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...

The Kyoto Protocol, which came into 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...

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...

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. Four variants, compared to a...
