Abstract

This research estimates a multi-product flexible cost function of airport variable costs. Data for the analysis are a panel of 50 airports from 1996 to 2008. Output includes domestic and international departures, non-aeronautical operating revenues, and the number of transport workload units, where a workload unit is a passenger or the equivalent of a 220 pound packet of cargo. The quasi-fixed factor is the equivalent number of 10,000′ × 150′ runways at an airport. After correcting for first-order serial correlation, the analysis finds that airports operate under constant returns to runway utilization and multi-product decreasing returns to scale, production technology is consistent with product specific returns to capacity utilization and anti-complementarity across outputs, and general airport operations have input substitution possibilities with personnel and contractual repair/maintenance inputs. The study also finds 1.05% technology progress over the sample period, due to strong growth prior to 2001, with similar productivity growth rates for large and medium hubs.
