Market Share Instability in Commercial Airline Markets and the Impact of Deregulation
研究了美国航空业放松管制头两年内，市场份额波动是否反映了竞争（包括价格和非价格竞争）的实际加剧，并提供了一个分析框架来评估监管改革对其他行业竞争的影响。
While the degree of rivalry in a market is often concealed and therefore difficult to observe directly, various measures of market-share variation have been used in the literature as an indicat or of behavior. Using a similar measure, the primary task of this stu dy is to estimate the degree to which rivalry (both price and nonpric e) had actually increased during the first two years of deregulation. The paper also provides an analytical framework which may be used to assess the impact of regulatory reform on rivalry in other industrie s. Copyright 1988 by Blackwell Publishing Ltd.
