Abstract

This study measures spending power inequality within age cohorts and estimates fiscal progressivity via lifetime net tax rates. We find, first, that inequality in income and especially wealth dramatically overstates inequality in spending power. Second, inequality in current spending power differs from that in lifetime spending power because of credit constraints, in-kind government benefits, and other factors. Third, the US fiscal system is highly progressive once cohorts are old enough to have highly dispersed human wealth. Fourth, households’ rankings based on current income can differ substantially from their rankings based on lifetime resources. Fifth, current-year net tax rates substantially understate fiscal progressivity.
