Nous exploitons une enquête de la statistique publique (COI2006) auprès d'un échantillon représentatif d'entreprises privées et auprès d'un échantillon aléatoire de salariés de ces entreprises dont une sélection d'une trentaine est réinterrogée lors d'entretiens qualitatifs deux ans...

This paper proves the existence of competitive equilibrium in a single-sector dynamic economy with heterogeneous agents, elastic labor supply and complete assets markets. The method of proof relies on some recent results concerning the existence of Lagrange multipliers in in nite dimensional...

The paper concerns a dynamic model of influence in which agents have to make a yes-no decision. Each agent has an initial opinion, which he may change during different phases of interaction, due to mutual influence among agents. The influence mechanism is assumed to be stochastic and to follow a...

Cet article présente un cas particulier de régression non fondée, lorsqu'une variable dépendante a un coefficient de corrélation simple proche de zéro avec deux autres variables, qui sont en revanche très corrélées entre elles. Dans ce type de régressions, les paramètres mesurant la...

Applying regressions on a sample of 18 OECD countries from 1970 to 2009 using new indicators, we find that right-wing governments liberalize more the financial sector that left-wing governments. We show that if a left-wing government accepts to liberalize the financial sector, an increase of...

For an exchange economy, under assumptions which did not bring about the existence of quasiequilibrium with dividends as yet, we prove the nonemptiness of the fuzzy rejective core. Then, via Konovalov (1998, 2005)'s equivalence result, we solve the equilibrium (with dividends) existence problem....

Nous étudions un duopole sur un marché où les produits sont différenciés horizontalement. Les firmes se font concurrence en catalogue dans le sens où elles choisissent simultanément un produit et un prix. Nous montrons alors qu'il n'existe pas d'équilibre de Nash en stratégie pure en...

This paper investigates the relevance of financial and economic variables as determinants of firm default. Our analysis cover a large sample of medium-sized limited liability firms. Since default might lead, through bankruptcy or radical restructuring, to firm's exit, our work also relates with...

There are many apparent similarities between the current political and economic situations of France and Italy. The mainstream view is that at least part of the neo-liberal strategy could be a solution to the economic problems of both variants of the European model of capitalism. However, the...
