We document that the recent decline in aggregate volatility has been accompanied by a large increase in firm level risk. The negative relationship between firm and aggregate risk seems to be present across industries in the US, and across OECD countries. Firm volatility increases after...

We establish an important role for the firm by studying capital reallocation decisions of mutual fund firms. At least 30% of the value mutual fund managers add can be attributed to the firm's role in efficiently allocating capital amongst its mutual fund managers. We find no evidence of a...

We study the impact of the 1918 Spanish Flu on U.S. stock prices. We use the death rate to control for the impact of the global pandemic and war news reported in the New York Times to capture the positive effects of the end of World War I on stock prices. Using a new weekly hand collected NYSE...

Childhood vaccinations are an important input to disease prevention, but vaccination rates have declined over the last decade due largely to parental fears about vaccine dangers. Education campaigns on the safety of vaccines seem to have little impact. Anecdotal evidence on disease outbreaks...

This paper analyzes the economic impact of the pandemic, providing insights into the consequences of alternative policies. Our framework focuses on three key features: (a) Covid-19 is a sectoral shock of unknown depth and duration affecting some sectors and technologies more than others; (b)...

We analyze the role of international trade and health coordination in times of a pandemic by building a two-economy, two-good trade model integrated into a micro-founded SIR model of infection dynamics. Uncoordinated governments with national mandates can adopt (i) containment policies to...
