The Role of Altruism in Economic Interaction

John C. Haltiwanger and Michael Waldman , Journal of Economic Behavior and Organization 21(1) , 1-15 , May 1993.
Abstract:

This paper considers environments in which the population consists of a mix of altruists and egoists, and asks under what situations do altruists have a disproportionately large effect on equilibrium, and under what situations is it the egoists. We begin by presenting a general framework for answering this question. We then apply the framework to the analysis of three economic environments: (1) the classic problem referred to as the Prisoner's Dilemma; (2) a world where agents decide whether or not to pollute the environment; and (3) a world where agents decide whether or not to donate blood.
