Merger efficiency gains: Evidence from a large transport merger in france

Many industries are seeing an increase in concentration, leading to a discussion on the effectiveness of horizontal merger enforcement. The policy debate shows that one of the key arguments put forward when supporting potential mergers is the possibility of realization of merger efficiency gains, specifically in the transport industry. Yet, there exists little empirical evidence on the actual effects of realized mergers on cost efficiencies. We exploit a large and highly debated merger that took place in the French transport industry to evaluate whether a merger between two major transport groups may give rise to merger efficiency gains. We exploit the industry setting to employ a difference-in-differences methodology evaluating the effect of the merger on operating costs of merging transport groups. Our results show that, no matter the specification considered, we cannot conclude that the merger resulted in any merger specific efficiency gains for the merging parties. Our study relies on the use of several control groups and is robust to a great number of robustness checks as well as to the introduction of heterogeneous treatment effects, depending on the identity of the merging party, as well as the closeness of competition of local operators. Overall, our study contributes to a growing number of case studies undertaken by economists that can help determine whether horizontal merger policy is being properly enforced.     

Changing network pictures: Evidence from mergers and acquisitions

A merger or acquisition may cause dramatic changes in a business network, which in turn affect managerial cognition as well as managerial activities. We use the concepts of ‘network pictures’ and ‘networking’ to illustrate and analyse changes in managerial sense-making and networking activities following a merger or acquisition. The paper focuses on acquiring, acquired or merging parties and those companies with which they have direct customer relationships. Based on three case studies comprising seven acquisitions and one merger, we show that following a merger or acquisition managers may need to adapt their previous network pictures in a radical way; these adaptations are, however, not always realized as shifts in network pictures and adjustments in networking activities by all the managers involved. Whereas the merging parties' network pictures and networking activities are largely driven by their perception of customers' needs and developments, it is not certain that the merger or acquisition is enacted accordingly. The paper contributes to a clearer view on the conceptual interdependence of the constructs of network pictures and networking in multi-actor situations and thus it develops a network perspective on mergers and acquisitions.     

A New Perspective on Entry in Horizontal Merger Analysis

I analyze horizontal mergers in procurement settings in which sellers incur costs to participate. Considering existing sellers’ contest-level entry differs from antitrust authorities’ typical emphasis on new sellers’ market-level entry to counteract a merger’s anticompetitive harm. I show that profitable mergers can increase consumer and total surplus by inducing more and stronger contest-level entry by the merged seller, which echoes common claims from merging parties that their merger is beneficial because it creates a stronger competitor. This finding suggests caution by antitrust authorities: when contest-level entry costs matter, standard models that ignore those costs prescribe blocking procompetitive mergers.

     

Horizontal mergers and delegation

This paper shows that the profitability of merger in oligopoly is significantly enhanced if firms delegate the output decision to an agent and then motivate the latter using strategic rent shifting contracts. Two consequences of increased profitability are that the minimum market share that the merging parties require in order to merge profitably without efficiency gains, as well as the maximum market share that the merging parties can possess in order to guarantee that a profitable merger is welfare enhancing, are reduced. A third result is that delegation cannot reduce the set of endogenous mergers.     

Integrated market and nonmarket strategies: Political campaign contributions around merger and acquisition events in the energy sector

We examine how firms use political strategies to protect economic rents created by mergers and acquisitions against dissipation by regulators. In regulated industries, regulators can impose costly merger conditions, for instance consumer rate reductions in the utilities sector, thereby reducing shareholder gains. We investigate empirically whether and how firms use election campaign contributions to politicians as a method of influencing regulatory merger approvals. In a statistical analysis of campaign contributions by all electric utilities from 1998 to 2006, we find that utilities increased their contributions in the year before they announced a merger and that merging utilities increased their contributions more in states with greater political party competition. Our findings contribute to political strategy research by providing novel evidence that firms integrate market and nonmarket strategies. Copyright © 2013 John Wiley & Sons, Ltd.     

Ex post Merger Evaluation in the U.K. Retail Market for Books

This paper evaluates the price effects of the merger of two major U.K. book retailers. We use a dataset containing monthly scanner data on a sample of 200 books in 50 local markets for four years around the merger. We compare the price changes after the merger in shops located in areas where both chains were present before the merger and in areas where only one chain was present. We also investigate the country‐wide effect of the merger. We find that the merger did not result in any price increase either at the local or at the national level.     

Do Merger Efficiencies Always Mitigate Price Increases?

