- ItemOpen AccessThe impact of cigarette excise tax Increases and harmonisation in the East African community(2013) Posen, Jodie; van Walbeek, CorneThis paper proposes a model that can be used to predict the likely impacts of tobacco tax increases and harmonisation in the East African Community. The model has five sections, one for each EAC country. These sections consider different cigarette market segments based on tax or price differentials. The model can therefore calculate the likely effects of excise tax increases and harmonisation on the retail selling price of cigarettes, cigarette consumption, government revenue and industry revenue for each individual country and for the EAC as a whole.

I first analysed the trend in CSD and fruit juice affordability between 2005 and 2018. I subsequently estimated the own-price, cross-price and income elasticities of sugar, CSDs, chocolate drinks, milk and sachet water for Nigeria in 2013, 2016 and a pooled sample. I used the relative income price to examine CSD and fruit juice affordability over time in Nigeria for both off-trade and on-trade consumption. For estimating the own-price, cross-price and expenditure elasticities, I used the Nigeria Household Survey, Panel (2013 and 2016) data, using the Almost Ideal Demand System. I applied Deaton's unit value model and used unit values as prices and used the Heckman procedure to correct for selection bias. For CSDs, the own-price elasticities ranged from - 0.8 to -1.8. All income (approximated by household expenditure) elasticities were positive implying all the commodities are normal goods. The income elasticity of demand lies at approximately 0.4 for CSDs. The results suggest that Nigeria can curb the consumption of excess sugar, in particular excess sugar in CSDs, by raising the price by implementing an excise tax on the sugar content in CSDs. Future research should estimate the health gains and government revenue that can be generated from such a tax. Such estimates are crucial to motivate for a sugar tax.

Assessing the Economic Case for Investing In, or Divesting From, Tobacco Companies(2022) Evans, Timothy; van Walbeek, CorneConsidering that wealth-maximising investors are generally not willing to sacrifice financial returns in favour of ethical considerations, this paper seeks to investigate the economic case for investing in, or divesting from, tobacco companies. After analysing the financial performance of some of the world's largest tobacco companies, this paper finds that the demand for traditional tobacco products (e.g., cigarettes) is in decline due to tightening tobacco regulation and increasing health awareness, and as a consequence all but one of the companies analysed experienced declines in tobacco sales (in dollar terms) over the period FY2014- FY2020. In addition, the results show that the tobacco companies in question are becoming increasingly inefficient at generating profits, and that market sentiment towards these companies' growth potential has diminished. Putting aside the possibility of tobacco companies entering the cannabis market, the evidence suggests that the future profitability of these companies depends on whether they will be able to increase the sales of Next Generation Products (“NGPs”) to significantly offset the decline of traditional tobacco sales, which they have not yet been able to do. Regulation could also dramatically affect the future success of NGPs. Given that financial markets tend to reward the stock prices of fast-growing firms, and given tobacco companies' disappointing revenue growth, the economic case for investing in tobacco companies is currently characterised by (significantly more) uncertainty and risk. In other words, it is increasingly unclear whether tobacco companies will be able to achieve growth in future; as a result, their shareholders could incur capital losses.
