Insurers' Carbon Underwriting Policies

(with Felix von Meyerinck and Zacharias Sautner)

Abstract: We study the design, determinants, implementation, and real effects of carbon underwriting policies by large insurers. Adoption is more common among insurers from countries with stronger climate policies and less so among specialty and unlisted firms, with coal preceding oil and gas policies. Linking U.S. coal mines to insurers, we show that policy-adopting insurers reduce mine coverage, but implementation is incomplete and heterogeneous. Affected mines are likely to be abandoned and constrained, particularly when access to alternative insurance is limited. Our results are consistent with a simple insurance-supply model augmented with heterogeneous non-actuarial costs faced by insurers.

Uncoordinated Climate Policy and Carbon Leakage: Evidence from Supply Chains

(with Emanuela Benincasa, Miguel Ferreira, and Emilia Garcia-Appendini)

Abstract: We show that uncoordinated climate policies, which expose firms to heterogeneous climate transition risk, induce supply-chain reconfiguration. Following the introduction of California’s cap-and-trade program, relationships involving regulated suppliers are more likely to terminate than otherwise comparable relationships with unregulated suppliers. Regulated suppliers experience operational disruptions, consistent with customers reallocating sourcing to reduce uncertainty about supplier reliability. These effects are concentrated among suppliers in competitive industries and producers of standardized inputs, where customer switching costs are low. The resulting reconfiguration is consistent with carbon leakage: customers that reallocate away from regulated suppliers shift toward supply chains with a higher carbon footprint.
