Freakonomics: Incentives in a Real World

Freakonomics: Incentives in a Real World


I exchange books with some folks in the Prague Engineering Center from time to time and I've got an interesting one from Martin Grebac lately: Freakonomics written by Steven Levitt and Stephen J. Dubner.

QUESTIONS, QUESTIONS, QUESTIONS

  • What do schoolteachers and sumo wrestlers have in common?
  • Why do drug dealers still live with their moms?
  • Would you rather send your kids to play with friends, whose parents have a gun or to a family house with swimming pool?
  • How did the legalization of abortion affect the rate of violent crime?

If you like provocative questions, Freakonomics is a book that you must read, although, you might come with different answers then the author[s].

What do schoolteachers and sumo wrestlers have in common?

This chapter is all about cheating. Or rather Incentives that drive specific behavior. Steven Levitt came with an idea that incentives, in addition to general economical meaning as financial incentives can also materialize in social or moral sphere. What motivates [some] people to clean up after their dogs in public areas?  Definitely no financial pressure. Why people give blood for free? Can it be boosted by offering them quite nice sum of money?
Or, speaking about bad behavior, why some teachers in US schools cheat? It's all about incentives.
BTW the author came up with a data mining idea for detecting the cheaters. Compare the statistical data from previous years, the same teacher, same class and look for patterns and deviations, that's the basics of his recipe.

WYMIWYG: What you measure is what you get

The chapter about incentives reminds me another slogan: WYMIWYG: What you measure is what you get. It's true in a positive as well as negative form. Imagine a company (can be of any kind of support, doesn't really matter), where people are measured by the 'Time to response'. Their motivation is to finish the call and close the case as soon as possible, which doesn't always mean that they helped a customer. Or not as much as the customer expects. Beside the example with real estate agents, that's nicely mentioned there, you might come up with other ones. Travel agent, that's motivated to sell you the ticket that's on the table, rather than spending a couple more minutes looking for the best price, is another example that come to my mind.

I'll write a couple more comments about the book next time, but I wonder what your experience is with metrics-oriented organizations. Any thoughts?

Hi, Pavel.

I enjoyed this book too. I loaned it to a friend and his 16 year old son snatched it and read it first. His opinion of the book: "It's too short." :)

I respectfully disagree, however, that WGMIWGD. Not always, anyway. As both you and the authors have illustrated, a measure can drive undesired behavior, whether it is a good measure or not.

I have at least one success in challenging a bad measure, and winning. I believe in measures when they are understandable and meaningful and encourage attaining the desired results.

Hi Carolyn,
we're on the same boat and I completely agree with your comment. What I really dislike is the measuring just for the sake of measuring or measuring XYZ, just because it's easy to measure that.
Keeping the goal, what you want to achieve in the first place is quite important.
