Conditional Rewarding Behaviour: An Experiment

Both peer-to-peer punishments and rewards can be effective in increasing cooperation in dilemma situations. We follow Kamei’s experimental design [2014, Economics Letters 124, pp.199-202], except we use a reward option instead of a punishment one. Consistent with Kamei (2014), decisions to reward are on average positively proportional to the others’ reward to the same recipient. We classify the rewarding types in a similar fashion and find fewer anti-social types.
