Distributional Consequences and Intentions in a Model of Reciprocity

Two types of theoretic approaches have been developed to model fair behavior. According to the "equity approach" fairness is solely driven by distributional concerns. Opposed to this consequentialistic perspective, the "reciprocity approach" stresses the importance of intentions. We discuss experimental evidence that demonstrates that in fact both intentions and distributional consequences matter. In this paper, we present a formal model of reciprocity that captures both, outcomes and intentions.
