Inthe seminar, Professor Yang introduces a paper that examines the price effects of two influential airline mergers taking place in China in 2010. They find that both mergers triggered significant price increases on routes affected by mergers. Shortly after the mergers, the price rise was larger for China Easternand Shanghai Airlines (overlapping network) than that of Air China and ShenzhenAirlines (complementary network). However, it was the other way around in the long run. They also find that high-speed rail had a significantly negativeimpact on airfare before early 2014. However, after early 2014, the entry ofhigh-speed rail was associated with airfare increases.During the seminar, participants and Professor Yang discussed the data, econometric model and the intuition behind the results.
