This paper applies the Mean Fi eld Game approach pioneered by Lasry and Lions (2007) to the analysis of the researchers' academic productivity. It provides a theoretical motivation for the stability of the universaly observed Lotka's law. It shows that a remuneration scheme taking into account...

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...

Written on the occasion of the centenary of Louis Bachelier's 1900 PhD thesis “Théorie de la spéculation”, this paper puts Bachelier into a historical perspective. It explains his role as a pioneer in both mathematical finance and probability theory, and it also gives a careful account of...

This paper presents an application of new measures of research excellence, namely Hirsch's index (2005) and derived indexes. It gives a ranking of French departments of Economics, departments of Management and Business schools based on the quality of the academic environment offered by these...

Nous montrons dans cet article que l'approche mise en avant par P. Diamond et M. Yaari [1972] pour l'étude des propriétés des demandes d'actifs financiers est la seule qui soit compatible avec une définition correcte des effets de richesse. Nous en déduisons une méthode de compensation des...

We study a trading process for a pure exchange economy with overlapping generations. This process is based on the maximization, at each stage, of a collective benefit (or surplus). We show that this process converges to a Pareto-optimal allocation. This extends the second fundamental convergence...

Dans cette note, une démonstration rigoureuse établissant la validité des mesures de l'aversion au risque de Arrow-Pratt est explicitée et le lien avec l'approche de Kolm-Yaari est mis au jour.

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...
