[eng] The paper analyzes the structure of the French redistribution system, and investigates some directions for a reform. In the first section, we describe the existing system, with a particular emphasis upon incentives and redistribution. We conclude that the French system is redistributive,...

[fre] La sécurisation des prêts pour l'accession à la propriété concerne les organismes de crédit mais aussi la puissance publique, avec le développement des prêts à taux zéro. L'assurance chômage privée des prêts hypothécaires par le secteur concurrentiel est une réponse à un...

We measure heterogeneity in risk aversion among households in Thai villages using a full risk-sharing model and complement the results with a measure based on optimal portfolio choice. Among households with relatives living in the same village, full insurance cannot be rejected, suggesting that...

We derive distributional effects for a non-cooperative alternative to the unitary model of household behaviour. We consider the Nash equilibria of a voluntary contributions to public goods game.

We develop a collective household model with spousal matching in which there exists marital gains to assortative matching and marriage quality for each couple is revealed ex post. Changes in alimony laws are shown to affect existing couples and couples-to-be differently. For existing couples,...
