This paper analyses quality discrimination when the monopolist provides two types of qualities for two-types of users, for example, in the software market. The users using software are confronted with two types of quality in using the software: one is related to learning, while the other is operation. In addition, the users are discriminated by the frequency of utilization for software, for example, low-demand and high-demand users. In this paper, the characteristics for bi-directional quality distortion in both learning quality and operation quality are analysed. It is shown that the distortion can occur both for low demanders and for high demanders. Finally, from public policy, a subsidy mechanism is introduced. 相似文献

Perceptions of risks from two groups of industrial radiographers, one from Hungary, (n = 45) and from the United Kingdom, (n = 29) were compared by the psychometric method. The comparison was made because both groups were at risk for high doses of ionizing radiation. We found the groups had similar demographic profiles but poor socio-economic conditions of Hungarians were associated with higher levels of emotional distress. Correlation HU-UK for personal and general risks were at a significant level for topics that included lifestyle and radiation risks. Perceptions of risks from radiation were small except for large personal risk from East European nuclear power plants. Knowledge of radiation risk intranationally was correlated positively with personal risk for UK radiographers and negatively for Hungarians. However, average overall risk perceptions from the same topic list for all radiographers did not differ significantly from a group (n = 1461) of UK citizens, though radiographer's risks from radiation were considerably greater. As a new lifesaving intervention it was proposed that radiation risk reduction could be achieved by genetic testing. 相似文献

Online social networking services (SNS) have been regarded as one of the most powerful online communication channels to propagate information to other users. It means that the online social networking services are providing users with efficient features (e.g., searching, managing and visualizing new information). It is important for many online collaborative applications to understand how the information can be propagated via such social media. Thus, we want to focus on a social tagging system (e.g., Flickr) where users can easily exchange resources as well as their tags. In this paper, given a certain tag, a social pulse can be established by counting (i) the number of users and (ii) the number of resources over time. More importantly, we assume that information can be propagated by (iii) inducibility from other tags by comparing social pulses. To conduct experimentation, a tag-based searching system (called Tagoole) has been implemented to collect a dataset from Flickr. 相似文献

In recent years, many industrial firms have been able to use roadmapping as an effective process methodology for projecting future technology and for coordinating technology planning and strategy. Firms potentially realize a number of benefits in deploying technology roadmapping (TRM) processes. Roadmaps provide information identifying which new technologies will meet firms' future product demands, allowing companies to leverage R&D investments through choosing appropriately out of a range of alternative technologies. Moreover, the roadmapping process serves an important communication tool helping to bring about consensus among roadmap developers, as well as between participants brought in during the development process, who may communicate their understanding of shared corporate goals through the roadmap. However, there are few conceptual accounts or case studies have made the argument that roadmapping processes may be used effectively as communication tools. This paper, therefore, seeks to elaborate a theoretical foundation for identifying the factors that must be considered in setting up a roadmap and for analyzing the effect of these factors on technology roadmap credibility as perceived by its users. Based on the survey results of 120 different R&D units, this empirical study found that firms need to explore further how they can enable frequent interactions between the TRM development team and TRM participants. A high level of interaction will improve the credibility of a TRM, with communication channels selected by the organization also positively affecting TRM credibility. 相似文献

The need for the management accounting system (MAS) to support marketing decisions has been identified in literature and practice. Accordingly, several improvements have been suggested with the main intention of providing more detailed information on marketing segments. Yet, even with respect to these improved systems it has to be acknowledged that the quality of the information provided will not be identical for all marketing segments: it can be assumed that it will be more precise for existing segments, which are already served by the firm, than for new ones, with which the firm has comparatively little experience. Further, it has to be considered that the MAS will seldom be the only source of useful information, as the example of the good salesforce having gained a ‘deep understanding’ of the market while doing his job shows. A problem arises if the acquisition of this additional information is (personally) costly and unobservable and therefore has to be motivated by incentive compensation schemes. This paper emphasizes that standard compensation contracts, as recommended by literature and practice, may fail to induce goal-congruent behaviour. It is shown that ranking commission rates according to the profitabilities reported by the MAS may be dysfunctional and that a non-intuitive rank order may be necessary to motivate the salesforce to become better informed and to use this knowledge appropriately. 相似文献

