An assessment of value creation in mobile service delivery and the moderating role of time consciousness 总被引:3,自引:0,他引:3
This study focuses on the perceived utilitarian value of a new service delivery mode, the mobile channel. The authors develop a framework that incorporates three mode-specific benefits - time convenience, user control, and service compatibility - as well as two costs - perceived risk and cognitive effort - as antecedents of perceived value. Because of the pervasiveness of time criticality as a value-added characteristic of the mobile channel, they also investigate the moderating influence of consumers’ time consciousness. They empirically investigate the model using mobile brokerage services as an illustrative application. The results reveal that the identified antecedents, with the exception of service compatibility, have a strong impact on mobile channel value perceptions, which in turn influence behavioral intentions. The authors also find that time consciousness moderates the aforementioned relationships. 相似文献

The number of channels that retailers can use interchangeably to provide customer service has increased. We report on a study of clients of a large retail bank that investigates the channel performance satisfaction-behavioral intentions relationship when the traditional service channel (i.e., branch office) is extended with technology-mediated channels (i.e., internet banking and telephone banking). For routine services, our findings suggest that behavioral intentions are most strongly influenced by satisfaction with office-related performance factors. For nonroutine services, satisfaction with service employee performance is the most significant driver of intentions. Our analysis also reveals interaction effects between traditional and technology-mediated channel performance satisfaction levels. These effects vary across service types, indicating contingencies in channel substitution and complementarity. 相似文献

Along the lines of Amihud and Mendelson (1987a, 1989,1991), this study investigates the unique trading mechanism of the Korea Stock Exchange (KSE) and its intraday behavior of stock price volatility. The evidence from this study indicates that the introduction of an additional clearing procedure at the afternoon closing makes price discovery process more efficient than before from the viewpoint of stock price volatility. Hence, such trading mechanisms can be applied to emerging stock markets as well as developed stock markets. In addition, based on intraday analysis, stock price volatilities appear to occur mainly during the trading period, not during the lunch break or overnight period. Consequently, the results confirm the previous studies that information arrival and trading activities are the main sources of volatility. 相似文献

Abstract: Using a sample of 129 mergers and acquisitions (M&As) in the US between publicly traded acquirers and targets in research and development (R&D) intensive industries over the period of 1994-2004 and a size- and industry-matched sample, we examine the relation among targets' R&D activities, the probability of acquirers' writing-off in-process R&D (IPRD), and acquirers' returns around the time of M&A announcements. We find that firms acquiring targets with higher R&D investments tend to write off some of the acquired R&D assets upon the completion of the M&As. We also find that the median cumulative abnormal return during the three days around M&A announcements for acquirers with subsequent IPRD write-offs is −2.73% while the return for acquirers without IPRD write-offs is −0.60%. This suggests that acquirers' stock returns around M&A announcements are much lower when investors expect acquirers to expense IPRD. The results are consistent with our conjecture that acquirers tend to write-off IPRD when they acquire overvalued targets. We also find that IPRD write-offs do not increase earnings or stock returns of acquirers after M&As, which is inconsistent with an earnings management hypothesis. 相似文献

The use of personal response systems (PRSs) to support the learning process is increasing. This study examines the impact of PRSs from individual learners’ and instructors’ perspectives on individual learners’ engagement with PRSs and their learning performance. Data were collected from a sample of 236 undergraduate bachelor of business administration students in the School of Business at a Hong Kong university. The results indicated that the learner interface was important to individual learners’ engagement with PRSs and their learning performance. Instructor attitude and technical competence had significant impacts on learning performance. Engagement with PRSs partially mediated the effect of both perspectives on learning performance. Implications for the theory and practice of individual learners’ learning performance are discussed. 相似文献

This research sheds new light on how information technology (IT) assimilation affects exploratory and exploitative innovation in the context of small‐ and medium‐sized firms (SMEs). This contextualization is important in establishing the boundary conditions for the theory, as well as generating specific managerial insights for SME managers. A sample of 248 U.K.‐based SMEs in the manufacturing industry demonstrates contextual ambidexterity (CA) mediates the relationship between IT assimilation and two types of innovation. This finding highlights that IT assimilation does not automatically promote innovation. Instead, IT assimilation represents a critical resource that enables the effective implementation of CA, which in turn affects innovation. This implies that SMEs cannot fully realize the potential of their IT assimilation and use it to enable innovation without implementing CA. Furthermore, this study differentiates between two different dimensions of knowledge base: knowledge breadth and knowledge depth. This study finds that knowledge breadth moderates the indirect IT assimilation–exploratory innovation relationship by influencing the effect of CA on exploratory innovation. Knowledge depth, on the other hand, moderates the indirect IT assimilation–exploitative innovation relationship by influencing the effect of CA on exploitative innovation. This finding implies that SMEs can benefit from their IT assimilation that enables them to engage in CA, which in turn allows them to perform innovation. However, it is apparent that the dimension of knowledge that SMEs hold internally can determine what types of innovation that they are able to perform. 相似文献

We examine institutional blockholders’ influence on income‐smoothing practices in the Korean market, which provides an interesting setting where family‐oriented chaebols dictate the corporate landscape and impede shareholder activism. The empirical results reveal that institutional shareholders with a short‐term (long‐term) investment horizon facilitate (constrain) managerial myopia. This positive (negative) association is most evident among firms with domestic institutional investors. Therefore, we argue that the presence of domestic institutional investors with transient investment goals incentivizes firms’ management to smooth out earnings. 相似文献

In the U.S., virtually no new coal-fired power plants have been built in recent years. Both industry experts and academics seem to believe that no rational firm will build a new coal-fired plant. Will such a trend continue in the future? To provide insights into this question, we investigate the optimal decision of an electricity company with an irreversible and deferrable opportunity to build either a new coal-fired or natural gas-fired power plant as its new base-load resource. According to our real option analysis, the optimal decision depends on the location. In the case of the eastern U.S., it is optimal to choose a natural gas plant if a firm is given a choice among a new natural gas plant, a new coal plant and deferring the investment. However, contrary to the common sentiment in the industry and academia, building a new coal plant in the western U.S. is still more economical than building a new natural gas plant in the absence of emission pricing. Furthermore, introducing carbon pricing to western U.S. states, as California did, can substantially increase the probability that a firm will optimally choose a natural gas plant over a coal plant. 相似文献

Worldwide medical facilities differ, and for this reason, the causes of death can vary. Cancer is considered the second leading cause of death after heart disease worldwide, and the same causes of death are observed in the United States (US). Therefore, the purposes of this study are to explore worldwide research levels in the field of cancer and the social collaboration of researchers and institutions in this field. This article examines the structural patterns of international co-authors and co-institutions in science citation index papers in cancer research. The study uses measures from the social network analysis method, including degree centrality, betweenness centrality, eigenvector centrality, and effectiveness, to investigate the effects of social networks in the area of cancer research. Empirical analysis results identify the US is the most central country, followed by Germany, Italy, France, and China, in terms of co-authored networks in this research field. Institutional analysis results indicate that the University of Milan is at the top in terms of degree centrality. The Gustave Roussy Cancer Campus in France and German University of Düsseldorf occupy the second and fourth positions, respectively. The University of California in Los Angeles and Harvard University, both in the US, are at third and fifth positions, respectively. 相似文献
