We investigate economic depreciation of natural capital for cases of non-stationary output prices, technology and interest rates. For the former two cases (exogenous movements in prices and technology), constant consumption emerges under a strategy of investing to cover off economic...

[fre] Nous montrons que quand des firmes polluantes sont des concurrents à la Cournot, elles peuvent avoir une incitation à utiliser des permis de pollution comme moyen indirect de coordonner leur production. Si les firmes sont initialement identiques, les échanges de permis peuvent conduire...

We consider the effect of an increase in the risk from pollution. We show that in the case of a flow pollution, when the number of players is sufficiently large, the result of Bramoulle and Treich [<italic>Journal of the European Economic Association</italic>, 2009], showing that a marginal increase of risk in...

This paper explains how, in the context of incomplete coordination among all countries, unilateral policies that might at first sight seem pro-green could actually turn out to harm the global environment. The free-riding motives and the difficulty of reaching an effective international...

This paper reviews the game-theoretic literature on collaborative environmental management. It begins with a survey of static models of international environmental agreements (IEAs), comparing their underlying assumptions and their results. Extensions of the basic model to allow for both...

This paper provides general theorems about the control that maxi- mizes the mixed Bentham-Rawls (MBR) criterion for intergenerational justice, which was introduced in Alvarez-Cuadrado and Long (2009). We establish sufficient concavity conditions for a candidate trajectory to be optimal and...

We propose a new methodology exploring Markov perfect equilibrium strategies in differential games with regime switching. Specifically, we develop a general game with two players having two kinds of strategies. Players choose an action that inuences the evolution of a state variable, and decide...
