This paper develops a two-country general equilibrium model with endogenous growth where governements behave strategically in the provision of productive infrastructure. The public capitals enter both national and foreign production as an external input, and they are financed by a flat tax on...

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...

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...

Chichilnisky's criterion for sustainability has the merit to be, so far, the unique explicit, complete and continuous social welfare criterion that combines successfully the requirement of Weak Pareto with an instrumental notion of intergenerational equity (no dictatorship of the present and no...

This paper explores the dynamic properties of price-based policies in a model of competition between two jurisdictions. Jurisdictions invest over time in infrastructure to increase the quality of the environment, a global public good. They are identical in all respects but one: initial stocks of...

Two countries strategically invest in productive infrastructure within a general equilibrium model with endogenous growth. These public investments generate externalities. Dynamic analysis reveals that: (1) under constant returns, the two countries growth rates differ during the transition but...

This paper solves a second-best problem where a government has in particular to choose whether to tax financial inflows (capital con- trols) or not, and when. A multi-stage optimal control technique is used to this end. First, it is shown that it is optimal to switch in finite time from capital...

We consider a general control problem with two types of optimal regime switch. The first one concerns technological and/or institutional regimes indexed by a finite number of discrete parameter values, and the second features ecological-like regimes relying on given threshold values for given...
