Do Women Supply More Public Goods Than Men? Preliminary Experimental Evidence from Matrilineal and Patriarchal Societies by Steffen Andersen, Erwin Bulte, Uri Gneezy and John A. List. Published in volume 98, issue 2, pages 376-81 of American Economic Review, May 2008

We implement a public goods game and a social intervention modeled after a public goods game in rural Sierra Leone near the Gola Forest Reserve. We also collect demographic, economic and forest conservation data on households in the area. We use this data to assess the mapping of social preferences from the artefactual field experiment (AFE) into real world behavior. We find evidence of heterogeneity in shifting factors between the AFE, the field experiment, and conservation outcomes. We also find evidence that social controls like war violence and witchcraft may explain some of this correlation.
