Le Séminaire d’Économie des Transports regroupe tous les mois des chercheurs autour de la présentation des travaux d’un chercheur invité. L’objectif de ce séminaire est de renforcer l’émulation scientifique au sein du laboratoire et de créer ou renforcer les collaborations avec les chercheurs invités et leurs laboratoires respectifs.

Buffer choices among US carriers: a Southwest effect?
Avec Miguel Urdanoz
Résumé : Airlines add extra time to their schedules to control excessive delays. This extra time, known as buffer, is strategic as it leads to opposite effects: increase (decrease) in on-time performance and increase (decrease) in operating costs in case of higher (lower) buffer. Buffer has largely increased over the last two decades. However, our study shows a very different behavior across US carriers. Studying all flights operated between 2007 and 2017 in the US domestic market we observe that Southwest Airlines presents a very different behavior from all the other carriers. Moreover, our preliminary results show that the presence (entry/exit) of Southwest on a market affects the buffer choices by the other carriers present on the market. If these results are confirmed, our study shows that the presence of Southwest Airlines creates incentives to increase buffer and therefore to improve on-time performance.
