In this paper we use world cycling records to study the pattern of technological development of the track bicycle. We find that there is a strong evidence of ‘contagious’ effects among cycling records which in turn provides indirect evidence of ‘contagious’ effects among technological innovations. Interestingly, the ‘contagiousness’ of records is not a salient characteristic of track and field competitions where, arguably, technology plays a smaller role.  相似文献

The bulk of information and communication technology is made of weightless, implementable, and infinitely reproducible knowledge products (such as software and databases). These products are transferred by telephone lines, accessed through internet hosts, and processed through personal computers. In this work, the coefficient of the labour augmenting factor in the aggregate production function has been estimated using proxies of variables crucially affecting the diffusion of (non-rival and almost non-excludable) knowledge products. This specification provides interesting answers to some of the open issues in the existing growth literature. The most recent information, though available for a limited period, shows that telephone lines, personal computers, mobile phones, and internet hosts significantly affect levels and growth of income per worker across countries. The result is robust to changes in sample composition, econometric specification, and estimation approach.  相似文献

This article explores the relationships between several forecasts for the volatility built from multi-scale linear ARCH processes, and linear market models for the forward variance. This shows that the structures of the forecast equations are identical, but with different dependencies on the forecast horizon. The process equations for the forward variance are induced by the process equations for an ARCH model, but postulated in a market model. In the ARCH case, they are different from the usual diffusive type. The conceptual differences between both approaches and their implication for volatility forecasts are analysed. The volatility forecast is compared with the realized volatility (the volatility that will occur between date t and t + ΔT), and the implied volatility (corresponding to an at-the-money option with expiry at t + ΔT). For the ARCH forecasts, the parameters are set a priori. An empirical analysis across multiple time horizons ΔT shows that a forecast provided by an I-GARCH(1) process (one time scale) does not capture correctly the dynamics of the realized volatility. An I-GARCH(2) process (two time scales, similar to GARCH(1,1)) is better, while a long-memory LM-ARCH process (multiple time scales) replicates correctly the dynamics of the implied and realized volatilities and delivers consistently good forecasts for the realized volatility.  相似文献

Companies often develop collaborative joint ventures with nonprofits, and sometimes help their nonprofit partners with the marketing activities associated with these projects. Often, the assistance furnished is embodied in a transfer of knowledge from a firm to a nonprofit and involves knowledge about marketing techniques, strategies and methods. This article presents the results of a survey concerning the extents, natures and effectiveness of marketing knowledge transfers taking place between 291 UK enterprises and their nonprofit partner organisations. The survey covered the knowledge transfer methods that companies employed, the scope of the knowledge communicated, the factors that encouraged or impeded marketing knowledge transfer, and the considerations that determined which partner completed most of the marketing tasks associated with a project. It emerged that knowledge transfers occurred mainly through face‐to‐face communications, though with little formal teamworking. Both the extent and the effectiveness of transfers depended on the degree of marketing knowledge within the nonprofit partner, on levels of knowledge specificity and project complexity, and on the financial importance of the collaboration. The extent of knowledge transfer was additionally influenced by cultural and organisational distance. Similar considerations affected commercial partners' decisions to do most of the marketing work required by a collaboration. Such decisions were especially likely if anti‐marketing bias existed within the nonprofit organisation and if the nonprofit's staff knew little about marketing.  相似文献

Abstract

In some product categories, older consumers (aged 65+) tend to be more brand loyal, have smaller consideration sets and defer purchase more than younger consumers. This conservative behaviour may arise, in part, because older people are more socially isolated and thus receive less social influence relating to product options. In this multi-study research, the volume of word of mouth (WOM) is used as an indicator of social influence. The WOM received by men and women falls substantially beyond age 65, indicating that a deficit in advice may be part of the explanation for conservative decision-making. To test this proposition, the duration of customer tenure of the current brand (how long the respondent has been a customer) is used as a measure of purchase deferral and, as predicted, tenure is longer when less WOM is received. This evidence indicates that some older consumers experience a degree of social isolation, which affects their decision-making. In marketing and social policy, there is a need to promote procedures, technologies and institutions that help older people to connect with others.  相似文献

The term collaboration has been used throughout a variety of research disciplines to describe multiple types of interaction; yet, a unified, comprehensive definition of the construct remains elusive. This lack of clarity regarding the distinctions and commonalities between collaboration and other interaction concepts has resulted in conceptual confusion that affects practice and research in human resource management. Practitioners see collaboration as more of a buzzword than as an effective human resource strategy. Previous theory development efforts have not yet taken a comprehensive multidisciplinary approach. This has resulted in failure to integrate key themes across disciplines into an overall view of collaboration, which is a commonplace practice in business and military sectors alike. This paper describes a multidisciplinary conceptualization of collaboration and discusses the implications of this integrative theory to human resource management and strategy development as well as future research efforts.  相似文献

The purpose of this research is to build a conceptual foundation that examines network effects on the diffusion of environmental business practices (EBP) among suppliers. This research extends a network perspective to adoption of an environmental business practice across a large network of suppliers. The context of EBP is used to better understand adoption of a complex business practice, with perceived costs that are often greater than the perceived benefit. Variation in the level of structural and relationship embeddedness affect network diffusion of environmental business practices differently. Increased levels of structural and relational embeddedness are proposed to be positively associated with diffusion of EBP. From a practical standpoint, firms that leverage embeddedness may facilitate higher diffusion and adoption of environmental business practices. This facilitation may lead network actors to engage in EBP, and leverage benefits that may stem from these practices. This research introduces the concept of embeddedness to the environmental supply chain literature. Practicing managers can use the findings in this research to better position themselves within a network to diffuse EBP. This research also helps managers understand how supply chain members that are weakly connected to the primary network are important for introducing new ideas and innovations.  相似文献

This research focuses on the strategic alignment of a firm's human resources. Specifically, I investigate employee ‘line of sight’ to an organization's strategic objectives. Line of sight is conceptualized as an employee's understanding of an organization's objectives and how to contribute to those objectives. Line of sight was expected to vary across individual characteristics (e.g. hierarchical level, tenure) and relate to important work outcomes (e.g. work attitudes, turnover). Results of a field study confirmed many of the hypotheses, supporting the importance of this construct to research and practice.  相似文献

Do Traditional Chinese Cultural Values Nourish a Market for Pirated CDs?   总被引:2,自引:0,他引:2  
On one hand, Chinese consumers are well known for conspicuous consumption and the adoption of luxury products and named brands. On the other hand, they also have a bad reputation for buying counterfeit products. Their simultaneous preferences for two contrasting types of product present a paradox that has not been addressed in the literature. This study attempts to present an explanation of this paradox by examining the effects of traditional Chinese cultural values and consumer values on consumers’ deontological judgment of pirated CDs and the amount of social benefits they perceive they gain from them. We interviewed 300 Hong Kong Chinese consumers, and found that face consciousness increased materialism and risk aversion, thereby producing a favorable deontological judgment of pirated CDs. Face consciousness also has a direct effect on the amount of social benefits perceived in pirated CDs. Both favorable deontological judgment and perceived social benefits contributed to a strong intention to buy pirated CDs. The results are discussed in a cultural perspective.  相似文献
