This study explores the social protection and humanitarian emergency nexus in Zambia. Drawing on 25 stakeholder interviews and relevant literature sources, it seeks to (i) identify the social protection needs experienced in the country in the context of different shocks and crises; (ii) elucidate...

Zambia’s reliance on rain-fed agriculture makes its economy and population highly vulnerable to frequent droughts and irregular rainfall. This paper assesses the role of social protection, specifically the Social Cash Transfer (SCT) program, in mitigating drought-induced poverty and consumption...

This paper exploits several waves of two major nationwide representative surveys to document the impacts of climate shocks on individuals and households in Zambia. We merge these datasets with historical precipitation and temperature data at the district level. First, we show the gendered effects of...

Low-income countries face the combined challenges of climate shocks and limited domestic revenue mobilization, yet these issues are rarely studied together. This paper provides new evidence on the impact of climate shocks on firm performance and tax revenue in a low-income country context, using...

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...

This paper explores two policy interventions in Zambia, a minimum wage hike in 2018 and an upward revision in the first kink in the progressive income tax schedule in 2017, to examine and compare the impact of minimum wage and tax kink changes on wages and the earnings distribution in the formal and...

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...

We investigate the behavioural responses of individual taxpayers to changes in marginal personal income tax rates applying empirical bunching methodology to tax administrative data from Zambia over the period from 2014 to 2021. We find evidence for excess bunching at the first kink in the tax...

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 income groups; assess the effectiveness of tax...
