We present a graphical framework for analyzing both theoretical and empirical work on selection in insurance markets. We begin by using this framework to review the "textbook" adverse selection environment and its implications for insurance allocation, social welfare, and public policy. We then...

We study optimal tax policy in a dynamic private information economy with endogenous private markets. We characterize efficient allocations and competitive equilibria. A standard assumption in the literature is that trades are observable by all agents. We show that in such an environment the...

We study the Rothschild-Stiglitz model of competitive insurance markets with endogenous information disclosure by both firms and consumers. We show that an equilibrium always exists, (even without the single crossing property), and characterize the unique equilibrium allocation. With two types...

Revealed-preference measures of willingness to pay (WTP) capture the value of insurance only against the risk that remains when choosing insurance. This paper provides a method to translate observed market WTP and cost curves into an ex-ante value of insurance that can analyze the impact of...

This paper examines the existence and nature of competitive equilibrium with moral hazard. The more insurance an individual has, the less care will he take. Consequently, insurance firms attempt to restrict their clients' aggregate insurance purchases. If individuals' aggregate insurance...

A large empirical literature found that the correlation between insurance purchase and ex post realization of risk is often statistically insignificant or negative. This is inconsistent with the predictions from the classic models of insurance a la Akerlof (1970), Pauly (1974) and Rothschild and...

We study insurance markets with nonexclusive contracts, introducing bilateral endogenous information disclosure about insurance sales and purchases by firms and consumers. We show that a competitive equilibrium exists under remarkably mild conditions, and characterize the unique equilibrium...
