内容提要:

Sustaining cooperation in social dilemmas is a fundamental objective in the social and biological sciences. While providing a punishment option to community members in the public-goods game (PGG) has been shown to effectively promote cooperation, this has some serious disadvantages; these include destruction of a society’s physical resources as well as its overall social capital. A more efficient approach may be to instead employ a reward mechanism. 

We propose an endogenous reward mechanism that taxes (at the rate of 20%) the gross income of each round’s PGG play and assigns the amount to a fund; each player then decides on how to distribute his or her share of the fund as rewards to other members of the community.  Our anonymous mechanism successfully achieves a high level of contribution (about 70%) with budget-balanced (1:1) rewards that require no external funding, an important condition for realistic implementation. Our results are consistent with the higher contribution levels under endogenous rewards being driven by two key components: First, a strategic response to reward formation can help avoid the no-contribution outcome. Second, conditional cooperation plays a crucial role in maintaining high levels of public-goods contributions.
