(When) Do Hub Airlines Internalize Their Self-Imposed Congestion Delays?

by

Katherine Thomas Harback

We develop theoretical models of airport congestion with non-atomistic traffic and implement them empirically using data from twenty-seven major US airports to determine whether dominant airlines internalize or ignore self-imposed congestion.  Estimates of minute-by-minute delay patterns at each airport calibrate structural models of landing and takeoff queues as dynamic functions of traffic rates and airport capacities. These functions determine the internal and external congestion that aircraft impose on one another. Specification tests largely reject the internalization model. Optimal pricing values all time using non-dominant aircraft cost coefficients and treats all delays as external—i.e., fees equal opportunity costs of allocating peak capacity to dominant airlines.

The Lerner College is home to a state-of-the-art financial trading facility, the $1.4 million student-led Blue Hen Investment Fund, a student-managed restaurant and hotel, a high-technology development center of a global bank and a start-up experience for students with new business ideas.

Lerner College faculty - like Anu Sivaraman, who is among Social Media Marketing Magazine’s “Top 100 Marketing Professors on Twitter” and MBAprograms.org’s “Top 50 Marketing Professors on Twitter” - are thought leaders who command attention from influential business audiences, economists and policy makers.

All Lerner College departments offer experience-driven learning and emphasize evidence-based analytics methods to enrich the student experience. Here, finance students visit New York City’s financial districts for a first-hand look at markets trading and to meet with UD alumni.
