This study estimates the competitive effects of horizontal mergers in the French long-distance bus industry. We examine the two mergers that followed the 2015 Deregulation Act (the Macron Law); we use an exclusive and exhaustive dataset that covers eight consecutive quarters. We analyze the merger effects by comparing bus links that were affected by mergers with those that were unaffected; we use difference-in-differences estimations. We find that the two mergers are associated with price increases of about 13.5% immediately that then moderate to 5.3%; and with the frequency decreases from - 21.5 to - 25.7%; we observe no effects on load factors. These findings show evidence of short-run anticompetitive effects, while the mergers under study were not scrutinized by the French competition agency, as they were below the notification thresholds.

Conceived as a theory of competitive harm, self-preferencing has been at the core of recent European landmark cases (e.g., Google Android, Google Shopping). In the context of EU competition law, beyond the anticompetitive leveraging effect, self-preferencing may lead to vertical and horizontal exclusionary abuses, encourage exploitation abuses, and generate economic dependence abuses. In this paper, we aim at characterizing the various forms of self-preferencing, investigating platforms’ capacity and incentives to do so through their dual role, by shedding light on the economic assessment of these practices in an effects-based approach. We analyze the different options for remedies in this context, by insisting on their necessity, adequacy, and proportionality.

International audience; Notre propos est de fournir un éclairage économique sur certaines des dimensions liées au traitement concurrentiel des restrictions verticales. En effet, celles‑ci peuvent avoir des effets pro-concurrentiels qui sont susceptibles de conduire à un effet net positif sur le surplus du consommateur, notamment au travers d’un impact positif sur la qualité des produits et des services et sur les incitations à investir et à innover pour les firmes. Il s’agit d’interroger, selon une perspective d’économie industrielle, différentes dimensions de ces accords verticaux susceptibles de justifier une exemption par catégorie

International audience; In the European rail industry, to enable competition in the market, entrants should be granted access to a large set of complementary services, beyond access to the tracks. For an efficient and effective entry, temporary access to quasi-essential complementary assets like rolling stock, mechanical maintenance workshops, data, schedules, etc. is required. In the liberalized rail sector, several observed anticompetitive practices involve distorted access to these quasiessential facilities. Therefore, competition agencies must deal with litigation between the incumbent and new entrants. Most cases have been settled, resulting in commitments from the incumbent. We argue that such transitory and case-by-case remedies fail to produce favorable conditions for a secure and efficient entry. Thus, we propose to systematize such remedies through asymmetric and enduring ex-ante regulation.

GREDEG Working Paper No. 2020-56; During the 1920s, two different proposals of a regulated competition competed in the US. The first, inspired by trade associations, was advocated by Herbert Hoover. This approach echoes a managerialist view of a coordinated competition under state support. The second - promoted by Louis Brandeis - provides an alternative view of what a regulated competition should be: avoiding a ruinous competition through information exchange among small firms. From his involvement in the Wilson’s campaign team in 1912, to his dissent in the American Colum ruling of the US Supreme Court in 1923 and his position against the National Industrial Recovery Act in Schechter Poultry in 1935, we argue that Louis Brandeis was constant in his opposition to such a convergence between Big Business and Big Government. His intemporal coherence relies in his Jeffersonian approach advocating for a dispersion of economic powers for both efficiency and political purposes. At the opposite, both the trade associations’ movement and the NIRA experience pertain to a Hamiltonian perspective that is based on an equilibrium between the economic gains resulting from concentration or coordination and a strong political control.Available at: http://www.gredeg.cnrs.fr/working-papers/GREDEG-WP-2020-56.pdf

