During his 2012 Princeton Baccalaureate Address, financial writer Michael Lewis describes a college psychology experiment in which students were divided into teams, each composed of 3 people with a randomly assigned a leader. Given a social problem like drinking or cheating, the teams were asked to brainstorm a solution. Then, 30 minutes after beginning, 4 cookies were brought to each group.

3 people, 4 cookies.

Who got the extra cookie?

Lewis tells us that in every group, the leader, the person who was arbitrarily selected, “grabbed” the cookie and ate it with gusto.

As Lewis continues:

“This leader had performed no special task. He had no special virtue. He’d been chosen at random, 30 minutes earlier. His status was nothing but luck. But it still left him with the sense of entitlement that the cookie should be his.”

Connecting his life, his books, CEO pay and Wall Street excess to his cookie story, Lewis focuses on how luck relates more closely to success than people admit. As he points out, for Princeton grads, their parents, their affluent country and their prestigious university all reflected some luck in their lives that then increased, “their chances of becoming even luckier.”

So, he asked, when life presents you with that “fourth cookie,” will you grab it?

Here is the 14 minute video of his excellent address and here is the transcript.

Also, you might find economic Nobel laureate Daniel Kahneman’s favorite equations interesting:

  • success = talent + luck
  • great success = a little more talent + a lot of luck

 

In Thinking Fast and Slow, Dr. Kahneman then uses some surprising golfing statistics, pp. 177-179, to illustrate his point and his discussion of our regression to the mean.

A wonderful baseball movie, Moneyball is also about economics.

The story focuses on the Oakland Athletics, a second-tier baseball team with a small budget. A speedy runner? A homerun hitter? The stars cost many millions that Oakland just did not have.

Faced with a futile future, the Athletics general manager, Billy Beane, realized a good team need not be about star players. Instead of individuals, it was actually about the whole team’s ability to win. And that meant looking more closely at why teams win. Beane concluded that it meant getting on base. And that meant walking was as valuable as hitting. It meant recognizing the small stuff that most people ignored.  It required processing countless stats and avoiding the human response on which baseball scouts depended. And it worked.

Listening to the “bean counters,” Beane put together a team of unknowns that together almost produced a championship.

In this fascinating NPR Fresh Air podcast, Michael Lewis talks about his book Moneyball.

The Economic Lesson

In the stock market, when buying a house, or when putting together a baseball team, price matters. People who identify a resource that is undervalued have the best chance of achieving success. For securities and home buyers, success means prices rise after you buy your asset. For Billy Beane, it was acquiring valuable players for a price he could afford.

This returns us to the role of prices. Prices convey information. Sometmes, though, goods and services are mispriced. Then, very wise people can benefit before the market realizes its mistake.

Billy Beane soon faced the problem that his undervalued players would gain value. And then, again, he could not afford them.

An Economic Question: In addition to undervaluing an asset, sports economists have said that Moneyball is about Joseph Schumpeter’s creative destruction. Do you agree? Explain.
