The development of a new global health architecture in the wake of Covid-19 will require important decisions to be made, especially when it comes to negotiating a pandemic accord and creating robust supply chains. Against the backdrop of their systemic rivalry, the US and China view global...

We consider a model of network interactions where the outcome of a unit depends on the outcomes of the connected units. We determine the key network link, i.e., the network link whose removal results in the largest reduction in the aggregate outcomes, and provide a measure that quantifies the...

The health risks of the current COVID-19 pandemic, together with the drastic mitigation measures taken in many affected nations, pose an obvious threat to public mental health. The social science literature has already established a clear link between mental health and sociodemographic as well...

This paper examines the causal impact of diagnostic efficiency on the COVID-19 pandemic in China. Using an instrumental variable approach, we show that a 1-day decrease in the time taken to confirm the first case in a city publicly led to 9.4% and 12.7% reductions in COVID-19 prevalence and...

How quickly can we expect human mobility to resume to pre-pandemic levels after lockdowns? Does pandemic severity affect the speed of post-lockdown recovery? Using real-time cross-city human mobility data from China and a difference-in-difference-in-differences framework, we find that mobility...

Introduction: During the second wave of the COVID-19 pandemic, the government interventions used to contain the outbreak in China are effective. However, the effects of different interventions and their combinations can’t be directly observed and are currently understood only through...

How quickly can we expect human mobility to resume to pre-pandemic levels after lockdowns? Does pandemic severity affect the speed of post-lockdown recovery? Using real-time cross-city human mobility data from China and a difference-in-difference-in-differences framework, we find that mobility...

This paper examines the impact of diagnostic efficiency on the COVID-19 pandemic. Using an exogenous policy on diagnostic confirmation, we show that a one- day decrease in the time taken to confirm the first case in a city publicly led to 9.4% and 12.7% reductions in COVID-19 prevalence and...

This paper investigates whether and how the COVID-19 pandemic affects bank funding costs in China. We find a significantly positive relationship between the offering yields of negotiable certificates of deposit and banks’ pandemic exposure. The surge in bank funding costs is alleviated by...
