Endogenous network formation in local public goods: An experimental analysis
通过实验研究异质性个体如何内生形成网络以共享公共品产出，发现实际行为比理论预测更密集，有时降低效率，但随重复博弈趋近均衡。
We experimentally explore public good production levels and the endogenous formation of network structures to facilitate output sharing among agents with heterogeneous production costs and consumption valuations. Results corroborate the key theoretical insights of Kinateder and Merlino (2017) characterizing how agents form core-periphery networks. However, subjects often produce more and form denser networks than predicted, which sometimes reduces efficiency. There is some tendency for behaviour to converge towards the theoretical equilibrium over repeated play. Our results help us understand the emergence of the law of the few in real-world networks, and suggest it is driven by endogenous sorting of heterogeneous agents.
