Rwanda's Nyungwe National Park is a biodiversity hotspot with the most endemic species in the ecoregion and the highest number of threatened species internationally. Nyungwe supplies critical ecosystem services to the Rwandan population including water provisioning and tourism services. Tourism in the Park has strong potential for financing enhanced visitor experiences and the sustainable management of the Park. This paper explores quantitatively the economic impacts of adjustment in Park visitation fees and tourism demand as a source of revenues to improve Park tourism opportunities and ongoing operations and maintenance. The methods developed in this paper are novel in integrating the results of stated preference techniques with a regional computable general equilibrium modelling approach to capture multisectoral, direct, indirect and induced impacts. Such methods have strong potential for assessing revenue generation alternatives in other contexts where park managers are faced with the need to generate additional revenue for sustainable park management while facing diminishing budget allocations. Results of this analysis demonstrate that adjustment of Park fees has a relatively small impact on the regional economy and well-being when compared with a strategy aimed at generating increased tourism demand through investment in improving the visitor experience at Nyungwe National Park.  相似文献

Union member attachment research has generally examined large unions organizing large employers. The present study presents a conceptual model and related data concerning various aspects of the union attachment expressed by individuals in small bargaining units. The results show differences among individuals in commitment based on their union experiences and demographic characteristics. Résumé Les études traitant de la loyatué qu'éprouvent les membres envers leur syndicats examinent généralement des syndicats importants au sein d'entreprises de taille. La présente étude offre un modèle conceptuel et les données relatives aux divers aspects de la loyauté exprimée par des individus appartenant à de petites unités de négociations. Les résultats démontrent les différences de loyauté chez les membres selon leur experience syndicale et les caractéristiques démographiques.  相似文献

Simple organizations, composed of operatives and one manager, may be organized as a hierarchy with the manager appropriating all profits or as a partnership with (say) equal shares of profits. Conditions on profitability and the optimal span of control are analyzed. Next, partnerships are considered and alternative incentives and distributions are compared. When partners are free to choose their time inputs, then a sufficiently high preference for leisure as against income will make a partnership more attractive even though it is less profitable.  相似文献

This article re–evaluates the gravity of the financial problems facing British voluntary hospitals in the interwar period. A relational database of statistics on hospital provision, finance (at both current and constant prices), and activity is used to derive consistent sets of hospitals for reporting purposes. The article presents novel analyses of the extent and pattern of hospital surpluses and deficits; of the capital accounts of selected individual hospitals; of trends in hospital expenditure; of the diversification of hospital income, emphasizing the declining importance of traditional philanthropy; and of the effect of these changes on hospital provision and utilization.  相似文献

This paper proposes a contemporaneous-threshold multivariate smooth transition autoregressive (C-MSTAR) model in which the regime weights depend on the ex-ante probabilities that latent regime-specific variables exceed certain threshold values. A key feature of the model is that the transition function depends on all the parameters of the model as well as on the data. Since the mixing weights are also a function of the regime-specific noise covariance matrix, the model can account for contemporaneous regime-specific co-movements of the variables. The stability and distributional properties of the proposed model are discussed, as well as issues of estimation, testing and forecasting. The practical usefulness of the C-MSTAR model is illustrated by examining the relationship between US stock prices and interest rates.  相似文献
