Abstract

[eng] This article deals with the empirical question of the relationship between price discrimination and concentration in intra-European routes. We estimate the impact of purchase restrictions on price in order to evaluate price discrimination. Ticket restrictions are used as proxies for price discrimination. We use data on ticket prices of all flights from Nice Airport (France) to European destinations. Our empirical analysis shows that concentration measured by the vahability of market shares decreases the sensitivity, in absolute value, of airline prices to purchase restrictions. Therefore, concentration leads to lower price discrimination. [fre] Cet article analyse la relation entre la concentration et la discrimination par les prix sur les routes aériennes en Europe. Nous estimons l'impact des restrictions sur les prix afin d'évaluer la discrimination. Les données de prix ont été collectées de manière séquentielle et portent sur l'ensemble des routes aériennes européennes desservies au départ de l'aéroport Nice Côte d'Azur. Notre analyse empirique montre que la concentration, mesurée par l'inégalité des parts de marchés des compagnies, diminue la sensibilité, en valeur absolue, des prix aux restrictions. Cela implique que la discrimination par les prix est plus faible sur les routes les plus concentrées.
