When a firm launches a market-creating innovation, it launches a new product for which there are no close product substitutes. Thus, the new product causes a shift in the existing product-market structure of an industry. This paper reports on the findings of the analysis of 51 large pharmaceutical firms and their market-creating activities. The study suggests that market-creating firms have capabilities in both R&D and marketing. Furthermore, market-creating firms enjoy stronger efficiencies, manage costs better and make more profitable use of their assets.  相似文献

The objective was to determine patterns and circumstances of childhood falls in a low-income setting in Dar es Salaam, Tanzania. This cross sectional study is based on a household survey conducted in July 2009. A total of 3927 children up to age 18 from 1928 households in 15 sampled wards were surveyed through a structured questionnaire. The current study includes information regarding fall occurrence, socio-demographic and economic factors. Data were analysed using chi-square, t-test and logistic regression. Male children had 42% higher odds of falls compared to females, and rural residents had more than two times higher odds compared to urban residents. Falls occurred three times more among age group 1-4 and two times more among age group 5-9 compared to those between 15 and 18 years. Most falls occurred outdoors (62%) while playing (51%) with boys being over-represented. Females and children aged 1-4 years fell more from stairs whereas most infants fell from furniture. Male gender, younger age groups and rural residence were significant factors for fall injuries. The circumstances in which these falls occur also differ significantly. Intervention efforts should emphasise these patterns.  相似文献

The purpose of this article is to determine market orientation’s relative impact on small-business performance, compared to other influences, in an integrated model using longitudinal data. Contrary to expectations based on the management literature, the results indicate weak causal relationships between market environment, small-firm structure, and small-firm strategy. The results further indicate weak influences of these variables, but strong and consistent influences of market orientation, on various measures of small-firm performance. Contrary to expectations based on business policy literature, relative product quality and new product success were not significant influences on profitability, perhaps due to the significant influence of market orientation on these variables. In addition, although increases in growth/share had a significant short-term influence on increases in profitability, high levels of previous years’ firm growth/share had a negative influence on current profitability. The previous year’s level of firm coordinating systems and market competitive intensity has a significant impact on the level of small-firm market orientation.  相似文献

In 2015, the Federal Communications Commission (FCC) imposed common carriage regulation—so-called Title II requirements—on previously unregulated broadband Internet service providers. The regime shift was premised on the FCC’s findings that such rules had demonstrably yielded economic gains. This paper evaluates the FCC’s empirical arguments and finds them uncompelling. Adjustments for inflation or general economic trends eliminate the effects cited by the FCC. Moreover, contrary to the Commission’s assessment, mobile services and broadband markets have shown notable growth in response to deregulatory events that reduce Title II requirements.  相似文献

The authors review Peter Drucker’s contributions to marketing theory and practice. A bibliometric analysis of Drucker’s academic influence in marketing is presented. The five main tenets that are derived from the bibliometric study are expanded upon as follows: (1) The Marketing Concept: Creating Value for Customers; (2) Broadened Role of Marketing in Society: Corporate Social Responsibility, Consumerism, Social Marketing, and Lessons from Non-Profit Organizations; (3) Contributions to Marketing Strategy: The Obvious and Not So Obvious; (4) Marketing-Innovation Interface: New Product Development; (5) Future of Globalization: Rise of Non-National Enterprises.

Unlike other aspects of the American health experience, there is a current void of information on expensive illness experiences. This paper is designed to fill this void and prrsents an analysis of the incidence and cost of catastrophic illness in the United States. Catastrophic illness is defined as an illness episode for which a person incurs $5,000 or more of medical expenses in a calendar year. This information is used to provide a framework for focusing the debate about catastrophic and national health insurance.  相似文献

Corporate bankruptcy prediction has attracted significant research attention from business academics, regulators and financial economists over the past five decades. However, much of this literature has relied on quite simplistic classifiers such as logistic regression and linear discriminant analysis (LDA). Based on a large sample of US corporate bankruptcies, we examine the predictive performance of 16 classifiers, ranging from the most restrictive classifiers (such as logit, probit and linear discriminant analysis) to more advanced techniques such as neural networks, support vector machines (SVMs) and “new age” statistical learning models including generalised boosting, AdaBoost and random forests. Consistent with the findings of Jones et al. ( 2015 ), we show that quite simple classifiers such as logit and LDA perform reasonably well in bankruptcy prediction. However, we recommend the use of “new age” classifiers in corporate bankruptcy modelling because: (1) they predict significantly better than all other classifiers on both the cross‐sectional and longitudinal test samples; (2) the models may have considerable practical appeal because they are relatively easy to estimate and implement (for instance, they require minimal researcher intervention for data preparation, variable selection and model architecture specification); and (3) while the underlying model structures can be very complex, we demonstrate that “new age” classifiers have a reasonably good level of interpretability through such metrics as relative variable importances (RVIs).  相似文献
