Ce papier développe un modèle de croissance endogène avec un secteur d'accroissement de la variété des biens intermédiaires qui regroupe des firmes technologiquement hétérogènes et qui sont en concurrence monopolistique. La structure du marché de l'équilibre de long terme est...

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 develop a simple open-economy AK model with collateral constraints that accounts for growth-reversal episodes, during which countries face abrupt changes in their growth rate that lead to either growth miracles or growth disasters. Absent commitment to investment by the borrowing country,...

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...

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...

According to AK growth models, permanent changes in investment rates have permanent effects on a country’s rate of economic growth. Jones (Quarterly Journal of Economics, 1995, 110, 495-525) finds strong evidence against this prediction studying the time series properties of GDP growth rates...

Abstract: The first challenge for economic growth theory is to understand the transition from stagnation to growth at the time of the Industrial Revolution and in particular to identify the main factor(s) that triggered the take-off. Doing so also helps to understand why there are poor and rich...

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...

A benchmark AK optimal growth model with maintenance expenditures and endogeneous utilization of capital is considered within an explicit vintage capital framework. Scrapping is endogenous, and the model allows for a clean distinction between age and usage dependent capital depreciation and...

This paper examines the role of public education in the context of parental migration, and it studies the effects of an expansive income tax policy that is adopted to increase public education expenditure per pupil. It is shown that such a policy may exacerbate income inequality in the long run...
