Cartel birth and death dynamics: Empirical evidence

This paper examines how a gradual tightening of antitrust enforcement impacts cartels’ births and deaths. To avoid the inherent sample selection bias in prosecuted cartel studies, we use a unique dataset of Swedish legal cartels registered between 1946 and 1993. We compare estimates from a count model (considering only registered cartels) and a Hidden Markov Model (allowing for potentially unregistered cartels) to identify observed and hidden cartel dynamics. The count model suggests that strengthening antitrust enforcement has a deterrent effect, but the Hidden Markov Model suggests otherwise. Despite stricter competition laws and a credible threat of cartel prohibition, cartels continue to form, but do so undercover. Additionally, our results suggest that the strengthening of competition law has little impact on destabilizing existing cartels.     

The impact of external forces on cartel network dynamics: Direct research in the diamond industry

This paper describes the impact of external environmental forces on cartel networks. Using a case research approach, this report examines two leading business networks within one industry, over time. The results suggest that (a) bargaining power of intermediaries increases with the advent of new and powerful actors, (b) process activities that cartels previously controlled are being outsourced to new actors sometimes based in developing countries, (c) other actors are acquiring resources once dominated by a cartel, (d) external forces triggered by the illegal diamond trade, such as international regulatory constraints, no longer favour cartels like De Beers, and (e) over time, these and additional environment factors are forcing actors like De Beers who perform rigid process activities to become more flexible. For example, forces are moving cartels which relied previously on hand-picked intermediaries in highly controlled networks to market their products to adopt a flexible market-focused expansion of operations in retail contexts.     

Every cloud has a silver lining — Exploring the dark side of value co-creation in B2B service networks

This research explores the dark side of value co-creation (VCC) in B2B service networks. Whilst VCC is attracting a great deal of academic attention and a number of studies have highlighted the benefits of VCC, researchers often fail to consider the potentially negative consequences of VCC, especially in the context of business networks. This study explores the negative aspects associated with VCC in advertising service networks and identifies role conflicts and ambiguity, opportunism and power plays on the dark side of VCC. Tensions created by role conflicts during VCC interactions are highlighted. Also sharing of responsibilities during VCC can result in managers having a lack of clarity about what is expected of them, leading to role ambiguity and misunderstandings between firms. Managers engaging in VCC display weak-form opportunistic behaviors. These softer forms of opportunism are found to be tolerated and almost expected within long-term relationships. This research suggests that the exertion of power often shapes VCC activities within the advertising service network. Power plays are used as a means to mobilize appropriate resources and to influence network actors to adhere to value co-creation objectives. The presence of role conflicts, role ambiguity, opportunistic behaviors and power plays indicate that there is indeed a dark side to VCC that is currently omitted from existing VCC frameworks. A further contribution of our study is to highlight that a bright-dark dichotomy does not fully describe the complexity of VCC in B2B service networks and we show how the dark side may lead to positive outcomes.     

Penalizing cartels: The case for basing penalties on price overcharge

In this paper we set out the welfare economics based case for imposing cartel penalties on the cartel overcharge rather than on the more conventional bases of revenue or profits (illegal gains). To do this we undertake a systematic comparison of a penalty based on the cartel overcharge with three other penalty regimes: fixed penalties, penalties based on revenue, and penalties based on profits. Our analysis is the first to compare these regimes in terms of their impact on both (i) the prices charged by those cartels that do form and (ii) the number of stable cartels that form (deterrence). We show that the class of penalties based on profits is identical to the class of fixed penalties in all welfare-relevant respects. For the other three types of penalty we show that, for those cartels that do form, penalties based on the overcharge produce lower prices than those based on profit) while penalties based on revenue produce the highest prices. Further, in conjunction with the above result, our analysis of cartel stability (and thus deterrence), shows that penalties based on the overcharge out-perform those based on profits, which in turn out-perform those based on revenue in terms of their impact on each of the following welfare criteria: (a) average overcharge, (b) average consumer surplus, and (c) average total welfare.     

