In this note, we consider a generalized T−stage Stackelberg oligopoly. We provide a proof and an interpretation that under the two necessary and sufficient conditions of linear aggregate demand and identical constant marginal costs, followers do not matter for leaders. Leaders act as rational...

In this paper, we investigate the extent of the effects of children and child-related time out of the labor market on the gender wage gap in France, with special attention to its impact on the accumulation and composition of human capital. Measuring this impact requires detailed information on...

Following the adoption of information and communication technologies (ICT), firms are likely to face increasing skill requirements. They may react either by training or hiring the new skills, or by a combination of both. We first show that ICT are indeed skill biased and we then assess the...

This paper investigates the relationship between bank competition and credit procyclicality for 17 OECD countries on the 1986-2009 period. We account for heterogeneity among countries in terms of bank competition through the use of a hierarchical clustering methodology. We then estimate panel...

This paper takes a minimax regression approach to incorporate aversion to parameter uncertainty into the mean-variance model. The uncertainty-averse minimax mean-variance portfolio is obtained by minimizing with respect to the unknown weights the upper bound of the usual quadratic risk function...

The Law on Economic Modernization of 4 August 2008 introduced a new form of individual entrepreneur, the auto-entrepreneur, the goal being to enhance the competitiveness of the French economy by promoting the entrepreneurial spirit.

The aim of this paper is to determine if OPEC acts as a cartel by testing whether the production decisions of the different countries are coordinated and if they have an influence on oil prices. Relying on cointegration and causality tests in both time series and panel settings, our findings...

Urban riots, such as in France in 2005, have drawn attention on the spatial determinants of social discontent. We provide evidence on the pervasive collective perception of a dramatic increase of the well-being disparities within the Paris Region during the decade preceding the 2005 riots. We...

In this article we focus on the private practitioner's voluntary choices of the pricing practices (free care and high fee care) to understand the practitioners' economic behavior. We use an unbalanced panel data comprising 7896 self-employed physicians who were observed over the 1980-2000...

This paper deals with the optimal enforcement of the competition law between the merger and anti-cartel policies. We examine the interaction of these two branches of the competition policy given the budget constraint of the competition agency and taking into account the ensuing incentives for...
