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...

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...

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 :...

This paper studies the different mechanisms and the dynamics through which demography is channelled to the economy. We analyze the role of demographic changes in the economic development process by studying the transitional and the long-run impact of both the rate of population growth and the...

This paper aims at investigating relationships between inflation and macroeconomic fluctuations. The theoretical debate associated to this question is important: Whereas the Keynesian expect a countercyclical behavior of inflation, Real Business Cycles theorists, stressing on the supply side,...

L’introduction des profits dans les fonctions d’investissement s’inscrit dans le cadre du retour de l’argument empirique sur les spécifications proposées par Jorgenson. Selon la théorie de la profitabilité les entreprises ont une demande d’investissement croissante avec le rapport...

Une grande partie des politiques de développement repose sur l'envoi de transferts aux économies connaissant des difficultés de développement. Si ces aides semblent favorables au bien être des agents, leurs effets sur la croissance de long terme des économies restent ambigus ou parfois...
