Collaborative Research in Individual and Group Decisions in Voluntary Collective Decision Making

这一建议建立并扩展了与分享利益和分担提供公共安全或公园等共同利益的成本问题有关的先前理论和实验研究。一个相关的问题涉及个人在志愿时间或自愿向慈善机构捐款时的自愿集体行动。研究的理论基础是贝叶斯博弈均衡模型，在此基础上可以推导出对预期行为的预测。基本的实验方法包括在严格控制的实验室环境中使用人类受试者，其中包括受试者之间的不完全信息和交流。每个受试者被要求做出关于捐款的决定，并被告知实验者将根据他们的捐款决定和其他人的决定确切地支付他们多少钱。这些实验探索了在一系列条件下的个人自愿集体行为，并将对个人在这些实验中使用的不同类型的选择策略提供见解。

This proposal builds on and extends prior theory and experimental research related to the problem of sharing benefits and dividing the costs of providing a common good such as public safety or parks. A related question involves individual voluntary collective action when volunteering time or making voluntary contributions to charities. The theoretical foundation of the research rests on bayesian game theoretic equilibrium models on the basis of which predictions of the expected behaviors can be derived. The basic experimental methods involves using human subjects in carefully controlled laboratory situations involving incomplete information and communications between subjects. Individual subjects are asked to make decisions about contributing and are informed exactly how much they will be paid by the experimenter, depending upon their contribution decisions and the decisions of others. The experiments explore individual voluntary collective actions under a range of conditions and will provide insights as to the different types of choice strategies which individuals utilize in these experiments.
