This paper aims at providing an original specification of French aggregate gross jobs flows during the period 1987 - 1996 for the manufacturing sector, based on the Markov-switching methodology. This approach allows us to analyze the different types of asymmetries documented in the literature...

Semi-definite programming (SDP) is of growing importance in various filed: system control, mechanics, combinatorial optimization, ... Usually, it is solved by interior point methods, which are elegant, efficicent and well-suited. However, they have limitations, particularly in large-scale or...

In the first place, we present a quasi fixed-point theorem for a correspondence defined on some infinite-dimensional locally convex topological vector space such that some variables have open lower sections and the other ones are upper semicontinuous. In the second place, we propose a direct...

We investigate the stability problem for a nonlinear autoregressive model with Markov switching. First we give conditions for the existence and the uniqueness of a stationary ergodic solution. The existence of moments of such a solution is then examined and we establish a strong law numbers for...

We extend the Mirrlees model of optimal income taxation to include the optimal provision of public goods and we analyze the problem of budget balancedness.

Une methodologie alternative aux modeles multicriteres fondes sur l'etude economique et financiere de la firme est proposee afin d'estimer le risque de defaut des entreprises et d'elaborer un indicateur du risque de faillite. Nous recourons a une methode de Gestion Actif - Passif d'estimation...
