  1. Reflective willingness to pay
    preferences for sustainable consumption in a consumer welfare analysis

    Our starting point is the following simple but potentially underappreciated observation: When assessing willingness to pay (WTP) for hedonic features of a product, the results of such measurement are influenced by the context in which the consumer makes her real or hypothetical choice or in which the questions to which she replies are set (such as in a contingent valuation analysis). This observation is of particular relevance when WTP regards sustainability, the "non-use value" of which does not derive from a direct (physical) sensation and where perceived benefits depend heavily on available information and deliberations. The recognition of such context sensitivity paves the way for a broader conception of consumer welfare (CW), and our proposed standard of "reflective WTP" may materially change the scope for private market initiatives with regards to sustainability, while keeping the analytical framework within the realm of the CW paradigm. In terms of practical implications, we argue, for instance, that actual purchasing decisions may prove insufficient to measure consumer appreciation of sustainability, as they may rather echo learnt but unreflected heuristics and may be subject to the specific shopping context, such as heavy price promotions. Also, while it may reflect current social norm, the latter may change considerably over time as more consumers adopt their behavior.

    A competition authority has an objective, which specifies what output profile firms need to produce as a function of production costs. These costs change over time and are only known by the firms. The objective is implementable if inequilibrium, the firms cannot collude on their reports to the competition authority.Assuming that the firms can only report prices and quantities, we characterize what objectives are one-shot and repeatedly implementable.We use this characterization to identify conditions when the competitive output is implementable. We extend the analysis to the cases when a buyer also knows the private information of firms and when the firms can supply hard evidence about their costs.

    We analyze a hub-and-spoke cartel in the Brazilian automotive fuel industry. Using the court documents and detailed data on the supply chain we uncover three mechanisms beyond information sharing used by wholesalers (hub) to help retailers (spokes) solve the obstacles of price coordination: vertical transfers across asymmetric spokes; subsidies during punishment; and cost stabilization. We argue that wholesalers benefited from the cartel by being the exclusive supplier during the scheme. We use the synthetic control approach to quantify how successful the cartel was in increasing markups. We find that not only retailers, but wholesalers benefited from the cartel.

    Dieser Beitrag fasst die ökonomischen Besonderheiten von Unterhaltungsmärkten zusammen und legt dabei einen besonderen Fokus auf Digitalisierungseffekte. Dabei werden die Aspekte Erfahrungsgüter und Qualität, Fixkostendegression & Güterheterogenität, Super-stareffekte, die Rolle (digitaler) Medien, sowie Preis- und Geschäftsmodelle diskutiert. Ein wesentliches Ergebnis der Betrachtung ist, dass Unterhaltungsmärkte im digitalen Zeitalter anfällig werden für typische Wettbewerbsbeschränkungen in digitalen Ökosystemen. Die Autoren unterstreichen diesen Befund mit einer Auswahl an relevanten und aktuellen Wettbewerbsproblemen und -fällen. Dabei zeigt sich, dass (i) die prowettbewerbliche Wirkung der Digitalisierung auf Medienmärkte fragil ist und des aktiven wettbewerbspolitischen Schutzes bedarf, (ii) nicht-horizontale Verflechtungen in digitalen Ökosystemen erhebliche Anreize zu behinderungswettbewerblichen Strategien wie Selbstbevorzugung, Monopolisierung und Raising Rivals Costs mit sich bringen und (iii) bisher funktionierende Abhilfemaßnahmen unter den Rahmenbedingungen digitalisierter Medien- und Unterhaltungsmärkte wohlfahrtssenkende Wirkungen entfalten können. Daher bedarf es einer Modernisierung der Wettbewerbsordnung für die Unterhaltungsindustrien.

    In this comprehensive review of ex-post merger studies price effects of horizontal transactions are evaluated. By combining and further analyzing the results of 52 retrospective studies on 82 mergers or merger-like transactions it can be shown that the industry alone is no strong indication for the direction of price-related merger effects. However, the "size" or "importance" of a transaction as well as market concentration pre-merger and change in concentration due to the transaction seem to have an impact on post-transaction price development.

