Price, Financial Quality, and Capital Flows in Insurance Markets

This paper develops a model of price determination in insurance markets. Insurance is provided by firms that are subject to default risk. Demand for insurance is inversely related to insurer default risk and is imperfectly price elastic because of information asymmetries and private information in insurance markets. The model predicts that the price of insurance, measured by the ratio of premiums to discounted losses, is inversely related to insurer default risk and that insurers have optimal capital structures. Price may increase or decrease following a loss shock that depletes the insurer's capital, depending on factors such as the effect of the shock on the price elasticity of demand. Empirical tests using firm-level data support the hypothesis that the price of insurance is inversely related to insurer default risk and provide evidence that prices declined in response to the loss shocks of the mid-1980s.Journal of Economic LiteratureClassification Numbers: G22, G32, G33.
