Comprehensive Research for a competition of suppliers and an exclusive public goods provision mechanism

本研究以内生制度形成为视角，对公共物品提供中的自愿贡献进行实验研究。重点是探索进一步提高整体效率的替代制度形成机制。我们发现，机构的自愿参与和机构内部的多元投票规则在多个可用缴费水平之间进行决定会产生令人满意的结果。与其他机制相比，这一改进主要是由于最初没有加入该机构的玩家的贡献增加了。

This research treats an experimental study of voluntary contribution to public goods provision with endogenous institution formation. The main focus is on exploring alternative institution formation mechanism that further improves the overall efficiency. We found that the voluntary participation of institution and a plurality voting rule within the institution to decide among multiple available contribution levels generates a satisfying results. Comparing to other mechanisms, the improvement is mainly due to a increased contribution from players who do not join the institution in the first place.
