This paper provides a complete characterization of equilibria in a game-theoretic version of Rothschild and Stiglitz's (1976) model of competitive insurance. I allow for stochastic contract offers by insurance firms and show that a unique symmetric equilibrium always exists. Exact conditions...

We study the existence of a profitable unemployment insurance market in a dynamic economy with adverse selection rooting in information on future job losses. The new feature of the model is that the insurer and workers interact repeatedly. Repeated interactions make it possible to threaten...

A tontine provides a mortality driven, age-increasing payout structure through the pooling of mortality. Because a tontine does not entail any guarantees, the payout structure of a tontine is determined by the pooling of individual characteristics of tontinists. Therefore, the surrender decision...

The standard economic analysis of the insured-insurer relationship under moral hazard postulates a simplistic setup that hardly explains the many features of an insurance contract. We extend this setup to include the situation that the insured was facing at the time of the accident and the...

Risk classification refers to the use of observable characteristics by insurers to group individuals with similar expected claims, compute the corresponding premiums, and thereby reduce asymmetric information. Risk classification can be used to mitigate adverse selection and improve insurance...

The standard economic analysis of the insured-insurer relationship under moral hazard postulates a simplistic setup that hardly explains the many features of an insurance contract. We extend this setup to include the situation that the insured was facing at the time of the accident and the...

We show that on-demand insurance contracts, an innovative form of coverage recently introduced through the InsurTech sector, can serve as a screening device. To this end, we develop a new adverse selection model consistent with Wilson (1977), Miyazaki (1977) and Spence (1978). Consumers have...

The annuity market in the US has been historically small. What drives this fact? The annuity market could be small because of adverse selection or supply-side frictions in insurance markets. Identifying demand- and supply-side frictions is difficult without data separately measuring exogenous...

Can variations in immunization rates be accounted for by differences in information and commitment technologies? I document four salient facts regarding DPT vaccination rates: (i) lower immunization in countries with greater costs of contract enforcement, (ii) higher volatility in immunization...
