A large informal sector is a challenge for developing countries building up social protection systems. Expanding social safety nets reduces poverty, but financing them can increase the tax burden, potentially reducing availability of formal sector...
The aim of this paper is to explore the redistributive effects of taxes and benefits in Ecuador using two different approaches: direct use of reported taxes and benefits in household survey data, and use of simulated taxes and benefits obtained from...
In this paper, we analyse two specific policies that make up the National Care System, a social policy being implemented in Uruguay. Through the calibration of a static tax benefit model, we estimate the distributive impact of the expansion of...
The University of Tampere is participating in an international project in which a microsimulation model is being drafted for the evaluation of the...
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 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 world has faced an increasing number of global shocks that have resulted in large and unpredictable changes in global prices, particularly of food. These increases, coupled with the negative impacts of shocks to economic growth, have had damaging...

As greenhouse gases once again climb to record levels, countries are under pressure to make the move to a low-carbon economy. Policies that move in...
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...
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 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 paper assesses the feasibility of developing a tax and benefit microsimulation model in Rwanda. Tax-benefit microsimulation can be used to explore ways in which national development goals can be achieved in a cost-effective manner, and to assess...
