In 1996 the Heavily Indebted Poor Countries (HIPC) Initiative was launched by the Bretton Woods institutions to reduce the
external debt burden of low-income countries (LICs) to sustainable levels in a reasonably short period of time because debt
constitutes an obstacle to sustainable economic growth and poverty reduction. In some HIPCs, however, debt sustainability
has been in danger despite debt relief under the HIPC Initiative. Debt relief is a necessary but not a sufficient condition
for development. It can do no more than play a catalytic role. The question, then, is how to achieve debt sustainability beyond
the HIPC Initiative. 相似文献

Recurrent tasks such as pricing, calibration and risk assessment need to be executed accurately and in real time. We concentrate on parametric option pricing (POP) as a generic instance of parametric conditional expectations and show that polynomial interpolation in the parameter space promises to considerably reduce run-times while maintaining accuracy. The attractive properties of Chebyshev interpolation and its tensorized extension enable us to identify broadly applicable criteria for (sub)exponential convergence and explicit error bounds. The method is most promising when the computation of the prices is most challenging. We therefore investigate its combination with Monte Carlo simulation and analyze the effect of (stochastic) approximations of the interpolation. For a wide and important range of problems, the Chebyshev method turns out to be more efficient than parametric multilevel Monte Carlo. We conclude with a numerical efficiency study. 相似文献

We examine the willingness to pay (WTP) for green products in air travel. Green products in aviation are supplementary services, which are sold on top of the travel service (e.g. carbon offsets, organic on‐board food). We identify a set of potential green products in aviation and report the preferences for additional airline services of 811 Swiss air travellers using an adaptive choice‐based conjoint survey. We find that 20% of those passengers who are interested in purchasing supplementary services show a considerable WTP for green products. The green segment differs from the regular segment only in terms of behavioural features, not in terms of demographic or socio‐economic characteristics.

Using Bourdieu??s Habitus-Capital theory and a representative dataset this study shows that social position influences internet use. The study is thus connected to the research about thedigital divide. A secondary analysis of the ACTA 2008 (n?=?7.623, representative of Germans between 14 and 64 years who use the internet) shows on the one hand that there are still gaps in internet usage (gender, generation, and education gap). On the other hand the results indicate acapital gap. Since the accumulation of capital in the internet is connected with education as well as economic status, there is a threat of a downward spiral: Those who have less capital (education, money) gather less internet knowledge. Since cultural capital influences a person??s social position, internet use enhances social inequality. 相似文献

This systematic review analyses literature on the work of hybrid value creation, i.e. the process of generating additional value by innovatively combining products (tangible component) and services (intangible component). A state of the art report on hybrid value creation is delivered by first systematically identifying and then analyzing 169 publications focusing on hybrid value creation. The identified publications are clustered into eight categories based on their links and interactions and thus a mapping of this evolving field is suggested. A discussion and reflection of the findings with respect to the pervasiveness of literature and the research methodologies used is provided. The paper concludes by identifying some dominant strategic gaps in the overall research landscape and provides directions for future research. 相似文献

This article contributes to the debate on the link between reciprocal motives of employees and HRM practices by studying the behavioral effects of intra-firm trainings on absence behavior and turnover probability. We apply the gift-exchange framework and offer a behavioral perspective that helps to explain why firms invest in trainings that provide mainly general skills. We argue that employees may reciprocate the gift of firm-sponsored training with higher levels of costly effort or commitment. We employ a stringent methodological approach based on panel data of a large multinational firm and find that, in contrast to human capital predictions, general trainings lead to a decrease in turnover rates. Most notably, we find the strongest effect for employees with the lowest levels of firm tenure. This is a quite novel result as this group should face the lowest separation costs, for instance, due to the accumulation of firm-specific human capital. Hence, intra-firm trainings are an important retention device, especially for newly or recently hired employees. Furthermore, a short-term decrease in absenteeism indicates a temporary, reciprocal reaction by employees. 相似文献

Besser essen im Krankenhaus - Essen kann glücklich machen. Essen kann aber
auch belastend sein. Gerade im Krankenhaus verschl?gt es vielen Senioren den Appetit.
Es liegt in der Verantwortung der Pflegenden, sich dieses Problems anzunehmen. Doch
wie gelingt es, auch unter schwierigen Bedingungen, den Bedürfnissen der Patienten
gerecht zu werden? 相似文献

Finland is undergoing a rapid change from a homogenous culture to a heterogeneous culture. With immigrants from all over the world making Finland their home, a lot of multicultural integration work is needed. Collaborative learning in peer groups can work as a useful framework for enhancing tolerance toward differences, and consumer education and home economics education offer a fruitful setting for this kind of collaborative teaching of tolerance. In particular, the practical nature of consumer education and home economics makes it suitable to teach multiculturalism in a daily life setting. In this study, 10 integration projects in Finland were examined through a qualitative summary to reveal the key elements in successful multicultural integration work. The focus was on multicultural, collaborative interactions. The results show that problems are bound to arise when people from different cultures meet. Daily life situations, culturally unequal settings, poor participation and a lack of real interaction between different cultural groups can be problematic. These problems need to be overcome before the richness of different cultures can be revealed. People need to learn how to use the tools of multicultural and collaborative learning before the group can act successfully. 相似文献
