The Hammer and the Scalpel: On the Economics of Indiscriminate versus Targeted Isolation Policies during Pandemics
We develop a simple dynamic economic model of epidemic transmission designed to be consistent with widely used SIR biological models of the transmission of epidemics, while incorporating economic benefits and costs as well. Our main finding is that targeted testing and isolation policies deliver large welfare gains relative to optimal policies when these tools are not used. Specifically, we find that when testing and isolation are not used, optimal policy delivers a welfare gain equivalent to a 0.6% permanent increase in consumption relative to no intervention. The welfare gain arises because ...

Temperature and Growth: A Panel Analysis of the United States
We document that seasonal temperatures have significant and systematic effects on the U.S. economy, both at the aggregate level and across a wide cross-section of economic sectors. This effect is particularly strong for the summer: a 1 degree F increase in the average summer temperature is associated with a reduction in the annual growth rate of state-level output of 0.15 to 0.25 percentage points. We combine our estimates with projected increases in seasonal temperatures and find that rising temperatures could reduce U.S. economic growth by up to one-third over the next century.

The Impact of a Man-made Disaster on Consumer Credit Outcomes: Evidence from the 2018 Merrimack Valley Natural Gas Explosions
This paper is the first to empirically examine the impact of a man-made disaster on consumer credit outcomes. It uses the 2018 Merrimack Valley natural gas explosions as a quasi-random natural experiment and shows that the explosions had a temporary negative effect on debt balances, credit limits, and the number of delinquencies, and did not affect credit scores. The decreases in debt balances and credit limits were likely driven by a decline in credit demand when the affected individuals faced severe life disruption, great uncertainty, and negative financial shocks associated with the ...
