Modern resource allocation theory is used to consider certain issues raised by the concept of altruism. Both state action and individual altruism may compensate for deficiencies in resource allocations. Both the state and individuals incur information costs, and these costs determine whether individual altruism or state action is used. Justice in the public realm makes altruism in the private realm unnecessary. I also show how what appears to be altruistic behavior may be an intertemporal resource allocation mechanism.
