LISER is proud to announce that our colleague, Professor Catia Batista, has published a groundbreaking paper in Science, one of the world’s most prestigious academic journals. Catia is currently spending the academic year at LISER through the Crossing Borders Programme, on leave from the Nova School of Business and Economics with her husband, Professor Pedro Vicente.

What’s the paper about?

Titled Brain Drain or Brain Gain? Effects of High-Skilled International Emigration on Origin Countries, the paper offers a compelling reassessment of the long-debated phenomenon of skilled migration from low-income to high-income countries. Drawing on causal evidence and empirical studies, the authors demonstrate that far from simply depleting a country’s talent, migration can increase the overall stock of human capital at home. Through remittances, return migration, knowledge spillovers, and education incentives, skilled emigration often creates new opportunities and boosts development at the origin. The paper also highlights conditions and policy environments that can tilt the balance toward brain gain.

Why it matters?

This study corroborates prior research by LISER’s permanent staff on migration and development. It reframes the global migration debate and opens new doors for policy innovation—suggesting that well-managed mobility can be a powerful lever for development.
