First mover advantages in mobile telecommunications: Evidence from OECD countries

Posted by D. Daniel Sokol

Johannes Muck (Dusseldorf Institute for Competition Economics) and Ulrich Heimeshoff (Dusseldorf Institute for Competition Economics) discuss First mover advantages in mobile telecommunications: Evidence from OECD countries.

ABSTRACT: We explore the existence of first mover advantages in mobile telecommunications markets. Building on a data set comprising monthly penetration rates, market concentration, number of active operators, and market shares of 90 followers from 33 OECD countries, we estimate a dynamic growth model. Our analysis delivers five key results. Regarding a follower's longrun market share, we observe that (1) the penetration rate at the time of market entry exerts an inverted u-shaped effect, suggesting the existence of an optimal time for issuing additional licenses for mobile network operation; (2) the concentration rate at market entry exerts a positive effect, implying that it is easier for followers to enter a more concentrated market; (3) both the number of active operators at market entry and the number of currently active operators have a negative impact. Furthermore, we find that a follower's rate of convergence to the long-r! un market share is (4) negatively influenced by the current market concentration and number of active operators; (5) negatively affected by changes in the penetration rate since market entry, which strongly indicates the presence of substantial first mover advantages for pioneering network operators.
