The flat income tax has become increasingly popular recently, yet its implementation is limited to Eastern Europe. We analyse the distributional and efficiency effects of flat tax scenarios for Western European countries. Our simulations show that flat tax rates required to attain revenue...

We develop and estimate a microeconometric model of household labour supply in four European countries representative of different economies and welfare policy regimes: Denmark, Italy, Portugal and United Kingdom. We then simulate, under the constraint of constant total net tax revenue, the...

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...

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...

In this study, the household labour supply is modelled as a discrete choice problem assuming that preference for leisure and consumption can be described by a quadratic utility function which allows for non-convexities in the budget set. We assess behavioural responses to the significant changes...

Flat tax schemes are popular in Eastern Europe, with an ever increasing number of countries where it is introduced, and yet many other where it is recurringly discussed. Analysing three countries, we show that the design of such schemes largely determines their impact on fiscal revenues and on...

More than half of the EU countries have become poorer and more unequal since the start of the crisis in 2008. Despite lack of timely household micro data, using microsimulation techniques with up-to-date information on policy rules enables us to estimate the direct effect of tax-benefit policy...

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...
