ABSTRACT
Tables ll-13 have the same structure as before but focus on the impact of age. These tables suggest that between-group inequality, both short and long run, has increased dramatically over time. Seniority matters! Within group inequality is larger the older the group. This is also due to accumulation of returns to different investments, opportunities, and attainments. Short-run inequalities increase within groups, while long-run inequalities are stable with a moderate increase toward the end of this period. Maasoumi et al. (1996) find these trends have continued. Finally we note that these figures are based on per capita incomes. Since family size and composition changes over time these figures show greater volatility than the authors found with total family incomes unadjusted for family size (Maasoumi and Zandvakili 1989, Appendix).
