Chapter 4: Characteristics of digital markets and their implications for the assessment of market power

Beata Mäihäniemi


This chapter evaluates the characteristics of digital markets and their implications for the assessment of market power. In particular, it defines network effects and other phenomena connected to these such as the two-sidedness of online platforms that attract users with various free services and literally ‘sell’ these users to advertisers. Finally, it ponders upon potential competition and innovation and the role they can play in the environment of information intermediaries, as the competition in such markets is in innovation and not in product substitutability.
