La décroissance prévisible de la population terrestre doit plutôt être vue comme un facteur positif de développement à long terme. La transition peut néanmoins être délicate. Les politiques natalistes risquent de privilégier le nombre par rapport à l’investissement dans chaque...

Even in countries where there is a male-biased sex ratio, it is still possible for the marriage market to be balanced if men marry younger women and population is growing. We define a missing Brides Index to reflect the intensity of the possible imbalance at steady state, taking into account the...

Consider an economy populated by males and females, both rich and poor. The society has to choose one of the following marriage institutions: polygyny, strict monogamy, and serial monogamy (divorce and remarriage). After having identified the conditions under which each of these equilibria...

The ELIE scheme of Kolm taxes labour capacities instead of labour income in order to circumvent the distortionary effect of taxation on labour supply. Still, Kolm does not study the impact of ELIE on human capital formation and investment. In this paper, we build an overlapping generations (OLG)...

We explore the complementarities between high-skill emigration and poverty in developing countries. We build a model endogenizing human-capital accumulation, high-skill migration and productivity. Two countries sharing the same characteristics may end up either in a “low poverty/low brain...

In this paper we argue that if the cross-country heterogeneity in productivity is more important than the heterogeneity in government quality, it can be optimal to give more foreign aid to more corrupt countries. We build a multi-country model of optimal aid in which we disentangle the...

We explore the consequences of liberalized credit markets for growth and inequality in a lifecycle economy with physical and human capital accumulation, populated by households of different abilities, and calibrated to match the long-run economic performance of a panel of emerging countries....

We assess the merits of different education systems in a framework that accounts for the joint decision problem of parents regarding fertility and education. Specifically, we compare the implications of a public and a private schooing regime for economic growth and inequality; We find that...

This paper examines the introduction of monopolistic competition into wage bargaining models : in addition to capital-labour substitution, we also consider a cost-push effect. The right-to-manage model requires strong restrictions on the objective functions and leads to problematic conclusions...

We investigate and interpret sorne of the properties of a multi-sectoral growth model with endogenous embodied technical change in the light of the ongoing debate on the viability of an IT based growth regime. In particular. we illustrate the two main views of the 1995-2000 IT boom in the USA....