In expanding their market to the global level with clear and consistent global brand images across nations, marketers are ever confronting the issue of how to deal with different cultural values. Cultural value is identified as an influential factor on brand image and is widely accepted as one of the crucial concepts in understanding consumer consumption value, which determines choices of consuming everyday products and services. Most firms endeavoring to establish and maintain consistent global brand images, however, adopt a standardized brand image strategy that usually does not consider individual target markets” characteristics, including the concepts of cultural value and consumption value. This study developed a conceptual framework which incorporated cultural value not only as a direct antecedent of brand image, but also as an indirect antecedent of brand image through consumption value, and empirically tested it using the category of apparel. Following this framework, this study hypothesized the differences in brand image, cultural value, and consumption value between the U.S. and South Korea. Data were gathered through surveying university students residing in the San Francisco and Seoul metropolitan areas using a convenience sampling method. A total of 329 completed questionnaires were used in factor analysis, discriminant analysis, and structural equation modeling. The results provide insights into standardized brand image strategies and suggest some implementable tools that might prove effective in both countries. © 2009 Wiley Periodicals, Inc. 相似文献

Brand personality (BP) in the postmodern marketplace encompasses a variety of anthropomorphized attributes associated with a brand, reflecting on a wide spectrum of social, cultural, and psychological associations capturing various aspects in everyday life stories of consumers. Most prior research onBP, however, has employed a psychology‐based approach, and has not yet fully demonstrated the concept's market‐driven scope in the contemporary brand schema. To bridge the gap between the practitioner and scholar, this study employed a consumption symbolism approach to develop a multicomponent structure ofBP. A qualitative study was conducted with 36 brands of six product/service categories (fashion/luxury, beverage, automotive, personal computer, cosmetics, and retailer) within a specific context (South Korea). The results yielded a prototype of multicomponent BP structure consisting of one psychological component (traits) and three sociocultural components (narratives of socioeconomic/life scene/physical variability). The findings of the study broaden the current understanding of BP by suggesting a multidisciplinary perspective embracing its sociocultural aspects, and by empirically demonstrating the prototype reflecting on a wide spectrum of consumer narratives. 相似文献

We develop a framework to assess the statistical significance of expected default frequency calculated by credit risk models. This framework is then used to analyse the quality of two commercially available models that have become popular among practitioners: KMV Credit Monitor and RiskCalc from Moody's.
Using a unique database of expected default probability from both vendors, we study both the consistency of the prediction and its timeliness. We introduce the concept of cumulative accuracy profile (CAP) that allows to see in one curve the percentage of defaulting companies captured by the models one year in advance. We also use the Miller's information test to see if the models add information to the S&P rating.
The result of the analysis indicates that these models indeed add relevant information not accounted for by rating alone. Moreover, with respect to rating agencies, the models predict defaults more than ten months in advance on average.

Understanding the Benefit Sought by Rural Tourists and Accommodation Preferences: A South Korea Case
Duk‐Byeong Park Hee‐Jung Lee Yoo‐Shik Yoon 《International Journal of Tourism Research》2014,16(3):291-302
Rural tourism has been widely acknowledged for its effectiveness in contributing to rural areas’ development. With strong government support, rural tourism has developed in many countries during the last several decades. This study aims to improve the understanding regarding tourism in Korean rural areas using a segmentation approach. The responses of 442 tourists in 23 rural villages were analyzed. Four segments of tourists were identified based on the different benefits they sought for their vacation in rural establishments. The estimation of a multinomial logit model determined the socio‐demographic characteristics and the preferred accommodations of a rural tourist. Discussions and implications of the detailed findings are provided in the last section. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献
