Operationalizing selfishness and inequality.
Selfishness (blue line) is defined as the percentage of the endowment the allocator took/kept for themselves ranging from 0 (when the allocator is most generous, allocating nothing to themselves) to 100 (when the allocator is most selfish, allocating all to themselves). Inequality (orange line) is defined as the absolute difference between the percentages of the endowment each person is left with post allocation ranging from 0 (when the split was 50/50) to 100 (when one person receives all and the other none).
