In this study we propose a mathematical definition of the consumption efficiency of multi-attribute products in the price–quality space. A new model, the discrete Range Adjusted Measure (RAM) model, is suggested as an empirical tool to measure the level of consumption efficiency. We further discuss the effect of consumption efficiency on the innovation incentive. Empirical work is made for the mobile phone market. We expect that the consumption efficiency concept will contribute to the extension of the traditional framework of production efficiency analysis on the one hand and to the understanding of the nature of innovation in a technology-intensive market on the other hand.JEL Classification: C67, D11, D12, D21 相似文献

Our planet is gradually moving towards an urbanized world. Modern urban agglomerations tend to turn nowadays into advanced information hubs supporting a smart management of dynamic urban systems. The currently popular notion of ‘smart cities’ aims to provide a new perspective for sustainable and high-performance strategies of city stakeholders in our ‘urban century’. In this context, digital information technology provides a new tool for efficient and effective management and planning of urban space, inter alia in the field of transportation, environment, public facilities or advanced service provision to citizens. This paper aims to offer, first, a concise overview of the emerging opportunities of information and communication technology (ICT) for smart urban policy; digital technology in particular, appears to provide novel pathways for modern planning strategies in smart cities. Against this background, the paper sketches out the complex force field of global urbanisation phenomena and highlights the data and information needs for strategic planning of cities (using inter alia as a framework the so-called ‘urban piazza’ strategy framework). Secondly, various new decision support tools that are currently emerging and that offer a new promising scope for handling complex urban management issues (for instance, on accessibility, congestion, safety or sustainability) are briefly presented. And finally, the potential of such digital data systems for urban management and policy is concisely illustrated by means of some recent applications in the area of smartphone data systems. The paper concludes with a discussion of the challenges ahead for urban policy, inter alia by paying attention to institutional and governance aspects of ‘big digital data’ management in urban systems. 相似文献

The framework offered in this study provides empirical evidence concerning the interaction between distributive, procedural and interactional perceived justice and loyalty program satisfaction on relational satisfaction in the mobile telecommunication context. Firms that rely on justice perception for strategy implementation are able to attain customer retention. This study suggests a theoretical model of customer retention that aims at investigating the role of satisfaction with loyalty program on relationship marketing. The structural equation modeling was used to test the hypothetical relationships. A self-administrated questionnaire was distributed to a total of a convenience sample of 520 customers of multiple mobile phone companies. The target population includes customers who have subscribed to a loyalty program. Results show that distributive justice moderates the relationship between satisfaction with the loyalty program and relational satisfaction. The results highlight the need to focus on distributive justice in order to nurture satisfaction and loyalty. Satisfaction with the loyalty program is a key predictor of a satisfactory relationship with the operator and customer retention. 相似文献
