspectives, experience, and complementary tasks, as well as entrepreneurial contributions that can persist beyond the initial migrant generation.
Policy interpretation: Avoid using a single qualification category as a complete measure of contribution. Consider business formation, market knowledge, and interactions with local workers when assessing immigration and enterprise-support policies.
Information and third-market spillovers remain research questions
Watch 47:24 ↗Shepherd asks whether networks from one origin help firms export to neighboring countries and whether information intensity can distinguish the mechanisms behind extensive and intensive margins. Uddin says third-country effects are a separate workstream and that the current paper lacks the firm-level detail needed for the proposed mechanism tests.
Policy interpretation: Do not interpret bilateral export coefficients as a complete accounting of network benefits. Link firm data, product characteristics, and destination networks to test where knowledge travels and which costs it reduces.
From the discussion
At 36:18–37:38, Legrain points to Vietnamese refugee placement and the later lifting of the US embargo as an identification example, not evidence produced by Uddin’s paper. At 55:42–57:04, he illustrates transferable export knowledge with an entrepreneur connecting UK waste paper to Indian demand. At 57:05–60:40, he criticizes points systems for missing task demands and changing needs; this is a policy argument, not a result estimated in the presentation.
