Smart cities initiatives are developing all over the world, due to their support in favouring a better provision of services, in connection with the aim of achieving efficiency in cities management. More and more big corporations are interested in this topic to develop their businesses, as several issues are linked to these projects, like environment, water management, energy policies, education, culture, and so on. In literature these issues, known as drivers, were also related to sustainability aims which could be reached through the accomplishment of better performances within environment, economy, and society. This study synthesizes all the different drivers identified by scholars and industry players in a model, in order to use it as a framework to depict the linkages among the various smart cities projects. Since transport resulted as one of the most considered drivers in the analyzed contributions, the research questions were delineated to describe its role in the different phases of smart initiatives, and to understand if it could encourage and enable the other drivers' development. The multiple case study was chosen as the fittest methodological approach and it was conducted with the selection of three smart cities, one for each of the most cited platform models developed by industry players, which had started transport initiatives at least three years ago: Singapore (IBM), Amsterdam (Accenture), and San Francisco (Microsoft). The analysis of the official documents set up by city departments and by the industry players showed transport as a driving force in smart cities projects which conveys a smart approach to different domains, especially energy savings, environment, and safety. The results also showed smart mobility as a pivot in stimulating investments and citizens' participation on different city drivers, especially as it concerns environment and services to both citizens and businesses.

Forward-looking disclosures are a crucial source of information when valuing a company. We study the effect of forward-looking disclosures on analysts' forecast properties, in particular accuracy and dispersion. Our sample includes all the non-financial firms from Italy, Germany, France and Switzerland that in year 2002 were cross-listed on local stock exchanges and on the New York Stock Exchange. We conduct a content analysis on the Annual Report and the 20F form of these companies for the years 2002, 2003 and 2004. We differentiate between forward-looking information on the basis of the disclosure of expected effects on future financial performance and the disclosure of a measure of this impact. We define forward-looking information disclosed with the characteristics of being quantified and directed (and financial) as financially verifiable as it facilitates the comparison with its subsequent realisation in relation to expected future financial performance. Our analysis finds support for the theoretical prediction that verifiable disclosures are more effective than unverifiable disclosures at improving accuracy and reducing dispersion of analysts' forecasts. Our sample also allows us to explore the effects of the difference between the degrees of verifiability between forward-looking disclosures of the 20F form versus those of the domestic annual report. Our analysis provides empirical support for the hypotheses that these differences are significant and have a significant effect on forecast properties.  相似文献

The view that corporate psychopathy played a significant role in causing the global financial crisis, although insightful, paints a reductionist picture of what we present as the broader issue. Our broader issue is the tendency for psychopathy, narcissism and Machiavellianism to cluster psychologically and culturally as ‘dark leadership’ within global financial institutions. Strong evidence for their co-intensification across society and in corporations ought to alarm financial regulators. We argue that an ‘ethical revival’ of prudence within prudential regulation ought to be included in any package of solutions. Referencing research on moral muteness and the role of language in framing thoughts and behaviours, we recommend that regulators define prudence in an explicitly normative sense, an approach that may be further strengthened by drawing upon a widely appealing ethic of intergenerational care. An ethical revival of prudence, we argue, would allow the core problems of greed and myopia highlighted by corporate psychopathy theory to be addressed in a politically sensitive manner which recognises the pitfalls of regulating directly against corporate psychopathy. Furthermore, it would provide a viable conceptual framework to guide regulators along the treacherous path to more intrusive cultural regulation.  相似文献

Abstract

The Values Theory adopts a generic framework whereby a set of values is employed across consumer decision-making contexts in a manner that makes no distinction among various product categories. The present study advances this theory by exhibiting the adaptation capability of the generic values instrument (the Portrait Value Questionnaire, PVQ), demonstrating that tailor-made PVQ versions can reflect consumers' motives towards differentiated products (i.e. organic foods). A questionnaire was completed by approximately 1000 households in each of eight EU countries (N?=?8171). The organic food-relevant PVQ was developed through a preliminary qualitative phase (i.e. a means-end chain analysis), and its factorial design was validated through CFA, showing high statistical performance. PVQ-based European clusters with strong self-transcendence values comprised large numbers of organic purchasers. Moreover, results point to the fact that when a circumplex taxonomy, such as the PVQ, is applied in a real context (i.e. organic food purchases), the situation-relevant value domains merge into new hierarchical dimensions in absolute respect of the original taxonomy. This conclusion points to PVQ's robustness in adaptability to different situations of human value perspective.  相似文献

We study the emergence of strategic behavior in double auctions with an equal number of buyers and sellers, under the distinct assumptions that orders are cleared simultaneously or asynchronously. The evolution of strategic behavior is modeled as a learning process driven by a genetic algorithm. We find that, as the size of the market grows, allocative inefficiency tends to zero and performance converges to the competitive outcome, regardless of the order-clearing rule. The main result concerns the evolution of strategic behavior as the size of the market gets larger. Under simultaneous order-clearing, only marginal traders learn to be price takers and make offers equal to their valuations/costs. Under asynchronous order-clearing, all intramarginal traders learn to be price makers and make offers equal to the competitive equilibrium price. The nature of the order-clearing rule affects in a fundamental way what kind of strategic behavior we should expect to emerge.  相似文献

Innovation processes are increasingly spreading through the unbounded universe of European small and medium enterprises (SMEs). It represents a fundamental opportunity especially for those SMEs operating in the so‐called ‘green economy’ sectors, in order to be competitive in a National, European and International market with their sustainable products and services. Drawing upon a database of over 300 enterprises operating within the eight defined green sectors, this paper assesses the determinants and drawbacks of innovation. In particular, by using an econometrical approach, we tested the following propositions: (1) small dimension of enterprises is not an obstacle to their innovation capabilities; (2) the adoption of an internationalisation strategy is an opportunity and a stimulus to innovation for SMEs; (3) cooperation with research centres, financial partners, trade association and public entities can help SMEs to overcome difficulties and help them to develop and offer innovative products and services, so to be competitive at an international level. The econometric analysis shows a positive impact of the variables ‘dimension’ and ‘level of internationalisation’ on innovation capabilities. In addition, cooperation with research centres and access to capital market are positively related with effective innovations.  相似文献

We present the results of the first experimental study of financial markets contagion. We develop a model of financial contagion amenable to be tested in the laboratory. In the model, contagion happens because of cross-market rebalancing, a channel for transmission of shocks across markets first studied by Kodres and Pritsker (2002). Theory predicts that, because of portfolio rebalancing, a negative shock in one market transmits itself to the others, as investors adjust their portfolio allocations. The theory is supported by the experimental results. The price observed in the laboratory is close to that predicted by theory, and strong contagion effects are observed. The results are robust across different market structures. Moreover, as theory predicts, lower asymmetric information in a (“developed”) financial market increases the contagion effects in (“emerging”) markets.  相似文献

In the Spanish automobile market between 1990 and 2000, significant reductions in tariff and nontariff protections increased the complexity of the product space, through the penetration of new car brands and models. Acknowledging these environmental dynamics, this study details conditions in which across‐niche (product breadth or intraindustry diversification) and within‐niche (product depth or versioning) product proliferation exerts a positive relationship on firm performance, as well as how key relationships change according to the complexity of the product space in the industry.
