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...

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

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...

We study the effect of entry on costs and competition in the Portuguese mobile telephony industry.\ We construct and estimate a model that includes demand, network, and cost equations. The latter accounts for inefficiency and cost reducing effort. Our results suggest that the entry of a third...

This article proposes to evaluate empirically the consequences of the rent-seeking behavior of football clubs on their costs. The empirical work entails estimating a football wage, result, and demand system with data on clubs competing in the first and second Spanish leagues during the 1996-2003...

This article is an attempt to shed light on the specification and identification of inefficiency in stochastic frontiers. We consider the case of a regulated firm or industry. Applying a simple principal-agent framework that accounts for informational asymmetries to this context, we derive the...

This paper is aimed at assessing the empirical relevance of the new theory of regulation. It relies on a principal-agent framework for studying the regulatory schemes used in the French urban transport industry. Taking the current regulatory schemes as given, the model of supply and demand...
