Are economists more selfish than other 'social' scientists?

There is considerable professional disagreement among economists about whet her economists are less cooperative than non-economists. It has been argued that once an individual has been schooled in the self-interest model of in dividual human behavior (s)he exhibits more selfish behavior than other, os tensibly similar individuals who have not been taught to fully appreciate H omo economicus. Heretofore, the empirical debate has centered around classr oom experiments designed to compare the "honesty'' of undergraduate economi cs majors versus non economics majors. However, methodological problems hav e plagued these studies, leaving both sides at an impasse. We offer unique and compelling real-world evidence that suggests economists are no less coo perative than non-economists. Indeed, after comparing the incidence of "che ating'' on their Association dues, we find that professional economists are significantly more honest/cooperative than professional political scientis ts, and especially, professional sociologists.
