Consider an n-person economy in which efficiency is independent of distribution but the cardinal properties of the agents’ utility functions precludes transferable utility (a property we call “Almost TU”). We show that Almost TU is a necessary and sufficient condition for all agents to...

We study the effect of heterogeneous growth in demand on resource extraction. Using the Great Fish War framework of Levhari and Mirman (1980), we show that heterogeneity in demand growth has a profound effect on both cooperative and non-cooperative solutions.

The literature on household behavior contains hardly any empirical research on the within-household distributional effect of tax-benefit policies. We simulate this effect in the framework of a collective model of labor supply when shifting from a joint to an individual taxation system in France....

Consider a model of bargaining, in which two players, 1 and 2, share a pie of size y. The bargaining environment is described by a set of parameters ? that may affect agents' preferences over the agreement sharing, the status quo outcome, or both. The outcomes (i.e., whether an agreement is...

Research on the effects of informal child fostering arrangements on the welfare of the children involved highlights cross-country disparities. Why may there be differences across countries with regard to the effects of informal child fostering arrangements? If in all countries reporting a high...

Notre société fait face à de nombreux risques qui affectent des vies humaines. Les autorités publiques doivent donc déterminer le budget optimal à consacrer à chaque projet visant à diminuer ces risques sociaux. L’analyse avantages-coûts est un outil très utilisé pour...

Polygyny is an institution with deep roots in West Africa. Many papers have attempted to explain the rationality and persistence of this phenomenon through time. Less effort has been devoted to studying the effect of polygyny on household economic behavior. This question is policy relevant given...

In Chiappori's (1988) collective model of labor supply hours of work are supposed flexible. In many countries, however, male labor supply does not vary much. In that case, the husband's labor supply is no longer informative about the household decision process and individual preferences. To...

This paper analyzes how economic policies can influence parents’ decisions about their children’s schooling, household work and leisure in South Africa. Using a dynamic computable general equilibrium model that integrates both market and non-market activities, distinguishing male and female...

We consider the collective model of labor supply with marketable domestic production (Chiappori, 1997). We first show that, if domestic production is mistakenly ignored by the economist, welfare analyses will be probably distorted. Precisely, the identification of "collective" indirect utilities...
