This paper provides an analysis of the health insurance and health care consumption. A structural microeconomic model of joint demand for health insurance and health care is developed and estimated using full maximum likelihood method using Swiss insurance claims data for over 60 000 adult...

This paper is a first attempt to connect the heterogeneity in bank efficiency with lending fluctuations and allocation efficiency: there is a trade-off between the two in the presence of heterogeneity in bank monitoring efficiency. The mechanism at hand is twofold. (a) First the rent extracted...

We characterize the set of second-best optimal "menus" of student-loan contracts in a simple economy with risky labour-market outcomes, adverse selection, moral hazard and risk aversion. The model combines student loans with an elementary optimal income-tax problem. The second-best optima...

Focussing on their analysis of the optimal public goods provision problems, this paper follows the parallel development of equilibrium models and mechanism design after the accommodation of Samuelson's definition of collective goods to the general equilibrium framework. Both paradigms lead to...

This paper attempts to re-examine the notion of equality, going beyond the classic opposition in France between affirmative action and meritocratic equality. Hence, we propose shifting the French debate about equality of opportunities in education to the question of how to raise equality of...

In this paper, we develop an adverse selection model where a monopoly choices a non-linear pricing associated with an investment level which defines the technology of production used. We show that, in general, to implement a non-linear pricing the monopoly choice a level of investment, which...

According to several studies, agricultural carbon sequestration could be a relatively low cost opportunity to mitigate greenhouse gas (GHG) concentration and a promising means that could be institutionalised. However the potential for additional carbon quantities in agricultural soils is...

This paper applies to adverse selection theory the advances made in the field of ambiguity theory. It shows that i) a relevant second-best contract induces no production distortion considering the efficient agent as in the standard case. But the principal has to pay a higher information rent...
