always have incentives to merge, irrespective of cost uncertainty, while a merger without role redistribution is ex ante … there is uncertainty about the marginal costs of the newly merged firms. The authors consider that the merging firms decide … exact amount of cost efficiency/inefficiency that will result from the merger. Nevertheless, the key element of the model is …

when taking merger decisions. In practice, firms and competition authorities cannot know exact future efficiency gains …, prior to merger consummation. This paper analyzes horizontal mergers when the output decision-making process is sequential …. A key assumption is that mergers create uncertainty on productivity and informational asymmetry between firms. The paper …

required level of merger-specific cost reduction is larger if the fraction of multi-homing consumers is larger. These results …

downstream prices will rise as a result of the merger. This approach has gained acceptance.In this paper we present the results … of Monte Carlo simulations of a vertical merger for a simple setup with one upstream monopolist and two downstream firms …

We study the effects of a vertical merger in a setting with a single upstream supplier of a critical input and two … downstream customers announce their retail prices. We find that after the vertical merger, the merged firm will prefer to … its price. We preform Monte Carlo simulations about the competitive effects of the vertical merger for the cases of linear …

Common ownership fundamentally upsets the well-settled merger enforcement ecosystem. Not only it challenges basic … principles informing merger policy such as the presumed profitability of mergers for the merging firms and the merger …-specificity of potential efficiencies but also it works against implementing tools and presumptions in merger practice such as …
