Lifetime And Vertical Intertemporal Inequality, Income Smoothing, And Redistribution: A Social Welfare Approach


  • Rafael Salas
  • Isabel Rabadan


Between and within‐households intertemporal inequality indices are proposed to highlight the vertical and lifetime (i.e. cyclical) components of overall intertemporal inequality. Comparison with the classical static inequality indices is made. Income redistribution and smoothing (i.e. stabilization) are conveniently defined as the public policy impact on welfare, by means of the relative increase in intertemporal vertical and cyclical equity, respectively. The issue is important as many public policies are aimed at both (vertical and cyclical equity) objectives. Our approach provides a more appropriate evaluation of the desirability of public reforms aimed at achieving a greater vertical and cyclical equity, within a social welfare framework.
