The award of the Nobel Prize in Economics to Professor Jean Tirole in 2014 has generated intense interest about his brainchild theory of two-sided markets. Against this background, this paper explores whether there is such a thing as a unified theory of two-sided markets and whether the...

This paper seeks to understand the competitive impact of State restrictions to M&A transactions which target domestic corporations.
