ADDRESSING SOCIAL DILEMMAS WITH MASCOTS, INFORMATION, AND GRAPHICS
通过实验室实验，研究吉祥物、公共信息和数据可视化如何改善集体行为以应对非点源污染的社会困境，发现吉祥物表达负面情绪、提供水质公共信息和负面反馈能减少污染。
Reducing nonpoint source pollution is a complex social dilemma involving externalities, information asymmetries, and coordination problems. Using a laboratory experiment, this research investigates how mascots, public information, and data visualization can improve collective group behavior to address a social dilemma. Results show that groups reduce pollution in the experiment when a community mascot expresses negative emotions in response to poor water quality outcomes. Additionally, groups pollute less when they are provided public information about water quality, and abatement is greater when feedback is negatively framed. This study demonstrates how novel nonmonetary incentives can be used to achieve a collective environmental goal.
