This paper compares drivers of full COVID-19 vaccinations and booster doses across U.S. counties. Booster doses are contingent upon someone receiving the primary doses, and the risk attitudes and propensities to get vaccinated may be different across individuals, along with the supply chain...

We study determinants of COVID-19 vaccine donations from recipients' perspective, especially considering supply chain and institutional weakness (corruption) aspects. Results, based on data from more than 131 nations, show that strengthened supply chains reduced donations. The impacts of...

The risk of recurrent outbreaks following the main waves of a pandemic has been acknowledged. We provide evidence of the scale and duration of this outbreak risk. We compile municipal public health records and use national data to model the stochastic process of mortality rates after the main...

What role do spillover effects play in firm resilience during crises? Using high-frequency data on over 7 million import transactions, we ask this question in the context of the large trade disruption faced by US importers in the months immediately following the initial COVID-19 shock. While US...

We analyze how pandemic business interruption coverage can be put in place by building on capitalization mechanisms. The pandemic risk cannot be mutualized since it affects simultaneously a large number of businesses, and furthermore, it has a systemic nature because it goes along with a severe...

We propose a flexible model of infectious dynamics with a single endogenous state variable and economic choices. We characterize equilibrium, optimal outcomes, static and dynamic externalities, and prove the following: (i) A lockdown generically is followed by policies to stimulate activity....

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...
