When this work was published most economic models routinely assumed that material self-interest is the sole motivation of all people engaging in economic activities. In such models fairness considerations or preferences for cooperation don’t play a role when researchers analyze the outcome of economic interactions. However, there is evidence suggesting that some people care about fairness or have a preference for cooperation.
The authors show in this widely renowned paper that the presence of such heterogeneous preferences has important implications on the outcome of economic interactions. Under certain conditions cooperative people can even force selfish people to act cooperatively. Behavioral economists have continued to research on this topic and gathered a variety of additional insights which today help us to fix such apparently difficult problems as changing corporate cultures for the good.
