UCT study links import duties to higher pasta and chip prices
Professor Lawrence Edwards and Dr Godfrey Kamutando of the University of Cape Town found that anti-dumping duties raised frozen chip prices by 4.7% on average. Pasta prices rose a combined 9% when higher tariffs and anti-dumping duties applied.
The peer-reviewed study, in the South African Journal of Economics, used nearly 63,000 monthly retail price records from Statistics South Africa for January 2010 to April 2022. The effect on chips was larger in metropolitan areas. The researchers estimated the price rises cut household welfare by 0.03% of annual food spending. The study covers only two product groups and counts only direct price effects, not changes in wages or meals eaten out. The South African Reserve Bank funded it.
