World tourism cities perform multiple functions and exhibit various characteristics that influence tourism development within their boundaries. They are the main gateway for tourists visiting a country and their success has a direct impact on the visitor economy of that destination. London, the focus of this research, has been one of the world’s top tourism cities for many years, and a key gateway for domestic and international visitors. But despite the important role tourism plays in the economy of the city, there is limited research on the development of this activity in the capital. Using London as an exploratory case study, this paper contributes to better understanding the challenges faced by policy makers when planning and managing tourism in world cities. The adopted research method offers the advantage of gathering insightful information using multiple data collection techniques. Examining this new evidence contributes to expanding the knowledge on the particularities of tourism development in one of the top world cities, which could help policy makers in their efforts to better prepare for potential challenges faced by these complex but important destinations.  相似文献

The aim of this research is to investigate the web of business-stakeholder relationships emerging from first integrated reports. Drawn from the stakeholder salience theory, the analysis focuses on some factors that may cause specific stakeholders to be crucial for some organizations and their ability to create value over time. More precisely, findings highlight the importance of industry membership, while entities’ nationality seems not to be a differentiating element. This study contributes to the corporate disclosure literature by analyzing an emerging reporting tool, the integrated report, and demonstrating that the link between some business characteristics and stakeholder salience seems fundamental for the representation of the impact of corporate social and environmental responsibilities on the economic performance. From a practical point of view, the impact of industry membership on corporate disclosures encourages the drafting of differentiated reporting standards across sectors, in order to improve comparability, materiality, and reliability of information.  相似文献

The Pan American Health Organization (PAHO), Regional Office of the World Health Organization, is a United Nations agency specializing in providing technical cooperation in health to the countries of Latin America and the Caribbean. A futures approach has much to offer in this endeavour, and PAHO is making health futures tools available to its Member States through a variety of activities. The purpose of promoting futures thinking and the application of futures tools is to improve health-policy planning and public health action within the framework of the ‘Health for All’ vision and PAHO's current Strategic and Programmatic Orientations.  相似文献

The Singapore Exchange (SGX), a small satellite market, successfully competes with a large home market, the Osaka Securities Exchange (OSE), in trading the Nikkei 225 futures index. In this paper, we investigate the contribution of the SGX to price discovery and shed light on the reasons for its continued success. Evidence is provided from information revelation and price discovery of three competing but informationally linked markets of the Nikkei 225 index—domestic spot (Tokyo Stock Exchange), domestic futures (OSE), and foreign futures (SGX), which represents the satellite market. Overall, the futures market contributes 77% to price discovery, with the satellite market contributing 42% of the futures and 33% of the total price discovery. These figures, surprisingly, far exceed the satellite market's share of trading volume. Support is provided for the extended trading hours on the SGX for three of the four non‐overlapping trading sub‐periods. © 2004 Wiley Periodicals, Inc. Jrl Fut Mark 24:981–1004, 2004  相似文献

The margin system is the first line of defense against the default risk of a clearinghouse. From the perspectives of a clearinghouse, the utmost concern is to have a prudential system to control the default exposure. Once the level of prudentiality is set, the next concern will be the opportunity cost of the investors, because high opportunity cost discourages people from hedging futures, and thus defeats the function of a futures market. In this article, we first develop different measures of prudentiality and opportunity cost. We then formulate a statistical framework to evaluate different margin‐setting methodologies, all of which strike a balance between prudentiality and opportunity cost. Three margin‐setting methodologies, namely, (1) using simple moving averages; (2) using exponentially weighted moving averages; (3) using a GARCH approach, are applied to the Hang Seng Index futures. Keeping the same prudentiality level, it is shown that the one using a GARCH approach by and large gives the lowest average overcharge. © 2004 Wiley Periodicals, Inc.

