农村居民幸福指数研究及路径选择——以山东省为例

立足"中国梦",按照社会主义新农村建设和2013年中央一号文件的内涵与要求,把握我国新农村建设的原则、目标和重点内容,以山东省的济南、青岛和菏泽三个农村地区为中心进行考察,基于主成分分析法研究三个地区的幸福指数,研究发现:提高农村居民幸福感的四条路径为增加农民收入、加快经济合理调整、注重人文环境、自然环境建设和提高政府信用水平。     

The Beauty Contest and Short‐Term Trading

Short‐termism need not breed informational price inefficiency even when generating beauty contests. We demonstrate this claim in a two‐period market with persistent liquidity trading and risk‐averse, privately informed, short‐term investors and find that prices reflect average expectations about fundamentals and liquidity trading. Informed investors engage in “retrospective” learning to reassess inferences (about fundamentals) made during the trading game's early stages. This behavior introduces strategic complementarities in the use of information and can yield two stable equilibria that can be ranked in terms of liquidity, volatility, and informational efficiency. We derive implications that explain market anomalies as well as empirical regularities.     

谈加权平均资本成本法在个别项目评估中的应用

现实当中,由于企业暂时无需纳税,资本结构当中债务融资比例不固定,个别项目与企业整体资产风险差异较大等因素的存在,使得直接运用加权平均资本成本(WACC)对个别项目进行价值评估和资本预算分析容易产生较大的偏差甚至可能导致错误的决策,因此,对具体项目的风险系数进行调整以正确使用WACC方法进行项目价值评估,从而使得出的结论更为可靠有效,有助于企业更好地进行项目筹资和投资决策。     

技术指标可以战胜市场吗?——兼论中国证券市场弱式有效性的变化

文章以上证综指的历史数据为样本,研究了证券技术分析中常用的均线指标(MA)和随机指标(KDJ)的获利能力及其变化。结果表明:均线指标能获得显著超越市场平均水平的收益,而随机指标随着市场发展获利能力逐步减弱,这表明我国证券市场趋于更加有效,但仍未达到弱式有效。此外,研究发现,基于技术指标的多头和空头收益具有相同分布,但实行涨跌停板制度后,收益分布发生了显著变化。     

数学在建筑监察领域的运用

对于在建建筑的规划管控,是一个城市规划管理局的重要职能,由于在建建筑众多,尤其对于一些大型城市,对于在建建筑的规划管控主要是从建筑物的尺寸角度来进行的,包括是否超宽、超高等。如何引入计算机数学思想,构建一个在建建筑的智能化规划监察管控系统,并杜绝人情因素,成为提升规划监察工作效率和质量,体现科学发展观的重要技术手段。     

The Effectiveness of Technical Trading for Arab Stocks

In this paper, we examine the profitability of technical analysis for a cross section of individual Arab stocks. Our analysis, undertaken from the perspective of an Islamic investor, reveals that technical trading rules do not yield economically or statistically significant returns. While our results uncover some scant statistical evidence of technical trading rule profitability, risk adjusting the returns weakens the evidence in favor of predictability. Furthermore, break-even transaction costs do not exceed estimated transaction costs or bid-ask spreads in the markets examined.     

所得税申报中资产时间性差异的调整方法比较

在所得税申报中,资产时间性差异的纳税调整要涉及几个纳税年度,并且一个正常生产经营企业的资产往往处在动态过程中。每年有新增资产,也有出售、报废、到期的资产,要准确无误地对其进行纳税调整,是所得税申报中的一个常见问题也是难点问题。文章通过对所得税申报中资产时间性差异调整的两种方法的比较,确定一种较为简便可行的方法。     

论孙中山民生思想的中国特色

孙中山先生解决民生问题的手段具有典型的中国特色,一是平均地权,一是节制资本,这是在其他任何国家都未曾有过的手段。孙中山先生认定只要实施这两个办法就可以解决中国的民生问题。在对孙中山先生民生思想的研究中,我们可以获知,这位辛亥革命的先驱者当年明确地认识到,历史的重心是社会问题,社会问题的重心是生存问题,生存问题就是民生问题,民生问题不是政治问题,而是经济问题,是社会的存在与发展必须给予解决的经济问题。     

Heterogeneous treatment effects and mechanisms in information-based environmental policies: Evidence from a large-scale field experiment

Policymakers often rely on non-pecuniary, information-based programs to achieve social objectives. Using data from a water conservation information campaign implemented as a randomized controlled trial, we estimate heterogeneous household responses. Understanding such heterogeneity is important for improving the cost-effectiveness of non-pecuniary programs, extending them to other populations and probing the mechanisms through which the treatment effects arise. We find little evidence of heterogeneous responses to purely technical information or to traditional conservation messages that combine technical information and moral suasion. In contrast, norm-based messages that combine technical information, moral suasion and social comparisons exhibit strong heterogeneity: households that are wealthier, owner-occupied and use more water are more responsive. These subgroups tend to be least responsive to pecuniary incentives. We find no evidence that any subgroup increases their water use in response to the messages. By targeting the messages to subgroups known to be most responsive, program costs could be reduced by over 50% with only a 20% reduction in the treatment effect. Combining theory and data, we also shed light on the mechanisms through which the treatment effects arise, which has implications for program design and future research on the program's welfare effects.     

略论新中国建国初期的城乡物资交流

城乡物资交流的组织和开展,使城乡关系逐渐恢复正常,扩大了广大农村农副产品和土特产品的销路,提高了农民群众的购买力;促进了城市工商业的发展和趋向繁荣,增加了国家的税收,减少了财政上的困难,物价更稳定,对于建国初期国民经济的恢复和发展起了积极重要的作用。
