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...

Our paper contributes by bridging the gap between the (partial equilibrium) microsimulation and the computable general equilibrium (CGE) approaches, by making use of exact aggregation results from the discrete choice literature: heterogeneous individuals choosing within a set of discrete...

L'objectif de ce papier est d'analyser les impacts du vieillissement de la population italienne sur le système économique et en particulier sur le système de retraite afin d'évaluer l'efficacité des réformes mises en place durant les années 90 (réforme Amato en 1992 et réforme Dini en...

Most European countries have recently introduced pension system reforms to face the financial problem related to population ageing. Italy is not an exception. The reforms introduced during the Nineties (Amato Reform in 1992 and Dini Reform in 1995), even if they will produce a strong reduction...

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...

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...
