We consider an empirical model of worldwide airline alliances that we apply to a large set of companies for the period 19952000. Using observations at the network level, we estimate a cost, capacity, and demand system that accounts for cross-price elasticities. Our contribution consists in...

Une attention croissante est accordée aux enjeux économiques des services de transport en commun. Les questions relatives à la production et les coûts de transport, ainsi qu'aux effets de la réglementation et des politiques de subventions sur les performances de l'opérateur sont d'un...

Economic theory claims that contracts renegotiation prevents from reaching the informationally constrained efficient solution that could have been obtained under full commitment. Assessing the cost of renegotiation compared to the full commitment scenario still remains an open issue from an...

This article is aimed at deepening our understanding of the functioning of competition in the local bus transportation industry and to evaluate its effectiveness. It provides an overview of the competitive constraints that are at work in the industry as discussed in the economic literature, and...

We consider a framework of contractual interactions between public transport authorities and transport operators. We estimate simultaneously the contract choice by the authorities and the effect of regulation on the cost-reducing activity of the operators. We test whether the current regulatory...

The goal of this paper is to assess the impact on the performance of firms that participate in Research Joint Ventures (RJVs) funded by the Fifth European Framework Programme for Research and Technological Development (EU-FP5). A special emphasis is made on the User-friendly Information Society...

The renegotiation of regulatory contracts is known to prevent regulators from achieving the full commitment efficient outcome in dynamic contexts. However, assessing the cost of such renegotiation remains an open issue from an empirical viewpoint. To address this question, we fit a structural...
