The demand for faster broadband access is a key driver of fiber-to-the-home (FTTH) adoption and fixed broadband competition, and therefore of co-investment. This paper assesses the effects on FTTH adoption and competition of FTTH co-investment. Co-investment had indeed been endorsed in the European Electronic Communication Code as a relevant option for conciliating investment and competition.

We evaluate the impact of mobile operator mergers on the unit price of data and voice by using country-level observations on retail revenue for data, cellular data traffic, retail revenue for voice, and outgoing voice minutes. Using a difference-in-differences estimation strategy, we estimate the effect of operator merger by comparing the difference between the non-merging countries and the merging countries before and after the introduction of the operator merger.
