Price concentration studies investigate the relationship between market concentration and price levels. They are increasingly used in the mobile telecom industry. This paper provides a detailed account of the limitations of such studies. In addition, it proposes a specific approach in order to account for quality differences across countries, which are likely important when explaining price differences. When applying our approach to European mobile telecom markets from 2003 to 2012, we find that there is no positive relationship between concentration and prices and some indications that the relationship may be negative.

This paper analyses how different types of access regulation to next generation networks affect investments and consumer welfare. The model consists of an investment stage with uncertain returns and subsequent quantity competition. The access price is a function of investment costs and the regulatory regime. A regime with fully distributed costs or a regulatory holiday induces highest investments, followed by risk-sharing and long-run-incremental cost regulation. Risk-sharing creates most consumer welfare, followed by regimes with fully distributed costs, long-run-incremental costs and regulatory holiday, respectively. Risk-sharing benefits consumers as it combines relatively high ex-ante investment incentives with strong ex-post competitive intensity.
