Revisions incorporated into the Horizontal Merger Guidelines in 2010 claim that the Department of Justice and the Federal Trade Commission consider anticompetitive effects to product “variety” when evaluating mergers. The Guidelines do not, however, explain the methodology or tools that can...

This paper provides a full characterization of the price effects of horizontal mergers in the Cournot model with heterogeneous firms and constant returns to scale. We show that the price change brought about by a merger only depends on the smaller merging firm's share and the number of firms,...

This paper analyzes firms' choice between a merger and a strategic alliance in bundling their product with other complementary product. We consider a framework in which firms can improve profits only from product bundling. While mixed bundling is not profitable, pure bundling is because pure...

We study the effects of a vertical merger in a setting with a single upstream supplier of a critical input and two downstream customers which compete with each other. Initially, the upstream supplier first announces prices, then the two downstream customers announce their retail prices. We find...

Moresi and Salop (2013) have extended the “upward pricing pressure” approach used in analyzing horizontal mergers to the analysis of vertical mergers. They present test expressions called the vGUPPIu and vGUPPId to see if the upstream and downstream prices will rise as a result of the...

Merged firms are typically rather complex organisations. Accordingly, merger has a more profound effect on the structure of a market than simply reducing the number of competitors. We show that this may render horizontal mergers profitable and welfare-improving even if costs are linear. The...

In this article, we discuss the specific economic mechanisms underlying how mergers might affect the merging parties' incentives to innovate ex post. We then discuss these mechanisms in the context of several illustrative merger reviews and challenges brought by U.S. and EU antitrust authorities...

Im klassischen Beitrag von Salant, Switzer und Reynolds (1983) wird für symmetrische Unternehmungen gezeigt, daß bei Verfolgung einer Mengenpolitik Fusionen zur Einschränkung des Wettbewerbs nur dann für die beteiligten Unternehmungen lohnend sind, wenn wenigstens 80 % der Unternehmungen an...

We study the duopoly exit equilibrium in a multimarket environment with declining demand, and investigate the roles of strategic merger, agency cost, and collusion in a multimarket exit game.Cross-market spillovers with endogenous duration and the strategic merger of outside firms can serve as...
