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...

We simulate in a randomised lab experiment the effect of Cash Mobs on consumers' behaviour in an original variant of the multiplayer Prisoner's dilemma called Vote-with-the-wallet Game (VWG). The effect is modelled in a sequential game with/without an environmental frame in which a subset of...

We devise a ‘nudging' natural experiment to test the impact of a simple form of advertising on environmentally responsible products with/without the increase of the responsible product price. We find that the simple use of a small shelf-poster explaining the importance of buying a green...
