In Bangladesh, IPA collaborates with the BRAC Institute of Governance and Development (BIGD). IPA has conducted research focused on entrepreneurship and private sector development, migration, health, sanitation, and other areas. Our work has provided timely data on the forced displacement and migration of Rohingya refugees into Bangladesh. In response to the COVID-19 pandemic, IPA researchers conducted the first large-scale randomized evaluation on the efficacy of using face masks in a real-world setting.
