An important and timely contribution to rapidly growing competition law in South Africa, this study meets the need for critical evaluation of the developments in the field since the Competition Act came into force in 1999. Chapters cover vital questions ranging from broad policy considerations to technical issues in the main areas of competition evaluation, namely merger assessment, abuse-of-dominance enforcement, and the detection and prosecution of cartels. The book reflects on the maturing South African competition law regime and discusses a framework for promotion competition in electronic communications; vertical arithmetic and its application in vertical mergers; price discrimination in input markets; the empirical differences between collusion, parallelism, and competition; and the role of information exchange in facilitating collusion.