    Many cartels are formed by individual managers of different firms, but not by firms as collectives. However, most of the literature in industrial economics neglects individuals' incentives to form cartels. Although oligopoly experiments reveal important insights on individuals acting as firms, they largely ignore individual heterogeneity, such as gender differences. We experimentally analyze gender differences in prisoner's dilemmas, where collusive behavior harms a passive third party. In a control treatment, no externality exists. To study the influence of social distance, we compare subjects' collusive behavior in a within-subjects setting. In the first game, subjects have no information on other players, whereas they are informed about personal characteristics in the second game. Results show that guilt-averse women are significantly less inclined to collude than men when collusion harms a third party. No gender difference can be found in the absence of a negative externality. Interestingly, we find that women are not sensitive to the decision context, i.e., even when social distance is small they hardly behave collusively when collusion harms a third party.

    This paper aims to analyze the interfaces between Brazilian Competition Law and the issue of access to medicines, with special focus on abuses of industrial property rights in their exclusionary and exploitative effects. The paper analyzes the case law of the Brazilian Administrative Council for Economic Defense (CADE) in the medicines sector and discusses the abuses aiming at the illegitimate imposition of non-existent or invalid intellectual property rights with anticompetitive purposes. It then addresses the abuses in the exercise of industrial property rights that are, in themselves, valid: exclusionary practices aimed at artificially raising barriers to entry, and exploitative practices, directly translated into the exercise of market power to the detriment of the consumer. The latter are turned into exploitative excessive prices, contractual degradations, quality or privacy degradations, as well as restrictions on supply such as hoarding/impediment to the exploitation of industrial property rights. The paper concludes that the prohibition of exploitative pricing under the current competition law is legally valid and effective, with certain methodological concerns in order to minimize the risk of wrongful convictions (such as the construction of “screening” tests of markets that are candidates for intervention). In view of such guidelines, the pharmaceutical industry appears to be an important candidate for antitrust attention, given the magnitude of the damages potentially derived from the non-intervention on the practice. Remedies in this area, importantly, should focus on identifying and solving the sector’s structural competitive problems. In the case of drugs subject to price regulation by the Drugs Market Regulation Chamber (CMED), the technical expertise of the competition authority may be of great value in competition advocacy, which is demonstrated in light of the recent discussions about extraordinary price adjustments due to competitive problems in a given market.

    In this paper we outline how a future change in consumers' willingness-to-pay can be accounted for in a consumer welfare effects analysis in antitrust. Key to our solution is the prediction of preferences of new consumers and changing preferences of existing consumers in the future. The dimension of time is inextricably linked with that of sustainability. Taking into account the welfare of future cohorts of consumers, concerns for sustainability can therefore be integrated into the consumer welfare paradigm to a greater extent. As we argue in this paper, it is expedient to consider changes in consumers' willingness-to-pay, in particular if society undergoes profound changes in such preferences, e.g., caused by an increase in generally available information on environmental effects of consumption, and a rising societal awareness about how consumption can have irreversible impacts on the environment. We offer suggestions on how to conceptionalize and operationalize the projection of such consumers' changing preferences in a "prospective welfare analysis". This increases the scope of the consumer welfare paradigm and can help to solve conceptual issues regarding the integration of sustainability into antitrust enforcement while keeping consumer surplus as a quantitative gauge.

