Economy-wide shocks affect demand, supply, and intermediary sectors simultaneously. We dissect the impact of the Covid-19 pandemic on international trade by combining information from customs records, smartphone-based human mobility, and container ship port calls. We find that local disruptions...

Using a gravity-like approach, we study how Covid-19 deaths and lockdown policies affected countries' imports from China during 2020. We find that a country's own Covid-19 deaths and lockdowns significantly reduced its imports from China, suggesting that the negative demand effects prevailed...

We embed a lockdown choice in a simplified epidemiological model and derive formulas for the optimal lockdown intensity and duration. The optimal policy reflects the rate of time preference, epidemiological factors, the hazard rate of vaccine discovery, learning effects in the health care...

This study quantifies the economic impacts of SARS on the four affected Asian economies and the two most affected Chinese regions using synthetic control methods with macroeconomic and remote-sensing nightlight data. For the four affected economies (China, Hong Kong, Taiwan, and Singapore), we...
