Group-based crowdsourcing allows crowd workers to solve problems that they could not handle alone, but financial incentives for this type of work are not well understood. While cooperative game theory provides normative models for describing fair and stable reward divisions for groups, there has been limited empirical studies comparing these normative models with what people may prefer.
In this talk, I will discuss a study where we investigated how humans divide group-rewards when acting as impartial decision-makers in cooperative games, and show that people consistently violate several of the axioms that characterize theoretically fair reward divisions. Based on our results, we propose and evaluate descriptive models for human decision making with respect to group reward division, and discuss some of the impact these results have on group-based crowdwork.
