Abstract

Through a field experiment based on the prisoner's dilemma, we analyze the determinants of cooperative behavior in the horticultural sector, specifically on the effect of group membership. We focus on the Flowers for Bees Week initiative, a collective action in the supply chain (in particular producers and landscapers). We compare the behaviors of professionals in a repeated prisoner's dilemma game over 5 days, in two treatments: in-group (the players have the same role in the sector) and out-group (one player is a producer and the other a landscaper). The results are threefold. First, cooperation is higher in the in-group treatment compared to the out-group treatment. Second, when they cooperate, it is because they believe that the other will also cooperate. Lastly, the two sectors share the same views on collective actions and cooperation. We suggest levers to encourage collective actions in the sector.
