In this paper, I estimate consumer preferences for IMT (International Mobile Telecommunications)-2000 service in Korea using the conjoint analysis technique. For statistical models, I estimate the random coefficient discrete choice model using the Bayesian approach with Gibbs sampling. The results show that there are large variations in consumer valuation(More)
Intensified technology convergence, increasing relatedness between technological fields, is a mega-trend in 21st century science and technology. However, scientometrics has been unsuccessful in identifying this techno-economic paradigm change. To address the limitations and validity problems of conventional measures of technology convergence, we introduce a(More)
In the rapidly growing, competitive information and communications technology market, demand forecasting for new technologies is difficult, yet important. Our study describes a forecasting methodology designed for newly introduced technology for which limited data is available that uses algebraic estimation, Bayesian updating, and conjoint analysis. In the(More)

In this paper, we develop prelaunch forecasting model reflecting competition structure among various technologies and this model overcomes limitations of the Bass-type diffusion model which relies upon historical sales data. This paper applies our model to the HomeNetworking(H-N) market where there exist various alternative technologies in South Korea.(More)
