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...

Die in Aussicht gestellten Steuererleichterungen sind das beherrschende Thema der ersten Wochen nach Amtsantritt der neuen Bundesregierung. Die vorliegende Studie enthält eine Simulation der mutmaßlichen Effekte einer Umsetzung des von der FDP vorgeschlagenen Stufentarifs und Bürgergelds auf...

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...

The income tax rate structure introduced in 2007 was changed in 2009. The income tax rates will be lowered in 2010, too. The effects on the wage income tax revenues and on the incentives to work are analyzed. It turns out that bracket creepʺ will remain a problem in Germany. -- Wage income tax...
