''On the coexistence of reciprocity and materialism''
( 2007, Vol. 3 No.59 )
This paper studies the problem of the long-run preferences distribution in a large population using an evolutionary approach. Special attention is given to the investigation of the property of the mixed population equilibria, in which materialists and reciprocators coexist. Some of the players with reciprocal preference care about not only their own material payoffs but also about those of others, while the remaining ones are materialists who maximize their own material payoffs.
Keywords: Evolution
