Many studies have considered the probability that a pairwise majority rule (PMR) winner exists for three candidate elections. The absence of a PMR winner indicates an occurrence of Condorcet's Paradox for three candidate elections. This paper summarizes work that has been done in this area with the assumptions of: Impartial Culture, Impartial Anonymous Culture, Maximal Culture, Dual Culture and Uniform Culture. Results are included for the likelihood that there is a strong winner by PMR, a weak winner by PMR, and the probability that a specific candidate is among the winners by PMR. Closed form representations are developed for some of these probabilities for Impartial Anonymous Culture and for Maximal Culture. Consistent results are obtained for all cultures. In particular, very different behaviors are observed for odd and even numbers of voters. The limiting probabilities as the number of voters increases are reached very quickly for odd numbers of voters, and quite slowly for even numbers of voters. The greatest likelihood of observing Condorcet's Paradox typically occurs for small numbers of voters. Results suggest that while examples of Condorcet's Paradox are observed, one should not expect to observe them with great frequency in three candidate elections. 相似文献

When a risk is exchanged, the exact value for the minimum price (positive or negative) that the purchaser (investor, or insurer) is willing to pay is given by the certainty equivalent wealth level, which in turn depends on his specific utility function. When this utility function is unknown, then only a sufficient condition on the price can ever be found. This paper provides methods for calculating such a sufficient condition, when only limited information on the utility function is known. 相似文献

We employ an empirical general equilibrium model of the CAP to determine which factors and countries would be expected to be opposed to or support reform of the CAP. The objective is to determine who are the “friends” and “enemies” of the CAP. The analysis studies the extent to which lobbying activity by these interested parties could be expected to encourage or discourage internal EU reform of the CAP. Several alternative policies to reform the CAP are evaluated in this manner in order to determine if one or another set of policies has a greater chance of being accepted. Specifically, we study the Uruguay Round Agreement, as well as a number of stated negotiating positions presented during the Round. The result will be a summary assessment of the relative politico-economic acceptability of these reform proposals within the EU. Our results lead to a very simple policy conclusion. Given the set of policy packages considered here, there is little doubt that the EU was most inclined to adopt a proposal incorporating compensation payments. Without further disaggregation of the analysis to identify the United States or Japan, we can only note that such a proposal is also the best as far as overall welfare goes for the rest of the world. Our results confirm the importance of sidepayments in the implementation of the Uruguay Round Agreement. 相似文献

The articles in this issue illuminate psychosocial issues raised by the development and delivery of new medical technologies. Five kinds of questions surface repeatedly: questions about a technology's purpose(s), the value judgments it presumes, the locus of its control, the external forces that drive it, and its long-term social risks. These questions take the discussion of new technologies beyond the challenge of improving access to their benefits. They also raise issues that will become increasingly important as the capabilities of medical technology expand. For example, they suggest research questions for three other emerging medical technologies: use of biosynthetic growth hormone to treat short stature in hormonally normal children, genetic tests on fetal cells from the circulating maternal blood, and development of clinically reliable biomarkers of the aging process. Part Three of this issue provides a theoretical basis for encouraging psychosocial perspectives in this area, by illustrating the central role that "robust," multifaceted analysis has come to play within the methods of bioethics. 相似文献

Australian University Students' Views of the Nuclear Arms Race: Comparative and Qualitative Analyses
Jeanette A. Lawrence Philip Jennings Agnes E. Dodds Irene M. Styles 《The Australian journal of social issues》1991,26(3):191-209
Australian university students' views of the nuclear arms race were analysed in two studies. A sample comparison study used Nuclear Arms Race Questionnaire (NARQ) and Position on Nuclear Weapons (PNW) scales to compare university students' views with those of high school students and community groups. University students' views were more strongly anti-nuclear than middle income and Middle European migrant groups, but not more than high school student and church member groups'. Females' attitudes were more strongly anti-nuclear than males. A qualitative analysis of ten university students' formulations of the arms races problem and Australia's involvement revealed the complex dimensions of perceived relationships between global and national interests and personal nuclear issues. Students' solutions were directly related to their formulations of the major aspects of the arms race problem, with six students who represented the nuclear problem in terms of superpower conflict, seeing individuals as powerless to influence solutions. Quantitative trends are interpreted in light of the varied representations of the problem and the association of students' generally anti-nuclear attitudes with lack of involvement in the peace movement. 相似文献

A computationally viable choice function possesses, in addition to other important properties, adaptability - as new alternatives become feasible the set of best alternatives corresponding to the new feasible set can be located without having to reconsider previously rejected alternatives. Adaptability is shown to be closely related to, in fact characteristic of, the standard notions of rationality (expressed in terms of transitivity properties). Adaptability provides a generalization of conventional rationality and in addition leads to the choice function proposed by Schwartz, albeit from an entirely different route, that of computational viability. 相似文献

The Australian Labor Government has outlined how it intends to finance the proposed Health Insurance Programme in its recent white paper on Health Insurance, whilst the specific details are provided in the earlier Deeble Report. From these documents two important conclusions emerge. Firstly, the Government does not really know how much the scheme will cost. Secondly, the proposed methods of financing has a number of contentious aspects. It is with these two matters that this paper is concerned. 相似文献

"以人为本"包含着诸多歧义,马克思主义在科学实践观的基础上,运用唯物辩证法和历史辩证法阐明了"以人为本"的科学内涵.从管理伦理学的视角来看,科学理解的"以人为本"是管理伦理学"何以可能"的本体论前提和承诺,是管理伦理学学科建构的基本原则,是管理伦理学的终极价值追求和理论归宿. 相似文献

This paper presents an axiomatic characterization of the Owen set of transportation games. In the characterization we use six properties including consistency (CONS2) and splitting and merging (SM) which are firstly proposed and defined for this setup in the present paper. 相似文献
