Immigration is often perceived as an instrument of adaptation for aging countries. In this paper, we evaluate, using a dynamic general equilibrium model, the contribution of migration policy in reducing the tax burden associated with the aging population in France. We show that the age and skill...

We study the Markov-perfect Nash equilibrium (MPNE) of a game between oil-importing countries, who seek to maintain the atmospheric carbon concentration under a given ceiling, and oil-exporting countries. The oil-importing countries set a carbon tax and the oil-exporting countries control the...

The Kyoto Protocol, which came in force in February 2005, allows countries to resort to «supplementary activities» consisting particularly in carbon sequestration in agricultural soils. Existing papers studying the optimal carbon sequestration recognize the importance of the temporality of...

[eng] We use a model based on the latest forecasts by the French Retirement Advisory Council (Conseil d’Orientation des Retraites : COR) at the moment when the study was carried out and a Bootstrap simulation of the rate of return on the financial portfolio of the French Pension Reserve Fund...

In this paper, we apply first and higher-order Euler discretizations to compare dynamic systems in discrete and continuous time. In addition, we stress the difference between backward and forward-looking approximations. Focussing on local bifurcations, we find that time representation is neutral...

This paper analyzes the determinants of the choice of location of international students. Building on the documented trends in international migration of students, we develop a small theoretical model allowing to identify the various factors associated to the attraction of migrants as well as...

In this paper, we expose the results of a voting experiment realised in 2007, during the French Presidential election. This experiment aimed at confronting the Single Transferable vote (SVT) procedure to two criteria : simplicity and the selection of a Condorcet-winner. Building on our electoral...

The potential economic impact of a selective migration policy are widely misunderstood. Three types of agents are affected : the migrants, the population of the leaving country and the natives of the host country. Based on a general equilibrium model with heterogeneous agents, this paper deals...
