This paper is about the horizontal inequity of the Italian tax-benefit system and the joint impact of recent changes to the direct taxation system, family allowances and child benefits. The IT-EXEMPT static microsimulation model is employed to compare a scenario that replicates the tax-benefit system as of 2019 with a scenario that incorporates the changes to PIT and Bonus IRPEF in the period 2020-2022 and simulates the introduction of the Assegno unico e universale. The comparison focuses above all on the results of the cost-of-inequality decomposition approach put forward by Duclos et al. (2003). The classical horizontal inequity effect is broken down by population groups. The analysis shows a generalised reduction of horizontal inequity following the legislative changes. The categories that benefit most are high-income individuals, graduates, individuals whose household income is made up primarily of self-employment income or retirement income, individuals belonging to households without children, and those with four or more children among individuals with children.

Abstract
This paper is about the horizontal inequity of the Italian tax-benefit system and the joint impact of recent changes to the direct taxation system, family allowances and child benefits. The IT-EXEMPT static microsimulation model is employed to compare a scenario that replicates the tax-benefit system as of 2019 with a scenario that incorporates the changes to PIT and Bonus IRPEF in the period 2020-2022 and simulates the introduction of the Assegno unico e universale. The comparison focuses above all on the results of the cost-of-inequality decomposition approach put forward by Duclos et al. (2003). The classical horizontal inequity effect is broken down by population groups. The analysis shows a generalised reduction of horizontal inequity following the legislative changes. The categories that benefit most are high-income individuals, graduates, individuals whose household income is made up primarily of self-employment income or retirement income, individuals belonging to households without children, and those with four or more children among individuals with children.Pubblicazioni consigliate
