An analysis of demand for new devices in the transition from terrestrial broadcasting to digital
the case of digital televisions in Japan

"In this paper we first analyze the direct consumer benefits of broadcast digitization from a political viewpoint. More precisely, we select a current model digital television with high resolution and large screen, and estimate consumer utility by the stated preference (SP) method. Through this analysis, we obtain data for forecasting the future diffusion of digital television. Furthermode, from a more economic viewpoint, we analyze complementary between hardware (digital television) and software or content (the number of available channels or commencing date of digital broadcasting), and obtain empirical evidence of an indirect network externality in the Japanese broadcasting market. Our paper has five sections. In Section 2, we survey related previous studies and describe the design and basic statistics of our questionnaire. In Section 3, we explain the conjoint analysis estimation model, then we interpret the estimation results in Section 4. Finally, in Section 5, we summarize our results and consider the implications for the future." [Information des Anbieters]
