Titre: Feedback and cooperation: An Experiment on sorting behaviour (Noémi Berlin, Mamadou Gueye, Stéphanie Monjon)

Résumé: In this paper, we use a laboratory experiment to analyze the effect of information provision (feedback) on individual sorting behavior. To be effective, sorting must be a mixture of quantity and quality. However, increasing quantity may reduce quality due to the increasing risk of contamination. We consider a two-stage coordination game in which individuals first choose whether or not to participate in the sorting activity, and then complete a collective sorting task. The performance, a mixture of quantity and quality, of their sorting is measured. In this situation, information about the partner’s past performance and information about one’s own past performance are used as feedback treatments. Using a between-subjects experimental design, we find that providing feedback about own performance to an individual who decides to engage in a sorting activity is more efficient than not providing information and than providing information about the partner’s performance. Although the experiment is uncontextualised, the results have direct consequences on any situations implying an individual decisions in a collective task (e.g. waste sorting behavior).
