Figure 1: Game structure.

(a) The sequential game. Player A can make any offer to Player B. Here we illustrate all the options that Player B has to reapportion the money after being offered a split of $9/$1. On each round, however, Player B is presented with a forced choice between two options (for example, compensate versus equity, compensate versus accept, compensate versus punish, and so on) for a total of 10 pairwise comparisons. Options were randomly paired and presented across the experiment. We focused our analysis on unfair offers, splits of $6/$4 through $9/$1. (b) An example of a round where Player A offers Player B $1. In this case Player B is then presented with the option to either increase their own payout without decreasing Player A’s payout (compensate), or reverse the payouts such that Player A receives $1 and Player B receives $9 (reverse).
