This paper argues that the financial exposure of households and firms to natural catastrophe disasters is borne primarily by insurance companies. Surprisingly, insurers use reinsurance to cover only a small fraction of these exposures, yet many insurers do not have enough capital and surplus to...

Catastrophe bonds feature full collateralization of the underlying risk transfer, and thus abandon the insurance principle of economizing on collateral through diversification. We examine the theoretical foundations beneath this paradox, finding that fully collateralized instruments have...

In order to encourage entry and lower prices, most regulated markets for health insurance include policies that seek to reduce the uncertainty faced by insurers. In addition to risk adjustment of premiums paid to plans, the Health Insurance Marketplaces established by the Affordable Care Act...

This paper examines the optimal design of insurance and reinsurance policies. We first consider reinsurance for catastrophes: risks which are large for any one insurer but not for the reinsurance market as a whole. Reinsurance for catastrophes is complicated by adverse selection. Optimal...

Life insurers use reinsurance to move liabilities from regulated and rated companies that sell policies to shadow reinsurers, which are less regulated and unrated off-balance-sheet entities within the same insurance group. U.S. life insurance and annuity liabilities ceded to shadow reinsurers...

The theory of insurance is considered here when an insured individual may be able to sue another party for the losses that the insured suffered—and thus when an insured has a potential source of compensation in addition to insurance coverage. Insurance policies reflect this possibility through...

Home equity insurance policies, policies insuring homeowners against declines in the price of their homes, would bear some resemblance both to ordinary insurance and to financial hedging vehicles. A menu of choices for the design of such policies is presented here, and conceptual issues are...

State guaranty funds are quasi-governmental agencies that provide insurance to policyholders against the risk of insurance company failure. But insurance provided by guaranty funds, like all insurance, creates moral hazard problems, especially for companies that are insolvent or near-insolvent....

This paper views abortion access as an insurance policy that protects women from unwanted pregnancies. Within this framework, we present a theoretical model where greater access provides value in the form of insurance against unwanted births and also reduces the incentive to avoid pregnancy....

The problem of establishing the amount of losses covered by public and private insurance is often characterized by asymmetric information, in which the claimant already knows the extent of a loss but this can be demonstrated to the insurer only at a cost. It is shown that a simple arrangement,...
