Trade liberalisation of environmental services, and water services in particular, under the current WTO General Agreement on Trade in Services (GATS), has been widely advocated as a means of increasing private sector participation in the water sector in developing countries. Recognising that effective regulation is needed to ensure that the potential gains from private sector involvement are fully realised, the paper considers the relationship between national regulatory autonomy and GATS liberalisation in water services. The empirical evidence on the impact of private sector involvement in the provision of water services in developing countries is reviewed, and a number of reasons why water privatisation has been problematic in lower‐income countries are identified, including transaction costs and regulatory weaknesses. The study concludes that developing countries with limited regulatory resources should adopt a cautious approach to services liberalisation, by sequencing market liberalisation measures to match the development of their regulatory institutional capacity.  相似文献

An approximate solution to the American put value is proposed and implemented numerically. Relaxation techniques enable the critical price to be determined with high accuracy. The method uses a modification of the quadratic approximation of MacMillan and Barone-Adesi and Whaley which gives an expression for the critical price. Numerical experimentation and iterative methods quickly provide highly accurate solutions.  相似文献

Van der Tas's (1988) I index and the between-country C index introduced by Archer et al. (1995) are competing measures of international harmony. We present comparative statistical properties of these indices, via a simulation study covering three accounting methods in 10 countries, with uniform, bimodal and unimodal distributions of companies across accounting methods. The indices are also adjusted for non-disclosures using techniques developed by Archer and McLeay (1995) and Archer et al. (1995). The I index and the between-country C index are mathematically equivalent in the two-country case even in the presence of non-disclosures. As more countries are compared, the two indices diverge. The means and standard deviations of the I index, with a correction proposed by Archer and McLeay (1995), decrease and there is little skewness or kurtosis. In contrast, as more countries are compared, the between-country C index exhibits more stability in means, lower standard deviations, higher skewness and kurtosis. The between-country C index may be superior to the corrected I index because (i) between-country C index means approximate their ‘expected values’ (where all observations equal expected values) more closely than do corrected I index means: and (ii) between-country C index means are more stable than corrected I index means where the data come from stable distributions.  相似文献

Wendell Bell's idealistic vision of the role of the sociologist in creating a brighter future for society and his theoretical framework of the role of intellectual elites in the decisions of nationhood are examined through the personal lens of a former Caribbean student of the West Indies Study Program at UCLA.  相似文献

Teaching engineering economy at the undergraduate level has changed little over the past century. In fact, it has become stagnant as its focus has turned toward financial mathematics and away from decision analysis. This is seen as a disservice to students who must eventually develop engineering economy studies. This paper provides motivation and suggestions to revitalize the curriculum, including teaching engineering economy in a decision-making context and integrating research advances into the curriculum. From these suggestions, a tested semester outline is presented. In the spirit of this special issue, it is hoped that these suggestions help move the teaching of engineering economy to the “next level” such that we can produce effective decision makers in the critical area of capital investment analysis.  相似文献
