This paper examines the relationship between variations in group size and "free-riding" behavior in the voluntary provision of public goods. We examine experimentally two pertinent concepts: the marginal return to an individual from contributions to the public good, and the actual number of members in the group. Our results strongly support a hypothesis that increasing group size leads to a reduction in allocative efficiency when accompanied by a decrease in marginal return from the public good… 
A Rationale for Non-Monotonic Group-Size Effect in Repeated Provision of Public Goods
This paper analyzes the impact of a group-size change on contributing incentives in repeated provision of pure public goods. We develop a model in which the group members interact repeatedly and
Discrimination via Exclusion: An Experiment on Group Identity and Club Goods
We study using laboratory experiments the impact on cooperation of allowing individuals to invest in group-specific, excludable public goods. We find that allowing different social groups to
Voluntary Association in Public Goods Experiments: Reciprocity, Mimicry and Efficiency
We find that a process of voluntary association where individuals express a preference about whom they want to be associated with can create strong incentives to increase efficiency and contributions
Free-rider effects in rent-seeking groups competing for public goods
This paper studies individual behavior within a group when there is rent-seeking and groups compete in the selection of a public good — a variant of the traditional public goods problem. The
Does Heterogeneity Help in Overcoming the Public Goods Dilemma in a Sequential Contribution Environment?
This paper compares behavior of heterogeneous groups with homogeneous groups in public goods production. In heterogeneous groups members differ in their opportunity costs of contribution, while in

Group Size and Incentives to Contribute: A Natural Experiment at Chinese Wikipedia
The literature of private provision of public goods suggests that incentive to contribute is inversely related to group size. This paper empirically tests this relationship using field data from
