Abstract

We use experimental data from the ‘vote with the wallet’ multiplayer prisoner’s dilemma to investigate with a finite mixture approach the effect of a responsible purchase on players’ satisfaction. We find clear-cut evidence of heterogeneity of preferences with two groups of players that differ significantly in terms of effects of the responsible choice on satisfaction
