Experimental Details

Interventions

Intervention(s)
The intervention, part of an experiment designed to measure social capital, evaluates individual decisions through three economic games conducted in pairs (Dictator Game, Trust Game, Prisoner's dilemma).
Each participant interacts with five different people from a particular group. In the PD game, there is a random assignment into one of three tratments: recommendation (the participant can suggest a decision to the other player), leader (the participant is chosen to be a "leader"), recommendation+leader (the participant is chosen to be a "leader" and can suggest a decision to the other player).
