In the course of researching my next novel, I happened upon this old paper by Robert H. Frank, Thomas Gilovich, and Dennis T. Regan, "Does Studying Economics Inhibit Cooperation?" Its conclusions: Economics grad students are more likely to free ride than the general public. Economists are less generous than other academics in charitable giving. Economics undergrads are more likely to defect in prisoner's dilemma problems. Students are less likely to return found money after studying economics but not after studying another subject like astronomy. No wonder they call it "the dismal science."
A study by Gerald Marwell and Ruth Ames found that students of economics are indeed much more likely to free-ride in experiments that called for private contributions to public goods. Their basic experiment involved a group of subjects who were given an initial endowment of money, which they were to allocate between two accounts, one “public,” the other “private.” Money deposited in a subject's private account was returned dollar for dollar to the subject at the end of the experiment. Money deposited in the public account was first pooled, then multiplied by some factor greater than one, and then distributed equally among all subjects.
Under these circumstances, the socially optimal behavior is for each subject to put her entire endowment in the public account. But the individually most advantageous strategy is to put all of it in the private account. The self-interest model predicts that all subjects will follow the latter strategy. Most don't. Across eleven replications of the experiment, the average contribution to the public account was approximately 49 percent.
It was only in a twelfth replication with first-year graduate students in economics as subjects that Marwell and Ames obtained results more nearly consistent with the self-interest model. These subjects contributed an average of only 20 percent of their initial endowments to the public account, a figure significantly less than the corresponding figure for noneconomists (p.05).
The EVATAR is a working model of a reproductive system made from a mouse ovary and bits of a human uterus, cervix, vagina, fallopian tubes, and liver. Developed by Northwestern University researcher Teresa Woodruff and her colleagues, the EVATAR is intended to help better test the effects of medicines and toxins on women. And now […]
Texas State University’s Body Farm (AKA Forensic Anthropology Center at Texas State University or FACTS) is a 45-year-old facility where the corpses of medical body donors are left to decompose so that researchers can observe the rate at which human remains are consumed by the elements, scavengers and microbes, allowing them to accurately date the […]
A better understanding how a sperm swims its way toward an egg could help inform new treatments for male infertility. Researchers from the University of York have now come up with a mathematical formula to model how large numbers of moving sperm interact with fluid they’re swimming through. From the University: By analysing the head […]
Maybe it’s entirely because of podcast ads, but drag-and-drop tools like Squarespace have gotten immensely popular in recent years. While it’s definitely a great tool for any non-coders who want to get a small website up and running quickly, managing content with a primarily visual interface can become a pain once you have more than […]
When you can’t wait for the world’s longest meeting to end, the mindless leg bouncing makes your boredom obvious and just annoys everybody else. Everyone knows the TPS reports need the damn cover sheet, but some sadistic colleague keeps forgetting, probably on purpose just to eat into your lunch hour. Enough is enough!While serving a […]
