This paper studies a two-sided search model with the following characteristics: there is a continuum of agents with different types in each population, match utility is nontransferable, and there is a fixed search cost that agents incur in each period. When utility functions are additively...

In an economy with a continuum of individuals, each individual has a stochastic, continuously evolving endowment process. Individuals are risk averse and would therefore like to insure their endowment processes. It is feasible to obtain insurance by pooling endowments across individuals because...

We solve the principal-agent problem of a monopolist insurer selling to an agent whose riskiness (chance of a loss) is private information, a problem introduced in Stiglitz (1977)'s seminal paper. We prove several properties of optimal menus: the highest type gets full coverage (efficiency at...

This paper revisits the well-known result of Radner and Stiglitz (1984) which shows that, under certain conditions, the value of information exhibits increasing marginal returns over some range. Their result assumes that both the number of states and the number of signal realizations are finite,...

We analyze a principal-agent model with moral hazard in which the principal has private information about the technology, and the contract offered by her may signal this information to the agent. We characterize Perfect Bayesian Equilibria of the game that possess the following properties that...

This article analyzes the effects of differential tax treatment of married and single individuals in the United States on marriage formation and composition, divorce, and labor supply. We develop a marriage-market model with search frictions and heterogeneous agents that is sufficiently rich to...

We study a general screening model that encompasses a health insurance market in which consumers have multiple dimensions of private information and a price-setting insurer (e.g., a monopolist or a social planner) offers vertically differentiated contracts. We combine theory and empirics to...

How does the presence of risk sharing affect sorting patterns on productive attributes when there are complementarities among partners' skills in match output? We develop a matching model in which risk-averse agents, who differ in skills, match pairwise for productive purposes. Match output has...
