In this paper we use the notion of distributable surplus, introduced by Allais (1943) and Luenberger (1992), to evaluate the capacity of European countries to repay their debts. In our analysis, we use Computable General Equilibrium (CGE) models to simulate di erent policies that can be...

In this paper we use the concept of distributable surplus, introduced by Allais (1943) and Luenberger (1992), to evaluate the capacity of European countries to repay their debts. We first show that the surplus generated between 2005 and 2009 was not sufficient to cover the 2009 deficit for...

In this paper, we study in the framework of the RDEU model, on one hand the bid-ask spread, and on the other hand the disparity between the buying price and the selling price of a random variable. We show that there is no fundamental difference between the results obtained in the framework of...

The h-index is an index recently proposed by Hirsch (2005) to measure scientific achievement by individual scholars. It is a compound measure of publications and citations. We show the robustness of this index. This means that h-index increases with both the number of publications and the number...

The benefit function, introduced by Luenberger, provides a tool for well-defined cardinal comparisons of different bundles of goods. It also allows to study in an orignal way optimal consumers and firms choices, Pareto-optimality etc... In this note we prove that the benefit function is...
