At present, our society and its social security system are not prepared to cope with the challenges resulting from the continuous increase of life expectancy. The traditional concept of disease has to be modified for serving the special needs of the elderly. The optimistic compression of disease theory is an intriguing model, but lacks prove by available data. The anti-aging boom diverts the focus from the social and financial burden that will be unevitably caused by long-term care in the future. If there will not be an — up to now unforeseeable — breakthrough in research, particularly dementia will have an enormous impact on social cost which is often underestimated. 相似文献
Abstract. It is not only the great number of papers written on environment economics that make it worth dealing with this special branch of experimental research, but the environmental problem in all its facets seems to serve as a catalyst for identifying some methodological problems of the experimental method. For this reason, we will not only try to give an overview of recent experiments in environmental economics but also add some thoughts on the methodological implications of this work. We identify three direct connecting factors for the experimental method and environmental economics. First, social dilemmas are, in many cases, at the core of environmental problems. Experiments are able to test theoretical hypotheses for individual behavior in such social dilemma situations. The second connecting factor comes from the field of applied experimental work and can be characterized as the testbedding of institutional arrangements for the solution of environmental problems. The last direct application of experimental methods to environmental economics concerns the individual evaluation of environmental resources. 相似文献
Mark Pauly claims that a "competitive" health care system will solve the health care cost crisis. This article examines how well the competitive solution deals with the five central problems of the health care system: (1) almost universal lack of adequate health insurance for nursing homes and home care; (2) Medicaid's penurious approach to payment for health services for the poor; (3) the emergence of a dual health care system, especially for children; (4) the entrenched waste and inefficiency of the health care system; and (5) consumers' inability to judge the quality of health care. The competitive solution does not eliminate any of these problems--and may not even improve some of them. 相似文献
A link between immigration, imports, and exports has been found by a number of papers that have used the gravity equation to analyze bilateral trade patterns. We discuss what this research implies about the mechanisms through which immigrants expand trade and identify strengths and weakness of the various approaches. This paper also contributes to this literature by estimating immigrant effects for Canada using cross‐province variation in international trade and immigration patterns. We derive an alternative functional form capturing the relationship between immigration and trade based on the proposition that immigrants use their connections and superior 'market intelligence' to exploit trade opportunities that non‐immigrants do not access. We find that the average new immigrant expands exports to his/her native country by $312 and expands imports by $944. 相似文献
This essay introduces a symposium on value and exchange as alternative organizing concepts for the pursuit of economic theorizing. These concepts pertain to two distinct conceptual windows through which economic phenomena can be examined. The immediate inspiration for this symposium was the articulation of Kohn (2004) of the distinction, a distinction that, in turn, was central to the articulation of Buchanan (1964). Furthermore, this distinction is central to the divergent orientations toward economic theorizing that were set forth in the early 1870s by Carl Menger (1971) and Léon Walras (1874). 相似文献
While there is increasing evidence that involving suppliers in new product development (NPD) is important, and for many firms even inevitable, there is also evidence that not all such efforts are successful. Firms aiming at implementing this strategy effectively have to pay close attention to several contingency factors on the organizational level and properly manage supplier involvement on the project level. The exploratory case study research underlying this article explores key issues to be considered when involving suppliers in NPD and the counter measures they can take. Our research shows that companies differentiate between so-called “know-how” and “capacity” projects, and that they manage them differently. Furthermore, this research shows that firms outside the automotive and high-tech manufacturing industries are likely to intensify supplier involvement in the future. 相似文献
The purpose of this study is to examine how scholarly research on luxury brand marketing has evolved in the twenty-first century. This literature review focuses on 242 articles related to luxury marketing. The contributions of these articles are thoroughly analyzed, combining qualitative interpretations with bibliometric citation analysis that uses a social network of referrals. This study identifies the most influential universities, research outlets, and scholars in the recent evolution of luxury marketing research. The study also identifies current and future research streams, geographic scope, and underlying research methodologies, and it reveals the most frequently used theories and prominent constructs in luxury marketing research. There are few studies that have examined the literature review of the luxury marketing discipline. No previous research has investigated luxury branding by means of a bibliometric analysis and qualitative assessment within such a large scope. Building on the results of this analysis, researchers can target their studies precisely and, thus, increase the contributions of their empirical research.
