  abstract  = {We suggest a differential version of monotonicity for redistribution rules: whenever the differential of two persons' income weakly increases, then the differential of their postredistribution rewards also weakly increases. Together with efficiency and non-negativity, differential monotonicity characterizes redistribution via taxation at a fixed rate and equal distribution of the total tax revenue.},
