The elderly consume more labour‐intensive services than young individuals. This makes them vulnerable to rising costs of services due to higher wages, which can be caused by increased capital accumulation. This paper shows that in a model with a service sector, the golden‐rule capital stock is lower and dynamic inefficiency is more likely to occur than in the conventional one‐sector model. This implies that in many cases, a positive Pay‐As‐You‐Go tax maximises long‐run welfare in a service economy. Calculations based on data from the United Kingdom and the Netherlands show that the long‐run optimal degree of funding coincides with the current situation in these countries.  相似文献

The destruction for ostensibly ideological reasons of the Buddhist statues at Bamyan in Afghanistan by the Taliban (whether or not inspired by Al-Qaeda) raises a number of wider issues. Apart from the problems of minority, dissonant and enclave heritage, there is the question, 'how can relics of the past that are valued in different ways by local, national and international claimants be managed in a way that satisfies all parties?' The idea of world heritage, and its manifestation in international tourism, may conflict with heritage used for local or national purposes. One, if not the most important, actor in this arena, UNESCO, is evaluated on the basis of its goals and efficiency in saving the heritage of mankind in the recent past. The dilemmas inherent in the concept of world heritage and possible solutions for its management are outlined.  相似文献

To support organisations in addressing their safety culture, practical tools have been developed worldwide. Based on such practical tools, it is possible to measure where an organisation is situated regarding its safety culture in order to identify priority areas, formulate appropriate improvement strategies and determine changes over time. In this paper, it is examined which practical tools to measure and improve safety culture are provided on the Belgian market. In total, 15 Belgian tools were identified, of which 8 agreed to cooperate. Amongst the included tools, there is a lot of variation regarding the methods to diagnose the safety culture and the overall procedure to improve the safety culture. The importance to adapt the tool to the specific needs and context of organisations is acknowledged in most of the tools, as well as the importance to use a multi-method approach to measure the safety culture. Also, it is recognised that all hierarchic levels should participate during the process of diagnosing the safety culture. A point of attention is this overall participation during the validation of the results of the diagnosis, and the priority setting of the recommendations, which is mainly done by the higher management. The development of the Belgian tools is based on experience with a focus on direct practical application, which leads to the fact that none of the tools are validated through scientific evidence. Another point of attention is that organisations pay too little attention at the continuity of safety culture research. And finally, the question can be raised if the safety culture tools actually address the concept ‘safety culture’, or if they address only a subset of the concept. When safety culture is addressed, a comprehensive approach should be used, where technological, organisational, human and external aspects are taken into account as interacting and interrelating elements.  相似文献

Against the background of aging societies and increasing life expectancies, the protection of individuals from outliving their savings has become increasingly relevant. Annuities represent insurance against longevity risk and can prevent old‐age poverty. The aim of this article is to present the current state of theoretical, empirical and experimental evidence with regard to annuitization decisions. Toward this end, we conduct a systematic literature review that includes 89 articles. Based on this, we study welfare effects of mandatory annuitization, annuitization rates and the optimal fraction of wealth to be annuitized, as well as determinants of retirees’ choice to annuitize and their impact on annuity demand. Finally, we present possible solutions for overcoming the low uptake of annuities based on its causes. One main result is that behavioral biases in annuitization decisions particularly require considerably more theoretical research and empirical evidence, and that theoretical models already appear to well explain empirically observed annuitization rates.  相似文献

Abstract

Substandard annuities pay higher pensions to individuals with impaired health and thus require special underwriting of applicants. Although such risk classification can substantially increase a company's profitability, these products are uncommon except for the well-established U.K. market. In this paper we comprehensively analyze this issue and make several contributions to the literature. First, we describe enhanced, impaired life, and care annuities, and then we discuss the underwriting process and underwriting risk related thereto. Second, we propose a theoretical model to determine the optimal profit-maximizing risk classification system for substandard annuities. Based on the model framework and for given price-demand dependencies, we formally show the effect of classification costs and costs of underwriting risk on profitability for insurers. Risk classes are distinguished by the average mortality of contained insureds, whereby mortality heterogeneity is included by means of a frailty model. Third, we discuss key aspects regarding a practical implementation of our model as well as possible market entry barriers for substandard annuity providers.  相似文献

This paper analyses the cost of capital of firms with foreign equity listings. Our purpose is to shed light on the question whether international and domestic asset pricing models yield a different estimate of the cost of capital for cross‐listed stocks. We distinguish between (i) the multifactor ICAPM of Solnik (1979) and Sercu (1980) including both the global market portfolio and exchange rate risk premia and (ii) the single factor domestic CAPM. We test for the significance of the cost of capital differential in a sample of 336 cross‐listed stocks from nine countries in the period 1980–99. Our hypothesis is that the cost of capital differential is substantial for firms with international listings, as these are often large multinationals with a strong international orientation. We find that the asset pricing models yield a significantly different estimate of the cost of capital for only 12% of the cross‐listed companies. The size of the cost of capital differential is around 50 basis points for the US, 80 basis points for the UK and 100 basis points for France.  相似文献

The increasing number and influence of charities in the economy, evidence of mismanagement and the need for information for policymaking are all reasons for establishing charity regulators. Public interest and public choice theories explain charity regulation which aims to increase public trust and confidence in charities (and thus increase voluntarism and philanthropy) and to limit tax benefits to specific organisations and donors. Nevertheless, regulation is resource intensive, and growing pressure on government budgets requires efficiencies to be found. This study proposes regulation differentiated according to charities' main resource providers, to reduce costs and focus regulatory effort, and provides a feasible segmentation.  相似文献

This article describes the change processes the Government of National Unity adopted after the 1994 elections in order to transform the South African public service. It shows that the Government is faced with a number of problems (reasons for change) some of which emanate from the legacy of the apartheid past and others from the current situation. Further, the article looks at the vision, mission and objectives set by the Government for the transformation process, while the current change policies and programmes are also highlighted. Finally, the article explores how the Government is dealing with the ethical issues arising from the transformation.  相似文献

Customer value propositions in business markets   总被引:3,自引:0,他引:3  
Examples of consumer value propositions that resonate with customers are exceptionally difficult to find. When properly constructed, value propositions force suppliers to focus on what their offerings are really worth. Once companies become disciplined about understanding their customers, they can make smarter choices about where to allocate scarce resources. The authors illuminate the pitfalls of current approaches, then present a systematic method for developing value propositions that are meaningful to target customers and that focus suppliers' efforts on creating superior value. When managers construct a customer value proposition, they often simply list all the benefits their offering might deliver. But the relative simplicity of this all-benefits approach may have a major drawback: benefit assertion. In other words, managers may claim advantages for features their customers don't care about in the least. Other suppliers try to answer the question, Why should our firm purchase your offering instead of your competitor's? But without a detailed understanding of the customer's requirements and preferences, suppliers can end up stressing points of difference that deliver relatively little value to the target customer. The pitfall with this approach is value presumption: assuming that any favorable points of difference must be valuable for the customer. Drawing on the best practices of a handful of suppliers in business markets, the authors advocate a resonating focus approach. Suppliers can provide simple, yet powerfully captivating, consumer value propositions by making their offerings superior on the few elements that matter most to target customers, demonstrating and documenting the value of this superior performance, and communicating it in a way that conveys a sophisticated understanding of the customer's business priorities.  相似文献
