The ability to forecast market share remains a challenge for many managers especially in dynamic markets, such as the telecommunications sector. In order to accommodate the unique dynamic characteristics of the telecommunications market, we use a multi-component model, called MSHARE. Our method involves a two-phase process. The first phase consists of three components: a projection method, a ring down survey methodology and a purchase intentions survey. The predictions from these components are combined to forecast category sales for the wireless subscribers market. In the second phase, market shares for the various brands are generated using the forecast of the number of subscribers that are obtained in Phase 1 and the share predictions from the ring down methodology. The proposed methodology produces the minimum Relative Absolute Error for each market as compared to the forecasts from each individual component in the first phase. The value of the proposed model is illustrated by its application to a real world scenario. The managerial implications of the proposed model are also discussed. 相似文献

春兰集团是中国较早走上多元化之路的大型企业集团,先后进军摩托车、卡车、高能动力镍氢电池、投资贸易等领域,形成了产品多元化经营的格局。春兰集团实施非相关多元化经营的战略路径是:以掌握产业核心技术为战略核心;以企业并购为战略重点;以整体绩效为战略目标。企业非相关多元化经营的风险甚大,必须采取相应措施予以规避:科学选择多元化经营的进入领域;确保企业的核心竞争力不受削弱;注意"协同效应";保持合理的负债水平;要注重规模经济的效应。 相似文献

Questions about universal service continue to evolve as information and communication technology advances, bringing new platforms, services, and business models. Concerns about exclusion remain, particularly in times of transition to new technologies and platforms. While the universal service literature is rich in econometric studies that indicate the drivers of household telephone penetration, without qualitative data directly from those households that experience phonelessness, we cannot understand the causes well enough to design effective policy. This research explores why people are phoneless in the current environment of increased platform and business model choices. Particular focus is placed on understanding the relationship between new technology, platforms and business models and phonelessness. Data is obtained from surveys completed by approximately 100 individuals in Massachusetts who are currently without any voice connection, either landline or mobile, or have been sometime in the past ten years. The survey includes questions about different platforms and communication services in order to learn how they have led to phonelessness. The results of the pilot study show that the vast majority of phoneless households do not choose to be phoneless. The study also shows that the most frequent causes of phonelessness in this population are unemployment and unpredictable bills. Many instances of unpredictable bills leading to phonelessness occur with wireless service or bundled services but are the result of business models for service provision rather than the platforms themselves. Prepaid wireless service is a market-based solution that helps households prevent phonelessness by reducing unpredictability. Universal service policy for voice and broadband can better reduce exclusion with greater attention to business models and practices versus technologies and platforms, and increased emphasis on prepaid service to reduce unpredictability. 相似文献

The wireless industry is one of the most capital intensive high-technology industries. This paper applies real options techniques to estimate investments under uncertainty in two new ventures: (a) deferral of the expansion from 2.5G to 3G networks; and (b) expansion of a 2.5G network using Wi-Fi as an alternative technology. The cases are examined and analyzed both qualitatively and quantitatively, using realistic assumptions and parameters. Investment cost, number of subscribers, pricing of services, and risk are at the core of investment decision processing. In both cases, sensitivity analysis of the value of the (real) option considering the above key parameters was conducted, to extrapolate useful findings that should be taken into consideration by the decision makers in wireless companies. 相似文献

We provide evidence on the influence of expectations and network effects on the timing of technological adoption. By considering
a sample of SMEs operating in Italy, we focus on the determinants of their decision to adopt Fast Ethernet, a communication
standard for Local Area Networks (LANs). We find that both expectations and network effects significantly affect the timing
of adoption. In particular, price expectations generally tend to delay adoption and (indirect) network effects in the form
of backward compatibility as well as informational spillovers tend to foster adoption. Firm size also matters.
