We study the welfare effects of government-backed FDIs in Africa’s farmlands. We build an occupational choice model featuring four mechanisms driving these effects. First, local farming is subject to social arrangements prescribing that farmers share their crop surplus with kin. Second,...

We develop a model of a competitive rental housing market with endogenous default due to income uncertainty. There is a large number of identical, potential suppliers who each face a fixed cost of entering the rental housing market. Those suppliers who choose to enter decide how many rental...

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...

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...

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...

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 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...

Dans cet article, je considère un modèle collectif d'offre de travail sous l'hypothèse que la consommation est purement publique. Je montre, ensuite, que le processus de décision peut être décrit par un équilibre de Lindahl. Les dotations, les préférences et les prix du bien public de...

In the informal economy of developing countries, female entrepreneurs face a comparative disadvantage for operating high-productivity activities, owing to the prevalence of patriarchal forms of business regulations. Yet, for microfinance institutions (MFIs) to succeed in enhancing female...
