This paper develops a new imputation methodology applied to missing incomes values in PNAD. PNAD is the main Brazilian household survey, but it has no imputation. The imputation process starts by fitting regression models applied to different income sources considering the complex sampling...

This paper explores the impact of the first wave of the COVID-19 pandemic in South Africa on income poverty and inequality in South Africa. Using a static tax-benefit microsimulation model with input datasets that were adjusted to reflect people's earned incomes just before the pandemic (March...

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...

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...

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 schemes on poverty first conceptually and then by...

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...

A key aspect defining the contemporary income distribution is the (increasing) share the top holds compared to the rest. This paper shows that income concentration increases towards the very top of the distribution, while the shares the middle- and upper-middle-income groups hold, remain stable...

This paper presents preliminary evidence of the annual global income distribution since 1950 using a new integrated dataset that aggregates standardized country income distributions at the percentile level estimated from various sources in the World Income Inequality Database. I analyse the...
