Airline Mitigation of Propagated Delays : Theory and Empirics on the Choice of Schedule Buffers

Brueckner, Jan K. - 2019

This paper presents an extensive theoretical and empirical analysis of the choice of schedule buffers by airlines. With airline delays a continuing problem around the world, such an under-taking is valuable, and its lessons extend to other passenger transportation sectors. One useful lesson from...

Airline Schedule Buffers and Flight Delays : A Discrete Model

Czerny, Achim Ingo - 2020

This paper revisits the airline schedule-buffer choice problem analyzed by Brueckner, Czerny and Gaggero (2020) using a simpler model where the random shocks influencing flight times are discrete rather than continuous. The analysis yields closed-form solutions for the flight and ground buffers...

Dynamic Ic and Dynamic Programming

Kwon, Suehyun - 2019

This paper develops a dynamic programming method when the one-stage deviation principle in the sense of mechanism design literature doesn’t hold. The commonly used dynamic programming method is valid only if the one-stage deviation principle in the sense of mechanism design literature is...

Optimal Epidemic Suppression Under an ICU Constraint

Miclo, Laurent - 2020

How much and when should we limit economic and social activity to ensure that the health-care system is not overwhelmed during an epidemic? We study a setting where ICU resources are constrained while suppression is costly (e.g., limiting economic interaction). Providing a fully analytical...

Supplier Encroachment with Mutual Outsourcing

Milliou, Chrysovalantou; Serfes, Konstantinos - 2023

We examine the incentives and implications of supplier encroachment, when final good produc-tion requires the use of multiple complementary inputs and the entry of a supplier into the final good market gives rise to mutual outsourcing of inputs between the encroaching supplier and the incumbent....

Is There News in Inventories?

Görtz, Christoph - 2020

We identify total factor productivity (TFP) news shocks using standard VAR methodology and document a new stylized fact: in response to news about future increases in TFP, inventories rise and comove positively with other major macroeconomic aggregates. We show that the standard theoretical...
