Two are better than one. Individuals’ contribution to “unpacked” public goods. Economics Letters, vol. 104, pp. 31-33

 

Abstract:

We experimentally demonstrate how “unpacking” provides a possible approach for mitigating the dilemma of public goods provision through private contributions. Subjects’ total contributions increase when a single public good is split into two identical public goods.
