We propose in this paper a model of optimal Carbon Capture and Storage in which the reservoir of sequestered carbon is leaky, and pollution eventually is released into the atmosphere. We formulate the social planner problem as an optimal control program and we describe the optimal consumption...

We explore the link between cyclical and smooth resource exploitation. We define an impulse control framework which can generate both cyclical solutions and steady state solutions. For the cyclical solution, we establish a link with the discrete-time model by Dawid and Kopel (1997). For the...

This paper develops an OLG model with emissions arising from production and potential irreversible pollution. Pollution control goes through a system of permits and private agents can also maintain the environment. In this setting, we prove that there exist multiple equilibria. Due to the...

Cet article utilise un exemple simple pour passer en revue des concepts de mesure de la biodiversité, avec un effort pour expliciter leurs fondements axiomatiques. L'article offre ensuite un aperçu des concepts développés pour sa protection, et il s'achève sur une discussion de quelques...

We study strategic games where players' preferences are weak orders which need not admit utility representations. First of all, we ex- tend Voorneveld's concept of best-response potential from cardinal to ordi- nal games and derive the analogue of his characterization result: An ordi- nal game...

This paper studies optimal pricing in networks in the presence of local consumption or price externalities. It analyzes the relation between prices and nodal centrality measures. Using an asymptotic approach, it shows that the ranking of optimal prices and strategies can be reduced to the...

This paper studies the optimal environmental policy in a mixed market when pollution accumulates over time. Specifically, we assume quantity competition between several private firms and one partially privatized firm. The optimal emission tax is shown to be independent of the weight the...
