We investigate the effect of a vertical merger on downstream firms' ability to collude in a repeated game framework. We show that a vertical merger has two main effects. On the one hand, it increases the total collusive profits, increasing the stakes of collusion. On the other hand, it creates...

We investigate the effects of passive backward acquisitions in their efficient upstream supplier on downstream firms' ability to collude in a dynamic game of price competition with homogeneous goods. We find that passive backward acquisitions impede downstream collusion. The main driver of our...

This paper investigates the effects on tacit collusion of increased market transparency on the consumer side of a market in a differentiated Hotelling duopoly. Increasing market transparency increases the benefits to a firm from underbutting the collusive price. It also decreases the punishment...

We investigate the effect of a vertical merger on downstream firms' ability to collude in a repeated game framework. We show that a vertical merger has two main effects. On the one hand, it increases the total collusive profits, increasing the stakes of collusion. On the other hand, it creates...

Cartels may be exempted from competition law if they sufficiently promote sustainability objectives. To qualify, the collusive agreement should not fully eliminate competition. We study how remaining and fringe competition affect incentives to produce more sustainably under semi-collusion in an...

This paper considers a general symmetric quantity-setting oligopoly where the "coefficient of cooperation" defined by Cyert and DeGroot (An Analysis of Cooperation and Learning in a Duopoly Context, 1973) is interpreted as the parameter indicating severity of competition. It is obtained that...

The deregulation of the telecommunications industry has resulted in a variety of industry structures which have been created in hopes of increasing competition. One example is the licensing of cellular telephone services in the United States where the FCC created duopolies in which two firms...

We analyze strategic leaks due to spying out a rival’s bid in a first-price auction. Such leaks induce sequential bidding, complicated by the fact that the spy may be a counterspy who serves the interests of the spied at bidder and reports strategically distorted information. This ambiguity...

This paper analyses the dynamics of a Cournot duopoly under cross-ownership participation when players have heterogeneous, i.e. bounded rational and naïve, expectations. We find that when the shareholder that owns firm also holds a percentage of firm , the parametric stability region of the...
