New study: Ex-post Analysis of the TeliaSonera-Chess 2005 Merger

February 16, 2021

Copenhagen Economics is proud to announce the publication of an ex-post analysis of the 2005 TeliaSonera-Chess merger in the Norwegian mobile telecommunication market.

Ex-post assessments remain an important tool in evaluating the efficiency of competition policy and, in a broader sense, serve a complementary function to the competitive assessments of actual cases.

In our recent study commissioned by the Norwegian Competition Authority, we explore the flexibility of the difference-in-difference and the control group methods to identify the lack of impact of the 2005 TeliaSonera/Chess merger on retail prices. Through such rigorous investigation, our findings confirmed that there is no evidence of the merger increasing prices.
