Researchers

Prof. Corné Van Walbeek

Director of REEP and Professor, School of Economics, University of Cape Town

Corné is a Professor at the School of Economics at UCT, and the Director of REEP. His research interests are primarily in the economics of tobacco control, and in particular how changes in the excise tax on tobacco products can affect cigarette consumption. He developed the Tobacco Excise Tax Simulation Model (TETSiM), which is often used to determine the likely fiscal and consumption impact of a change in the level or the structure of the excise tax. His research has focused on the estimation of price elasticities of demand, how excise tax increases impact the poor, changes in smoking by different demographic groups over time, and the industry’s reaction to changes in the tobacco excise tax. In recent years his research has been focused on measuring illicit trade. In addition, Corné also has a lively research interest in the economics of alcohol policy and sugar-sweetened beverages.

Zunda Chisha

Research Officer and the Programme Director of the WHO FCTC Knowledge Hub on Tobacco Taxation

Zunda is a Research Officer at REEP, and the Programme Director of the WHO FCTC Knowledge Hub on Tobacco Taxation. He is currently a PhD candidate focusing on the economic interactions of alcohol and tobacco use. His PhD topic aims to investigate the nature of the relationship in the consumption of the two products and their effects on the South African population at household and individual level. He is also involved in a project on the impact of cigarette tax increases on the illicit cigarette market in low- and middle-income countries. Zunda holds a Bachelor’s degree in economics from the University of Zambia, and a Master’s degree in health economics from UCT. As a health economist with experience in public health, program implementation and research, Zunda is skilled in data management with expertise in qualitative data analysis and modelling applications.

Nicole Vellios

Research Officer

Nicole is a Senior Research Officer at REEP. She graduated with a PhD in economics from UCT in 2022. Nicole’s PhD thesis focused on the economics of quitting cigarette smoking in South Africa. Using survival analysis techniques applied to data from the National Income Dynamics Study and price data from government documents, she found that an increase in the price of cigarettes is significantly associated with quitting behaviour. By surveying UCT students, and showing them various cigarette packs with different attributes, she found that plain packaging (where all branding is removed and graphic health warnings are printed on cigarette packs) would reduce the demand for cigarettes. Since access to cheap, illicit cigarettes could reduce the effectiveness of excise tax increases and plain packaging in reducing smoking prevalence, she measured the size of the illicit market. She found that, since 2010, illicit trade increased sharply, and accounted for about a third of the total market in 2017. Updated estimates show that illicit trade in 2022 accounted for around 60% of the total market. Nicole has published papers on tobacco, alcohol, cannabis, and student tuition fees at UCT.
