We examine the distributional effects of the COVID-19 pandemic and associated tax-benefit measures in seven sub-Saharan African countries, focusing on the onset of the crisis.We evaluate impacts on disposable incomes, considering variations across...
This report documents GHAMOD, the SOUTHMOD model developed for Ghana. The report describes the different tax-benefit policies in place, how the microsimulation model picks up these different provisions, and the database on which the model runs. It...
Assessing tax gaps—the difference between the potential and actual taxes raised—plays a vital role in achieving positive domestic revenue objectives through improved and reformed taxation. This is particularly pertinent for growth outcomes in...
Improving tax collection is essential if developing economies are to avoid over-reliance on external donor funds and loans. Revenue authorities in the Global South have recently adopted new policy tools to improve domestic revenue mobilization...
This paper calculates automatic stabilization in Ghana, South Africa, and Ecuador to explain income cushioning amid income and demand shocks. Fiscal policies within these countries are also stress tested to gauge welfare contingencies and insurance...

This paper analyses the distributional effects of the COVID-19 pandemic and related tax-benefit measures in 2020 in a cross-country comparative perspective for five African countries: Ghana, Mozambique, Tanzania, Uganda, and Zambia. We first estimate...
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...
