Applied welfare analyses of redistributive systems nowadays benefit from powerful tax benefit microsimulation programs combined with administrative data. Arguably, most of the distributional studies of that kind focus on social welfare defined as a function - typically inequality or poverty...

In this paper we want to provide an utopian attempt to tackle inequality and to tackle, most specifically, what we consider the cultural and ethical origin of inequality: paid work. We believe that a globalised world, structured around the asymmetry between an increasingly small number of...

Belgium has seen major changes in its tax-benefit system over the past twenty years. These changes have, to a large extent, co-determined the evolution of disposable incomes of Belgian households on one hand, and their incentives to work on the other. In this paper we assess equity and...

We present an exercise in empirical optimal taxation for European countries from three areas: Southern, Central and Northern Europe. For each country, we estimate a microeconometric model of labour supply for both couples and singles. A procedure that simulates the households' choices under...

Policy makers are generally interested in both the anti-poverty impact and the efficiency of reforms. To connect these two dimensions, I measure the poverty gap change per unit of net revenue that tax-benefit reforms produce. To isolate the impact of reforms and account for labour supply...

We use a behavioural microsimulation model embedded in a numerical optimization procedure in order to identify optimal (social welfare maximizing) tax-transfer rules. We consider the class of tax-transfer rules consisting of a universal basic income and a tax defined by a 4th degree polynomial....

This paper focuses on the study of the effects on social welfare generated by the scheme of joint taxation of the Spanish Personal Income Tax (PIT), whose peculiarity linked to its condition of optionality, allows the minimization of households' tax bill. Different scenarios are simulated using...

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...

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 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...
