Ce workshop a eu pour objectif de présenter des travaux de recherche avancés en économie industrielle autour de quatre questions de politique publique : les politiques de la concurrence, les politiques numériques, les politiques d’innovation et les politiques de propriété intellectuelle. A travers les différentes présentations, la discussion a porté sur l’intérêt de l’économie industrielle pour évaluer et repenser ces politiques publiques.

Session : IO and Antitrust Policy (Amphi Krier)

    « Winning Back Customers through Targeted offers : the Role of Customer Specific Information »
    In this paper, we provide a model for analyzing winback strategies. In our model, we consider a market composed of an incumbent and a potential entrant, and where price competition is analyzed for two periods. First, firms compete in prices. Second, …firms can contact consumers of their competitor and offer them specific discounts in order to incitate them to switch. We assume that the incumbent controls and has access to customer-specific information. This set of information facilitates price discrimination through targeted offers. We show that if the use of winback strategies does not affect entry (1) consumer surplus is higher when firms are allowed to use such strategies and (2) consumer surplus is higher if the incumbent is obliged to share its customer specific information only if this information does not allow too accurate price discriminatory offers in favor of competitors’ customers.
