Regulatory Capital and Catastrophe Risk
AbstractIn this study, we examine the effect of capital regulation on insurers' pricing behavior using homeowners' insurance price data. We leverage a regulatory reform that imposes greater regulatory capital costs for insurers to provide property coverage in catastrophe-prone areas. We first document that the regulatory capital reform had a meaningful impact on insurers—on average, regulatory capital ratios appear to decline by 50 percentage points. Using a difference-in-differences design and homeowners insurance prices, we find empirical evidence that the reform results in price increases, though the magnitude of the increases is restrained. Taken together with the size of the homeowners' insurance market, our back-of-the-envelope calculation suggests the increase in insurance price is commensurate to 7-14% of the increase in regulatory capital costs due to catastrophes. We also find that the increase in price is larger for insurers with greater regulatory capital constraints or less access to reinsurance markets. Overall, our study provides evidence that climate-related regulation costs can passed on to consumers.
Transmission Effect from Insurers’ Climate Risk Disclosures on their Corporate Bond Investees’ Environmental Friendliness
AbstractWe investigate how insurers’ mandatory climate risk disclosure affects their corporate bond investees’ environmental friendliness. We employ the U.S. insurance industry’s adoption of the Climate Risk Disclosure Survey (CRDS) and a difference-in-differences research design. We find that adoption reduces investees' carbon emission intensity if insurers affected by the CRDS also own a significant amount of the investees’ bonds. This outcome is consistent with investors’ mandated climate risk disclosure having a positive insurer-to-investee transmission effect on investees’ environmental performance. The reduction in carbon emission intensity is more pronounced when the insurers and/or their investees experience more climate-related public pressure to be more climate friendly, when the insurers are likely to more closely monitor their investees, when the investees are more dependent on financing from the insurers, and when the insurers face less underwriting competition.
Optimal Consumption and Investment Decisions with Disastrous Income Risk: Revisiting Rietz’s Rare Disaster Risk Hypothesis
AbstractIn this paper, we develop an analytically tractable dynamic model of optimal consump-tion and savings decisions with disastrous income risk. We ﬁrst empirically explore the relations among consumption changes, aggregate income, disaster shock severity, and ﬁscal measures in 55 countries during the Covid-19 period. We then by empirical motivation investigate an important role of insurance with a focus on the recovery of income in a dis-aster. We highlight how extent of the disastrous income risk to which the agent is exposed and her income recovery post disaster jointly aﬀect the agent’s optimal decisions. Overall, availability of insurance can be particularly important for both the poor and the wealthy in the sense that they could even consume more, save less, and invest more post disaster as long as their future income is (partly) recovered.
