低利率时期的货币政策效果——台湾地区及日本经验

日本央行在最近一波的景气衰退中被指为货币政策操作不佳,因其似乎只专注降低利率而忽视其它传递管道.货币政策在景气差的低利率时期是否能有效果是本文所要探讨的.台湾地区货币主管部门在上一波不景气中也不断以调降利率作为因应,因此本文利用VAR(向量自我回归)模型分别针对台湾地区及日本这两段经济不景气的低利率时期进行讨论分析.根据冲击反应分析显示,不论是台湾地区或日本在观察样本期间都得到货币政策无效的结论,其中台湾地区可能存在"投资陷阱";日本则发现存在"流动性陷阱".     

A study of virtual land trade between China and ASEAN based on material flow analysis model

In this paper,based on the material flux analysis model（MFA） and its corresponding theories and algorithms of ＂virtual land＂ virtual land contents of five primary agricultural products are calculated and＂Virtual land trade＂hidden in those imported and exported products are also obtained through analyzing the primary agricultural product trade between China and ASEAN. In the process of calculationl following the thought of Changing agricultural products to ＂Virtual land trade＂land content, trade condition and spatiai distribution of agricultural products Were integratedly considered. indicate that China exported 73;057 km^2 of virtual land area to ASEAN by tea, vegetables; maize and grain, ASEAN exported： 57.332 km^2 to China by natural rubber from 2002 to 2005. It obvious; that china has lost 15,725 km^2 arable land through agricultural product trade, Additionally, in order to process： of calculation Virtual land trade, Thailand taker as an example to analyze its international trade of rice and Wheat from 1991 to 2005 and Calculate their ＂Virtual land trade＂ 2001 through 2005. According to and calculation, it is not difficult to conclude that ＂Virtual land trade＂ very important and could be used for China to guide agricultural export or import Structure and maintain Sustainable use of land resources.

关于我国货币需求与实际货币缺口的经验研究——基于二阶局部调整模型的分析

本文利用二阶局部调整模型对我国的货币需求函数进行了定量估计.估计结果表明,实际产出、名义利率、通货膨胀率、股票市价总值以及货币替代率均对我国的狭义和广义货币需求产生了显著的影响.分析表明,我国近年来的利率和汇率政策仍然是以稳定通货膨胀为主要任务的;通过利率调整或者人民币升值等货币政策改善我国货币供求状况的过程中,应进一步关注各宏观经济变量对货币需求的影响动态.     

中国城镇居民的劳动供给行为——倒S型劳动供给曲线在中国城镇劳动力市场上的实证检验

依据2002年中国家庭收入项目(CHIP)数据,本文应用微观经济计量方法估计了城镇居民的就业方程和工作时间方程。研究结果表明,随着教育年限的增加,个体就业概率不断增加;随着家庭其他收入的增加,个体就业倾向逐渐降低,工作时间逐渐减少;随着家庭人口数的增加,就业个体的工作时间逐渐增加。低收入群体女性和男性工作时间的工资弹性分别为-0.3237和-0.3167,而女性中高收入群体工作时间的工资弹性为0.1429,说明倒S型劳动供给曲线在2002年中国城镇劳动力市场是存在的。因此,政府部门应结合经济发展水平适时地提高最低工资标准,完善社会保障制度,同时加大对低收入群体教育和培训投入力度,促进低收入群体社会福利水平的改善。     

Alignment or entrenchment? Corporate governance and cash holdings in growing firms

This study contends that the association between corporate cash holdings and corporate governance is subject to the investment environments that firms face. For example, firms with an abundance of investment opportunities have a strong incentive to hold cash in order to maintain their competitive positions. Shareholders accept high levels of cash holdings in such growing firms if corporate governance can protect their interests. This study examines the effects of corporate governance on cash holdings for a sample of high-tech firms. The results show that CEO ownership, the directorship of venture capitalists (VCs), and independent directors play critical roles in corporate cash policy. In addition, the boards are more effective when the firms' CEOs are also their founders or when VCs hold a large stake of company shares. The effects of corporate governance are more significant in younger firms while the effects of firm-specific economic variables are more significant in older firms in the sample.

激励、监督与经销商依从：依赖结构的调节作用

文章以代理理论为基础,实证分析激励和监督对经销商依从的影响及依赖结构的调节作用。研究发现：激励会促进经销商依从,而监督则会抑制经销商依从;相互依赖强度会削弱监督对经销商依从的负向影响,但对激励与经销商依从间的关系没有显著影响;经销商相对依赖会增强激励对经销商依从的正向影响,但对监督与经销商依从间的关系没有显著影响。文章最后对研究发现进行讨论,并提出管理建议和未来研究的方向。
