"Si él lo necesita": gypsy fairness in Vallecas

Abstract

“Si él lo necesita” (if he really needs it) was the most common argument given by the subjects who accepted the zero offer in the ultimatum game during experiments were conducted among illiterate (adult) gypsies in Vallecas, Madrid. Interestingly the acceptance of the zero offer was not a rare case but, in contrast, it was the modal value. This is even more remarkable if we consider that the 97% of the subjects proposed the equal split.
