Summary. The requirement that a voting procedure be immune to the strategic withdrawal of a candidate for election can be formalized
in different ways. Dutta, Jackson, and Le Breton (Econometrica, 2001) have recently shown that two formalizations of this candidate stability property are incompatible with some other
desirable properties of voting procedures. This article shows that Grether and Plott's nonbinary generalization of Arrow's
Theorem can be used to provide simple proofs of two of their impossibility theorems.

社区商业文化产生于社区商业细致入微的服务及相对稳定的服务对象两者之间积极互动的过程。社区商业经营活动的过程就是社区商业文化形成的过程。质优价宜的商品、全面细致的服务、社区活动的参与和促销宣传活动的结合,强化了社区网点与社区居民之间的亲和关系。充分发挥社区商业文化吸引消费、引导消费的价值,必须从战略的高度对待选址、服务配套、人员配备、参与社区建设等经营管理的问题。 相似文献

多媒体高职英语教学的几点思考 总被引:1,自引:0,他引:1
王建苗 《山西经济管理干部学院学报》2007,15(1):99-101
多媒体技术辅助于高职英语教学有很多优越性,但在应用过程中存在教师对多媒体教学理解不深入、教学软件不足等问题。要使多媒体高职英语课堂教学达到最优化,必须提高教师对多媒体英语教学的科学认识,加强现代教育技术学习,提高制作教学课件的能力,加强传统教学与多媒体教学的整合。 相似文献

We model the Danish market for mortgage backed securities with a two-factor interest rate model and use a stochastic programming approach to analyse how an individual home-owner should initially compose and subsequently readjust his mortgage in an optimal way. Results show that the 'rules of thumb' used by financial institutions are reasonable, although best suited for more aggressive mortgagors, for whom the delivery option is of some value. More risk-averse investors should also re-adjust frequently, but use more diversified portfolios. Results are insensitive to whether a one- or two-factor model is used, provided the former is suitably calibrated. 相似文献

Willingness to take on risk is influenced by the presence of fair and unfair background risks for decision makers who are risk vulnerable as defined by Gollier and Pratt [1996], for these decision makers are more risk averse when they possess such an uninsurable background risk. We present an alternative derivation of the index of local vulnerability based on Diamond and Stiglitz [1974] compensated increases in risk, such that risk aversion increases with the introduction of any small fair background risk if and only if the index of local vulnerability is positive. We establish that the increase in risk aversion is greater for those who are more vulnerable as measured by the index of local vulnerability. 相似文献

In this paper, we examine a trader's order choice between market and limit orders using a sample of orders submitted through NYSE SuperDot. We find that traders place more limit orders relative to market orders when: (1) the spread is large, (2) the order size is large, and (3) they expect high transitory price volatility. A rise in informational volatility appears neither to increase nor decrease the placement of limit orders. We also find that a rise in lagged price volatility decreases the size of spread, which is driven by the increase in the placement of limit orders. 相似文献

Utilizing Printed Media to Understand Desired Leadership Attributes in the People's Republic of China 总被引:1,自引:0,他引:1
Using news media as a reliable source, we content analyzed stories on business leaders in two major official Chinese newspapers in three different time periods over the past 20 years. Results show that the reform has brought an increase in stories of business leaders, and in coverage of the desirable leadership attributes relating to Confucian virtues, communist ideologies, and modern management philophies. The results suggest that, by publicizing and adorning specific leaders in both government and business sectors in the official media, the government reinforces the traditional values that are consistent with communist ideologies, and at the same time, it also introduces Western management values to suit the current needs of the society. The results of our study echo the findings of empirical studies on Chinese values that used data collected using other methods. We therefore encourage future research to use the printed media as a potentially valuable source of data for tracking changes in social phenomena in a society over time. 相似文献

西部新型工业化道路的特殊性及战略选择 总被引:1,自引:0,他引:1
西部目前正处于工业化初期向中期过渡期,加深工业化仍然是一项艰巨的历史性任务。由于西部工业基础薄弱,结构不尽合理,且信息化、现代化程度低,与东部发达地区相比,西部新型工业化道路具有特殊性。因此,优化西部地区产业结构、提高现代化新技术水平,用资源引进资本以及推动农业工业化等,是西部新型工业化的必由之路。 相似文献

论国企改革中的不可信威胁、监督制衡与路径选择 总被引:1,自引:0,他引:1
虽然大多数国有企业都进行了公司制改造,但是效益并没有得到明显的改善.一方面,所有公司治理机制的有效性最终都取决于在市场竞争中失败成为一个可信威胁,而对于许多国有企业来说,在政府"父爱"的关怀下,这种威胁是不可信的,这使得国有企业经营者没有压力进行创新,得过且过,效益低下是自然的结果.另一方面,国有企业的投资者、债权人只有弱的动力去监督国有企业,国有企业也并没有建立起内部的制衡机制,这使得国有企业的"内部人控制"现象仍很突出,经营者可以"任我行".我们认为国有企业低效与其独特的产权制度密不可分,国有资产分步骤、有条理、有规则地退出竞争性领域,这是改革的关键.引进机构投资者,加强市场监督,加大剩余索取权在企业从业人员中的分享程度也是促进国有企业公司制改革,提高国有企业运营效率必不可少的环节. 相似文献
