In a two-tier industry with bottleneck upstream and two downstream firms producing vertically differentiated goods, we identify conditions under which the upstream supplier chooses exclusive or non-exclusive negotiations, or an English auction to sell its essential input. Auctioning off a...

We investigate the impact of vertical price restraints on the free-entry equilibrium and its welfare properties in a vertically related market where manufacturer-retailer hierarchies compete under asymmetric information. We compare the legal regimes of laissez-faire and ban on resale price...

The observability of managerial contract information in duopolies with strategic delegation has been an issue of controversial discussion. In a recent paper, Baik and Lee (2019) endogenize the decision to disclose the details of managerial contracts and show that in equilibrium, the owners of...

We consider an infinitely-repeated Bertrand game, in which prices are perfectly observed and each firm receives a privately-observed, i.i.d. cost shock in each period. We focus on symmetric perfect public equilibria (SPPE), wherein any "punishments" are borne equally by all firms. We identify a...

Collusion sustainability depends on firms' ability to impose sufficiently severe punishments in the event of deviation from the collusive rule. We extend results from the literature on optimal collusion by investigating the role of a limited liability constraint. We examine all situations in...

Using the coefficient of cooperation, we analyse the effect of cost asymmetries on collusive agreements when firms are able to coordinate on distinct output levels than the unrestricted joint profit maximization outcome. In this context, we first investigate the extent to which collusive...

The integration of algorithmic trading and reinforcement learning, known as AI-powered trading, has significantly impacted capital markets. This study utilizes a model of imperfect competition among informed speculators with asymmetric information to explore the implications of AI-powered...

We model non-binding retail-price recommendations (RPRs) as a communication device facilitating coordination in vertical supply relations. Assuming both repeated vertical trade and asymmetric information about production costs, we show that RPRs may be part of a relational contract,...
