In this paper we use a new analytical approach to the Lucas-Uzawa model (Boucekkine and Ruiz-Tamarit, 2007) to extend the existinc results on the dynamics and notably on the imbalance effects arising in the model. The approach does not only allow to extend the traditional analysis to any initial...

Several R&D-based models of endogenous economic growth are investigated under the Solow-like assumption of fixed allocation of resources across activities. We identify model parameters that lead to explosive dynamics and analyse various economic techniques to avoid it. The techniques include...

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...

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...

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...

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...

We develop a dynamic stochastic general equilibrium model with an heterogeneous banking sector. We introduce endogenous default probabilities for both firms and banks, and allow for bank regulation and liquidity injection into the interbank market. Our aim is to understand the interactions...

A dynamic contracting model with endogenous prices, wages and investment is presented. It accounts for capital and labour underutilization at steady state and displays various patterns of unemployment rate and capacity utilization rate co-movements as a function of demand and supply shocks. The...

This paper presents an intertemporal model in which the agents may face different quantity constraints resulting from technological rigidities, microeconomic uncertainty and market segmentation. Its main purpose is to derive the path of the unemployment rate, the rate of capacity utilisation and...
