Incentives in action: Airport tarmac delays

Filed under: econ — jlm @ 09:50

When the New York airports re-opened following the recent blizzard, there was a backlog of flights, and short-staffed airline terminal support personnel couldn’t process them as fast as they arrived. Which planes do you think got serviced, and which delayed on the tarmac for hour after hour?

It’s no surprise if you know that the rule put into effect after repeated and persistent multi-hour tarmac delays by the airlines applies only to domestic flights. Miraculously, just enough personnel were found to keep the domestic flights coming to the gates without hitting the delay lengths which would trigger fines — but not enough to service the international flights, for which there are no tarmac delay penalties.

And that’s why the flight from Vancouver, BC to Kennedy Airport sat on the tarmac for over 12 hours. Airlines had no incentive to service it, but did have an incentive to prioritize domestic flights over it. Corporations don’t feel shame or guilt for bad behavior, but they do feel the sting of fines and act to avoid them. We need to choose our incentives carefully.

Centuries ago, we lived in ignorance, our vision dim, not even knowing what we didn’t know. Now and then some people struck sparks as we stumbled in the darkness, and saw something others had missed.
But, on this day, a man was born who was to kindle a torch and connect heaven and earth.
Though his work and teachings, he changed our worldview forever. He revealed truths and laws that mankind had had no conception of before. He turned our old notions upside-down with a new understanding of the heavenly realm, and of the world on which we live. His teachings have stood the test of time, still being taught, analyzed, and widely used in practice to this very day. The great thinkers of later ages have taken what he revealed, and built magnificently upon it, each generation using the work of the previous to go further.

Happy birthday, Isaac Newton!
