Market Power in Telecommunications and Harmonization of Ex-Ante/Ex-Post Regulations

In this policy paper, I investigate how to harmonize regulatory and competition policies in telecommunications. Increased competition and digital convergence have eroded the grounds for market power regulation in this industry, while there arise many cases without clear regulatory implications. I carefully check traditional arguments for ex ante market power regulations and conclude that many of them are no longer valid. For a few exceptions, simple price cap or essential facilities regulations would suffice. In the remaining part of the paper, I also suggest how to revise the market power test process to reflect ex post approach.
