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...

We first provide an empirical sstudy of the energy-saving technological progress on the ENERDATA database. Energy intensity is shown to decrease over the period 1971-1999 in OECD countries, indicating a significant energy-saving technical progress trend. We also show via semiparametric partially...

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...

The aim of this paper is to assess how three seminal coordination failure models (Diamond ((1982)1991), Howitt (1985) and Roberts (1987) have fared against ‘Keynes’s programme’. The first part of the paper characterises Keyne’s programme as consisting of the following four objectives :...

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...
