This paper shows how models of insurance markets with asymmetric information can be calibrated and solved to yield quantitative estimates of the consequences of government regulation. We estimate the impact of restricting gender-based pricing in the United Kingdom retirement annuity market, a...

Wilson (1977) provided the striking result that the government can always Pareto dominate a pooling equilibrium in a private insurance market with adverse selection by providing the pooling policy as a compulsory public policy and allowing individuals to buy supplementary private insurance. I...

This paper tests for asymmetric information in the U.K. annuity market of the 1990s by trying to identify 'unused observables,' attributes of individual insurance buyers that are correlated both with subsequent claims experience and with insurance demand but that insurance companies did not use...

This paper presents new evidence on the importance of adverse selection in insurance markets. We use a unique data set, consisting of all annuity policies sold by a large U.K. insurance company since the early 1980s, to analyze mortality differences across groups of individuals who purchased...

This paper examines the standard test for asymmetric information in insurance markets: that its presence will result in a positive correlation between insurance coverage and risk occurrence. We show empirically that while there is no evidence of this positive correlation in the long-term care...

In recent years there has been a growing interest in macro models with heterogeneity in information and complementarity in actions. These models deliver promising positive properties, such as heightened inertia and volatility. But they also raise important normative questions, such as whether...

We describe recent advances in the empirical analysis of insurance markets. This new research proposes ways to estimate individual demand for insurance and the relationship between prices and insurer costs in the presence of adverse and advantageous selection. We discuss how these models permit...

This paper studies policy in a class of economies in which information about commonly-relevant fundamentals -- such as aggregate productivity and demand conditions -- is dispersed and can not be centralized by the government. In these economies, the decentralized use of information can fail to...