The darker side of sustainability: Tensions from sustainable business practices in business networks

While the current literature generally assumes that implementing sustainable business practices (SBPs) will lead to improved wellbeing and positive outcomes, relatively little research has explored the potential tensions and conflicts that SBPs may cause in multi-actor networks. To address this issue, we conduct a qualitative multiple case study in a regional business network, including interviews with 43 managers in 17 firms in different industries. The findings of this study identify four types of tensions (economic, structural, psychological, and behavioral) that tend to emerge when firms implement SBPs in networks, and illustrate how different stakeholders (implementers, suppliers, customers, other network partners) perceive them. Overall, this study contributes to the current literature by highlighting the underexplored “dark side” of sustainability, and illuminating how organizational decisions aiming at improving collective wellbeing can also lead to tensions and conflicts. For managers, this study offers insights into how to anticipate, manage and mitigate potential tensions that might arise in business networks when one stakeholder decides to implement a SBP.     

Critical events in time and space when cooperation turns into competition in business relationships

This study aims to improve our understanding of the processes of critical events in time and space that lead from cooperation to competition in dyadic business relationships. Within the business network approach there has recently been a call for research into both time and competition, and research combining both is novel. The study identifies and analyzes critical events in time, their connections with each other and the inner and outer space related to each event. The empirical study is based on four qualitative cases. The findings contribute to existing research by presenting several new perspectives on events and spaces, which improves our understanding of time and process in business networks. Business relationships may evolve from cooperation to competition through chronological events involving information sharing, sales-related and opportunistic activities. In space, these events mostly relate to the focal business relationships, the individual companies and third parties, such as customers.     

Social media-related tensions on business-to-business markets – Evidence from China

Previous research has established the benefits of using social media in support of engagement in business-to-business settings. Yet the study of problems that arise from social media use in business relationships remains limited. Utilizing a dyadic perspective, this study addresses the gap by focusing on tensions in buyer-supplier relationships that arise from social media use. Findings present three dualistic tensions: active engagement anticipated by suppliers versus passive monitoring practices of the buyers; increased transparency through business-to-business social media versus invisibility; as well as tensions between local versus international business-to-business social media engagement practices. The study draws on 52 semi-structured in-depth interviews with senior managers who work in relevant positions at manufacturing firms based in China. By identifying characteristic tensions pertaining to business-to-business social media, this study aims to contribute to research on the ‘dark side’ of business relationships as well as to literature on business-to-business social media engagement.     

The impact of the 2002 reform of the EU leniency program on cartel outcomes

The objective of this study is to empirically assess whether the 2002 reform of the EU leniency program, which brought the EU leniency policy much closer to the US policy, has increased the European Commission’s capability to destabilize cartels while making prosecution more efficient. More specifically, relying on a difference-in-difference approach, we estimate the impact of the 2002 reform on cartel duration, fines before and after applying leniency reductions and duration of investigation. We find that the 2002 reform decreased cartel duration by about 87 percent, but did not significantly affect the other outcome variables. Thus, our findings seem to suggest that the 2002 reform has improved the cartel-destabilizing effect of the EU leniency program, without enhancing however its effectiveness in prosecuting cartels.     

Fines and reputational sanctions: The case of cartels

In this article, we revive an old debate in the law and economics literature: the relative role of public and reputational sanctions in deterring misconduct. We propose an empirical framework, which accounts for public sanctions (in our case cartel fines) and a more direct measure of reputational sanctions, harnessing recent developments in opinion mining. We use the intensity and the sentiment of media exposure of misconduct as a measure of reputational effect and thus approximation of the reputational sanction. As a demonstration, we combine an event study approach, sentiment analysis, and econometric techniques on a sample of 339 listed cartel member firms, prosecuted by the European Commission between 1992 and 2015. Our results offer evidence that in the context of cartels, public and reputational sanctions act as substitutes: where there is a reputational penalty, increasing this penalty reduces the effect of the public sanction. One the other hand, in the absence of a reputational punishment, the effect of the cartel fine steps in.     

