The problem of debt bias can be tackled through either disincentivizing the use of debt financing or incentivizing the use of equity financing. Considering the South African context - in which many firms are highly leveraged and the marginal effective tax rates for using debt financing are...

This paper examines the distributional impacts of agricultural policies versus those of cash transfers using a tax-benefit microsimulation model for Zambia for the policy year 2020. The analysis also considers the behavioural impacts of input subsidies and social cash transfers. The results...

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...

We evaluate a major personal income tax reform in Uganda that came into effect in 2012-13, contributing to the scarce literature on the effects of personal income tax reform on employees' income in a low-income country in Africa. The reform increased the tax-free lower threshold, increased tax...

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...

This paper examines the measurement of social welfare, poverty and inequality taking into account features that have been found to be important welfare determinants in behavioural economics. Most notably, we incorporate reference-dependence, loss aversion and diminishing sensitivity - aspects...

This paper evaluates the impact of an integrated rural development programme on farming techniques and food security in the Gaza area of rural Mozambique. We examine the impact of a group-based approach, in a country with few impact evaluations of technology adoption in farming. Using...

This paper analyses the effectiveness of tax-benefit systems in reducing poverty and inequality across 13 countries in the Global South. Using national survey data and tax-benefit microsimulation models from the SOUTHMOD project, we provide a cross-country perspective on the redistributive...

Rising levels of income inequality and tight government budgets have spurred discussions in many developing nations about how to appropriately tax high-income earners. In this paper, we study taxpayer responses to an increase in the top marginal tax rate in South Africa, drawing on exceptionally...
