Several days ago, during a phone call, I was asked to “hold” for a moment. 5 minutes passed. No one returned. I considered hanging up but thought, I’ve already waited 5 minutes. They will have been wasted if I leave. 10 minutes passed. Still no one.

The Jets are having the same experience with their quarterback. Paid $8.25 million next year whether he plays or not, Mark Sanchez has had 2 mediocre seasons. Just as I waited 5 minutes, and then 10 minutes, the Jets too feel they have an investment.

My 10 minutes and their $8.25 million are “sunk costs.” Whatever we paid is gone. Thinking rationally, we should look to what the future will cost us. More time waiting on the phone? More losing games?

According to one psychologist who has studied sunk costs, the bigger the past cost, the more unrealistic people are about its rosy future potential. Because they perceive waste and even harm to a reputation, people demonstrate “cognitive dissonance,” an unrealistic assessment of their future behavior. As a result, they continue the behavior rather than accepting a loss and moving on.

So, as Boeing ponders problems with its 787 Dreamliner and you decide whether to wait for the end of a boring video, your sunk cost should not affect your decision about continuing. Instead, compare future cost and benefit.

Sources and Resources: Thanks to James Surowieki for an excellent New Yorker column on sunk costs that took me to psychologist Hal Arkes’s study of sunk costs. More on athletes and sunk costs is here.

airlines industry...airplanes.16825_3.15a_000002547262XSmall

Spirit Airlines is doing everything it can to charge us less for a seat on one of its planes. One gentleman paid $77 for a round trip seat between Chicago and Fort Lauderdale.

Just the seat.

How much more could he have paid? You might want to try matching each of the following Spirit Airlines fees to one of the items listed below.

The fees:

  • 1. $100
  • 2. $4
  • 3. $28-$38
  • 4. $3
  • 5. $30-$45
  • 6. $5
  • 7. $75
  • 8. $6
  • 9. Free

 

The items:

  • a. check bicycle
  • b. buy water
  • c. first checked bag
  • d. get boarding pass a airport
  • e. transport dog
  • f. carry-on bag for overhead bin
  • g. buy bag of nuts
  • h. tuck items under the seat
  • i. buy a beer

(Answers at the bottom)

On the surface, it just looks like passengers pay a fee and the airline generates more revenue. But there is more. Because of the carry-on and checked luggage charges, passengers pack less. Less luggage means lighter planes. Lighter planes need less fuel–a huge cost saving for airlines.

Spirit also eliminated reclining seats on their Airbus 320s so that they could fit approximately 40 more fliers onto the plane. Think about it. Whether flights are full or empty, they still need the plane, the fuel, the pilot. And they charge for almost everything else.  An extra passenger costs them very little.

An economist would say that Spirit was really good at thinking at the margin. Defined as the “extras,” the margin is where Spirit adds to revenue and saves on costs.

Thinking at the margin, Spirit probably even made money on the gentleman who paid $77 for his Chicago/Ft. Lauderdale round trip.

While my Spirit facts and the matching idea came from a WSJ.com article, I especially recommend this very clever interactive graphic that displays the shifting position of the major airlines since deregulation in 1978.
