Extending previous research on the role of fairness in social dilemmas, two experiments investigated allocation preferences in public good dilemmas. In Experiment 1, fairness conceptions were a significant predictor of how participants allocated the public good to their group. Experiment 2 aimed at studying the impact of distributive goals on allocation preferences. Participants were assigned to one of three conditions in which the different goals were induced. As hypothesized, the different goals affected which allocation principle the groups used to allocate the resource. These findings suggest that people in a public good dilemma apply the allocation principle that serves a particular group goal, even though this may interfere with their perceptions of fair allocations
