Smart devices also make user's role change and be powerful. In other words, user's power is stronger by smart devices in smart media industry and especially social environment like application market is catalyst for growth of user's role and power. On the other hand, it is hard for a firm to have all abilities and sources in this sudden change. Therefore, firms have to make their strategy considering user's role. For that reason, firms can use networks such as university, researcher, firm and user from the viewpoint of open innovation. I argue that users have some roles as one of the main agents in smart media industry affecting firm's strategy and performance. 2014-01-01T00:00:00Z https://hdl.handle.net/10419/106830 Title: Effects of transaction and switching costs on mobile market performance Authors: Basaure, Arturo; Suomi, Henna; Hämmäinen, Heikki Abstract: The exponential growth in demand of mobile Internet urges mobile network operators (MNOs) to increase the supply of wireless network capacity at a high pace. From this perspective, operators should not only obtain further network capacity but also make a more efficient use of the existing capacity. Latest developments in load balancing solutions address this challenge through two opposite evolution paths, cooperative and competitive. On the one hand, operator-driven cooperative solutions permit operators to trade spectrum capacity at wholesale level through e.g., Dynamic Spectrum Access (DSA) technologies. On the other hand, user-driven competitive solutions enable users to access and switch between different networks e.g., by adopting user multihoming capability and thereby intensifying retail competition. The deployment of these solutions determines the level of transaction and switching costs and consequently the level of retail competition and wholesale trading of spectrum capacity in a mobile market. This paper analyzes the effects of decreasing these costs in different mobile access scenarios, by employing agent-based modelling. Thus, the performed simulations aim to understand the effect of load balancing technologies on market performance. Finally, the paper suggests policy implications for different markets. 2014-01-01T00:00:00Z https://hdl.handle.net/10419/106887 Title: Understanding broadband under-utilization in Japan Authors: Bourna, Maria; Mitomo, Hitoshi Abstract: Improved internet connectivity has been a consistent aim of Japanese telecommunications policy in the past decades, however, despite the high availability of high speed and ultra-high speed broadband services, actual use has yet to match network capacity. This study hopes to explore this paradox by looking at the factors that affect demand for broadband services. To achieve this, the relationship between overall broadband adoption and two basic demand factors, namely price of internet services and presence of a competitor in the form of wireless broadband, was examined over a 12-year period. The findings suggest that the lag in adoption can be attributed to both a higher demand for wireless connectivity and high broadband contract prices, while network effects may play a positive role in diffusion. Given that Japanese broadband policy has tended to focus more on the role of price as a mechanism for improving penetration, this study ultimately contributes to the discussion of policy efficiency by providing some empirical basis for the consideration of alternative demand-side incentives. 2014-01-01T00:00:00Z
