On collusion sustainability and the elasticity of substitution

Escrihuela-Villar, Marc - 2026

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...

Collusion in the polluted river problem

Alvarez-Mozos, Mikel; Brink, René van den; … - 2026

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...

We measure how the contractual balance of power between franchisors and franchisees has shifted over 2009-2024 by analyzing a large corpus of Franchise Disclosure Documents and surveying over 300 franchisees. Coding more than 20 provisions across 4,500 chains, we find that franchisee autonomy...

An empirical inquiry into cartel overcharges and cartel fines including an assessment of the EU's guidelines on cartel fines and damages

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...

Public communication and collusion : new screening tools for competition authorities

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...

Detection of collusive networks in multistage auctions

Baránek, Bruno; Musolff, Leon; Titl, Vitezslav - 2025

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...

Sharing price announcements

Janssen, Maarten C. W.; Karamychev, Vladimir A. - 2025

We present a simple model where, before competing in prices, firms announce which prices they intend to choose. Deviating from these announcements involves a cost. We show that sharing pricing intentions results in prices being set above their competitive levels. All equilibria result in prices...
