集团企业间关联交易的风险及防范措施浅析

随着市场经济的快速发展和进步,我国的经济实力不断增强,很多以集团公司为主要发展和经营形式的公司制企业应运而生。为适应市场竞争环境,集团企业下设若干子公司配合集团企业的经营活动,集团间关联交易频繁。集团间关联交易可以提高企业的资源配置效率、降低交易成本,对企业的发展产生一定的积极影响。论文主要针对集团企业间交易的灵活性和可操作性以及交易定价、资金拆借、税务筹划等方面进行深入分析,并在分析的基础上阐述集团企业间关联交易风险的防范措施,使关联交易不仅能够满足企业长期发展战略的需要,又尽可能地避免关联交易所带来的不利影响。     

论高校学生干部开展团体辅导的必要性

近年来,新生入学教育形式呈现多元化趋势,而其主旨多围绕于帮助新生快速适应大学新环境,找准定位,迅速确立目标。健康的心理是当代大学生成才的必备条件,良好的心理健康氛围往往更有利于学生在大学生涯中更好的学习生活。而作为大学生思想政治教育的关键一环,高校学生干部心理健康教育在新生教育中往往处于失语状态。本文以团体辅导为引,讨论高校学生干部开展团体辅导的必要性。

团体规模、动态激励和社会链接对团体贷款影响的实证分析

本文通过实证分析,考察了团体规模、动态激励、社会链接三个重要因素对团体贷款的影响。结果表明:团体规模对团体贷款效率的影响并不显著,较大的规模更易诱发道德风险,但能降低团体总体风险;动态激励对团体贷款的有效运行具有重要作用;社会链接对团体贷款效率具有重要影响,强的社会链接可以诱致更高但不够稳定的还款意愿。     

Generalized beta distributions for describing and analysing intraday stock market data: testing the U-shape pattern

There is an impressive body of empirical evidence which indicates the existence of an intraday U-shaped curve in stock prices. In an effort to shed additional light on the U-shaped curve a new procedure for U-shape testing is introduced. From careful analysis of intraday data it is observed that minimum or maximum stock prices can occur several times during the day. Here, attention is focused on the first time during the day that the maximum or minimum stock price occurred. Because of the importance of the first time during the day that the maximum or minimum stock price occurred, an attempt is made to model these two characteristics with probability distributions. The objective of this study is to use a generalized beta distribution to examine the intradaily behaviour of stocks, using closing stock prices for each one-minute interval, using data from Athens Stock Exchange (ASE). This generalized beta distribution has not been used before to model U-shaped behaviour. The results are consistent with the intraday U-shaped curves, i.e. the time to first maximum (or minimum) stock prices follows a U-shaped pattern. In addition, some potential applications of the generalized beta distribution are discussed and exemplified by analysing the relationship between herd behaviour and U-shaped.     

ExpertLens: A system for eliciting opinions from a large pool of non-collocated experts with diverse knowledge

The complexity of policy decision-making raises the need to elicit opinions from large and heterogeneous groups of stakeholders with broad and diverse sets of expertise. Existing options for elicitation include small face-to-face panels of experts by using the Nominal Group Technique (NGT), large Delphi panels whose members do not interact with each other face-to-face, and crowdsourcing, which involves an open call for input issued to a large community of people. In an attempt to close the gap between the practical needs of policy makers and the methodological challenges associated with eliciting opinions of large, diverse, and distributed groups, we have developed a new online elicitation system and methodology called ExpertLens. By optimizing the direct interactions of NGT with the larger number of Delphi participants and the wisdom of “selected crowds,” our approach is designed to save on the costs associated with traditional expert panels, while increasing accuracy in elicitation by reducing the potential for group process losses that can occur in large, diverse, and non-collocated panels whose members interact via asynchronous online discussion boards. The ExpertLens approach is iterative, does not require participants to develop consensus, and determines what the group “thinks” by statistically analyzing data collected in all rounds of the elicitation. This paper describes the ExpertLens system and methodology, briefly discusses recent ExpertLens trials, provides conceptual arguments for why it is an appropriate model for eliciting expert opinions, illustrates its main components and analytics by using an infrastructure investment example, and discusses a research agenda for testing the underlying tenets of the ExpertLens approach.     

董事会特征、高管激励与集团绩效——来自中国上市集团公司的经验证据

作为一个多法人联合体,企业集团的治理与单体企业不同.通过实证研究发现,中国上市集团公司的董事会规模并没有对集团绩效产生积极效应,独立董事也未能有效发挥监管职能;董事长与总经理两职合一与集团公司绩效负相关;合理有效的报酬制度与公平透明的股权激励环境有助于集团公司绩效的提高,而股权激励制度有待进一步完善.

Bioeconomics of some nonhuman and human societies: new institutional economics approach

New institutional economics (NIE) has been very successful in explaining the role of institutions such as the firm, money, and contract law in facilitating production and exchange in human societies. In this paper, I will show that the NIE approach, which so far has been used by economists to analyze institutions and organizations in human society, including the ethnically homogeneous middleman groups, can also be extended to explain the high degree of cooperation and coordination of activities of honeybees, ants, and schooling fish. In addition, the paper emphasize the importance of identity in nonhuman and human societies in eliciting cooperation and in detecting cheaters or fakers. This paper thus contribute to the integration/consilience of economics and biology by providing a more unified view of aspects of the bioeconomics of nonhuman and human societies.
