Indirect reciprocity can stabilize cooperation without the second-order free rider problem
Article Abstract:
The study considers a large population subdivided into randomly formed social groups of size 'n' in order to demonstrate that indirect reciprocity can stabilize collective action without the second-order free rider problem. It is also demonstrated that such a strategy couldn't invade a population, in which indirect reciprocity is not linked to collective action, thus leaving unexplained how collective action arises.
