Microsimulation models of the LOTTE system are key tools for tax policy-making in Norway and are extensively used in the budget process. The aim of this paper is to give an overview of the different modules in the LOTTE family - a non-behavioral tax-benefit model for personal income tax...

Die Komplexität des deutschen Steuersystems hat in den vergangenen Jahren immer wieder Verbesserungsvorschläge hervorgerufen. In diesem Beitrag analysieren wir den von Manfred Rose vorgelegten Reformvorschlag eines Fünf-Stufen-Tarifs in Verbindung mit einer Reform der steuerlichen...

This paper provides an account of a South African tax-benefit microsimulation model - SAMOD - which has been developed for use by government over the past ten years. The two datasets that underpin the current version of SAMOD are introduced, and the model's tax and benefit policies are described...

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...

Given the increased availability of survey income data, in this paper we analyse the pros and cons of alternative data sets for static tax-benefit microsimulation in Italy. We focus on all possible alternatives, namely using (a) SHIW or (b) IT-SILC data using a consistent net-to-gross...

This paper provides an account of a Nambian tax-benefit microsimulation model - NAMOD - which has been developed for use by government. Following a section on the importance of social security in Namibia and recent related studies, the paper outlines the tax-benefit policies that are included...

In this paper we explore the income data in two surveys that underpin a South African tax-benefit microsimulation model. The simulated taxes and benefits using each dataset are compared with each other and with administrative data for a common time point. We explore discrepancies between the...

During the last decade, research on income inequality has paid special attention to top income earners. At the same time, top marginal tax rates on upper income earners have declined sharply in many OECD countries. Discussions are still open on the relationship between the increase of the income...

This paper analyzes the effect of the introduction of a final withholding tax on capital income on the progression of the German income tax. As previous literature shows, even with synthetic income taxation, tax progression was strongest in the middle of the income distribution, and decreased...
