An introduction to economic studies, health emergencies, and COVID-19.

The COVID-19 pandemic has created widespread harm and disruption. Countries have implemented unprecedented measures to protect the lives and livelihoods of their inhabitants. The scope and composition of these responses are shaped, in part, by research and analysis about the estimated economic impacts of the COVID-19 Pandemic and proposed responses to it. This analysis outlines basic features and principles involved in economic studies, specifically economic impact studies and economic evaluations, which have formed a significant part of the ever-increasing evidence base about COVID-19. This analysis introduces economic studies in this context, highlighting what they can do, their limitations, and key steps involved in conducting them. It highlights examples of economic analysis focused on COVID-19 and on health emergencies and disasters more broadly. Knowing how economic studies are conducted, and their limitations, will help introduce how their findings can be a useful, usable, and used part of efforts to tackle this global health crisis.
