The quality of data on employment income is explored using Tanzanian and Zambian household survey datasets. The extent of missing and implausible income data is assessed and four different methods are applied to impute missing or implausible values. The four imputation methods are also applied...

Although the effect of fiscal drag is well studied in the industrialized world, empirical evidence from developing economies remains limited. Against this backdrop, this study aims to explore the effect of fiscal drag on income distribution and work incentives. To this end, the study employs...

In this paper we explore options for augmenting South Africa's personal income tax revenue using two microsimulation models: PITMOD simulates the personal income tax system and is underpinned by a dataset comprising a full extract of anonymized individual-level administrative tax data; and SAMOD...

This paper studies the redistributive and revenue effects of bracket creep in Germany under various inflation scenarios and evaluates the feasibility to charge a rich tax to fight bracket creep for the income distribution in 2009. Using a tax micro-simulation model developed for the newly...

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...

In Germany, there is an ongoing debate about how to increase the efficiency of the social security system and especially its financing. The aim of this paper is to simulate different financing systems for Germany. The introduction of a Liberal British or the Southern Greek financing system...

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...

This paper analyses how inflation-induced erosions of nominally defined amounts built into relevant tax rules (“bracket creep”) alter distributional and revenue-generating properties of income taxes and social insurance contributions. Using a multi-country tax-benefit model, it provides...

This paper gives an international comparison of the redistributive effect of personal income taxes in the 15 countries of the EU, using the European tax-benefit model EUROMOD. We focus on the effect of personal income taxes, social insurance contributions and other direct taxes. We present the...

In this paper we analyse how income taxation interferes with the logic and aims of the social security system. We investigate the distributional effects of the tax treatment of social benefits, and more specifically of old age pensions and unemployment benefits. We present a brief overview of...
