March 2001An Empirical Investigation of the Competitive Effects of Domestic Airline Alliances
with Dennis W. Carlton, Lynette R. Neumann: w8197
In this paper, we investigate empirically the effect of two recent domestic airline alliances. We find that both alliances benefited consumers - average fares fell and total traffic increased after the creation of the alliances on those city pairs affected by the alliances. We also find that these effects are found both on city pairs where the alliance created one or two new online carriers, and on city pairs where the alliance increased the service offered by one or both alliance partners. Finally, we find that the size of the fare effect of the alliance depends on the pre-alliance level of competition on a city pair with the effect being larger on those city pairs where the level of competition was relatively low.

The Antitrust Division claimed that the schools conspired on financial aid policies in an effort to reduce aid and raise their revenues. The schools justified their cooperative behavior by explaining that it enabled them to concentrate aid on only those in need and thereby helped the schools to achieve their goals of need-blind admission coupled with financial aid to all needy admittees. This paper analyzes the empirical determinants of tuition and finds that the schools' agreement had no effect on average tuition paid. The paper also analyzes the appropriate application of the antitrust laws to not-for-prof...
