The diffusion of mobile telecommunications services in Korea

This study investigates the diffusion of mobile telecommunications in Korea. The aim is to compare the performance of logistic model of diffusion with that of a time series autoregressive moving average model and to identify factors that determine the diffusion adoption process. Empirical results are based on annual data on cellular mobile subscribers covering 1984 to 2002. Results suggest that, the diffusion speed increases with per capita GDP, but it decreases with the number of main telephone lines in operation.
