Abstract

This paper analyzes the impact of inequality in the distribution of endowments on contributions. We conduct a lab experiment using the well-known Public Good Game to test the relation between inequality and contribution to a public fund. We introduce the possibility to choose among three different redistribution rules: equidistribution, proportional to contribution and progressive to endowment. This novelty, combined with a payoff function that depends also on previous period behavior, allows us to verify the hypothesis that players show inequity averse preferences. Results show that inequality has a negative impact on individual contribution. Since inequality is decreasing during repetitions, we deduce that players show inequity averse preferences.
