Double-sided adverse selection in the product market and the role of the insurance market

International Economic Review (Impact Factor: 1.56). 02/2010; 51(1):125-142. DOI: 10.1111/j.1468-2354.2009.00573.x

I investigate the interrelation between a product market and an insurance market when adverse-selection problems exist both in consumers and in firms. Firms offer warranties for product failures. Consumers may further purchase first-party insurance for the residual risks of product failures. Given that the insurance market exists, two types of equilibria are possible: (a) Different firm types offer different pooling warranties attracting both good and bad consumer types or (b) good firms attract only bad consumers and bad firms attract both types of consumers. I discuss the existence and the efficiency implication of the insurance market.
