, GASTCOLLEGE 1: COMPETITION POLICY & DIGITAL INTERMEDIATION PLATFORMS
INTRODUCTION
Meneer die Dekaan Prof Branson, Prof Buts
We will be delving into the economics and competition policy of digital commerce, considering multiple
jurisdictions, but often looking at South African examples.
South Africa: a different perspective -> Reflecting over the past few months on what insights a South
African can offer a European audience interested in digital platform issues, has led me to three
conclusions.
• One, that South African digital markets offer an alternative setting which shares many of the
characteristics of, and trends in, digital commerce in Europe and the US, but with different
players. This commonality challenges popular notions of ‘bad’ Big Tech and instead points to
universal economic principles at work in these markets.
• Second, that for all the discussion here in Europe about the centrality of the digital world for the
future of the continent, the stakes are even higher in South Africa and other developing
countries. How South African policymakers deal with broader developmental concerns in digital
policy is a harbinger of future approaches elsewhere or - at the least - a cautionary example of
what to do or to avoid.
• Third, that if competition is possible in South African digital markets, it is possible or can be
fostered elsewhere. As we will discuss, scale is typically a major challenge in countries with small
markets. If mature South African digital markets can support multiple players or otherwise
maintain dynamism, it offers hope that monopoly is not predetermined in the digital world.
So let us, slowly, move into the world of digital intermediation platforms, which are the focus of this
lecture series.
