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 analyzes the welfare effects of private and unilateral disclosure of sensitive information in a sequential bargaining context. We consider a model where two sellers each propose a take-it-or-leave-it price for a homogeneous good to a single buyer. The buyer accepts or rejects the...

We study the propensity of independent algorithms to collude in repeated Cournot duopoly games. Specifically, we investigate the predictive power of different oligopoly and bargaining solutions regarding the effect of asymmetry between firms. We find that both consumers and firms can benefit...

We rationalize exclusive portfolio dealing in a novel three-period partial equilibrium framework populated by a representative, risk-neutral seller and a small number of ex ante identical broker-dealers. Endowed with independent, uncertain demand for a representative asset, the broker-dealers...

In this paper, we comment on the debate about guidelines for Art. 102 TFEU in the face of the challenges brought by digital ecosystems and abuse of dominance in related markets. We take the perspective of dynamic competition economics and derive four recommendations for the future enforcement of...

While the economic harm of cartels is caused by their price-increasing effect, sanctioning by courts rather targets at the underlying process of firms reaching a price-fixing agreement. This paper provides experimental evidence on the question whether such sanctioning meets the economic target,...

We study the feasibility and profitability of predation in a dynamic environment, using a parsimonious infinite-horizon, complete information setting in which an incumbent repeatedly faces potential entry. When a rival enters, the incumbent chooses whether to accommodate or predate it; the...

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...

Auctions are a prevalent way to exchange goods and are well-studied for the exchange of rivalrous goods, but are less studied for non-rivalrous goods. I examine an auction framework where the good sold can be used simultaneously by multiple bidders if their use does not conflict with others;...

We use a laboratory experiment to investigate whether statements from a governmental institution expressing concerns about price increases trigger such increases by facilitating tacit collusion. Such statements on market conduct are disclosed after an exogenous and unexpected upward cost shock....

Collusive agreements in the form of cartels among firms are complex structures. The involved firms need to agree on prices and sales quotas that are legally not enforceable. Market characteristics that foster cartels’ failure or success are widely examined. However, the interplay between the...
