– Comparing the performance of universal basic income in Uganda and Zambia during COVID-19
The debate over universal basic income (UBI) has gained traction in the developing world in recent years. We analyse the effects of four UBI schemes on poverty and inequality measures during normal times and times of crisis in Uganda and Zambia. We use static microsimulation models and nationally...

– Simulation results for Zambia
The COVID-19 pandemic increased public debt and changed the income distribution in many countries. We use a numerical simulation approach to derive optimal nonlinear marginal tax rates for the pre-crisis and crisis periods. We contribute to the literature by examining optimal tax rates numerically...

– Insights from survey and tax administrative data in Zambia
This paper examines how formal firms have been impacted by and recovered from the pandemic by drawing on two distinct but complementary data sources. This is the first attempt to use both survey and tax administrative data to measure the initial decline and subsequent recovery of firm sales and...

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...

– Policy options for a sustainable fiscal regime
Zambia has changed its mineral tax regime repeatedly during the past decades in a bid to raise mineral revenue, but with only modest success. This paper looks at what the country needs to do to create a mining fiscal regime that could sustain operations, boost output, and raise revenues without...

– Simulating potential Cash Plus reforms using MicroZAMOD
A large share of the population in Zambia is living below the national poverty line. To reduce poverty, in 2019, the government initiated the Cash Plus reform, which aims to build on the existing Social Cash Transfer as a floor benefit with additional benefits to take account of the...

– Receiving more, expecting less?
Are candidates who hand out clientelistic goods at election time less likely to provide services once they take office? This paper examines the poor’s expectations of future service provision by candidates who hand out money and other goods versus those who do not. We hypothesize that the poor’s...
