We study the effect of consolidation on airline network connectivity using three measures of centrality from graph theory: Degree, Closeness, and Betweenness. Changes in these measures from 1990 to 2015 imply: i) the average airport services a greater proportion of possible routes, ii) the...

We develop a model of inter-temporal and intra-temporal price discrimination by airlines to study the ability of different discriminatory mechanisms to remove sources of inefficiency and the associated distributional implications. To estimate the model's multi-dimensional distribution of...

We provide empirical evidence that multimarket contact facilitates tacit collusion among airlines using a flexible model of oligopolistic behavior, where conduct parameters are modeled as functions of multimarket contact. We find i) carriers with little multimarket contact do not cooperate in...

We investigate whether stock price movements can inform operations managers as to where they should focus improvement efforts.We examine how unexpected performance along several dimensions of service quality - on-time performance, long delays and cancellations, lost bags and denied boardings -...

We formulate two empirical tests for collusive behavior based on the theoretical insights of Werden and Froeb [1994] and Athey, Bagwell, and Sanchirico [2004]. The first predicts that colluding firms will reduce pair-wise differences in prices within a market if demand satisfies certain...
