Perhaps it has something to do with their field of choice, economics AKA the dismal science, but many of the world's most famous economists share one extraordinary trait: they're cheapskates!
Some economists may be cheap, at least by the standards of other people, because of their training or a fascination with money and choices that drives them to the field.
In recent research, University of Washington economists Yoram Bauman and Elaina Rose found that economics majors were less likely to donate money to charity than students who majored in other fields. After majors in other fields took an introductory economics course, their propensity to give also fell.
"The economics students seem to be born guilty, and the other students seem to lose their innocence when they take an economics class," says Mr. Bauman, who has a stand-up comedy act he'll be doing at the economists' Atlanta conference Sunday night. Among his one-liners: "You might be an economist if you refuse to sell your children because they might be worth more later."
Economists long have studied "free riders," the sort of people who take more than their fair share of something when circumstances permit. Think of the person who orders the most expensive entr[eacute]e at a restaurant, knowing that the check will be shared equally among companions.
University of Wisconsin sociologists Gerald Marwell and Ruth Ames, in a 1981 paper, found that in experiments, economics students showed a much higher propensity to free ride than other students. In questioning after the experiment, the sociologists found that for many of the economics students, the concept of investing fairly "was somewhat alien."
