Working Papers

We study the impact of work permits on formal employment outcomes for Venezuelan refugees in Colombia.

We examine how hiring foreign workers influences firms' market expansion strategies in consumer goods.

Undocumented immigrants in Colombia increased their entrepreneurship rate by a factor of ten after receiving resident visas.

We refine the classic finding that export concentration follows a U-shape with income. Re-specialization is attenuated when resource-rich countries are excluded, and countries continue to diversify within sectors at finer product levels. We complement these findings with a neo-Ricardian trade model.

We study whether immigrant CEOs at large U.S. corporations face asymmetric career consequences. Using a panel of 2,030 CEOs at 752 firms from 2000-2021, we find that immigrant CEOs face a 'tighter leash' where declining performance raises exit risk disproportionately, and analysts ask harder questions at immigrant CEO firms.

Using original survey data from nearly 3,000 Venezuelan migrants across nine Latin American countries, we study the association between legal immigration status and labor market outcomes, and how these jointly relate to settlement intentions.

We construct a novel dataset of approximately 770 dated data center facilities and link them to county-level employment and wage data. Using synthetic control methods, we find that data centers increase information sector employment by 22 percent and construction employment by 11 percent over five to six years.

We study how migration reforms affect cross-border patenting and global innovation patterns in multinational firms.

The 2020 visa restriction announcement reduced Fortune 500 valuations by approximately $100 billion.
