Revisiting the Impact of Trade Liberalization and Mergers on the Malting Industry of North America

Neuere Einschätzungen zu den Auswirkungen von Handelsliberalisierung und Fusionen in der Mälzerei-Industrie Nordamerikas

Derek G. Brewin, Richard Gray and Giannis Karagiannis

This paper builds on the work of BUSCHENA and GRAY (1999) to look at the effects of mergers in the North American malting industry as ten firms in two separated markets merged into four firms in an integrated market. We explore the sensitivity of our results to the assumption of market power. We show that welfare gains from free trade are not generally lost but can face considerable redistribution under reasonable assumptions of market power.
Varying the rival reactions did not change the result that total economic surplus with four firms after NAFTA is greater than when there were ten firms but no trade. Mergers reduce the trade gains of malt consumers and barley producers in both countries and reduce the welfare losses of malting plants in the U.S. According to our estimates, the second wave of mergers may have led to a positive total welfare effect for malting plants in Canada if the oligopoly is exercising significant market power.

Dieses Papier befasst sich mit dem Handel und den Fusionen in der nordamerikanischen Mälzerei-Industrie, in der zehn Firmen in zwei getrennten Märkten zu vier Unternehmen in einem einzigen Markt integriert wurden. Wir zeigen, dass unter realistischen Annahmen von Marktmacht die Wohlfahrtsgewinne aus dem freien Handel zwar nicht völlig verloren gehen, aber zu einem erheblichen Teil umverteilt werden können. Fusionen reduzieren die Handelsgewinne von Malzaufkäufern und Gerste-Produzenten und reduzieren die Gesamtwohlfahrtsverluste der Mälzereien.
