This book addresses the question of how competition authorities assess mergers in the Information Communication Technology (ICT) sector so as to promote competition in innovation. A closer look at the question reveals that it is far more complex and difficult to answer for the ICT, telecommunications and multi-sided platform (MSP) economy than for more traditional sectors of the economy. This has led many scholars to re-think and question whether the current merger control framework is suitable for the ICT sector, which is often also referred to as the new economy.