Research on ethnic residential patterns is overwhelmingly empiricist in focus. The discursive context surrounding the socio‐spatial phenomenon needs to be acknowledged since it can have concrete impacts on the practice of urban social planning as well as the spatial behaviour of individuals and groups. Using Henri Lefebvre's insights into the production of social space, this article looks at how a dominant representation of space is constructed, with its implications for ‘lived’ spaces and the spatial practices which circumscribe them. The case of Singapore is examined, where the government has appropriated the discourse surrounding ‘ethnic regrouping’ in an attempt to legitimize the unpopular policy of ethnic quotas in public housing. Alleging that ‘ethnic regrouping’ had been taking place during the 1980s, this was portrayed as undesirable and contrary to the ideal of integration. The imposition of ethnic quotas was thus justified as necessary and appropriate. Systematic analysis using the index of dissimilarity, however, problematizes this representation of space. The rhetoric surrounding ethnic regrouping is revealed to be a means of social discipline whereby the government imposes a particular representation of space and seeks to manipulate the social landscape via technocratic means. Les recherches sur les modèles résidentiels ethniques débordent d'empirisme. Or, le contexte discursif du phénomène socio‐spatial doit être reconnu puisque celui‐ci peut avoir des incidences tangibles sur l'exercice de l'urbanisme social, ainsi que sur le comportement des individus et groupes dans l'espace. A partir des idées d'Henri Lefebvre sur la production de l'espace social, l'article analyse comment s'élabore une représentation dominante de l'espace, avec ses implications sur les espaces ‘vécus'et les pratiques spatiales qui les délimitent. Dans le cas de Singapour, le gouvernement s'est approprié le discours autour du ‘regroupement ethnique’ dans le but de légitimer la politique impopulaire des quotas ethniques dans les logements publics. Sous le prétexte que le ‘regroupement ethnique’ s'était déroulé dans les années 1980, il a été présenté comme indésirable et contraire à l'idéal d'intégration. Les quotas ethniques ont donc été justifiés comme nécessaires et pertinents. Cependant, une analyse systématique utilisant l'indice de dissemblance remet en cause cette représentation de l'espace. La rhétorique entourant le regroupement ethnique apparaît comme un outil de discipline sociale grâce auquel le gouvernement impose une représentation particulière de l'espace, cherchant à manipuler le paysage social par des moyens technocratiques.  相似文献

This paper provides further evidence of price and volume effects associated with index compositional changes by analysing the inclusions (exclusions) from the French CAC40 and SBF120 indices, as well as the FTSE100. I find evidence supporting the price pressure hypothesis associated with index fund rebalancing, but weak or no evidence for the imperfect substitution, liquidity and information hypotheses. The results improve on recent evidence from the S&P500 index. The evidence for the FTSE100 additions shows, in particular, that markets learn about an imminent inclusion and incorporate this information into prices, even before the announcement date.  相似文献

This paper presents and analyses the differences in the eco-models implemented worldwide (such as whether and how carbon taxes being "recycled"), or in their efficiency parameters (inconsistent parameter values that account for different results). This is the assumption that a real tradeoff exists between the production of environmental goods. The present article empirically proves that something must be given up in order to gain something else, and once equations are specified to trace out the path of the economy over time, the natural economic formulation of such equations will embody the notion of economic and bio-tradeoffs.  相似文献

Since the regional scale turns out to be the scale at which fiscal devolution is likely to be accomplished in Italy, and that at which trade and growth interdependencies as well as regional convergence can be most conveniently investigated, a new 20-region input–output model for Italy seems to be a useful tool of analysis. Although various regional and interregional models have been constructed since the 1950s, none has been implemented for the whole system of 20 Italian administrative regions considered in their tight mutual dependence; also, the pool approach has not been greatly favoured, even in situations where direct information on regional trade is lacking. The main purpose of this paper is to report on the structure of the model, the rather complex procedure used in the model construction and the adopted solution technique. Some space is devoted to the problems encountered in handling regional trade endogenously in an input–output setting and to a comparison between the pool approach, used in the Italian model, and other current techniques. The paper also reports on some preliminary results regarding the regional impact of fiscal policy.  相似文献
