Stoff, Christian (2006). Establishing Cooperation between Groups: Ingroup versus Outgroup Punishment. Working paper series / Socioeconomic Institute No. 416, University of Zurich.
We analyse interethnic cooperation in an infinitely repeated prisoner’s dilemma when members of one group are unable to target punishment towards individual defectors from the other group. We first show that indiscriminate punishment may sustain cooperation in this setting. Our main result, however, is that the introduction of ingroup punishment in addition to outgroup punishment represents a better sanctioning institution in the sense that cooperative outcomes may persist in situations where outgroup punishment alone fails to induce cooperation. Our findings are consistent with historical evidence on the dynamics of interethnic conflicts.
