Integrating Trade Theory with Industrial Organization
(based on the paper 'Cross-Border Mergers as Instruments of
Comparative Advantage')
wiiw, 26 February 2004, 1 p.m.
A two-country
model of oligopoly in general equilibrium is used to show how
changes in market structure accompany the process of trade liberalisation,
suggesting a resolution to a long-standing puzzle in merger
theory. The model predicts that bilateral mergers in which low-cost
firms buy out higher-cost foreign rivals are profitable under
Cournot competition. The model implies that trade liberalisation
can trigger international merger waves, in the process encouraging
countries to specialise and trade more in accordance with comparative
advantage.
