We study the impact of socio-economic status on enrollment and study decisions in higher education. We use a discrete choice approach to distinguish between three channels. First, students from disadvantaged backgrounds may be more sensitive to the costs of education. Second, they may have lower...

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 study substitution from fixed-line to mobile voice access, and the role of various complementarities that may influence this process. We use rich survey data on 160,363 households from 27 EU countries during 2005-2012. We estimate a discrete choice model where households may choose one or...

We study a major new entry in the French mobile telecommunications market, followed by the introduction of fighting brands by the three incumbent firms. Using an empirical oligopoly model with differentiated products, we show that the incumbents' launch of the fighting brands can be rationalized...

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...

This mini-symposium takes stock of practical advances in competition damage evaluation. Combining perspectives from competition authorities, academics and practitioners respectively, it shows the existence of common principles and a set of widely accepted methods to calculate damages that may...

Empirical search cost estimates tend to increase in the size of the transaction, even ifsearch can be done conveniently online. To assess this pattern systematically, we conductan online search experiment in which we manipulate the price scale while keeping thephysical search effort for each...

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....

The roam-like-at-home regulation (RLAH) eliminated all mobile roaming surcharges to Eu-ropean consumers travelling within the European Economic Area (EEA). We measure the causal impact of the regulation on EEA roaming traffic, using the Rest of the World as a control group. We find large and...

Car prices in Europe are characterized by large and persistent differences across countries. The purpose of this paper is to document and explain this price dispersion. Using a panel data set extending from 1980 to 1993, we first demonstrate two main facts concerning car prices in Europe: (1)...
