Dans la phase des vagues d'innovations contemporaines, phase qu'on assimile à la troisième révolution industrielle ou encore à l'ère du numérique, les relations entre innovations, gains de productivité et emplois font l'objet de vives controverses, notamment aux Etats-Unis, pays phare en...

The paper identifies a necessary and sufficient condition for a deterministic local optimum to be locally improved upon by a stochastic deviation. When this condition is satisfied, a method to construct the stochastic allocations that increase the objective is provided. This technique is applied...

Earlier studies suggest that income taxation may affect not only labour supply but also domestic work. Here we investigate the impact of income taxation on partners' labour supply and housework, using data for France that taxes incomes of married couples jointly. We estimate a household utility...

This paper examines how import penetration affects firms' productivity growth taking into account the heterogeneity in firms' distance to the efficiency frontier and country differences in product market regulation.

L'existence d'une discrimination raciale à l'embauche sur le marché du travail est désormais largement documentée dans la plupart des économies occidentales. Si ce phénomène est confirmé par différentes études pour le marché du travail français, les causes et les sources de cette...

A game with precedence constraints is a TU game with restricted cooperation, where the set of feasible coalitions is a distributive lattice, hence generated by a partial order on the set of players. Its core may be unbounded, and the bounded core, which is the union of all bounded faces of the...

In the case of a large nuclear set (like the French set), nuclear production needs to be flexible to adjust to the predicted evolutions of the energy demmand. Consequently, the dominant position of nuclear in the national energy mix makes it responsible for the overall equilibrium of the...

We look at the optimal inter-temporal management of the fuel reservoir of nuclear units in a liberalized electricity market. We use the assumption that nuclear fuel works as a “reservoir” of energy due to the periodical shutdown of nuclear units to reload their fuel. In the medium-term, how...

This paper demonstates the existence of a finite set of equilibria in the case of the indeterminacy of linear rational expectations models. The number of equilibria corresponds to the number of ways to select n eigenvectors among a larger set of eigenvectors related to stable eigenvalues. A...

This article investigate the role of social influence for the expectation formation of economic agents. Using self-organizing Kohonen maps the repeated cross-section data set of the University of Michigan consumer survey is transformed into a pseudo panel allowing to monitor the expectation...