Dialectical tensions and path dependence in international joint venture evolution and termination

This paper identifies how dialectical tensions influence the conflicts in and unplanned terminations of international joint venture (IJV) relationships. The findings from case studies of two Finnish-Chinese JVs show how initial tensions and institutional imprints set the IJV processes in motion; how critical junctures influence perception of the IJV relationship and its evolution; and how a lack of efficient communication, interlinks between dialectical tensions, and insufficient movement of trust between cultural, organizational, and individual levels in the relationship lock in action patterns of confrontation which lead to the termination of the IJV. In essence, this study contributes to international business research by explaining the path-dependent nature of dialectical tensions in the evolution and survival of cross-cultural JVs.     

Market Power and Incentives to Form Research Consortia

It is well known that instability is a limit to the formation of cartels, and that some synergies are required to give cartel members an advantage over outsiders. In this paper, we explore theoretically the linkage between cost-reduction alliances (like research joint ventures) and the formation of cartels. The former have negative external impacts on outsiders, while the latter have positive external effects on outside (independent) competitors. We find that when the decisions to join both are made simultaneously the cartel can be profitable and stable for a smaller number of members than previously found for cartel formation alone by Salant et al. (1983, Quarterly Journal of Economics 98, 185–199). This result follows both for open membership and exclusive membership rules, and suggests a possible anticompetitive impact of research joint ventures.     

Managing tensions in coopetition

Tensions are natural in coopetitive business relationships that simultaneously involve cooperation and competition. The purpose of this study is to investigate how tensions are managed in coopetitive business relationships and examine the potential outcomes of the management of such tensions. The study will focus on various kinds of coopetitive relationships and how the management of the different tensions produces specific outcomes. The empirical study is based on comparative case study research on coopetitive business networks that features two different kinds of cases. The findings of the study contribute to coopetition research by identifying several new perspectives on tensions. Different levels of cooperation and competition in a coopetitive relationship as well as other underlying issues cannot alone determine tensions, but aspects such as the management of tensions are crucial. Most tensions are managed by using styles of competition and avoidance and result in mixed outcomes, which implies both positive and negative perceptions.     

What is dark about the dark-side of business relationships?

Over the last decade or so, the term ‘dark-side’ in referring to business relationships has been increasingly used in academic discourse. Despite such a growth in the number of studies, relatively little critique has been offered among scholars. The fact that effectively managing the dark side of business relationships has potentially greater influence of contributing to inter-organizational success beyond more focus on the positive side necessitates an urgent critique surrounding ‘what is dark about the dark side of business relationships?’ Thus, we aim to provide an overview relating to the ‘dark side’ of business relationships in a quest to generate greater debate on the subject.     

The Output Effects of Government Sponsored Cartels During the New Deal

This paper uses the National Industrial Recovery Act of 1933, which set up industry-wide cartels in the manufacturing sector of the US economy, to gain empirical insight into the current debate on the output effects of cartels. Recent theoretical studies have demonstrated ways in which cartels could expand, rather than reduce output as is traditionally thought. The New Deal cartel experiment does not support this 'efficient cartel' view. On the contrary, the legislation brought about a reduction in manufacturing output, as traditional cartel theory would predict.     

