Part I of this paper offers a novel result in social choice theory by extending Harsanyi's well-known utilitarian theorem into a multi-profile context. Harsanyi was contented with showing that if the individuals' utilities u
i are von Neumann-Morgenstern, and if the given utility u of the social planner is VNM as well, then the Pareto indifference rule implies that u is affine in terms of the u
i. We provide a related conclusion by considering u as functionally dependent on the u
i, through a suitably restricted social welfare functional (u
1,...,u
n)u=f(u
1,...,u
n). We claim that this result is more in accordance with contemporary social choice theory than Harsanyi's single-profile theorem is. Besides, harsanyi's initial proof of the latter was faulty. Part II of this paper offers an alternative argument which is intended to be both general and simple enough, contrary to the recent proofs published by Fishburn and others. It finally investigates the affine independence problem on the u
i discussed by Fishburn as a corollary to harsanyi's theorem.The authors are indebted to L. Haddad, A. Sen and two anonymous referees for useful written comments. They also benefited from stimulating remarks in seminars and helpful conversations with their colleagues. The usual caveat of course applies.

We investigate a general theory of combining individual preferences into collective choice. The preferences are treated quantitatively, by means of preference functions (a,b), where 0(a,b) expresses the degree of preference of a to b. A transition function is a function (x,y) which computes (a,c) from (a,b) and (b,c), namely (a,c)=((a,b),(b,c)). We prove that given certain (reasonable) conditions on how individual preferences are aggregated, there is only one transition function that satisfies these conditions, namely the function (x,y)=x·y (multiplication of odds). We also formulate a property of transition functions called invariance, and prove that there is no invariant transition function; this impossibility theorem shows limitations of the quantitative method.Research supported in part by the National Science Foundation. 相似文献

Compliments are often viewed primarily as a linear event in which one person expresses approval or admiration of another. Far less attention has been given to the circular nature of compliments and the manner in which they enhance the positions of both the giver and the receiver of the compliment. Therapeutic compliments have proven to be highly effective means of motivating clients, while at the same time increasing therapeutic leverage. This article proposes that compliments should be purposefully given, and that the type of compliment should vary with the stage of therapy and the intended response of the client to the compliment. 相似文献

Recent research on the impact of labor migration on the socioeconomic development of developing countries has provided opportunity to try and resolve some of the long-standing polemics that have pervaded the literature on migration and development. This article focuses on findings concerning the labor, remittance, and social impacts of emigration on countries that have participated in labor emigration. While a great deal more research needs to be done, recent findings confirm that in some situations the sort-term impacts of labor migration on sending countries have been considerable. 相似文献

Demographics: people and markets 总被引:1,自引:0,他引:1
The basics of demography are now basic to us business as well. Demographics combine demographic data with socioeconomic and geographic factors to help business and other managers know the market for their goods and services. This pamphlet explains market, product, and site analyses, discusses data sources and resources, and includes case studies involving major corporations. Post-war population trends have had an enormous impact on consumer and labor markets, bringing home to business the importance of taking advantage of demographic shifts. Advances in computerized access to data describing changes and increased consciousness of their economic significance has spurred the application of demographic knowledge by managers and the growth of the demographics information industry. The pamphlet describes the resources and methods of demographics including the creation and use of demographic data products. 相似文献

"Net undercount rates in the U.S. decennial census have been steadily declining over the last several censuses. Differential undercounts among race groups and geographic areas, however, appear to persist. In the following, we examine and compare several methodologies for providing small area estimates of census coverage by constructing artificial populations. Measures of performance are also introduced to assess the various small area estimates. Synthetic estimation in combination with regression modelling provide the best results over the methods considered. Sampling error effects are also simulated. The results form the basis for determining coverage evaluation survey small area estimates of the 1900 decennial census." 相似文献

The author examines the content and methodology of the 1989 Soviet census. Items to be included in the questionnaires for both the total population and the 25 percent sample survey are described. The author notes that questions on housing will be included for the first time. Other topics considered include reliability of data, confidentiality, and organization. 相似文献

Social workers are required to collect a considerable amount of personal information about clients and their families which may be unrelated to direct clinical work. Administrators often use this for the purpose of payment, service documentation, agency planning, and accountability. The worker's concern about the appropriateness of collecting this data may result in poor compliance or even falsification of information. In a survey of Minnesota social workers, noncompliance with data collection requirements was substantial. The authors also found a significant degree of conflict about privacy and confidentiality issues. These findings suggest a basis of concern for those who must rely on accurate data for administrative planning. 相似文献

The author argues that the burden of proof for the safety and efficacy of some medical devices properly lies with the manufacturers of the devices and with the providers who use them. The controversy over breast implants is used as a case for this shift in the burden of proof of safety and effectiveness. 相似文献
