We study the role and structure of commodity taxes when consumption and labor supplies are determined through a bargaining procedure between spouses, and where an optimal income tax is also available. We focus on the question whether there should be differences in tax treatment between "female"...

We consider an unhealthy good, such as a sugar-sweetened beverage, the health damages of which are misperceived by consumers. The sugar content is endogenous. We first study the solution under “pseudo” perfect competition. In that case a simple Pigouvian tax levied per unit of output but...

Abstract This paper studies the design of doctors' remuneration schemes. Two for-profit hospitals compete to attract patients and to affiliate doctors. The numbers of patients and doctors determine an hospital's quality level which is valued on both sides. Quality can be enhanced by doctors...

Abstract We study the design of retirement and disability policies and illustrate the often observed exit from the labor force of healthy workers through disability insurance schemes. In our model, two types of individuals, disabled and leisure-prone ones, have the same disutility for labor and...

This paper studies the optimal non linear income tax of couples. We build a general unitary model of labor supply and allow multidimensional heterogeneity in a discrete type framework. We concentrate our analysis on the resulting intra-family labor allocation of labor supplies and show that this...

We study the design of optimal (private and/or social) insurance schemes for formal home care and institutional care. We consider a three period model. Individuals are either in good health, lightly dependent or heavily dependent. Lightly dependent individuals can buy formal home care which...

The paper studies the design of couples income taxation when consumption and labor supply decisions within the couple are made in a cooperative way according to some bargaining scheme.

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...
