Market structure and competition in digital markets

PhD Project Outline

Digital markets are often two- or multi-sided and online platforms are the main intermediaries. Strongnetwork effects but also economies of scale and scope produced by low (or zero) marginal costs and the use of data are drivers of concentration in these markets.

Our interest relies on the fact that the market structure in digital markets differs from that of traditional monopolistic or oligopolistic markets. Digital platforms typically put together sellers and buyers. The two- (or multi)-sidedness of online platforms brings in new reasons for platform market structure. In certain situations, the market structure of platform markets is the result of competition among sellers. Intense product/service competition between sellers can direct sellers towards different platforms to soften competition. The opposite is true if competition between sellers is soft. The behaviour by sellers has implications for the platform market structure. There are also other reasons.

This is an area that is currently under-researched. The objective of the research is to conduct an empirical analysis using various alternative methodologies and levels of analysis.

Research Team: You would be working with Dr. Franco Mariuzzo and Dr. Michael Kummer (and possibly other IO economists in the school.)