    How does a firm’s market power in existing products affect its incentives to innovate? We explore this fundamental question using granular project-level and firm-level data from the pharmaceutical industry, focusing on a particular mechanism through which incumbent firms maintain their market power: “reverse payment” or “pay-for-delay” agreements to delay the market entry of competitors. We first show that when firms are unfettered in their use of “pay-for-delay” agreements, they reduce their innovation activities in response to the potential entry of direct competitors. We then examine a legal ruling that subjected these agreements to antitrust litigation, thereby reducing the incentive to enter them. After the ruling, incumbent firms increased their net innovation activities in response to competitive entry. These effects center on firms with products that are more directly affected by competition. However, at the product therapeutic area level, we find a reduction in innovation by new entrants after the ruling in response to increased competition. Overall, these results are consistent with firms having reduced incentives to innovate when they are able to maintain their market power, highlighting a specific channel through which this occurs

    This paper aims to analyze the interfaces between Brazilian Competition Law and the issue of access to medicines, with a special focus on abuse of industrial property rights and related exclusionary and exploitative effects. The paper analyzes the case law of Brazilian Administrative Council for Economic Defense (CADE) in the pharmaceutical sector and discusses abusive practices such as illegitimately imposing non-existent or invalid intellectual property rights with anticompetitive purposes. It then addresses abusive strategies in the exercise of industrial property rights which are, in essence, valid: i.e., exclusionary practices, aimed at artificially raising barriers to entry; and exploitative practices, directly translated as the exercise of market power to the detriment of the consumer. The latter ultimately result in exploitative excessive prices; contractual, quality or privacy degradation; and restrictions on supply, such as by hoarding/preventing the exploitation of industrial property rights. The paper concludes that the prohibition of exploitative pricing under the current competition law is legally valid and effective, with certain methodological concerns towards reducing the risk of wrongful convictions (for instance, by applying screening tests to determine the markets that are candidates for intervention). In view of such guidelines, the pharmaceutical industry appears to be an important candidate for antitrust attention, given the magnitude of the harm potentially derived from non-intervention against the practice. Remedies in this area, importantly, should focus on identifying and solving the sector's structural competitive problems. In the case of medicines subject to price regulation by the Drug Market Regulation Chamber (CMED), the technical expertise of the competition authority may be of great value in terms of competition advocacy, a fact that is demonstrated in light of recent discussions on extraordinary price adjustments because of competitive problems in certain markets.

    Traditional economic theory of collusion assumed that cartels are inherently unstable, and yet some manage to operate for years or even decades. While the literature has presented several determinants of cartel stability, the vast majority focuses on firms as entities, even though cartels are typically formed between individuals who need to develop structures that allow them to establish trust and ensure cooperation. We analyze 15 German cartels, focusing on the individual participants, the communication and internal structures within the cartels as well as their breakup. Our results indicate that cartel members are highly homogeneous and often rely on existing networks within the industry. Most impressively, only two of the 156 individuals involved in these 15 cartels were female, suggesting that gender also plays a role for cartel formation. We further identify various forms of communication and divisions of responsibilities and show that leniency programs are a powerful tool in breaking up cartels. Based on these results we discuss implications for competition policy and further research.

    Digital markets are at the forefront of competition policy. Over the past five years, antitrust regulators around the world have opened many investigations on digital platforms and issued and/or commissioned dozens of studies or expert reports that are focused on understanding the general competitive dynamics of markets such as online search, social media, e-commerce/marketplaces, and mobile operating systems. These studies and reports represent the forefront of our current understanding of how to adapt antitrust policy to the digital era. However, much of their wealth of knowledge is lost because these documents, which add up to thousands of pages of text, figures and tables, have been scattered around the websites of different competition agencies. This literature review consolidates the knowledge of twenty-two reports and studies on topics related to competition in digital markets issued by eighteen different authorities and expert panels around the world over the past five years. It addresses how these reports portray the general competitive dynamics of digital markets, the benefits generated by digitalization, the potential competitive shortcomings of digital markets in general and of well-defined relevant markets in particular, and the solutions that have been proposed to increase competition in the digital world. It also indicates areas where further academic research is needed. In doing so, it should serve as a guide to antitrust scholars, regulators, and practitioners, helping them understand the frontier of knowledge on the competitive dynamics of digital markets and the range of materials that are available for those who want to explore a certain topic more in-depth.
