Abstract
Number portability service in the mobile communications market is believed to play an important
role in lowering the switching costs which can increase the level of competition among providers.
The aim of this study was to estimate the switching costs and consumers’ valuation of the number
portability service in the Korean mobile communications market using conjoint analysis and the
stated preference approach. The analysis showed that the switching costs have been lowered
considerably since number portability has been in force. However, a significant level of switching
costs still remains despite number portability. Finally, this paper provides some implications for the
competition strategy in the mobile communications market.