International audience; This article conducts a detailed analysis of the concept of economic dependence and exploitative abuse based on how their treatment in competition law and economics and their enforcement in European case law have evolved. Although the theoretical roots of these concepts lie in economic theory, these issues have been ignored or considered only scantily in the context of competition law enforcement. An effects-based approach should take these problems into account and could provide insights into how to portray the impacts of these abuses. We draw on two examples – from the agri-food industries and the digital economy – of relevant economic dependence issues. This paper highlights the existence of a paradox: although industrial organization models provide relevant tools to characterize these abuses, assess their effects, and devise remedies, it seems that they are seldom used by competition law enforcers.; Cet article analyse les concepts d’abus d’exploitation et de dépendance économique, non seulement sous le prisme de la jurisprudence concurrentielle européenne mais également sous celui de l’économie industrielle. Bien que les racines théoriques de ces concepts reposent sur la théorie économique, ils ont été ignorés ou peu pris en compte dans le contexte de l’application du droit de la concurrence. Une approche fondée sur les effets (effects-based) devrait tenir compte de ces pratiques et pourrait fournir des indications sur la façon d’analyser leurs impacts. Nous nous appuyons sur deux exemples tirés des industries agro-alimentaires et de l’économie numérique. Le présent article souligne l’existence d’un paradoxe : bien que les modèles d’organisation industrielle fournissent des outils pertinents pour caractériser ces abus, évaluer leurs effets et concevoir des mesures correctives, ils demeurent peu utilisés dans la pratique décisionnelle.

The duration of appellate court proceedings is an important determinant of the efficiency of a court system. We use data of 234 firm groups that participated in 63 cartels convicted by the European Commission between 2000 and 2012 to investigate the determinants of the duration of the subsequent one- or two-stage appeals process. We find that while the speed of the firststage appellate court decision depends on the court’s appeals-related workload, the complexity of the case, the degree of cooperation by the firms involved and the clarity of the applied rules and regulations, the second-stage appellate court proceedings appear to be largely unaffected by those drivers. We take our empirical results to derive conclusions for both firms that plan to file an appeal as well as public policy makers.

The opening up of the French long-distance bus industry is one of the outcomes of the Loi Macron . In this study, we build a unique data set of several representative bus routes and show that the effects of the liberalization have been encouraging in terms of fares, new entry, higher frequency, and higher quality. First, with regard to international routes that used to be under cabotage, we find that relaxing quantitative restrictions has led to the expected results on the Lyon–Torino and Paris–London routes. Second, with regard to domestic routes newly created from the Loi Macron , mostly all procompetitive expected variations in the variables have been observed, except for fares. Indeed, we show that bus operators used an initial aggressive pricing strategy to induce demand for the new services and then increased fares once customers became accustomed with the service.

International audience; The paper analyzes the interactions between trade and renewable energy policies based on the EU-China solar panel dispute which is the most significant antidumping (AD) complaint in Europe. We build a price competition duopoly model with differentiated products and intra-industry trade in photovoltaic (PV) equipment. We show that an optimal antidumping duty always increases with the feed-in tariff (FIT) program set in the home country. An appropriate antidumping duty - nullifying the dumping margin - decreases with the FIT program. We show that optimal FIT increases with the AD duty. Therefore, trade and renewable energy optimal policies may complement one another. Lastly, we introduce R\&D activities in the PV sector, and international spillovers. We show that R\&D makes the optimal FIT lower and increases the dumping margin. These effects are reinforced by technological spillovers.

En avril 2014, la Commission européenne a révisé ses Lignes directrices sur les aides d'Etat en matière d'énergie et d'environnement. Dans cet article, nous montrons comment l'analyse économique des effets des aides participe à la politique de la concurrence et propose un cadre rigoureux d'évaluation. Nous soulignons cependant que la manière dont les Lignes directrices présentent la nécessité des aides publiques est discutable. Deux logiques s'opposent en réalité, l'une distributive consistant à ne pas pénaliser les pollueurs domestiques vis-à-vis de la concurrence internationale, l'autre incitative dont l'objectif est de régler des externalités résiduelles. La Commission semble admettre trop rapidement les limites des politiques environnementales et ne met pas suffisamment en avant les externalités positives technologiques liées à l'innovation.
