Ahmed Mushfiq Mobarak, professor of Economics at Yale University with concurrent appointments in the School of Management and in the Department of Economics, discusses his research on COVID-19 response in Bangladesh and beyond, including masking, vaccine equity, and appropriate pandemic response policies in low and middle income countries. He provides an overview of the coauthored MaskNorm study, a randomized-trial of community-level mask promotion in rural Bangladesh during COVID-19 that demonstrates a scalable and effective method to promote mask adoption and reduce symptomatic SARS-CoV-2 infections. He also discusses efficient last-mile vaccine delivery in low-income countries and related research on the lower epidemiological and welfare value of social distancing in lower-income countries. Mobarak is the founder and faculty director of the Yale Research Initiative on Innovation and Scale (Y-RISE). He holds other appointments at Innovations for Poverty Action, the Jameel Poverty Action Lab (J-PAL) at MIT, the International Growth Centre (IGC) at LSE. This event is part of the Asia Health Policy Program (AHPP) 2021-22 Colloquium series "Aligning Incentives for Better Health and More Resilient Health Systems in Asia.”
