We examine the effects of endogenizing contribution productivity in a repeated public good game. In our experimental treatment, subjects collectively decide (by voting) how much to invest in augmenting the technology for producing the public good, and subsequently make individual voluntary contributions to provision. In the control, contribution productivity is exogenous. Contributions in the two treatments are similar.
