When new technologies become available, it is not only essential that firms have the correct investment incentives, but often also that consumers make the proper usage decisions. This paper studies investment and usage in a shared ATM network. Because all banks coordinate their ATM investment...

How does an upstream firm determine the size of its distribution network, and what is the role of vertical restraints? To address these questions we develop and estimate two models of outlet entry, starting from the basic trade-off between market expansion and fixed costs. In the coordinated...

Regulators have recently shown an increased sensitivity to the issue of price squeezes, especially telecom regulators in European countries. This Paper analyses the relevance and the scope of price squeeze tests as proposed by practitioners and economists, taking the existing regulatory...

We study the determinants of the diffusion of mobile telecommunications services in the European Union in a logistic model of technology diffusion. We find that the transition from the analogue to the digital technology during the early nineties, and the corresponding increase in spectrum...

We consider the impact of a regulatory process forcing an incumbent telecom operator to make its local broadband network available to other companies (local loop unbundling, or LLU). Entrants are then able to upgrade their individual lines and offer Internet services directly to customers....

Exclusive dealing contracts between manufacturers and retailers force new entrants to set up their own costly dealer networks to enter the market. We ask whether such contracts may act as an entry barrier, and provide an empirical analysis of the European car market. We first estimate a demand...

We study the effects of the car scrapping subsidies in Europe during the financial crisis. We make use of a rich data set of all car models sold in nine European countries, observed at a monthly level during 2005-2011. We employ a difference-in-differences approach, exploiting the fact that...

Many countries organize their higher education system with limited or no ex ante admission standards. They instead rely more heavily on an ex post selection mechanism, based on the students' performance during higher education. We analyze how a system with ex post selection affects initial...

We exploit a natural experiment associated with a large merger in the Swedish market for analgesics (painkillers). We confront the predictions from a merger simulation study, as conducted during the investigation, with the actual merger effects over a two-year comparison window. The merger...

We shed new light on the performance of Berry, Levinsohn and Pakes' (1995) GMM estimator of the aggregate random coefficient logit model. Based on an extensive Monte Carlo study, we show that the use of Chamberlain's (1987) optimal instruments overcomes most of the problems that have recently...
