Dear colleagues, The Department of Economics cordially invites you to the WU Economics Research Seminar on Wednesday, November 22nd, with Michael Irlacher (JKU Linz) on "Multiproduct Firms, Horizontal Mergers, and International Trade" Abstract: This paper investigates the impact of mergers on the product mix of multiproduct firms. We open the black box of post-merger efficiency improvements to reveal a new margin of adjustment along the product dimension. Using detailed Danish data, we establish empirically that the combined domestic product scope of the acquirer and target falls after a merger, and sales become more concentrated towards the core product. Moreover, the acquirer exports more products to more destinations that are costly to serve. To rationalize these findings, we develop a model of mergers between oligopolistic firms, highlighting merger-induced within-firm adjustments that promote international trade.
