We experimentally compare the consequences for group cooperation of two decision mechanisms involving the extension of …

We report on an experiment designed to explore whether a written expression of disapproval affects future levels of … cooperation. In between two identical public goods games, participants play a mini dictator game that, depending on the treatment …

In less cooperative social environments, where … antisocial punishment has been detected, punishment was detrimental to cooperation. The success of punishment in enhancing … cooperation was explained as deterrence of free riders by cooperative strong reciprocators, who were willing to pay the cost of …

This paper provides a new way to identify conditional cooperation in a real-time version of the standard voluntary … further contribution, and use a permutation test on contribution cycles to assign a measure of conditional cooperation to each … group play. The validity of the measures is tested in an experiment. We find that roughly 20% of the plays exhibit dynamics …

We investigate experimentally whether the extent of conditional cooperation in public good games depends on the … conditional cooperation. We also find no evidence that the type of game makes a difference to unconditional contributions. The …
