Carbon is forever: A climate change experiment on cooperation
通过实验室实验，研究了温室气体排放的持久性如何影响人们的合作减排行为，发现污染累积时合作先高后低。
Greenhouse gases generate impacts that can last longer than human civilization itself. Such persistence may affect the behavioral ability to cooperate. In a laboratory experiment, we study mitigation efforts with dynamic externalities in a framework that reflects key features of climate change. In treatments with persistence, pollution cumulates and generates damages over time, while in another treatment it has only immediate effects and then disappears. We show that with pollution persistence, cooperation is initially high but then systematically deteriorates with high stocks of pollution.
