土地一级开发中储备土地出让价格影响研究——以武汉市后湖地区为例

研究目的为了解武汉市后湖地区土地一级开发中基础设施投入对土地产出效益的影响,为政府的投资决策提供参考。研究方法为层次分析法和经济学研究方法。研究结果为（1）土地储备中道路设施投入对土地价格的影响最显著,权重系数为0．211;（2）随着道路设施投入的增加,土地产出效益呈先递增后递减的趋势,其影响路径符合边际报酬递减规律。研究结论为在土地一级开发中应注重道路等基础设施的投入,同时要遵循边际报酬递减规律,减少投入的盲目性,避免粗放的经营发展方式,进而控制土地储备成本,提高土地的投入产出效率。     

以提高农民收入水平为抓手建设和谐美丽新云南

农民收入问题事关国民经济协调发展和社会和谐稳定。本文在分析云南农民收入水平低、城乡收入差距大、地区不平衡突出、贫困人口多,从而制约着云南科学发展、和谐发展与跨越发展基础上,提出建设和谐美丽新云南应以提高农民收入水平为抓手,发挥云南比较优势、统筹城乡协调发展、依靠科技进步和增强农民增收本领等举措促进农民增收和保持农民收入持续较快增长。     

保障性住房低碳管理的体制创新研究

在分析了低碳社区和保障性住房发展所面临的困境的基础上,提出了将"低碳生活方式"的约束机制和"保障性住房"的奖励机制相结合,建立低碳约束下的保障性住房管理创新体制,并在制度经济学和行为心理学相关研究的基础上给出了这一管理体制的普遍性框架设计,然后从实施角度分析了该管理体制的合理性和可操作性。     

公共产品缺乏是造成住房价格偏高的重要原因

近年来,我国住房价格不断上涨,但房价仍在消费者承受范围内;房地产开发企业并未出现普遍的暴利行为;居民人均购房与建房支出占家庭收入的比重也没有明显的增加。由于公共产品不足,居民家庭教育和医疗支出所占的比重迅速提高,消费者对未来收入和支出的不确定性预期增强,购房能力相对下降。消费者越来越不敢花钱,也就越来越觉得住房价格高,因此,公共产品缺乏是造成住房价格偏高的重要原因。     

Subjectivity in fair-value estimates,audit quality,and informativeness of other comprehensive income

This study empirically examines whether difference in audit quality is reflected in the pricing of other comprehensive income (OCI). Specifically, we first investigate whether OCI measures of Big 4 clients are more value-relevant than those of non-Big 4 clients. Considering different degrees of subjective management judgment involved in the OCI reporting process, we then explore whether the differential valuation effect of OCI between Big 4 and non-Big 4 clients is more pronounced for more subjective OCI components (e.g., minimum pension liability and foreign currency-translation adjustment) than a less subjective component (e.g., marketable securities adjustment). We predict that the aggregate OCI of a Big 4 client is more value-relevant than that of a non-Big 4 client. We also hypothesize that the differential valuation effect between Big 4 and non-Big 4 clients can be attributed to the amount of subjective assumption and judgment required in estimating OCI. Consistent with our predictions, we find that aggregate OCI audited by a Big 4 auditor has incremental information content over earnings, compared to OCI audited by a non-Big 4 auditor. More interestingly, our results also show that the differential valuation effect between Big 4 and non-Big 4 clients is stronger for OCI components of a more subjective nature. Our results are robust even after controlling for self-selection bias, the potential effect of the financial crisis, and other related effects.     

融资约束抑或过度投资——中国上市企业投资—现金流敏感度的经验证据

本文以中国上市企业为分析样本,通过检验现金持有量对投资—现金流敏感度的影响,考察企业中的融资约束和代理冲突。结果显示,融资约束与过度投资导致企业投资支出与内部现金流密切相关。民营企业、大规模地方国有企业中存在过度投资,所持有的现金具有明显的壕沟效应、进一步提高投资—现金流敏感度。而中、小规模国有企业面临的融资约束比较突出,为了抵御外部融资约束,持有现金充当对冲工具、降低投资—现金流敏感度。     

跨境资金流动中的套利模式：一起境外投资案例

在当前国际国内经济形势下,境内外融资成本存在较大差异,部分银行、企业通过资金曲线运作从中获取短期双赢,但在宏观层面上却进一步加大了跨境资金流动的波动性,不利于国际收支平衡,最终会影响到微观经济效率。本文选取了一个境外投资案例,对其资金曲线运作手法、套利模式等进行了深入剖析,进而对当前合法合规套利资金的监管方式进行了延伸性探讨。     

持久性收入对中国农民消费影响分析

运用弗里德曼的持久性收入假说分析我国农民的消费问题,并利用计量经济学的方法对中国历年农民消费统计数据进行分析,得出“持久性收入及持久性收入的边际消费倾向对我国现阶段农民消费支出影响较大”的结论,并从增加持久性收入和提高持久性收入的边际消费倾向两个方面就增加农民消费提出政策建议。     

Income Polarization of the U.S. Working Class: An Institutionalist View

We provide an institutional insight into the trend of income polarization within the U.S. working class. In contrast to the previous industrial waves, the current and ongoing industrial revolution is characterized by the replacement of “creative destruction” with jobless growth. Instead of replacing the lost jobs with new ones, new disruptive technologies eliminate more jobs in traditional labor and capital-intensive sectors than create jobs in new idea-intensive sectors. By examining the relationship between the income share of the bottom 50 percent, the middle 40 percent, and the top 10 percent and technological progress, we obtain robust econometric results. According to our results, the income polarization among U.S. workers can be associated with the shift of R&D activities from the public to the corporate sector. The concentration of innovations by corporate capital limits the power of society to reduce inequality and to provide greater social stability through “the incredible productivity” of technological progress.     

Money, Sex and Happiness: An Empirical Study

The links between income, sexual behavior and reported happiness are studied using recent data on a sample of 16,000 adult Americans. The paper finds that sexual activity enters strongly positively in happiness equations. Higher income does not buy more sex or more sexual partners. Married people have more sex than those who are single, divorced, widowed or separated. The happiness‐maximizing number of sexual partners in the previous year is calculated to be 1. Highly educated females tend to have fewer sexual partners. Homosexuality has no statistically significant effect on happiness.
