The French labor market is divided between workers in permanent jobs and those who alternate fixed-term contracts with unemployment spells. Among other public policies aiming at reducing this duality, financial incentives could induce employers to lengthen contract duration or favor permanent...

The assimilation of immigrants and their children is a burning issue in France. Governments build a large part of their policies on the labor market. The public sector is reputed to integrate minorities better because of its entrance exams and pay-scales. In this paper, a comparison of the...

Discrimination models have diffivulties to study discrimination without assuming that prejudiced firms are more productive and results lead to workers' segregation. In this article, the model uses oligopsony and heterogeneity of workers' preferences to obtain a persistent discrimination. Firms...

This paper tests the impact of competition on the hiring process in the French retail sector. Following the Becker's theory, higher the competition, lower is discrimination. Using local Herfindhal-Hirschman indexes, a correspondence study ensures to observe how competition affects...

In this paper, we extend the problem of decentralization of Pareto optima in an economy with production externalities to the case where the production capacities upon which Pareto optimality is defined may differ from the aggregate of the firms expectations about their production possibilities....

This paper investigates the determinants of the shape of regional trade agreements (RTAs). Because the world is constituted by independent political entities, international trade flows take place in a system where property rights are unsecured and RTAs should be understood as regulation...

Since the GATT/WTO hinders tariffs manipulation, the Technical Barriers to Trade (TBT's) are a growing and appealing protection tool. The endogenous protection literature has shown that a government's taste for protection creates an incentive for lobbying. Since regulations at the origin of such...

Non-parametric methods have been empirically proved to be of great interest in the statistical literature in order to forecast stationary time series, but very few applications have been proposed in the econometrics literature. In this paper, our aim is to test whether non-parametric statistical...

In this paper, we discuss the parameter estimation for a k-factor generalized long memory process with conditionally heteroskedastic noise. Two estimation methods are proposed. The first method is based on the conditional distribution of the process and the second is obtained as an extension of...

Answering to an open question of Herings et al. (see [3]), one extends their fixed point theorem to mappings defined on convex compact subset of Rn, and not only polytopes. Such extension is important in non-cooperative game theory, where typical strategy sets are convex and compact. An...
