Beyond natural sterility, there are two main types of childlessness: one driven by poverty and another by the high opportunity cost to child-rearing. We argue that taking childlessness and its causes into account matters for assessing the impact of development policies on fertility. We measure...

In this paper, we have developed a two-period overlapping-generation model featuring the effects of child nutrition in developing countries. The model gives rise to multiple equilibria including a poverty trap. It shows that child nutrition status may affect the development of human capital...

We provide a theory that is able to account for the observed comovement between the shift in intergenerational living arrangements from coresidence to non-coresidence and economic development. Our theory is consistent with the diminution in the status of the elderly documented by some...

We examine the pathways by which gender inequality affects fertility and hampers growth. We introduce several dimensions of gender inequality into a 2-sex OLG model with a non-unitary representation of household decision-making. We characterize a Malthusian corner regime which is characterized...

Among possible lifestyles, the DINKs (“double income no kids”) are couples choosing to be childless, while the DEWKs (“dually employed with kids”) are couples with children. We develop a theory of marriage and parenthood decisions, where we distinguish the choice to have children from...

We bridge the gap between the standard theory of growth and the mostly static theory of corruption. Some public investment can be diverted from its purpose by corrupt individuals. Voters determine the level of public investment subject to an incentive constraint equalizing the returns from...

We study the political economy of social insurance with double heterogeneity of voters (i.e., different income and risk levels). Social insurance is financed through distortionary taxation and redistributes across income and risks. Individuals vote over the extent of social insurance, which they...

Corruption is thought to prevent poor countries from catching-up. We analyze one channel through which corruption hampers growth : public investment can be distorted in favor of specific types of spending for which rent-seeking is easier and better concealed. To study this distortion, we propose...

Cet article étudie le rôle redistributif d'une assurance sociale exclusive en présence d'un mécanisme d'imposition directe optimale. Les agents sont caractérisés par une productivité individuelle et un risque maladie. La réalisation de ce risque engendre une dépense de santé ainsi...

Cet article compare les différentes hypothèses d'altruisme qui ont été étudiées dans le cadre du modèle à générations imbriquées. Deux visions concurrentes de l'altruisme se côtoient. La première due à Barro [1974] est proche de l'intuition que l'on peut avoir des solidarités au...
