Flood Risk Mapping and the Distributional Impacts of Climate Information
This paper examines the provision of official flood risk information in the United States and its distributional impacts on residential flood insurance take-up. Assembling new data on all flood maps produced after Hurricane Katrina, I first document that updated maps decreased the number of properties zoned in high-risk floodplains and incorrectly omitted five million properties that should have been rezoned inside these areas. Removals and omissions disproportionately occurred in neighborhoods with more Black and Hispanic residents. Leveraging the staggered timing of map updates, I estimate ...

How Much Should We Trust Regional-Exposure Designs?
Many prominent studies in macroeconomics, labor, and trade use panel data on regions to identify the local effects of aggregate shocks. These studies construct regional-exposure instruments as an observed aggregate shock times an observed regional exposure to that shock. We argue that the most economically plausible source of identification in these settings is uncorrelatedness of observed and unobserved aggregate shocks. Even when the regression estimator is consistent, we show that inference is complicated by cross-regional residual correlations induced by unobserved aggregate shocks. We ...
