中英电信"双寡头垄断"模式比较研究

中国电信南北分拆以后,将在固定电话和移动电话两个业务领域形成新一轮"双寡头垄断"竞争格局.英国是率先实行"双寡头垄断"作为过度,最终走向电信全面开放竞争的典范.中国电信业在1994～1999年第一阶段改革中,曾试图仿效"英国模式",构建中国电信和中国联通的"双寡头垄断",最终以失败告终.在中国即将形成新一轮"双寡头垄断"竞争格局之时,我们有必要通过对英国电信改革的理论背景、具体实施过程、取得的成就的回顾,探求英国"双寡头垄断"成功的奥秘,并为中国新一轮电信重组所借鉴,提升中国的电信业国际竞争力,更好地应对WTO的挑战.     

"净利+利息+折旧"抑或"净利+税后利息+折旧"?——对会计资格考试辅导教材中经营现金净流量计量方法的商榷

计算项目净现值(NPV)等投资决策指标时,现金流量与折现率应具有匹配关系。从两者的匹配关系看,全国会计专业技术资格考试辅导教材《财务管理》一书中的经营现金净流量(NCF)计量公式有欠妥当。因为以项目的加权平均资本成本(WACC)作为折现率时,与之相应的NCF的计量方法不应是教材中的“净利 利息 折旧”,而应该是“净利 税后利息 折旧”,或者是“息税前利润(1-所得税率) 折旧”。     

转型时期弱势群体的社会救助

在社会保障制度的建立和发展过程中,社会救助最早建立.但是,现代的社会救助与早期的社会救助有本质上的区别.转型时期弱势群体的社会救助,是建立在一定的法规之上,具有社会性、制度性和强制性的社会保障制度.     

影响人民币实际汇率长期趋势的因素研究

本文对人民币实际汇率的长期变动趋势进行了实证研究。通过协整模型构建了实际汇率与劳动生产率、政府消费和贸易条件之间长期的均衡关系，并通过误差修正模型考察了实际汇率短期内的动态调整过程。结果表明，无论在短期还是长期，生产率的变动对人民币实际汇率的变动都起着最重要的作用，但是对实际汇率的变动方向与巴一萨效应预测的相反。这可能是因为中国的经济发展阶段不适用其假设，劳动力的无限供给、政府消费和贸易条件等其他因素亦影响着人民币实际汇率的变动趋势，说明即使是在长期内，巴一萨效应的假设也不能成立。政府能够通过财政支出来影响实际汇率短期波动和长期变动趋势，从而影响我国产品在国际上的价格竞争优势。

The effects of group decision-making process and problem-situation complexity on implementation attempts

The effects of group problem-solving method and problem-situation complexity on attempts at implementing group solutions were investigated in a laboratory-field setting. Group members were supervisory nurses from various organizations, who were randomly assigned to three groups in a balanced research design which included three group decision-making processes and three levels of problem-situation complexity in implementation. The dependent variable was the number of attempts at implementing group-derived solutions in home organizations. The results showed that structure in group decision-making processes led to increased rates of implementation attempts at all levels of problem-situation complexity. There was a significant complexity-by-process interaction effect among the decision-making processes, which supports the conclusion that the type of group decision-making process and the problem-situation complexity should be considered in order to optimize the number of implementation attempts.g     

Critical factors in computing externalities for electricity resources

The New York State Environmental Externalities Cost Study and computerized externality model (EXMOD) are used to examine the specification of methods design and application factors in the computation of electricity externalities. We report the sensitivity of externality estimates with alternative specifications for 15 different factors in the analysis, including the selection of facility type, site, and operating characteristics; air emission assumptions and air modeling procedures; dose-response assumptions; economic valuation assumptions; and other modeling procedures and assumptions. Many of the factors that most influence externality computations can be well specified in the analysis, such as the facility type, age, characteristics, emission rates, whether there is SO₂ trading, and the inclusion of long range impacts. Most significant among the factors for which there remains significant scientific uncertainty are the selection and application of air dispersion models, selection of air pollution thresholds for health impacts, reduced life span risks associated with ozone exposure and with long-term exposure to PM₁₀, values for CO₂ damages, and the value to be applied to increased risks of reduced life span for individuals age 65 or older.     

中国股市现金股利悖论研究

现金股利悖论指现金股利增加或降低都可能增加代理成本,从而损害中小投资者利益.现金股利能保护中小投资者利益是国内外流行的观点.文章在考虑我国存在高比例非流通股的事实下,从代理成本角度对我国现金股利与中小投资者利益关系进行了系统的理论分析,提出了"现金股利悖论",并得出三条推论:股权越集中的公司,现金股利支付率越高;国有股股东比法人股股东更偏好现金股利;现金股利支付极不稳定.但对三条推论的检验结果表明,在未考虑其他影响因素时国有股股东与法人股股东对现金股利的偏好并无显著差别.增加现金股利的一刀切的做法并不可取.要解决现金股利的两难处境,前提是股票全流通.
