Clustering in Natural Disaster Damages
Empirical research in climate economics often relies on panel regressions of different outcomes on disaster damages. Interpreting these regressions requires an assumption that error terms are uncorrelated across counties and time, which climate science research suggests is unlikely to hold. We introduce a methodology to identify spatial and temporal clusters in natural disaster damages datasets, and show that accounting for clustering affects observed economic effects of disasters. Specifically, counties tend to experience 0.45% more disaster damage for every 1% increase in damage across ...

Climate Change and Consumer Finance: A Very Brief Literature Review
Extant research shows that climate change can impose significant costs on consumers’ wealth and finances. Both sea-level rise and flooding from hurricane events led to high price declines and thus wealth loss for homes in coastal areas or in disaster-struck areas, with effects lingering for a number of years in some cases. In terms of consumer finance, while the average consumer is not always significantly negatively affected by a disaster, the vulnerable groups (those with low credit scores and who are low income) can be severely affected, experiencing higher rates of delinquencies and ...

Do Bill Shocks Induce Energy Efficiency Investments?
Inattention can lead to suboptimal investment in energy efficiency. We study whether electricity bill shocks draw attention to the benefits of home energy efficiency investments. Our novel identification strategy builds on the fact that prolonged extreme weather events (which raise electricity costs for many customers) fall within a single billing cycle for some customers but are split across cycles for others. We find that households exposed to average sized bill shocks are 22 percent more likely to invest in energy efficiency than households with normal bills. This result suggests that ...

Drought Risk to the Agriculture Sector
Drought is a perennial and long-term risk that can negatively affect the farm economy through lower yields, loss of crops, reduced farm revenues, and lower sales for farm suppliers. As risks from climate change mount, understanding how drought will affect farmers across the country has become even more important. Drought risk can vary by region, crop type, and production method, and may disproportionately affect some farmers more than others. Although many farmers have crop insurance to protect against losses, insurance does not cover all of their crop’s value, and even insured farmers face ...

Banking on Deforestation: The Cost of Nonenforcement
Despite surging environmental laws, how their enforcement influences banks’ management of climate risks remains underexplored. Using the Brazilian Amazon as a laboratory, we examine the impact of a shock to environmental law enforcement capacity on bank management of risks arising from deforestation — a significant but understudied climate risk. After enforcement declined, Brazilian banks significantly altered their priorities to more short-term profitability over longer-term risk concerns. Banks greatly increased lending to agribusinesses engaged in deforestation and actively shifted ...
