We model environmental interaction among countries as a policy game where government in each country use quotas or taxes as a strategy variables. The environmental policy has a triple role to play : targeting domestic emission, providing strategic advantages for domestic firms and targeting...

In this article we extend the recent literature on overlapping generations and pollution by allowing each generation’s utility to depend on past levels of pollution. To conform with the literature on habit in consumption we call this extension habit in pollution. Habit in pollution can...

This article considers an economy whose production function takes both renewable and non-renewable resources as inputs. We extend the current literature by allowing for exogneous technical change in the elasticity of subsstitution between these two types of resources. In addition, we study the...

We study a two-sector endogenous growth model where a single consumption good is obtained using a renewable resource in combination with physical capital. Both inputs are essential for production and technical substitutes. In this context we analyze the issues of sustainability, long-run and...

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...

In this paper we consider a simple model of horizontal differentiation and derive the closed form solutions for the level of the variables in the decentralized economy and in the social planner case. This enables us to analyze consumers’ welfare as a function of the parameter representing...

We reconsider the optimal population size problem in a continuous time economy populated by homogenous cohorts with a fixed life span. Linear production functions in the labor input and standard rearing costs are also considered. First, we study under which conditions the successive cohorts will...

Until now most research in dynamic games focus on models with quadratic objective functions because of practical considerations. But in reality, all problems are not quadratic. In this paper, we solve a differential game where players have non-quadratic preferences. In particular we consider an...

The reader will find in this paper a simple theoretical framework where to analyze the usual issues from environmental and economic growth literature, including the problem of global warming, the corresponding climate change, and the impact on economic system. This paper considers two...

The paper provides a continuous-time version of the discrete-time Mitra-Wan model of optimal forest management, where trees are harvested to maximize the utility of timber flow over an infinite time horizon. The available trees and the other parameters of the problem vary continuously with...
