This paper studies the design of health insurance with ex post moral hazard, when there is imperfect competition in the market for the medical product. Various scenarios, such as monopoly pricing, price negotiation or horizontal differentiation are considered. The insurance contract specifies...

This paper studies how the risk of divorce a¤ects the human capital decisions of a young couple. We consider a setting where complete specialization (one of the spouses uses up all the education resources) is optimal with no divorce risk. Symmetry in education (both spouses receive an equal...

This paper studies the design of couples’ income taxation when consumption and labor supply decisions within the couple are made by maximizing a weighted sum of the spouses’ utilities; bargaining weights are given but specific to each couple. Information structure and labor supply decisions...

Individuals, differing in productivity and life expectancy, vote over the size and type of a collective annuity. Its type is represented by the fraction of the contributive (Bismarckian) component (based on the workers past earnings) as opposed to the non- contributive (Beveridgean) part (based...

We study exchanges between three overlapping generations with non-dynastic altruism. The middleaged choose informal care provided to their parents and education expenditures for their children. The young enjoy their education, while the old may leave a bequest to their children. Within each...

We show that the celebrated Atkinson and Stiglitz (1976) result on the uniformity of the commodity tax rates when preferences are weakly separable between goods and leisure does not hold when (at least) one of the goods is produced within the household. The result is restored if preferences are...

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...

A wide variety of social protection systems coexist within the EU. Some member states provide social insurance that is of Beveridgean inspiration (with universal and more or less flat benefits), while others offer a system that is mainly Bismarckian (with benefits related to past contributions)....

This paper examines if an energy price shock should be compensated by a reduction in energy taxes to mitigate its impact on consumer prices. Such an adjustment is often debated and advocated for redistributive reasons. Our investigation is based on a model that characterizes second-best optimal...

This paper studies the determination of informal long-term care (family aid) to de- pendent elderly in a worst case scenario concerning the harmonyof family relations. Children are purely sel…sh, and neither side can make credible commitments (which rules out e¢ cient bargaining). The model is...
