This article presents an analysis of the behavior of countries defining their climate policies in an uncertain context. The analysis is made using the S-CWS model, a stochastic version of an integrated assessment growth model. The model includes a stochastic definition of the climate sensitivity...

In this paper we study the optimal growth path and its decentralization in a two-sector overlapping- generations model with pollution. One sector (power generation) is polluting and the other (final good) is not. Pollution is regulated by tradable emission permits. The issue is whether the...

That climate policies are costly is evident and therefore often creates major fears. But the alernative (no action) also has a cost. Mitigation costs and damages incurred depend on what the climate policies are, and in addition, they are substitutes. This brings climate policies naturally in the...

This paper studies the equilibrium dynamics of an overlapping generations model with capital, money and cash-in-advance constraints. At each date the economy can experience two different regimes. In the first one the cash-inadvance constraint is binding and money is a dominated asset. In the...

Using an updated version of the CWS model (introduced by Eyckmans and Tulkens in Resource and Energy Economics 2003), this paper intends to evaluate with numbers the respective merits of two competing notions of coalition stability in the standard global public goods model as customarily applied...

This note presents a model in which pension funds, by holding a significant share of capital assets, can exert a non competitive behavior on labor market. This leads to lower wages and higher capital returns, and can reduce capital accumulation and long-run welfare.

This paper develops a dynamic model wherein production generates pollution that is viewed as a public bad by consumers. There are two types of consumers : those who are altuist a la Barro-Becker and leave bequests to their children and those who are pure life-cyclers. Both types of consumers...

This paper addresses the issue of optimum population with two concerns : avoiding both the absolute repugnant solution that amounts to giving to an infinite number an infinitesimal amount and the marginal repugnant solution in which equilibrium consumption decresases with income. To avoid these...

The purpose of this paper is to provide a critical evaluation of theoretical models showing that shifting from pay-as-you-go to funded social security schemes can be made Pareto-improving. Further, it argues that what often makes a reform toward funded schemes attractive is a number of...
