Viviana Zelizer has a new book coming out in a week: Economic Lives: How Culture Shapes the Economy (or what’s left of the economy). I got an e-mail about it from Amazon. They’ve got me pegged.
Will I spend $23.62 for the book? If I thought rationally about money, I would consider what else that $23.62 could buy. But nobody thinks about money with perfect rationality. Dollars are fungible, but not completely so. They have a different value in different sectors of life and do not always flow easily from one sector to another. Exchange rates between sectors are idiosyncratic and rarely specified.
I was reminded of this yet again by Jacob Avery’s recent paper on poker players. Is it rational to bet an amount greater than your weekly paycheck on the turn of a card or the outcome of a baseball game? It’s irrational only if money is perfectly fungible from the world of gambling to the world of everyday living. But it isn’t.
The gamblers I knew would frequently say that “gambling money” was “sacred.” In other words, there was such a thing as gambling money, and it was different from other moneys. It fell under a different set of rules and valuations.
Here’s a slightly different example though also from the world gambling. It’s from a “This American Life” show originally broadcast in November, 2003.* The reporter is Mary Beth Kirchner.
This 2:20 excerpt is from a story about a limo driver in Las Vegas. He is a good blackjack player. Yet he will leave the table, where he’s making a bundle, so as not to miss the peak hours for catching fares, even though these will net him less money than blackjack:
Here’s a transcript from the last part of the clip:
JOE: I was playing about like $2000 a hand. And I told the doorman, “If you get a good ride, like to the golf course, come and get me,” y’know, like $75. Anyway, he came up to the table and told me, “Hey, I got a ride” Seventy-five dollars. The people in the pit, they all think I’m nuts, y’know. I just stopped.. I left, I took my money, and I ran down to take the guy for $75, and there I am playing two grand a hand.Nobody understands it? Viviana Zelizer does. So do most people, at some level. They know that their treatment of dollars is not universalistic They just don’t write books about it.
I try to separate the two. One has nothing to do with the other.
MARY BETH: I don’t understand that.
JOE: I know. Nobody does.
MAURY BETH: Do you understand it?
JOE: I don’t. I just. . . .Gambling to me is gambling, work is work.
*This is my first try at embedding an audio clip. If it doesn’t work, you can go to the full This American Life podcast (here): The story begins at about the 23 minute mark. The part I excerpted here begins at about 33:20.
