This paper aims to test the effect of fairness considerations on the decision to follow the law using experimental economics methodology. In a repeated public good game, we implement an incentivized obligation (i.e., minimum contribution level) that is enforced probabilistically. We implement the asymmetry of the enforcement by assigning heterogeneous monitoring probabilities to otherwise identical subjects in a public goods game. To understand how unfair implementation of the law affects individuals’ behavior, we compare average contributions in treatments with low, high, and asymmetric enforcement. Initial analysis of the results indicate no significant difference under symmetric or asymmetric enforcement of the law. The subjects reacted only to their own obligations and how those obligations were enforced upon others had no effect on their behavior.
