“The Effect of Income Heterogeneity in An Experiment with Global and Local Public Goods.” (PDF)
Abstract: Public goods such as climate change mitigation affect people in multiple locations. We report on a public goods experiment, where subjects can contribute not only to a local but also to a global public good. We study the effects of endowment heterogeneity by comparing a setting where two localities have the same income (homogeneous treatment) with a setting where the localities differ in income (heterogeneous treatment). We find that: 1) social efficiency is lower in the heterogeneous treatment; 2) the efficiency difference comes from two aspects: a shift from global to local public good contribution and a lower total public goods provision; and 3) inequality aversion and reciprocity both play a role in contribution behavior; however the former does not fully counter efficiency reduction, and the latter manifests an undesirable side effect: people reduce global public goods contributions to reciprocate on local public good contributions. Our findings suggest that policy interventions may be necessary to increase social efficiency with heterogeneous wealth and multiple public goods.
