Detecting motives for cooperation in public goods experiments
通过实验设计分离了公共品实验中合作行为的三种动机来源：困惑、一次性动机（如利他、不平等厌恶）和多轮动机（如策略动机、互惠），发现多轮动机是驱动合作的主要因素。
Abstract This study clarifies the types of motives that are important as a source of cooperation in a linear public goods experiment. Our experimental design separates contributions into those due to confusion, one-shot motives (which includes altruism, warm-glow, inequality aversion, and conditional cooperation), and multi-round motives (which includes a strategic motive under incomplete information, a failure of backward induction, and reciprocity). The experiment reveals that multi-round motives plays an important role in driving cooperative behavior. Confusion and one-shot motives play a minor role.
