– The case of Girinka in Rwanda
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 an example of a social benefit policy in Rwanda...

This technical note describes the compilation of a 2019 Social Accounting Matrix (SAM) for South Africa. SAMs are economy-wide databases that are used together with analytical techniques to strengthen evidence-based policy analysis. This SAM is based on a supply table and a use table for 2019...

Introduction Only recently has the importance and potential of behavioural sciences been recognized as a critical tool to achieve the Sustainable Development Goals (SDGs). This long-awaited recognition comes from the highest levels of the United Nations, with the Secretary-General recently issuing a...
Technical Note

This note describes methods to derive employment-to-unemployment transition shares across industries during the COVID-19 pandemic and to use these shares in SOUTHMOD tax-benefit microsimulation models to adjust relevant labour market variables. The first method entails the derivation of industry...
Technical Note
pdf
This technical note presents one of the modelling approaches used in Jara and Rattenhuber (2022) to estimate formal employment elasticities, namely the estimation of a discrete choice model of labour supply with informal employment. The approach makes use of ECUAMOD, the tax-benefit model for...
Background Note
pdf
IntroductionThe South African youth wage subsidy started in 2014 to increase employment and create jobs for low-wage youth. The subsidy was temporarily raised in value and expanded to reach more workers due to the COVID-19 pandemic. During the lockdown period, the government used the subsidy to curb...
Technical Note

This technical note describes the Uganda Revenue Authority (URA) firm panel, which is constructed from administrative corporate income tax (CIT) returns and firm registration data for the financial years 2013/14–2019/20. The panel dataset contains over 300 variables, which allow the user to study...
Technical Note
pdf
Agricultural subsidies may have significant productive and distributional consequences, and policy-makers need to be able to assess these impacts as a part of the overall tax and benefit policy. Microsimulation models offer a tool for such analysis also in developing countries, but their coverage...
Technical Note
pdf
This note provides an overview of available cross-country data on ethnic conflict, tensions, and protests. First, it documents the steps taken in the selection of 16 different relevant data sources, before they are briefly described, and their distinct aspects are highlighted. Second, it includes...
Technical Note

This technical note is the third in a series based on the UNU-WIDER Government Revenue Dataset (GRD). The preceding notes have described in detail the variables contained within the GRD and the source selection procedures. In this technical note, we present the in-depth country-specific notes that...

– CIT-IRP5 panel v4.0
We update Kreuser and Newman’s (2018) total factor productivity estimates for the South African manufacturing sector using administrative data from 2009–17. We use standard implementations of the Ackerberg et al. (2015) and Wooldridge (2009) productivity estimators and introduce an implementation of...
Technical Note
pdf
This note sets out two different methods on how to adjust incomes in the microdata underlying the standard SOUTHMOD models to reflect a sudden shock, in this case the COVID-19 shock, as done in the accompanying working paper by Lastunen et al. (2021). The note first describes how industry-specific...
Technical Note
pdf
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 implemented in the EUROMOD software. The method is...
Technical Note
pdf
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 forms part of a series of technical notes that...
Technical Note
pdf
This note, which forms part of a series of technical notes that complement Lastunen et al. (2021), reports the approach used to derive shocks to household expenditures from shocks at the individual-level labour incomes. Its structure is composed by six different parts that describe the technique...
Technical Note

This note has set out several data processes that have been undertaken using the income data in dataset(s) that underpin SAMOD. Section 1 describes various data-cleaning steps that were undertaken when preparing the LCS 2014/15 as an underpinning dataset for SAMOD. Part 2 elaborates on the process...

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 Insurance through the simulation of transitions...
Technical Note

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 Presenter Tool supports simple analyses of ex-ante policy...

– The South African experience
Introduction: data for development Globally, one of the key factors associated with increasing use of data to inform policy-making has been the increased availability of new administrative data sources. In 2014, the National Treasury of South Africa (NT) pioneered the development of new tax...
