The share of the foreign-born in OECD countries is increasing, and this article summarizes economics research on the effects of immigration in those nations. Four broad topics are addressed: labor market issues, fiscal questions, the political economy of immigration, and...

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...

Some recent empirical contributions have pointed out a significant negative impact of pollution on labor supply. These impacts have been largely ignored in the theoretical literature, which, instead, focused on the case of pollution effects on consumption demand. In this paper, we study the...

In this contribution, we analyze the economic consequences of immigration into France. France has a long tradition of hosting foreign populations. As in most developed countries, recent immigrants come from few countries (mainly from the Mediterranean Basin), are highly concentrated in a few...

Depuis quarante ans, les étudiants du supérieur sont de plus en plus nombreux à suivre une formation dans un pays étranger, et la concurrence entre pays d’accueil – principalement pays de l’OCDE – s’intensifie. Ces étudiants en mobilité constituent une cible privilégiée des...

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...

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...

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...
