Quel avenir pour le Fonds de réserve pour les retraites ?

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 (Fonds de Réserve pour les Retraites : FRR). Our results indicate that the FRR will cover at most 24 % of the expected deficit in 2020 and 14.9 % in 2040.

The optimal carbon sequestration in agricultural soils: Do the dynamics of the physical process matter?

This paper takes explicitly into account the temporality of sequestration. Its first contribution lies in the modelling of the asymmetry of the sequestration/de-sequestration process at a micro level, and of its consequences at a macro level.
