Confusion and learning in the voluntary contributions game
通过有限信息环境实验，检验困惑与学习对自愿贡献博弈中合作行为的影响，发现合作及其衰减并非单纯由困惑或学习造成。
Abstract We use a limited information environment to assess the role of confusion in the repeated voluntary contributions game. A comparison with play in a standard version of the game suggests, that the common claim that decision errors due to confused subjects biases estimates of cooperation upwards, is not necessarily correct. Furthermore, we find that simple learning cannot generate the kind of contribution dynamics commonly attributed to the existence of conditional cooperators. We conclude that cooperative behavior and its decay observed in public goods games is not a pure artefact of confusion and learning.
