Discrete Choice Analysis of Demand for Broadband in Japan

The remarkable development of Japan’s broadband (BB) market has attracted attention worldwide. This paper is one of the first to analyze Japan’s BB demand (including FTTH) using a discrete choice model. Our main conclusions are first, there is a distinction between narrowband (NB) and BB services based on a nested choice structure. Second, considering own-price elasticities of access demand, ADSL is inelastic, but FTTH and CATV are elastic. Third, in ADSL submarkets, low-speed and high-speed ADSL are becoming more elastic.
