Summary. This research studies the role of multivariate distribution structures on random asset returns in determining the optimal
allocation vector for an expected utility maximizer. All our conclusions pertain for the set of risk averters. By carefully
disturbing symmetry in the distribution of the, possibly covarying, returns, we ascertain the ordinal structure of the optimized
allocation vector. Rank order of allocations is also established when a permutation symmetric random vector is mapped into
the returns vector through location and scale shifts. It is shown that increased dispersion in the vectors of location and
scale parameters benefit, ex-ante, investors as does a decrease in the rank correlation coefficient between the location and
scale parameter vectors. Revealed preference comparative static results are identified for the location and scale vectors
of asset returns. For most issues addressed, we arrive at much stronger inferences when a safe asset is available.

The Median Voter Theory is an important theory in the neo-political economics. It can be applied to solve the collective choice
paradox and analyze the policy making for the citizenization of peasant workers. Adopting the method of factor analysis, this
paper makes an empirical study on peasant workers’ preference for citizenization. We find that there is a paradox of future
residence preference and self-identification in peasant workers. On this basis, peasant workers are divided into 5 subgroups,
and it is found that the median undecided peasant workers are the median voters. Based on the analysis of the median undecided
peasant worker’s complaints and appeals, it is proposed that the country should strengthen the vocational training system,
establish a social security system, expand the agricultural reform and promote educational reform to facilitate the citizenization
of peasant workers.

Group decision-making: Head-count versus intensity of preference 总被引:1,自引:0,他引:1
This paper puts forth a framework for reshaping the group decision-making process. The proposed framework extends from the usual one-issue-at-a-time decision-making to one that involves several related issues simultaneously. Weaknesses of the traditional majority voting mechanism are first identified, and then a different voting method that takes each individual voter's sentiment into account is discussed. Specifically, a decision-maker is asked to express his/her intensity of preference for the issues encountered. Three hierarchical structures—benefits, costs, and risks—are developed to evaluate the alternatives. Due to the nature of pairwise comparisons and synthesis, the proposed method is amenable to consensus building and has higher reliability and consistency. It can be used for candidate selection, e.g. governmental election, when a large population is involved. It is also effective for resource allocation and prioritization when a small group or business is concerned. We believe the proposed approach has potential for resolving deficiencies of the conventional voting mechanism, and can be applied to many real-world problems. Its implementation on the Internet is also discussed. 相似文献

We define an opportunity act as a mapping from an exogenously given objective state space to a set of lotteries over prizes, and consider preferences over opportunity acts. We allow the preferences to be possibly uncertainty averse. Our main theorem provides an axiomatization of the maxmin expected utility model. In the theorem we construct subjective states to complete the objective state space. As in E. Dekel et al. (Econometrica, in press), we obtain a unique subjective state space. We also allow for preference for flexibility in some of the subjective states and commitment in others. Journal of Economic Literature Classification Number: D81. 相似文献

多元化战略、经济绩效与资本结构——关于上市公司股权融资偏好解释 总被引:1,自引:0,他引:1
我国上市公司存在十分强烈的股权融资偏好,学术界一般将其原因归结为股权融资成本偏低。笔者研究则表明,融资成本因素并不能全部解释上市公司股权融资偏好。本文从企业多元化经营战略角度来剖析股权融资偏好。研究发现:企业多元化程度越低负债率越低,企业经济绩效越好;企业有动力降低负债率,采用股权融资。研究还发现,企业多元化战略已经构成融资决策的有效约束,股权融资偏好是上市公司的理性选择。 相似文献
