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 presents an evaluation of the tax-transfer treatment of married couples in 15 EU countries using the EUROMOD microsimulation model. First, we show that many tax-transfer schemes in Europe feature negative jointness defined as a situation where the tax rate on one person depends...

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...

Due to limited access to foreign savings after the 2008 crisis, transition economies are forced to rely more on domestic savings in financing their growth. In that respect, it is often argued that the government should use tax policy to encourage domestic savings. Since the personal income tax...

The Australian income tax and transfer system has undergone considerable reform since the mid 1980s. As a number of commentators have pointed out, one impact of reforms to cash transfers for families, as well as of some reforms to direct taxes, has been the evolution of a defacto system of...

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...

Over the last few years concern for income inequality in European countries has increased remarkably. In this context, taxation is an important redistributive instrument and we investigate the redistributive role of direct taxes. We focus on the EU-15 countries and the evolution over the period...

The distributional impact of policy changes is usually considered in terms of equivalised household income, assuming that each individual within the household is being affected in the same way, as a result of complete income pooling. The aim of this paper is to extend this approach by...
