This dissertation extends our understanding of how rivalries are formed, what their antecedents are, and how and why they influence consumer choices. Furthermore, the psychological processes underlying the rivalry effects and the moderating effects of temporal focus are uncovered.

As new information technology (NIT) has become a critical instrument for an organization to gain its competitive edge, the issue of how best to exploit and adopt NIT is now a pressing challenge for organizations and researchers alike. Based on upper echelon theory and individual differences literatures, this research paper endeavors to address the issue concerning the knowledge gap present in previous literature: the correlation between a top manager¡¦s personal traits and his NIT championing behavior. To bridge this gap, this paper attempts to explore to what extent a top manager¡¦s personality, ability, and belief characteristics can affect NIT championing behavior. We venture to propose in this paper a comprehensive model in which top managers¡¦ individual characteristics are integrated to facilitate the analysis of NIT adoption in organization. To test research model, Partial Least Squares (PLS) is used to verify the feasibility of the model proposed. Survey results from 130 top managers in Taiwan strongly support our proposition that a top manager¡¦s personality, ability, and belief have significant influence on NIT championing behavior. At the conclusion section of this paper academic and practical implication is discussed.

Many telecommunication companies are making considerable investments to take advantage of the new business possibilities offered by 3G mobile services. Previous research on mobile network, suggests potential consumers may not adopt these 3G services provided by telecommunication companies. Given that not all new mobile telecommunication technologies are accepted by the mass market in Taiwan. Thus, there is a need for research to identify the factors that affect consumer intention to subscribe third-generation (3G) mobile services. Based on the theoretical framework of Purchase Intention Model (PIM), network effects, perceived enjoyment and optimum stimulation level, an empirical study of the mass adoption of 3G mobile services in Taiwan was conducted. Data collected from 322 users in Taiwan confirmed our hypotheses and tested against the research model. The results support the proposed model in predicting consumer intention to subscribe 3G service. This study demonstrated that perceived over performance, relative advantage, network effects, perceived enjoyment and optimum stimulation level were key factors that resulted in individuals¡¦ subscription of 3G services. Lastly, several implications for innovation technology acceptance research and 3G service management practices are discussed.
