1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

introductionTobacco taxation is only effective in reducing consumption when it is translated into higher prices. This study aims to investigate to what extent the tobacco industry (TI) passes tax increases over to consumers by increasing the retail price of cigarettes in 12 sub-Saharan African (SSA) countries.

methodsAfrican Cigarette Prices Project and WHO's Global Tobacco Epidemic Reports data were used to calculate the rate of tax pass-through by decomposing the retail price of cigarettes into tax and net prices between 2016 and 2020. Percentage change in net price was used to identify industry pricing behaviour, in both packs and single-stick sales. TI pricing strategies were examined by country, producer type, producers, and cigarette price segment.

resultsThere were mixed TI strategies, with taxes primarily overshifted (Botswana, Madagascar, Tanzania, Zimbabwe), undershifted (Ethiopia, Lesotho, Mozambique, Namibia, South Africa, Zambia) or a mix of both (Malawi, Nigeria). The detail varied between countries, over time, and between the different brands/segments offered. Patterns for single-stick sales were broadly similar to that of packs but with some differences observed in particular countries/years. Pricing strategies for the various transnational tobacco companies and domestic producers were similar but the changes in net price for the latter were larger. The country tax level/type and the size of tax change did not seem to be an obvious influence.

conclusionThis paper provides an overview of TI pricing strategies in response to tax increases in SSA. Governments must monitor how the TI responds to tax changes to ensure that tax increases are effective in impacting price.
