Price Discrimination in the Airline Market: The Effect of Market Concentration
检验了航空市场竞争加剧是否导致更多价格歧视，发现周六过夜和提前购票等限制带来的折扣在竞争更激烈的航线上更大。
We test the hypothesis that price discrimination increases with competition in the airline market. Using a large cross section of tickets offered by several carriers on various routes, we approximate price discrimination with marginal implicit prices of ticket restrictions that carriers typically use to price discriminate: Saturday-night stayover re-quirements and advanced-purchase discounts. We find that the restrictions are associated with lower airfares, but that the discounts are smaller on routes with higher market concentration. The results suggest that price dispersion attributed to ticket restrictions increases as markets becomemore competitive. 2000 by the President and Fellows of Harvard College and the Massachusetts Institute of Technology