In a Cournot model with differentiated products, we demonstrate that merger efficiencies in the form of lower marginal costs for the merging firms (the insiders) lead to higher post‐merger prices under certain conditions. Specifically, when the degree of substitutability between the two insiders is not too high relative to that between an insider and an outsider, increased efficiencies may exert upward rather than downward pressure on the prices of the merging firms. Our results suggest that in cases where firms engage in quantity competition, antitrust authorities should not presume that efficiencies will necessarily mitigate the anticompetitive effects of the merger.     

Does competition increase quality? Evidence from the US airline industry

This paper studies the impact of competition on quality provision in the US airline industry exploiting a novel source of exogenous variation in competition. While mergers among market incumbents may stifle competition, a merger may increase the probability of entry if the merging airlines were not operating prior to merger in the market but each of them had presence at different route endpoints. We find non-merging incumbent airlines increase their flight frequency upon entry threat and accommodate entry of the newly merged airline by lowering flight frequency upon entry. While non-merging incumbents reduced arrival delays only upon entry of the newly merged airline, we find that incumbents decrease their cancelation rates and departure delays both upon merger announcement and entry of the newly merged airline. Our evidence suggests an increase in competition may increase consumer surplus, because non-merging incumbents increase quality and convenience, while keeping their prices unchanged.     

Retail Mergers and Food Prices: Evidence from France

This paper analyzes the impact of a merger in the French supermarket industry on food prices. Using consumer panel data, we compare the changes in prices for merging and rival firms in affected and comparison markets. We use a novel definition of affected markets when some firms have a local pricing strategy and others a more centralized pricing strategy. We find that prices increase significantly following the merger, and that the merging firms lose market shares. For the rivals, the price increases are larger in local markets, in which concentration increased and differentiation changed after the merger.     

Exploring the incremental merger value from multimarket and technology arguments

We address the question through which channels mergers create incremental value to merging firms and consider various product market and technological arguments. Based on the pairwise stable allocation concept, we estimate firms’ pair-specific (incremental) merger value functions. Our results show that technological arguments contribute to the majority of added merger value. We also find that market power arguments across multiple markets contribute to explaining incremental post-merger value. In contrast, multimarket strategic effects do not add merger value. Our estimated match values are aligned with the merging firms’ post-merger stock market performance.     

Early Settlement in European Merger Control

We analyse the determinants of early settlement between merging parties and the European Commission over remedies that remove concerns of anticompetitive effects. This extends the previously narrow range of econometric literature on early settlement. Consistent with the theory of early settlement, our results confirm the importance of delay costs and of uncertainty, measured by the complexity of the economic analysis required for each merger. We also find a non‐monotonic effect of agency resourcing, which raises questions about the Commission's efficiency in times of high case load. Econometrically, we select a sample of merger decisions in which the European Commission intervened due to concerns of anticompetitive effects, and our selection model provides estimates of the factors determining intervention by the Commission. Conclusions are drawn for public policy.     

Recent Developments at the CMA: 2018–2019

We discuss three important cases that the Competition and Markets Authority (CMA) has completed over the past year: The first two cases—the Experian/ClearScore merger and the Hotel Online Booking enforcement case—demonstrate our recent work on digital industries. We provide an overview of developments in this area and the CMA’s evolving approach to addressing such cases. The third case was a proposed merger between two of the UK’s largest grocery chains: Sainsbury’s and Asda. This proposed merger was ultimately prohibited by the CMA.

     

Merger Review by the Federal Communications Commission: Comcast–NBC Universal

The Communications Act of 1934 created a dual review process in which mergers in the communications industry are reviewed by the Federal Communications Commission (FCC) as well as the antitrust authorities. Commentators have criticized dual review not only as costly and redundant, but also as subject to substantive and procedural abuse. The process of clearing the 2011 Comcast–NBC Universal merger provides a useful case study to examine whether such concerns are justified. A review of the empirical context reveals that the FCC intervened even though the relevant markets were not structured in a way that would ordinarily raise anticompetitive concerns. In addition, the FCC was able to use differences between its review process and that used by the Justice Department to extract concessions from the merging parties that had nothing to do with the merger and which were more properly addressed through general rulemaking. Moreover, the use of voluntary commitments also allowed the FCC to avoid subjecting certain aspects of its decision to public comment and immunized it from having to offer a reasoned explanation or subjecting its decision to judicial review. The aftermath of the merger provides an opportunity to assess whether the FCC’s intervention yielded consumer benefits.     

