Research on ultimatum and dictator games has found that because of ''f
airness'' first movers in such games offer more than noncooperative ga
me theory predicts. We find that if the right to be the first mover is
''earned'' by scoring high on a general knowledge quiz, then first mo
vers behave in a more self-regarding manner. We also conducted dictato
r double blind experiments, in which the experimenter could not identi
fy the decision maker. The results yielded by far our largest observed
incidence of self-regarding offers, suggesting that offers are due to
strategic and expectation considerations. Journal of Economic Literat
