Digital video recorders (DVRs) are an emerging technology that is fundamentally changing the competitive landscape in industries that advertise on television. Perhaps the most familiar impact of DVR technology is that it enables consumers to avoid advertisements (ads) by fast forwarding through them. However, this “zipping” of ads is only one aspect of the impact of DVR technology. DVRs also collect a wealth of information at the consumer level that can be used by firms to target their ads more effectively. We examine how this targeting capability moderates the impact of ad avoidance in a competitive setting. Insights are provided on how best to manage this emerging technology in terms of the key managerial decisions of product pricing and advertising efforts, as well as its impact on profits in a competitive (duopoly) marketplace. 相似文献

The fast-changing scenario related to the COVID-19 pandemic calls for firms to rapidly redefine and innovate their strategies to sustain their businesses, with research emphasizing the key roles of digital technologies and servitization. We aim to enrich the theoretical debate on this matter by assessing how small and medium-sized enterprises (SMEs) achieve product innovation under time constraints by leveraging two specific technology groups (information and communication technologies [ICT] and Industry 4.0 data-processing technologies) and servitization. The research is based on a mixed-method approach consisting of an original survey completed by 257 Italian SMEs (grounded on a previous qualitative study about such SMEs' behaviors during the first Italian lockdown), followed by in-depth interviews with the owners and/or managers of the eight SMEs that participated in the survey. The results show a positive relationship between the increased use of digital technologies (ICT and Industry 4.0 data-processing technologies) during the pandemic with servitization and, in turn, with product innovation. Specifically, the increased use of ICT during the pandemic had a direct positive effect on product innovation, while Industry 4.0 data-processing technologies affected product innovation only through the full mediation of servitization. The qualitative study allowed us to highlight how the different kinds of digital technologies supported SMEs’ innovation (servitization and product innovation) during the pandemic. The theoretical and practical contributions of this study are discussed. 相似文献

中间品进口作为国际技术溢出的主要途径,对促进一国生产及出口结构升级有着非常重要的影响。本文利用2000-2011年中国工业企业数据库和海关贸易统计数据库的合并数据,基于进口产品种类变化的利得视角,考察了中间品进口种类扩张对企业出口复杂度提升的影响效应。研究显示:企业从国外进口更多种类的中间品有助于促进其出口复杂度的提升,该结论在经过内生性处理、更换核心指标测度方法等多种检验后,具有较好的稳健性;从影响机理上看,中间品进口种类扩张主要通过“产品创新”的直接途径和“生产率提升”的间接途径来推动企业出口复杂度的提升;此外,受进口来源国类别、企业所有制形式以及行业技术特征等异质性因素的影响,中间品进口种类扩张对出口复杂度提升的影响程度存在不同。本文从经验上证明了“以进口强出口”发展模式的合理性,对评估我国当前正在实施的“扩大进口”政策的经济效益,以及推动“贸易强国”建设有着重要意义。 相似文献

One of the greatest challenges related to the use of piecewise exponential models (PEMs) is to find an adequate grid of time-points needed in its construction. In general, the number of intervals in such a grid and the position of their endpoints are ad-hoc choices. We extend previous works by introducing a full Bayesian approach for the piecewise exponential model in which the grid of time-points (and, consequently, the endpoints and the number of intervals) is random. We estimate the failure rates using the proposed procedure and compare the results with the non-parametric piecewise exponential estimates. Estimates for the survival function using the most probable partition are compared with the Kaplan-Meier estimators (KMEs). A sensitivity analysis for the proposed model is provided considering different prior specifications for the failure rates and for the grid. We also evaluate the effect of different percentage of censoring observations in the estimates. An application to a real data set is also provided. We notice that the posteriors are strongly influenced by prior specifications, mainly for the failure rates parameters. Thus, the priors must be fairly built, say, really disclosing the expert prior opinion. 相似文献

In industrial purchasing contexts firms often procure a set of products from the same suppliers to benefit from economies of scale and scope. These products are often at different stages of their respective product life cycles (PLCs). Firms consider multiple criteria in purchasing such products, and the relative importance of these criteria varies depending on the PLC stage of a given product. Therefore, a firm should select suppliers and choose sourcing arrangements such that product requirements across multiple criteria are satisfied over time. The extant models in sourcing literature for evaluating and selecting suppliers for a portfolio of products have not considered this important and practical issue faced by firms. This article proposes a mathematical model that effectively addresses this issue and contributes to the sourcing literature by demonstrating an approach for optimally selecting suppliers and supplier bids given the relative importance of multiple criteria across multiple products over their PLC. The application of the model on a hypothetical data set illustrates the strategic and tactical significance of such considerations. 相似文献

Language ideologies and the consequences of standardization 总被引:1,自引:0,他引:1
James Milroy 《Journal of Sociolinguistics》2001,5(4):530-555
This paper explores the effects of the standard language ideology on attitudes to language of nonlinguists and of language specialists, and considers how far linguists themselves have been affected by – and have contributed to – this ideology. The primary definition of standardization is taken to be the imposition of uniformity upon a class of objects . Attitudes to language within standard language cultures are then reviewed and contrasted with unstandardized situations, in which the boundaries of languages are indeterminate. It is therefore suggested that determinate languages, such as English, may be defined more by ideologies than by their internal structures. Some effects of standardization on the work of linguists are then reviewed. This is followed by a discussion of the importance of the process of legitimization in contributing to the standard language culture, and of the contribution of language specialists themselves to this process. Finally, certain matters arising are reviewed. 相似文献

There exists a joint-cost allocation problem in the public sector, particularly highlighted by the cost-based national pricing of blood products in England, supposedly derived using volume-driven activity-based costing (ABC): an approach criticised by the implementation criteria propounded for ABC within the academic literature. In contrast, we believe that the contributions of quality-associated operations-based drivers, described within ABC, together with the net realisable value method, usually recommended as the optimal joint-cost allocation method, provide the beginnings of a solution. This paper sets out a methodological development from this platform that links allocation decisions with the issue of value. The bipolar nature of the model is based upon the combination of two types of allocation. One allocates joint costs according to the altered value of source material when competing non-joint alternative products exist. The other allocates joint costs according to product outcome values ascertained separately for the physical specification elements that comprise each of the range of joint products. The overall emphases are on academic context, model generalisation, the facilitation of cost-effective choices between joint products and non-joint alternatives, and possible future trends in the application of the method. 相似文献
