This study analyses the progress of market concentration in OECD member states' mobile telecommunications markets and evaluates the relationship between market concentration and performance. Using annual panel data from 24 OECD member states for the 1998-2011 period, the study estimates...

First-mover advantage may be more remarkable in the inherently oligopolistic mobile telecommunications market. This study evaluates the impact of market experience and competition on market share and profitability in mobile markets. Specifically, the study estimates regression equations for...
