In the microsimulation literature, it is still uncommon to test the statistical significance of results. In this paper we argue that this situation is both undesirable and unnecessary. Provided the parameters used in the microsimulation are exogenous, as is often the case in static...

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...

The adverse distributional effects of a flat tax are well known and have been documented by empirical research in several countries, including Belgium. Advocates of the flat tax argue, correctly, that many of these studies do not take into account agents' behavioural reactions and possible feed...

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...

The paper focuses on the support given through tax and benefit systems to families with children and addresses how the size and impact on the income distribution of this kind of support can be accurately measured. While such support is usually measured in rather narrow terms by adding up the...

Tax and benefit systems in the enlarged EU vary significantly in size and structure. We examine how taxes and benefits shape income distributions in 19 EU countries, focusing on the differences between Western European countries (EU15) and Eastern European countries (Estonia, Hungary, Poland,...

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...

International comparisons of inequality based on measures of disposable income may not be valid if the size and incidence of publicly-provided in kind benefits differ across the countries considered. The benefits that are financed by taxation in one country may need to be purchased out of...

This paper evaluates income distributions in four European countries (Austria, Italy, Spain and Hungary) using two complementary approaches: a standard approach based on reported incomes in survey data, and a microsimulation approach, where taxes and benefits are simulated. Given that benefit...

As unemployment rises across the European Union (EU) it is important to understand the extent to which the incomes of the new unemployed are protected by tax-benefit systems and to assess the cost pressures on the social protection systems of this increase in unemployment. This paper uses the EU...