Flagging cartel participants with deep learning based on convolutional neural networks

Adding to the literature on the data-driven detection of bid-rigging cartels, we propose a novel approach based on deep learning (a subfield of artificial intelligence) that flags cartel participants based on their pairwise bidding interactions with other firms. More concisely, we combine a so-called convolutional neural network for image recognition with graphs that in a pairwise manner plot the normalized bids of some reference firm against the normalized bids of any other firms participating in the same tenders as the reference firm. Based on Japanese and Swiss procurement data, we construct such graphs for both collusive and competitive episodes (i.e when a bid-rigging cartel is or is not active) and we use a subset of graphs to train the neural network such that it learns distinguishing collusive from competitive bidding patterns. With the remaining graphs, we test the neural network’s out-of-sample performance in correctly classifying collusive and competitive bidding interactions. We obtain a very decent average accuracy of around 95% or slightly higher when either applying the method within Japanese, Swiss, or mixed data (in which Swiss and Japanese graphs are pooled). When using data from one country for training to test the trained model’s performance in the other country (i.e. transnationally), predictive performance decreases (likely due to institutional differences in procurement procedures across countries), but often remains satisfactorily high. All in all, the generally quite high accuracy of the convolutional neural network despite being trained in a rather small sample of a few 100 graphs points to a large potential of deep learning approaches for flagging and fighting bid-rigging cartels.     

Dark side of relationships: A tensions-based view

By drawing on the tensions-based view to depict the components of the dark side of relationships, this study presents a conceptual model explaining how the dark side of relationships can moderate the positive relationship between relationship quality and relationship function. The authors test the hypotheses via a mail survey involving 136 manufacturing firms. The results support the hypotheses, which posit that relationship quality is positively associated with relationship function. Moreover, the empirical results partially support the argument of the author that the influence of relationship quality on relationship function is strengthened or weakened when three relationship tensions (namely, behavioral, structural, and psychological tension) are balanced or imbalanced. Theoretical and managerial implications are extracted from this study, and potential future research directions.     

Value added reseller or value at risk: The dark side of relationships with VARs

This paper examines the dark side of using reseller networks to provide after-sales services. A proposal made by previous research studies on the use of brand-reseller relationships for management of value to be delivered remotely through reseller networks was reviewed. Technical inability, with a focus on the sales of resellers of information technology (IT) and information technology-enabled services/products (ITES), was highlighted as one of the major challenges faced by brands. Unsuccessful delivery and failure of VARs to provide after-sales services puts brand performance at risk and, as a consequence, negatively influences perceptions of other resellers concerning the brand. Thus a VAR's inability to support customers can discourage resellers from offering the brand to their customers. This dark side of network interdependence negatively affects the shared brand-reseller goal of value co-creation. Applying data collected from 334 resellers of technology brands in India, this research focuses on the current periphery of international branding literature by focusing on the dark side of manufacturer brand-reseller relationships. From the relationship management perspective, we contribute to the recognition of value-at-risk as the dark side of the brand-reseller relationship. Based on empirical findings, we propose a business model that will enable manufacturer brands to control the brand value perceived by their resellers, by monitoring the actions of their VARs.     

Tensions and ties in social media networks: Towards a model of understanding business relationship development and business performance enhancement through the use of LinkedIn

The era of social media networks has created significant opportunities for business relationship development yet there exists a paucity of research in this area. To address this, this paper identifies four key tensions within the current literature: relational versus transactional exchanges, emergent versus strategic social media network development, the pace of social media network formation versus the development of trust, and the notions of sharing and reciprocity versus competitive advantage. This study draws on the principles of netnography, incorporating data from 554 LinkedIn group interactions and 12 interviews with professionals in one global industry to provide insight into business relationship development stemming from one social media network. Significant contributions to theoretical and practical knowledge are made through the recognition of tensions in the literature, the application of the notion of Granovetter's ties to a contemporary context and the novel use of netnography. Furthermore, the resultant model conceptualises the use of social media networking in building networks and relationships which lead to new business and enhance business performance.     

Stable heterogeneous cartels

We define a nation of cartel stability which allows firms to perceive the impact of their actions on overall competitiveness in the market. We demonstrate that in an industry with linear demand and diverse linearly increasing marginal cost functions a stable cartel always exists. Furthermore, we examine uniqueness and size of such cartels as well as the impact of cost and demand conditions on their characteristics. In particular, we establish that the most efficient firms will be in the cartel while the less efficient ones will remain outside.
