Dans le cadre d'un modèle à générations imbriquées, nous supposons que la gestion d'une ressource renouvelable correspond à l'émission de quotas d'exploitation transférables. Chaque agent a la possibilité d'utiliser les quotas dans la production ou de les vendre à la génération...

We study the development of a duopoly industry -evolution of firm capacities and competitive behavior- in a continuous-time real-options model of capacity investment. Our methodology allows the evaluation of investment options and exercise rules in a strategic setup. In the initial industry...

We study a simple duopoly model of preemption with multiple investments and instantaneous Bertrand competition in a stochastically growing market. Different patterns of equilibria may arise, depending on the importance of the real option effect. If the average growth rate of the market is close...

Pour une entreprise, le maintien d’une croissance soutenue pendant une longue période est délicat. Il suppose, outre des conditions de marché favorables, un pilotage du rythme de développement adapté aux contraintes financières.

Le modèle standard de concurrence avec antisélection en assurance (Rothschild et Stiglitz) suppose que les types ne diffèrent que par leur probabilité d’accident. Supposant qu’ils puissent aussi différer par leur attitude face au risque, nous mettons en évidence des configurations...

This work aims at analysing the dynamics of macroeconomic fluctuations in Cameroon, using a semi-structural VAR to determine the sources of its macroeconomic fluctuations. The results obtained point out that the macroeconomic fluctuations in Cameroon, even though influenced by external shocks,...

This paper presents some aspects of the consequences of the global crisis in the Asia-Pacific area. In a first section, the mechanisms and the development of the subprime crisis are briefly recalled. In a second section, the effects of the crisis concerning the countries of the region are...

In this work, we are interested in studying the profile synchronization between world economies before and after the concept of globalization and economic integration. Initially, an analysis of features of macroeconomic fluctuations is developed. Two approaches have been developed;the traditional...
