ABSTRACTIn this paper, Weaver’s six-stage indigenous tourism model is applied to the Lacandon Maya (Hach Winik) of Chiapas, Mexico. Based on a comprehensive review of the anthropological and historical literature on this indigenous group, combined with longitudinal ethnographic and collaborative research performed with tourism entrepreneurs, the Lacandon tourism experience is assessed from the pre-European period until present. By analysing a case study of indigenous tourism in Mexico, a developing country in another geographical region and with a different colonial past, this work supplements Weavers’ perspective. The results show that the fourth and fifth stages of Weaver’s model coincide in this case study, while the sixth stage is still incomplete. Although the Lacandon case has its peculiarities and bearing in mind that several different factors should be considered in the Latin American context, the model proves to be an interesting tool for indigenous tourism analysis in developing countries. 相似文献

By using panel data analysis across 368 water utilities in Mexico over the period 2010–2014, we find that small firms are more efficient than medium and large providers and that increasing production is associated with less efficiency. Billing, income collection and profitability are relevant factors to improve efficiency. Medium and large firms require to measure consumption by service with meters in order to increase efficiency, while small firms do not require it. 相似文献

The paper offers an analysis of empirical evidence on the equity impacts of operational Bus Rapid Transit (BRT) systems in the Global South. The focus is on vertical equity, i.e. whether BRT systems achieve progressive benefits for poorer segments of the population. Findings from Africa, Asia, and Latin America all suggest that BRT does offer significant benefits to low-income groups, in terms of travel time and cost savings, access enhancement, and safety and health benefits. However benefits are often skewed toward medium-income users and thus less progressive than they might be. Two primary reasons for this are insufficient spatial coverage and inappropriate fare policies. While many features of BRT potentially allow it to deliver pro-poor outcomes, such outcomes only materialize if BRT implementers pay specific and sustained attention to equity. The paper identifies key issues that need to be addressed to steer BRT implementation toward more socially sustainable outcomes—including better integration with other transit, paratransit, and nonmotorized transport services, and with the housing sector. 相似文献

This paper analyzes the determination of the optimal environmental regulatory policy under imperfect competition when the firms differ in their polluting technologies and degree of honesty. We show that more honesty does not necessarily imply lower social losses. The effect of honesty in social welfare depends not only on the degree of honesty measured by the proportion of honest firms and their particular cost features but also on the industry structure. 相似文献

The estimation of the population mean when ranked set sampling [rss] is used for selecting the sample and non responses [nr]
are present, is studied. The nr stratum is sub sampled using simple random sampling with replacement. Two strategies are analyzed.
One of them is based on the selection of a sub sample from the nr in each cycle. The other uses sub samples selected among
the nr in each rank.
The accuracy of the proposed estimators is characterized by the corresponding expected variances. Simulations and real life
data are used for analyzing the behavior of them.

Determining factors in entry choice for international expansion. The case of the Spanish hotel industry 总被引:2,自引:0,他引:2
Ana Ramn Rodríguez 《Tourism Management》2002,23(6)
The hotel sector, as a service industry where it is possible to separate capital investment from management skills, is a clear example of how internationalisation can be modelled without shareholding involvement through foreign direct investment. This paper is an empirical examination of the key factors influencing the decision process carried out by Spanish hotel companies in choosing an entry mode for international expansion. The main objective is to verify whether the concepts derived from the transaction-cost, agency and the strategic theories of organisational capability and knowledge in companies can really explain the mode of foreign expansion employed by the Spanish hotel sector. This study will allow comparison of findings on holiday resort hotel chains with other analyses on the international hotel industry. 相似文献

The authors investigate the differences in margins of export and domestic markets for Spanish manufacturing firms in the period 1990 to 1997. They estimate jointly a multiproduct cost function, a variable factor share equation, and two price/marginal‐cost margin equations. The results indicate that the marginal cost of production sold in export markets is slightly greater than in domestic markets. At the same time, the price/marginal‐cost margins in export markets are smaller than in domestic markets. There is also strong evidence that margins are procyclical in domestic markets, but this evidence is less clear in foreign markets. 相似文献
