Classical analysis of health insurance markets often focuses on adverse selection, which creates a direct externality between the enrollees of the same health plan: under an imperfect risk adjustment, the higher the risks of my co-enrollees, the higher my cost of insurance. This has lead to the...

"We set up a two-sided market framework to model competition between a Prefered Provider Organization (PPO) and a Health Maintenance Organization (HMO). Both health plans compete to attract policyholders on one side and providers on the other. The PPO, which is characterized by a higher...

We develop a model where a genetic test reveals whether an individual has a low or high probability of developing a disease. A costly prevention effort allows high-risk agents to decrease this probability. Agents are not obliged to take the test, but must disclose its results to insurers, and...

This paper uses a two-sided market model of hospital competition to study the implications of different remunerations schemes on the physicians’ side. The two-sided market approach is characterized by the concept of common network externality (CNE) introduced by Bardey et al. (2010). This type...

We analyze whether the introduction of unemployment insurance (UI hereafter) benefits in developing countries would reduce the effort made by unemployed to secure a new job in the formal sector. We show that one shot UI benefits unambiguously increase the effort to secure a new job in the formal...

This paper analyzes the regulation of payment schemes for health care providers competing in both quality and product differentiation of their services. The regulator uses two instruments: a prospective payment per patient and a cost reimbursement rate. When the regulator can only use a...

We develop a model in which two insurers and two health care providers compete for a fixed mass of policyholders. Insurers compete in premium and offer coverage against financial consequences of health risk. They have the possibility to sign agreements with providers to establish a health care...
