Nonlinear Drift And Stochastic Volatility: An Empirical Investigation Of Short-Term Interest Rate Models

In this article I provide new evidence on the role of nonlinear drift and stochastic volatility in interest rate modeling. I compare various model specifications for the short‐term interest rate using the data from five countries. I find that modeling the stochastic volatility in the short rate is far more important than specifying the shape of the drift function. The empirical support for nonlinear drift is weak with or without the stochastic volatility factor. Although a linear drift stochastic volatility model fits the international data well, I find that the level effect differs across countries.

Can Chinese Discuss Conflicts Openly? Field and Experimental Studies of Face Dynamics in China

Chinese people have been theorized to be particularly sensitive to social face and avoid direct discussion in conflict to promote interpersonal harmony. Social face has been used to explain the proclivity of East Asians to smooth over conflict. More research is needed to study social face empirically and its relationship with direct discussion and the processes by which social face has its impact. Results from a field interview study and an experiment conducted in China support theorizing that confirmation of face induces cooperative goals and open-mindedness. In contrast with common assumptions about Chinese organizations, direct discussion, compared to avoiding, strengthened relationships. Direct controversy, especially when face was confirmed, induced open-mindedness: Participants asked more questions, explored the opposing views, demonstrated more knowledge of the opposing arguments, and worked to integrate views. These results were interpreted as suggesting that Chinese people can discuss their conflicts directly and cooperatively when they are assured that their face is confirmed. Results have implications both for the general theory of cooperation and competition as well as our understanding of social face in China.

浅析90年代以来日本"流通革命"的原因

90年代以后日本流通业进入激烈变革时期，这种变革是二战以来的第二次流通革命。流通革命改变了日本流通体系和结构，流通企业和生产企业之间的重组日益流行，流通运营方式正在发生变化，因此流通革命将对日本经济产生重要影响。导致日本流通革命的原因很多，主要表现在价格破坏、定价体制改变、进口增加、购买方式变化、流通自由化、产销同盟和信息化等方面的原因。对这些原因及其背景的分析也反映了当今日本经济的概貌和面临的课题。     

The mean-variance investment problem in a constrained financial market

This paper extends the mean-variance analysis and the two-fund separation theorem to a market with some constraints, such as, the incompleteness, prohibition of short-selling, and partial information, with stochastic interest rate, and with stochastic volatility for risky assets. By maximizing a quadratic utility of terminal wealth, we show that the efficient frontier for the problem is a straight line in the mean-standard-deviation diagram. The quadratic utility function exhibits mean-variance efficiency. Our results apply to portfolios of claims in a single period, multiperiod, and continuous time.     

我国商业银行效率影响因素的实证研究

本文应用DEA方法得到的各商业银行的效率值作为因变量,构建Tobit回归模型,研究影响商业银行效率的主要因素,进而提出了提高我国商业银行效率水平和竞争力的相关建议。通过本文的研究,主要得出如下结论:产权结构、创新程度、总资产收益率指标和银行效率显著正相关,总资产规模、成本收入比、股权集中度与银行效率显著负相关,其中总资产收益率对银行效率的影响最大。     

政府公职人员经济人性边界界定与启示

政府公职人员是特殊经济人,并且从"经济人"角度、从历史性角度、从社会契约论角度、从初始社会分工及分工发展过程角度看,政府公职人员经济人性应有必要的边界。其经济人性发挥应符合作用空间的"非市场性"、经济人性范围的日趋"紧缩性"、经济人性目标满足渠道的"单一性"及较强的"社会性"这些内在规律。把握这些规律,可有效地建立针对政府公职人员的约束机制和非市场性的竞争机制,还可有效地促进民主发展,这对提升基本公共服务综合绩效及构建和谐社会都具有重要意义。     

后现代主义视野中的《白雪公主》

美国后现代主义作家唐纳德·巴塞尔姆在他的代表作<白雪公主>中成功地运用后现代主义创作手法即碎片式的拼贴、游戏式的戏仿和喜剧性的反讽彻底颠覆了经典的童话故事<白雪公主>,淋漓尽致地嘲讽了后现代社会平庸无聊的生活和精神的空虚与困惑,从而深刻揭示了后现代社会生活的反童话本质.
