Free Riding and Collective Action: An Experiment in Public Microeconomics
通过实验检验搭便车假说，发现参与者行为符合假说但搭便车程度较低，说明该假说揭示标准公共微观经济学的不完备性，而非真实世界的描述。
The well-known free-rider hypothesis is examined experimentally to see (i) whether individuals behave systematically as free riders when systematic incentives to do so are created, and (ii) the extent to which free riding actually occurs. Though the experiment's participants behaved in accordance with the hypothesis, the quantitative extent to which such behavior occurred was rather modest. From this it may be concluded that the free-rider hypothesis as presently stated indicates an incompleteness in standard public microeconomics rather than providing a description of the real world
