Reducing the level of switching costs in mobile communications: The case of Mobile Number Portability 总被引:1,自引:0,他引:1
Switching costs are one of the most important economic forces that affect market competition in mobile communications. Both theoretical and empirical studies have shown that switching costs reduce market competition leading to higher prices, lower product and service quality, and lower customer welfare. Given their negative consequences, national regulatory authorities have designed policies aimed at reducing switching costs and fostering competition. One of the most important of these, in the mobile communications industry, is mobile number portability (MNP). The aim of this paper is to investigate the effect of MNP on switching costs in mobile phone services. First, a hierarchical Bayes model is proposed to measure switching costs at the customer level and to investigate the impact of MNP on them. Second, this study examines the drivers of MNP adoption by customers using a binary logit specification. The results reveal that this regulatory policy has significantly reduced the cost of switching and that MNP adoption partially depends on customer-related variables. 相似文献

Nitrate pollution control under soil heterogeneity 总被引:1,自引:0,他引:1
This article presents results on measures to abate nitrogen pollution when soil heterogeneity is considered by using a dynamic model of corn production. Several policy options for the control of nitrate pollution are evaluated by their cost efficiency. While results show that a nitrogen standard or tax is a good second-best control instrument, neglecting dynamics may lead to the wrong choice of instrument. Other important findings for the design of nonpoint pollution policy measures are that water pricing, as advocated by the Water Framework Directive, is inefficient as a pollution abatement tool, and differentiating control measures by soil type enhances welfare, although welfare gains may be small. 相似文献

Visitor learning is a basic component of community-based ecotourism (CBET), yet has seldom been the subject of research. This study examines how local environmental, cultural and livelihood knowledge comprise the ecotourism curriculum in two CBET projects located in southern Thailand and Cambodia, respectively. Following an accounting of local ecotourism curriculum content and teaching pedagogies employed at present in the two projects, recommendations are made for enhancing visitor learning in CBET. These include curriculum development, which recognizes and incorporates the particular forms of local knowledge present in a given CBET community, and the application of pedagogies of experiential and transformative learning in the teaching of this curriculum. 相似文献

This paper considers the problem of allocating shares of irrigation water to different agricultural agents with single-peaked preferences with respect to their own shares. We define two different sequential allocation rules that respect the asymmetry between the agents and maintain the properties of Pareto efficiency and strategy-proofness, and we design a specific algorithm to apply these rules. The results of the empirical application of these rules for the case of an irrigated area located in the Ebro Basin (Spain) show that the designed sequential rules are able to substantially improve the efficiency of the currently applied proportional rule in context of severe scarcity of water and/or high administrative water prices. 相似文献
