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...

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 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 individual-level administrative tax data; and SAMOD...

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 Dynamics Study survey. The second, PITMOD, simulates...

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 distributional analysis of consumption taxes is useful for establishing the welfare impact of tax policy. This paper uses the UGAMOD microsimulation model to establish the tax incidence and welfare impact of excise duty in Uganda. The results reveal that households in the top deciles pay...

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 increase overall, the poorest still saw a...

This working paper explores the feasibility of developing a tax and benefit microsimulation model in Zanzibar using the EUROMOD microsimulation software. We review Zanzibar's tax and benefit arrangements and the potential household survey dataset that would underpin the model, and we conclude...

The provision of a universal old age pension is increasingly recognized as an important instrument for strengthening and extending social protection. A growing number of emerging economies, including East African countries, are introducing universal old age pensions to guarantee at least a basic...

This paper assesses the effects of public policies on income taxes and benefits in six African countries. The comparative analysis focuses on the distribution and composition of incomes and assesses the effect of these policies on inequality and poverty. The results are based on newly developed...
