Book Description
Previous research on airline demand has recognized the existence of at least two customer types, business passengers with high valuations of time and low price elasticity, and tourists having low valuations of time and high price elasticity. Attempts to differentiate between these two groups have generally been based on assumptions about the range of fares paid by each group or the classification of specific routes into "tourist" and "business". This research uses a differentiated products supply-and-demand model to disentangle the separate effects of hubs on costs and markups. On the demand side, it attempts to capture the fact that airline customers are heterogeneous by allowing customers' preferences over various product specifications to be drawn from a binary distribution. On the cost side, it estimates a very flexible spoke marginal cost function, so as to allow economies of density to vary across different ranges. Demand is estimated in a nested logit framework using unaggregated data from up to 200,000 products from as many as 18,000 markets per quarter. Markups, and thus marginal costs, are obtained on the basis of the assumption that firms price products to maximize profit in each market. Marginal cost is then estimated as a cubic function of leg distance and density. The model is first applied to data for a single quarter to gain an understanding the nature of the advantages enjoyed by carriers at their hub airports. It is then independently applied to data for the fourth quarters of nine consecutive years in order to elucidate the changes which may have occurred to costs and demands as firms reconfigured their fleets and learned the art of "yield management". Finally, adapted to the analysis of pooled time series data, the model is applied to the fourth quarters of the years 1989 through 1993 in order to determine the affect on demand and cost of the several bankruptcies which occurred during that period.

Book Description
The third manuscript studies the entry patterns of virtual code-sharing alliances. Specially, I examine the entry patterns of United-US Airways virtual code-sharing alliance. I use a probit model to estimate the reduced-form equation for the entry decisions of virtual code-sharing alliances. The empirical results suggest that Southwest Airlines is not the direct competitor to virtual code-sharing alliances.

Book Description
This dissertation studies the effects of firm's collaborative strategy on both demand and supply, and equilibrium to derive various welfare implications. I explain both horizontal mergers and vertical relationships, focusing on the U.S. airline industry. In the first study, I address significant limitations of traditional merger simulations which have focused solely on price changes while constraining the set of product characteristics to be identical pre- and post-merger. To overcome the limitations, I endogenize both prices and product characteristics by specifying a two-stage oligopoly game. After estimating demand and supply system, I simulate the effect of the Delta and Northwest Airlines merger on prices, product characteristics, and welfare. The simulation results show that the merged firm tends to increase product differentiation post-merger, the higher product differentiation reduces the firm's incentive to raise prices, and the changes in characteristics and prices increase not only the merged firm's profit but also consumer welfare. I also compare the predicted to actual post-merger outcome and find that endogenizing product characteristics is essential to better predict the actual outcome. The second study investigates the impact of contractual agreements regarding gates between airports and carriers on major carrier's market power. Competition Plans reported by thirty one hub airports provide information on a carrier's gate-occupancy, sublease agreement, and Majority-In-Interest clauses at an airport. I estimate the effects of these contractual practices on passengers' utility and carriers' marginal costs. The main results show that a carrier's gate dominance has a positive effect on the demand side through passengers' utility, and business travelers have a higher willingness to pay for gates than tourists. On the supply side, a carrier's gate dominance decreases its own marginal cost, especially when the airport is congested. Furthermore, the existence of sublease agreement at an airport is likely to increase non-signatory carriers' marginal costs, whereas the provision of Majority-In-Interest clauses increases signatory carriers' marginal costs. Based on the estimates, I execute a counterfactual analysis and find that regulatory limits on gate occupancy can reduce the differentials in costs and profits between signatory and non-signatory airlines.

Book Description
This book represents a milestone in the progression of Data Envelop ment Analysis (DEA). It is the first reference text which includes a comprehensive review and comparative discussion of the basic DEA models. The development is anchored in a unified mathematical and graphical treatment and includes the most important modeling ex tensions. In addition, this is the first book that addresses the actual process of conducting DEA analyses including combining DEA and 1 parametric techniques. The book has three other distinctive features. It traces the applications driven evolution and diffusion of DEA models and extensions across disciplinary boundaries. It includes a comprehensive bibliography to serve as a source of references as well as a platform for further develop ments. And, finally, the power of DEA analysis is demonstrated through fifteen novel applications which should serve as an inspiration for future applications and extensions of the methodology. The origin of this book was a Conference on New Uses of DEA in 2 Management and Public Policy which was held at the IC Institute of the University of Texas at Austin on September 27-29, 1989. The conference was made possible through NSF Grant #SES-8722504 (A. Charnes and 2 W. W. Cooper, co-PIs) and the support of the IC Institute.
