We analyze the relationship between collusion sustainability in an infinitely repeated game using trigger strategies and the elasticity of substitution. To this end, we adopt a demand function with constant elasticity of substitution between the differentiated goods. Since our model exhibits a...

We study the effects of collusion in the polluted river problem. In this model, agents along a river network have to share the costs of cleaning the entire river. We define a collusion neutrality property which requires that, if all agents upstream of a given point agree to collude and act as...

Algorithms pose interesting challenges to competition law, particularly discussing which practices involving this fast-paced technologies may or should be caught under Article 101 of the Treaty on the Functioning of the European Union ("TFEU"). As AI-driven pricing algorithms become increasingly...

Competition authorities impose substantial penalties on firms engaging in illegal pricefixing. We examine how basing cartel fines on either revenue, profit, or price overcharge influences cartel and market prices, as well as cartel incidence and stability. In an infinitely repeated Bertrand...

This paper investigates partial cartels, which laboratory studies have neglected despite their empirical prevalence. We conduct two laboratory experiments to understand how they function compared to all-inclusive cartels and respond to antitrust policies. First, we compare partial cartel...

Competition authorities increasingly rely on economic screening tools to identify markets where firms deviate from competitive norms. Traditional screening methods assume that collusion occurs through secret agreements. However, recent research highlights that firms can use public announcements...

We develop a method for detecting cartels in multistage auctions. Our approach allows a firm to be collusive when facing members of its cartel yet competitive when facing others. Intuitively, as initial bids are shaded, close initial bids not only imply similar costs but also provide an...

This paper explores algorithmic collusion from both legal and economic perspectives, underscoring the increasing influence of algorithms in firms’ market decisions and their potential to facilitate anti-competitive behaviour. By employing bandit algorithms as a model—typically used in...

Using a sample of listed Chinese firms from 2007 to 2020, we investigate the governance implications of cross-ownership in corporate bond markets. We find that cross-ownership significantly reduces bond issuance spreads, suggesting that synergistic governance effects outweigh potential collusion...

It is well-known that failing to achieve key organizational goals may pressure managers to commit fraud, but can it be a facilitating factor in cartel formation as well? The purpose of this study is to understand if firms known to have been in a cartel were under financial stress in the period...

This paper examines how the Brazilian ready-mix concrete cartel expanded through mergers and acquisitions. Specifically, we investigate whether cartel firms strategically acquired non-aligned competitors to optimize market dominance, eliminate competition and sustain collusive behavior.Using...

Utilizing Connor's International Cartel Database and employing difference-in-differences methodology, we find that market concentration, the number of buyers and cartel duration have significant impacts on cartel overcharges. We also find that the European Commission's 2006 guidelines on the...

This study analyzes the impact of patent rights on duopolistic competition with price leadership. The willingness of companies with significant patent rights to form a cartel was assessed. The main aim of the analysis was to determine the role of patents in maintaining the stability of the...

Utilizing Connor's International Cartel Database and employing difference-in-differences methodology, we find that market concentration, the number of buyers and cartel duration have significant impacts on cartel overcharges. We also find that the European Commission's 2006 guidelines on the...

There are many evidences which prove that cartels’ price leads to an economic inefficiency, due to the reduced consumers welfare. Antitrust authorities have set up different ways to defeat and prevent collusive agreements, but as widely showed by the literature, deterring collusion may have...

A bonus on the fine in response to the defendant running a corporate compliance program is superfluous because working leniency programs provide all the incentives necessary to implement efficient compliance. Others opposed to such a bonus argue that unreduced fines are sufficient to incentivize...

In this paper, we aim to investigate the collusive stability in the presence of network externalities among firms with relative performance in the firm's objective functions. We demonstrate that collusive stability is increasing (decreasing) in the degree of relative performance, product...
