Abstract: This article shows that mark-ups are significantly higher in South African manufacturing industries than they are in corresponding industries worldwide. We test for the consequences of this low-level of product market competition on productivity growth. The results of the paper are that high mark-ups have a large negative impact on productivity growth in South African manufacturing industry. Our results are robust to three different data sources, two alternative measures of productivity growth, and three distinct measures of the mark-up. Controlling for potential endogeneity of regressors does not eliminate the findings. The definitive version is available at
