Difference between estimated reform-effect on the rich (a=6) and the poor (o=-4). The illustrative reform scenarios point to the heterogeneity of the effects of structural reforms on household incomes across the income distribution (Figure 21). The inequality implications from structural reforms depend on how inequality is measured, i.e. on the differential emphasis that different measures attribute to different portions of the income distribution. In turn, this choice partly reflects social preferences, that is, inequality aversion.
