Competition and cost pass-through in differentiated oligopolies

Posted by D. Daniel Sokol

Iñaki Aguirre (Departamento de Fundamentos del Análisis Económico I, University of the Basque Country), Simon Cowan (Department of Economics, University of Oxford), and John Vickers (All Souls, University of Oxford) analyze Competition and cost pass-through in differentiated oligopolies.

ABSTRACT: This paper presents a general analysis of the effects of monopolistic third-degree price discrimination on welfare and output when all markets are served. Sufficient conditions — involving straightforward comparisons of the curvatures of the direct and inverse demand functions in the different markets — are presented for discrimination to have negative or positive effects on social welfare and output.

Horizontal mergers with synergies: first-price vs. profit-share auction

Posted by D. Daniel Sokol

Wei Ding (University of Bonn), Cuihong Fan (Shanghai University of Finance and Economics), Elmar G. Wolfstetter (Humboldt University of Berlin) address Horizontal mergers with synergies: first-price vs. profit-share auction.

ABSTRACT: We consider takeover bidding in a Cournot oligopoly when firms have private information concerning the synergy effect of merging with a takeover target. Two auction rules are considered: standard first-price and profit-share auctions, supplemented by entry fees. Since non-merged firms benefit from a merger if the synergies are low, bidders are subject to a positive externality. Nevertheless, pooling does not occur; and the profit-share auction is strictly more profitable than the first-price auction, regardless of whether firms observe the synergy parameter or only the winning bid before they play the oligopoly game.
