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.

The Federal Energy Regulatory Commission's Order 636 fundamentally altered the regulatory and operational environment of the natural gas industry in 1992, as the culmination of several directives aimed at relaxing regulation and fostering competition. We hypothesize that gas pipeline firms subsequently changed their operational and financial behavior in ways consistent with reduced balkanization, increased competition, and reduced expense preference behavior. Our results indicate that these firms have become more homogeneous financially but less so operationally. We find evidence that the marginal profitability of various pipeline activities has responded more to financial market conditions than to the regulatory environment. 相似文献

本文采用Williamson的思路,建立了资产专用性与交易成本、生产成本因素在内的综合交易成本分析模型。分析发现,相对于债务融资而言,股权融资有利于避免按市场规则强行清算带来的专用性资产价值损失,运用包络定理证明专用性程度高的资产具有削减生产成本的作用,专用性程度高的资产以股权融资为佳。 相似文献

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

如何提高金融服务实体经济的结构性调节功能并促进企业有序运营与健康发展是金融供给侧结构性改革的重要目标。利率市场化改革作为金融领域最重要的改革之一,其在微观层面如何影响实体经济运行引起了高度关注。本文首先从理论上诠释了利率市场化通过缓解融资约束、抑制金融化进而降低企业营运风险的逻辑关系。为识别利率市场化与企业营运风险之间的因果效应,本文以中国人民银行2004年10月取消金融机构贷款利率上限和2013年7月取消金融机构贷款利率下限为外生冲击,基于融资约束差异构造准自然实验为上述理论推断提供经验证据。特别地,利率市场化每增加1单位标准差,企业营运风险平均约下降样本标准差的2.39%。异质性分析表明,利率市场化对企业营运风险的抑制效应在融资约束程度较高、行业竞争程度较高、投资机会较多的企业中尤为明显。本文研究对于进一步优化资源配置效率、实现金融与实体经济高质量发展具有一定参考意义。 相似文献

不同的银行信贷技术对中小企业具有不同的影响,银行业的逐渐开放,竞争的日益激烈,银行间并购逐年增加,银行业竞争结构的变化严重影响着中小企业融资。随着中国经济与世界经济接轨程度的加大,《新巴塞尔协议》的逐步推行,将不同程度影响银行业竞争结构及中小企业的信贷供给。因此,在制定相关政策时,要充分考虑金融政策的传导机制,不仅考虑其对金融体系及金融中介竞争结构的影响,而且还要考虑到对中小企业融资的间接影响。 相似文献
