This paper inverts the usual logic of applied optimal income taxation. It starts from the observed distribution of income before and after redistribution and corresponding marginal tax rates. Under a set of simplifying assumptions, it is then possible to recover the social welfare function that...

Drawing from the formal setting of the optimal tax theory (Mirrlees 1971), the paper identifies the level of Rawlsianism of some European social planners starting from the observation of real data and redistribution systems and uses it to build a metric that allows measuring the degree of...

European countries have the world’s most redistributive tax and transfer systems. While they have been well equipped to deal with vertical inequality - that is, fostering redistribution from the rich to the poor - less is known about their performance in dealing with horizontal inequality,...

Existing tax schedules are often overly complex and characterized by discontinuities in the marginal tax burden. In this paper we propose a class of progressive smooth functions to replace personal income tax schedules. These functions depend only on three meaningful parameters, and avoid the...

Contrary to frequent recommendations of the public finance literature and international institutions, a persistently high tax wedge on labor is observed in Europe. Simultaneously, the scope for shifting taxes to more growth-friendly revenue sources appears underused. This motivates our...

Given the increased availability of survey income data, in this paper we analyse the pros and cons of alternative data sets for static tax-benefit microsimulation in Italy. We focus on all possible alternatives, namely using (a) SHIW or (b) IT-SILC data using a consistent net-to-gross...

Whether observed differences in redistributive policies across countries are the result of differences in social preferences or efficiency constraints is an important question that paves the debate about the optimality of welfare regimes. To shed new light on this question, we estimate labor...

This paper presents baseline results from the latest version of EUROMOD (version I3.0+), the tax-benefit microsimulation model for the EU. First, we briefly report the process of updating EUROMOD. We then present indicators for income inequality and risk of poverty using EUROMOD and discuss the...

Redistribution is usually understood in terms of income; as a way to rank individuals as well as to determine taxable capacity or benefit eligibility. Yet, it is increasingly argued that more prominence should be given to the joint distribution of income and wealth and interest into the taxation...
