  Using data from 35 Participatory Budgeting instances in Amsterdam, we
empirically compare two different Participatory Budgeting rules: the greedy
cost welfare rule and the Method of Equal Shares. We quantify how proportional,
equal and fair the rules are and conclude that, for a small price in total
voter satisfaction, the Method of Equal Shares performs better on all notions
of fairness studied. We further provide a popular and a visual explanation of
the Method of Equal Shares.
