This note describes how the counterfactual datasets in the working paper by Lastunen et al. (2021) have been reweighted, for each country analysed, to the ‘pre-crisis’ time point of 31 March 2020. The procedure consists of five main steps. The note...
This technical note presents a modelling approach used in Lastunen et al. (2021) where tax and benefit policies are scaled to reflect their actual duration during a single calendar year. It can be applied to tax-benefit microsimulation models...
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...
This study analyses the impacts of indirect tax benefits policy reforms on income distribution and poverty in Tanzania by applying a standard static microsimulation model TAZMOD v1.8. The simulations model two indirect tax reforms involving changes...
This paper makes use of tax–benefit microsimulation techniques to quantify the distributional effects of COVID-19 in Ecuador and the role of tax–benefit policies in mitigating the immediate impact of the economic shocks. Our results show a dramatic...
In this paper we explore South Africa’s personal income tax system using two microsimulation models. The first, SAMOD, simulates personal income tax and social benefits using a dataset derived from the nationally representative National Income...
Household incomes in Ecuador were badly hit by the pandemic, despite the government’s emergency grant to families. H Xavier Jara Tamayo (University of...
This note, with emphasis on VAT and excise taxes, illustrates how indirect taxes are modelled in the context of GHAMOD, a tax-benefit microsimulation model for Ghana. GHAMOD is similar to the EUROMOD base platform, and its built-in Statistics...

This technical note has been produced alongside a WIDER working paper assessing the effects on income inequality and income tax simulations of adjusting top incomes of employees in survey data based on administrative tax records in Ecuador. The paper...
This note has been produced alongside a WIDER working paper assessing the effect of the Unemployment Insurance benefit on income protection in Ecuador. The aim of this note is to describe the methodology used to assess the effect of the Unemployment...

Using SAMOD, a tax-benefit microsimulation model for South Africa, this paper examines the joint distributional impact of the increase in the value-added tax (VAT) rate and increases in benefit amounts in 2018. Although poverty and inequality did not...
This paper analyses the impacts of indirect tax policy reforms on income distribution and poverty in Tanzania by applying a standard static microsimulation model TAZMOD v1.8. The simulations model two indirect tax reforms involving changes to the...
This paper assesses the effects on poverty and inequality of the alternative targeting approaches that Zambia’s Social Cash Transfer programme could take as its expansion continues during the period of the country’s Seventh National Development Plan...

Redistributive systems in Africa are still in their infancy but are constantly expanding in order to finance increasing public spending. This paper aims at characterizing the redistributive potential of six African countries: Ghana, Zambia...

Part of Journal Special Issue SOUTHMOD: Modelling Tax-benefit Systems in Developing Countries
This study evaluates which type of benefit—a universal benefit, a proxy mean-tested benefit, or a categorical benefit— better cushions the poverty effects of income shocks in a developing economy. We compare the effectiveness of the three benefit...
This report documents COLMOD, the SOUTHMOD micrososimulation model developed for Colombia. It describes the different tax–benefit policies in place, how the microsimulation model takes advantage of these different provisions, and the database on...
Establishing an equitable and efficient tax system is essential for reducing poverty, combating inequality, and fostering sustainable economic growth. Rwanda’s government has recognized this and implemented significant changes to the personal income...
SOUTHMOD tax-benefit microsimulation models may in some cases oversimulate taxes or benefits, generating greater expenditure, a greater number of beneficiaries, or greater amounts of taxes or taxpayers than reported in administrative data. Drawing on...
This report documents RWAMOD, the SOUTHMOD model developed for Rwanda. This work was carried out by UNU-WIDER, SASPRI, and the Rwanda Revenue Authority (RRA). The results presented in this report are derived using RWAMOD version 1.1, which is part of...
This paper analyses the effectiveness of tax-benefit systems in reducing poverty and inequality across 13 countries in the Global South. Using national survey data and tax-benefit microsimulation models from the SOUTHMOD project, we provide a cross...
The debate over universal basic income (UBI) has gained traction in the developing world in recent years. We analyse the effects of four UBI schemes on poverty and inequality measures during normal times and times of crisis in Uganda and Zambia. We...
South Africa has a progressive broad-based personal income tax system with relatively few tax expenditures. The two most important are the medical contribution plus additional tax credits for medical expenses, and the deductions allowed for...
The tax-benefit microsimulation model developed for Mozambique, MOZMOD, has proved to be valuable in analysing the impacts and budget implications of...
