The research strategy employed by Carter and Irons was to compare the performance of economics majors and other students and see which group came closer to the predictions of the self-interest model. In a sample of 43 economics majors, the average minimum amount acceptable by the receiver was $1.70, as compared with an average of $2.44 for a sample of 49 noneconomics majors (p&lt;.05). As receivers then, economics majors came significantly closer than nonmajors to the behavior predicted by the self-interest model.
