Public Goods: A Survey of Experimental Research John O. Ledyard This paper surveys experimental research on public goods. It discusses the design and results of experiments that examine how individuals contribute to public goods, and what factors influence cooperation. The paper also discusses the challenges of conducting experiments on public goods, and the importance of controlling for variables that may affect outcomes. The paper begins with an introduction to public goods experiments, describing a simple experiment in which individuals are asked to contribute to a group project. The paper then discusses the theories that predict individual behavior in such experiments, and the results that have been observed. It also discusses the factors that influence cooperation, such as experience, repetition, and communication. The paper then discusses the challenges of conducting experiments on public goods, and the importance of controlling for variables that may affect outcomes. It also discusses the importance of understanding the behavior of individuals in public goods environments, and how this can inform the design of institutions that promote cooperation. The paper concludes with a discussion of the future of public goods research, and the potential for further experiments to improve our understanding of behavior in public goods environments.Public Goods: A Survey of Experimental Research John O.
