We develop a model of price competition between insurers where insurers maximize expected profit subject to a solvency constraint. Insurers base prices in part on expected losses, the estimates of which are updated in a Bayesian fashion. We assume that insurers are overconfident—they...

Standard models of adverse selection in insurance markets assume policyholders know their loss distributions. This study examines the nature of equilibrium and the equilibrium value of information in competitive insurance markets where consumers lack complete information regarding their loss...

The analysis considers an insurance market with adverse selection where individuals' loss distributions may differ with respect to both the frequency and severity of loss. We show that the combination of deductibles and coinsurance can be used to sort rationed policyholders. Because of their...

The size distribution of mutual property-liability insurers has a larger proportion of relatively small companies than the size distribution of stock property-liability insurers. Small mutuals are unlikely to offer risk-sharing advantages over conventional insurance, so these firms must offer...

We examine a market with observably heterogeneous risks and a government sponsored guaranty fund and consider whether it is optimal to form a single insurer or separate insurers for each consumer type. Given the economic environment, pooling never dominates the formation of separate insurance...

This study considers a single-period monopolistic insurance market with adverse selection and moral hazard. We find that, where the distortions introduced by moral hazard are sufficiently moderate, the insurer can use price-quantity contracts as a mechanism to simultaneously deal with both...

Standard models of adverse selection in insurance markets assume policyholders know their loss distributions. This study examines the nature of equilibrium and the equilibrium value of information in competitive insurance markets where consumers lack complete information regarding their loss...
