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...

Competition in some product markets takes the form of a contest. If some firms cooperate in such markets, they must decide how to allocate effort on each of their products and whether to reduce the number of their products in the competition. We show how this decision depends on the convexity...

Merged firms are typically rather complex organizations. Accordingly, me rger 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...

Standard welfare analysis of horizontal mergers usually refers to two effects: the anticompetitive market power effect reduces welfare by enabling firms to charge prices above marginal costs, whereas the procompetitive efficiency effect increases welfare by reducing the costs of production...

We demonstrate that the popular Farrell-Shapiro-framework (FSF) for the analysis of mergers in oligopolies relies regarding its policy conclusions sensitively on the assumption that rational agents will only propose privately profitable mergers. If this assumption held, a positive external...

We study mergers in a market where N firms sell a homogeneous good and consumers search sequentially to discover prices. The main motivation for such an analysis is that mergers generally affect market prices and thereby, in a search environment, the search behavior of consumers. Endogenous...

By combining two large data sets (on international trade flows and cross-border mergers and acquisitions – M&As), we test two implications of Neary’s (2003, 2007) general oligopolistic equilibrium (GOLE) model (incorporating strategic interaction between firms in a general equilibrium...

This paper studies the incentives to merge in a Bertrand competition model where firms sell differentiatedproducts and consumers search for satisfactory deals. In the pre-merger symmetricequilibrium, the probability that a firm is the next one to be visited by a consumer is equal acrossfirms not...

Mergers and acquisitions (M&A) is the dominant form of Foreign Direct Investment (FDI), but has received but scarce attention in the theory literature on trade and investment. This paper highlights how the international pattern of ownership of productive assets may depend on features of trade...

This paper evaluates the welfare consequences of the failing firm doctrine in the EU and US merger laws. I combine an oligopoly model with an 'endogenous valuations' auction model. Thereby, I take into account that, in an oligopoly, a firm's willingness to pay for the assets depends on the...
