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 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...

We estimate the spillovers on firm profitability and market shares in oligopolistic markets through the transition from an n to an n-1 player oligopoly after a merger in the industry. Competitors are identified via the European Commission s market investigations and our methodology allows us to...

We study the merger paradox, a relative of Harsanyi's bargaining paradox, in an experiment. We examine bilateral mergers in experimental Cournot markets with initially three or four firms. Standard Cournot-Nash equilibrium predicts total outputs well. However, merged firms produce significantly...

This is a survey of the economic principles that underlie antitrust law and how those principles relate to competition policy. We address four core subject areas: market power, collusion, mergers between competitors, and monopolization. In each area, we select the most relevant portions of...

We quantify externalities on profitability and market shares of competing firms in oligopolistic markets through the transition from an n to an n-1 player oligopoly after a merger. Competitors are identified via the European Commission's market investigations and our methodology allows us to...

The impact that competition exerts on the incentives of firms to pass through reductions in their marginal costs is an important consideration in assessing the performance of alternate market structures. This paper examines the role of product differentiation on firm-specific and industry-wide...

Turkish Banking Act exempts certain bank mergers from the Turkish merger control regime. With this legislation, a large number of the potential bank merger are exempted from obtaining the permission from the Turkish Competition Authority. Turkish Competition Authority and international...

We analyze the effects of a merger between two competitors in a Bertrand-Edgeworth model. The merger has no effect on equilibrium prices if a pure strategy equilibrium prevails both before and after the merger. Otherwise, the merger leads to higher prices. In the case where a mixed strategy...

This paper analyzes the effects of mergers and acquisitions on the markups of non-merging rival firms across a broad set of industries. We exploit expert market definitions from the European Commission's merger decisions to identify relevant competitors in narrowly defined product markets....
