The desirability relation was introduced by Isbell (1958) to qualitatively compare the a priori influence of voters in a simple game. In this paper, we extend this desirability relation to simple games with coalition structure. In these games, players organize themselves into a priori disjoint...

According to a given quota q, a candidate a is beaten by another candidate b if at least a proportion of q individuals prefer b to a. The q-Condorcet efficiency of a voting rule is the probability that the rule selects a q-Condorcet winner (q-CW), that is any candidate who is never beaten under...

It is commonly accepted that the multiplicity of equilibria is ubiquitous in preference aggregation games with any voting method. We prove that this multiplicity is greatly reduced under some mild restrictions over social preferences when each voter can vote for as many candidates as she wishes...

This paper proposes a new Bayesian approach for estimating, nonparametrically, functional parameters in econometric models that are characterized as the solution of a linear inverse problem. By using a Gaussian process prior distribution we propose the posterior mean as an estimator and prove...

At the end of 1960s, the U.S. divorce law underwent major changes and the divorce rate almost doubled in all of the states. This paper shows that changes in property division, alimony transfers,and child custody assignments account for a substantial share of the increase in the divorce...

In this paper, we aim to shed light on the relative contribution of the separation and job finding rates to French unemployment at business cycle frequencies by using administrative data on registered unemployment and labor force surveys. We first investigate the fluctuations in steady state...

The world is experiencing the development of new financial instruments to cope with natural catastrophes economic losses, this paper contributes to the forward movement of the discussion about the sustainability of one of these instruments known as non-life insurance linked securities. It shows...

Walras defines the goods of public interest as those of whom the need is smelt in all its extent only by the community or the State. The article studies the coherence of this definition, its implications and its relationships with the definitions which the economists had given or give public...

This paper extends on French data a previous finding on US data: employment growth has been more important in the lower and upper tail of the job quality distribution. The originality of the paper is to argue that the diffusion of ICT cannot explain alone the polarization at the lower tail of...

Dans le développement des théories de l’équilibre général, Hicks et Allais ont joué un rôle essentiel. On étudie ici les contributions qui furent les leurs respectivement dans Valeur et Capital (1939) et dans le Traité d’économie pure (1943). L’accent est mis sur trois points :...