Recent Developments at the CMA: 2017–2018

We describe three interesting cases that the UK Competition and Markets Authority (CMA) has dealt with over the past year: first, we discuss the merger of two online food ordering platforms—Just Eat and Hungryhouse—which required an assessment of competition in the presence of indirect network effects. Second, we discuss the vertical merger of a grocery retailer and wholesaler—Tesco and Booker—which posed the challenge of how to assess a firm’s incentives to foreclose its rivals when there are thousands of local markets. Finally, we discuss Open Banking, which lies at the heart of the package of remedies that came out of the CMA’s market investigation into personal banking, and sought to tackle issues of low customer engagement.     

Recent Developments at DG Competition: 2017/2018

The Directorate General for Competition at the European Commission enforces competition law in the areas of antitrust, merger control, and state aids. This year’s article provides first a general presentation of the role of the Chief Competition Economist’s team and surveys some of the main achievements of the Directorate General for Competition over 2017/2018. The article then reviews: the Google Search (Shopping) case, the role of price discrimination in state aid cases; and the use of counterfactuals in merger cases where alternative transactions might have occurred absent the merger.     

Mergers and product quality: Evidence from the airline industry

Retrospective studies of horizontal mergers have focused on their price effects, leaving the important question of how mergers affect product quality largely unanswered. This paper empirically investigates this issue for two recent airline mergers. Consistent with the theory that mergers facilitate coordination but diminish competitive pressure for quality improvement, we find that each merger is associated with a quality decrease (increase) in markets where the merging firms had (had no) pre-merger competition with each other, and the quality change can have a U-shaped relationship with pre-merger competition intensity. Consumer gains/losses associated with quality changes, which we monetize, are substantial.     

Merger externalities in oligopolistic markets

We evaluate the external effects of 183 large mergers at the market level by assessing the impact on the main competitors of the merging firms. Using synthetic control groups and difference in difference estimation, we find that the return on assets of rival firms increases significantly after a merger. The size of the effect varies strongly with market characteristics and the intensity of competition.     

Multimarket Contact and Intensity of Competition: Evidence from an Airline Merger

This paper examines the relationship between multimarket contact (MMC) and the intensity of competition. We take advantage of a recent merger, which altered the extent of MMC throughout the US airline industry, to understand the nature of MMC’s impact on the airlines’ frequency of service. Evidence that non-price effects of MMC are a part of the longer-term industry equilibrium is not robust. However, we observe that following the merger the market players started taking the degree of MMC into account in making their frequency decisions in line with the ‘mutual forbearance’ hypothesis; however, the effect showed signs of diminishing over time. Our results have implications for merger evaluation in industries where consolidation may lead to a higher extent of multimarket contact.     

Market Orientation and Innovativeness in Supply Chains: Supplier's Impact on Customer Satisfaction

As today's firms increasingly outsource their noncore activities, they not only have to manage their own resources and capabilities, but they are ever more dependent on the resources and capabilities of supplying firms to respond to customer needs. This paper explicitly examines whether and how firms and suppliers, who are both oriented to the same customer market, enable innovativeness in their supply chains and deliver value to their joint customer. We will call this customer of the focal firm the “end user.” The authors take a resource‐dependence perspective to hypothesize how suppliers' end‐user orientation and innovativeness influence downstream activities at the focal firm and end‐user satisfaction. The resource dependence theory looks typically beyond the boundaries of an individual firm for explaining firm success: firms need to satisfy customer demands to survive and depend on other parties such as their suppliers to achieve customer satisfaction. Accordingly, the research design focuses on three parties along a supply chain: the focal firm, a supplier, and a customer of the focal firm (end user). The results drawn from a survey of 88 matched chains suggest the following. First, customer satisfaction is driven by focal firms' innovativeness. A focal firm's innovativeness depends, on the one hand, on a focal firm's market orientation and, on the other hand, on its suppliers’ innovativeness. Second, no relationship could be established between a focal firm's market orientation and a supplier's end‐user orientation. Market orientation typically has within‐firm effects, while innovativeness has impact beyond the boundaries of the firm. These results suggest that firms create value for their customer through internal market orientation efforts and external suppliers' innovativeness.     

Recent Developments at DG Competition: 2016/2017

The Directorate General for Competition at the European Commission enforces competition law in the areas of antitrust, merger control, and state aids. This year’s article provides first a general presentation of the role of the Chief Competition Economist’s team and surveys the main achievements of the Directorate General for Competition over 2016/2017. The article then reviews the economic work undertaken in one merger case between Dow/DuPont, which raised specific issues related to innovation, as well as in an antitrust case on parity clauses related to Amazon e-books.
