L'agglomération spatiale des firmes est un phénomène largement débattu en économie géographique. Cet article propose une nouvelle explication à ce phénomène : les entreprises mettent en avant la localisation comme un moyen de signaler un bien nouveau. Accepter la concurrence en se...

We develop a model that investigates how strategically interacting firms share a given set of spatially separated markets. We show that, for intermediate val-ues of transport costs, the spatial distribution of firms determines the structure of interregional trade, which in return influences this...

This paper studies changes in wage differentials accross education groups for full-time male workers in the French private sector, from 1976 to 2004. We apply quantile regressions to Mincer-type equations to disentangle between- and within-education group wage inequalities, and we describe...

La microfinance se développe progressivement dans la région du Moyen-Orient et d’Afrique du Nord (MENA) à travers des institutions de microfinance (IMF) très variées. L’objectif de la plupart de ces IMF est de concilier la performance sociale (PS) qui vise à réduire la pauvreté et la...

This paper analyses the pricing behaviour of Luxembourg firms based on survey evidence. Luxembourg firms typically have low market share, many competitors and longstanding customer relationships. Price discrimination is frequently applied. A majority of firms use price review rules that include...

This paper is dedicated to study the impact of economic freedom on economic growth. We use the methodology of panel data for the case of six Mediterranean developing countries. Our results show that the index of economic freedom in the process of development is not necessarily efficient in these...

While a new retirement pension reform is currently discussed in France, it is crucial to evaluate previous reforms. Up to now, no evaluation of the 2003 reform is available, particularly for civil servants. This article deals with the impact of this reform on the retirement behaviour of public...

What is a technologically advanced economy? We propose some theoretical elements showing how heterogeneity in the firms' innovation behaviours can be analysed and exploited in order to assess the technological performance of the economy. Three empirical applications using French data are derived...

A recurrent problem in economic studies based on survey data is to determine whether survey weights should be used or not. We show that weighted estimators are more robust than unweighted ones, but less accurate when unweighted estimators are consistent. In some circumstances, a compatibility...
