Airline Market Power and Intertemporal Price Dispersion
研究了英国与爱尔兰之间航空市场中竞争程度与价格离散的关系，发现竞争会削弱航空公司价格歧视能力，但高峰时期此效应减弱。
This paper analyzes the empirical relationship between market structure and price dispersion in the airline markets connecting the U.K . and the R epublic of Ireland. Price dispersion is measured by the G ini coefficient, calculated using fares posted on the Internet at specific days before takeoff. We control for passengers' heterogeneity in their purpose of travel, as well as for such peak periods as C hristmas and E aster. Our finding of a negative correlation between competition and price dispersion suggests that competition is likely to hinder the airlines' ability to price discriminate, although this effect appears to be lessened in peak periods.
