Research on big data has highlighted that a crucial element to create value from data is the capability of aligning different stakeholders’ interests. However, it has not yet been investigated empirically how this process of alignment can be realized. We conduct a multiple case study on the two leading platforms involved in the online dissemination of cultural heritage – Europeana and Google Arts & Culture. Our findings reveal that a platform overtakes a rival one when it turns on multiple drivers of value creation in such a way that the drivers contribute to realigning the interests expressed by the stakeholders whose strategic objectives and beliefs were formerly divergent – or simply unrelated – to each other. This capability of realigning different stakeholders’ interests is independent of the level of industry-specific knowledge that the platform orchestrator has. The dynamics we document imply that Google has assumed a system integration role in the cultural ecosystem. This generates new trade-offs for museums in the way they generate value for the tourism industry. The paper enriches our understanding of what strategies digital platforms adopt to create value in big data contexts and provides a base to continue the investigation on other ecosystems driven by big data.  相似文献

Postponement is a well-known organizational concept and usually relates to the deferment in time of manufacturing and/or logistics operations. In the current global competitive landscape, situations where postponement can be applied are rapidly increasing. Faced with the wide range of customs duties and free-trade agreements currently in place, companies need to (re)design their postponement strategies to customize their products appropriately, and to the proper degree, in each market. As the actual location where operations take place has a major impact on a company’s overall performance, the spatial perspective must also be taken into account when designing global postponement strategies, alongside the conventional temporal perspective. Heretofore, the academic literature does not offer any comprehensive framework on a global scale either for handling what is known as the postponement boundary problem, or for conceptualizing the related postponement strategies. Building on previous research, the aim of the present study was to investigate the postponement concept in a global environment with a downstream focus. The intended purpose is twofold: first, to review and expand previous studies on the subject and, second, to provide some guidelines for conceptualizing global postponement strategies. A structured literature review was first conducted, followed by the development of a framework that combines both the temporal and the spatial dimensions. Finally, the framework was applied to a group of 28 business cases taken from the literature, to act as a bridge between academic theories and practitioners’ current business operations.  相似文献

We study the dynamic impact of recycling through its effect on the production set of the economy and its relationship with natural resources. The contribution of renewable and recyclable resources for sustainability is studied. Although in the short run recycling may alleviate resource scarcity, in the long run it is not enough to compensate for the exhaustibility of non-renewable resources and the possibility of obtaining non-decreasing output paths crucially depends on the extent to which production rests on renewable resources. Furthermore, recycling interacts with natural resource growth, surprisingly not always favoring sustainability. The Production and Recycling Function is a generalization of the traditional production function, providing an integrated view of regular production and recycling and representing the production set of the economy when a recycling technology is available.  相似文献

A kernel-based method for nonparametric estimation of variograms   总被引:2,自引:0,他引:2  
Variogram estimation plays an important role in many areas of spatial statistics. Potential areas of application include biology, ecology, economics and meteorology. However, it is common that, for example under highly correlated patterns, traditional estimators can not reflect all the spatial features or dependencies. In this paper, we present an alternative distribution-free estimator based on nearest-neighbour estimation with a non-constant smoothing field that is better able to adapt to spatially varying features of the data pattern. We present a simulation study to compare our new estimator to a nearest-neighbour estimator built with a constant smoothing parameter and to the classical variogram estimator. We apply our method to analyze two ecological data sets.  相似文献

Exploring different views of exchange rate regime choice   总被引:1,自引:0,他引:1  
The empirical distinction between de facto and de jure exchange rate regimes raises a number of interesting questions. Which factors may induce a de facto peg? Why do countries enforce a peg but do not announce it? Why do countries “break their promises”? We show that a stable socio-political environment and an efficient political decision-making process are a necessary prerequisite for choosing a peg and sticking to it, challenging the view that sees the exchange rate as a commitment device. Policymakers seem rather concerned with regime sustainability in the face of adverse economic and socio-political fundamentals.  相似文献

The paper studies the motivations behind banks’ shareholding of non-financial firms using a panel of large Italian companies in the period 1994–2000. Empirical evidence shows that banks are shareholders of companies that are less profitable, have experienced slower growth, are more indebted, are endowed with collateral and have hard time to repay their debt out of current income. Banks are more likely to hold shares in companies they lend to. Overall the evidence suggests that there is complementarity between bank equity holding and lending. A plausible explanation is the shareholder–debtholder conflict, the evidence is weakly compatible with governance and information hypotheses.  相似文献

This paper highlights issues in the theory of voluntary provision of public goods, building on the investigation by Peacock in connection with the contributions by Coase and Buchanan. Our goal is twofold. We first draw attention to the early literature investigating the provision of public goods and to the successive theoretical analysis. We then focus on the impact of technology on supply and demand. Examples of different types of public goods are provided, with special attention to the cultural sector, to investigate whether and how technology affects the efficiency and the effectiveness of the related public goods provision. The implementation and exploitation of technological advancements are investigated in view of the role of different actors (public, private) at different levels of government.  相似文献

Spillover effects are treated as the influence of knowledge and innovation diffusion on an economic activity, but their analysis related to environmental practices within firms is still quite scarce. This study investigates the effect of environmental practices and related spillovers on productivity and efficiency in agri-food firms located in Southeast Spain. The low investment in research and development actions in comparison with the industrial sector, together with the relatively recent application of environmental requirements and the heterogeneity of environmental controls within firms have led to important changes in the organisation and management of their productive activity. These features are especially related to the implications that location and clustering factors have on environmental knowledge and innovation diffusion. Taking environmental management practices as knowledge of capital, we propose a specific analysis that evaluates the impacts of both environmental investment and spillover on the production function. The results indicate the relationship between productivity improvement and environmental practices, also showing the presence of positive spillovers. In a second-stage analysis, the incidence of environmental variables on the individual technical efficiency of firms is also determined. On the whole, the empirical analysis provides evidence of the links between environmental practices spillovers and economic performance.  相似文献
