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...

The Great Recession and the widespread adoption of fiscal austerity policies have heightened concern about inequality and how well tax-benefit systems redistribute. We examine how the distribution of income in the EU countries which were hardest hit during the recession evolved over this time....

This papers quantifies the redistributive effects on progressivity, poverty and welfare, that would occur if the monetary benefits currently in place in the Spanish system were to be replaced by a neutral alternative in terms of spending, granting a universal basic income (UBI) to everyone. We...

The "Minimum Vital Income" (IMV) constitutes a novelty in the panorama for fighting poverty by guaranteeing minimum incomes after the COVID-19 crisis. This work simulates the distributional and poverty effects of the IMV introduction across Spanish regions using EUROMOD. Our results show that...

Using EUROMOD, we cross-validate two types of micro-data presently available in the Grand-Duchy of Luxembourg, administrative data on one hand and survey data on the other hand. While administrative data, extracted from the recently implemented Social Security Data Warehouse, contain information...

Following the report of the Stiglitz Commission, measuring and comparing well-being across countries has gained renewed interest. Yet, analyses that go beyond income and incorporate non-market dimensions of welfare most often rely on the assumption of identical preferences to avoid the...

Less visible than benefit expenditure, spending channelled through the tax system via tax concessions and advantages can amount to substantial amounts of foregone revenue. In this paper we use EUROMOD, a tax-benefit micro-simulation model covering all EU member states, to investigate the size...

This paper presents the main characteristics of TREMOD, a tax-benefit microsimulation model for the Italian province of Trento (Italy). TREMOD is based upon the EUROMOD platform microsimulation model, and its purpose is to inform local tax and welfare policies. TREMOD is a flexible tool that...
