We examine how policymakers react to a pandemic with uncertainty regarding key epidemiological parameters by embedding a macroeconomic SIR model in a robust control framework. We find that optimal policy under uncertainty generates optimal mitigation responses that are asymmetric with respect to...

The COVID-19 pandemic has forced countries to make difficult ethical choices, e.g., how to balance public health and socioeconomic activity and whom to prioritize in allocating vaccines or other scarce medical resources. We discuss the implications of benefit-cost analysis, utilitarianism, and...

We consider several epidemiological simulations of the COVID-19 pandemic using the textbook SIR model and discuss the basic implications of these results for crafting an adequate response to the ensuing economic crisis. Our simulations are meant to be illustrative of the findings reported in...

We analyze international trade and health policy coordination during a pandemic by developing a two-economy, two-sector trade model integrated into a micro-founded SIR model of infection dynamics. Disease transmission intensity can differ by goods (manufactured versus services and domestic...

How does contagion risk affect the business cycle? We find that the presence of contagion risk significantly alters the transmission of standard macroeconomic shocks. Relative to the first-best equilibrium, the contagion externality significantly reduces the response of output to a technology...

Countries have employed a variety of non-pharmaceutical interventions (NPIs) in order to curtail the COVID-19 pandemic. However, the success of individual measures in reducing the number of infections remains controversial. This paper exploits a panel data set of 107 countries to estimate the...

Antimicrobial resistance (AMR) is currently the focus of much media attention and policy discussion. A historical perspective on AMR suggests that although the challenge of AMR is real, the doomsday tone of most commentary is unwarranted. That is partly because most of the gains in life...
