Schematics for the three different economic games with examples of monetary exchanges for each step. In the 2PP, participants received offers from the dictator (e.g., 10 MUs) and then, in the second step of the game, had the option to pay to punish the dictator (e.g., paying 5 to deduct 15 MUs). In both the 3PP and the 3PR, participants witnessed the dictator send an offer to the 2nd player and could again pay to punish the dictator. In the 3PR, participants had the additional option of paying to recompense the 2nd player (e.g., paying 6 to recompense 18 MUs).
