Interaction between schools and companies through Local Initiative Complementary Training Programmes in Post-secondary Education - Formation Complémentaire d'Initiative Locale - (FCIL), permits both the integration and adaptation to employment of young people who have received “standard”...

This paper examines a model of optimal growth where the aggregation of two separate well behaved and concave production technologies exhibits a basic non-convexity. Multiple equilibria prevail in an intermediate range of interest rate. However, we show that the optimal paths monotonically...

In this paper, we examine various methods in discrete time to extract and estimate the seasonality component of the CPI curve. One estimated, we show how to include this effect in the construction of the forward CPI curve. We then explain how to link it to a continuous time market model. Last...

In this paper, we propose a definition of Edgeworth equilibrium for a private ownership production economy with possibly infinitely many private goods and a finite number of pure public goods. We show that Edgeworth equilibria exist and can be decentralized as Lindahl-Foley equilibria, whatever...

We first present the concept of duality appearing in order theory, i.e. the notions of dual isomorphism and of Galois connection. Then we describe two fundamental dualities, the duality extension/intention associated with a binary relation between two sets, and the duality between implicational...

We consider the class of graphs containing no odd hole, no odd antihole and no configuration consisting of three paths between two nodes such that any two of the paths induce a hole and at least two of the paths are of length 2. This class generalizes claw-free Berge graphs and square-free Berge...

On the example of a pure-exchange financial economy with two periods, incomplete nominal-asset markets and differential information of the adverse selection's type, Cornet-De Boisdeffre (2002) introduced refined concepts of no-arbitrage prices and equilibria, which extended to the asymmetric...

This paper develops a model of an economy with clubs where individuals may belong to multiple clubs and where there may be ever increasing returns to club size. Clubs may be large, as large as the total agent set. The main condition required is that sufficient wealth can compensate for...

This study examines the theoretical and empirical link between trade integration, the density of activities and per capita income convergence within NAFTA members during the 1980-2000 period and within MERCOSUR partners from 1985 to 2000. We first build a two countries framework based on...

OECD countries displaying stringent employment protection legislation turn out to experience much less pronounced aggregate fluctuations. This paper uses this stylized fact to gauge the impact of employment protection on fluctuations costs. This analysis is run under a dynamic general...
