交通基础设施影响下的物流业与区域经济的关联研究

鉴于通过物流业发展来解释我国区域经济发展这一主题存在的一些不足,文章在综述相关研究的基础上提出了二者之间存在非线性关系的观点。利用门槛回归模型,分别以铁路和高速公路路网密度作为交通基础设施门槛变量,证实了其在物流业提升区域经济发展水平这一运行机制上存在着非线性的调节作用。研究结果表明:2004-2013年间,铁路基础设施作为门槛,二者作用机制表现出了"由强转弱"的相关关系;高速公路基础设施作为门槛,二者作用机制表现出了显著的"倒U"型相关关系;在发展低水平阶段,铁路作为物流业的主要运输方式,对区域经济影响作用强大,随后作用逐渐减弱;公路在中等水平阶段明显高于低水平阶段;在其高水平发展阶段,促进作用略低于中等水平阶段。由于交通基础设施门槛效应的存在,文章建议应系统、动态地看待我国交通基础设施作用和因地制宜地制定物流业发展政策,推动区域经济的有效发展。

Is the future static or dynamic? The role of culture on escalation of commitment in new product development

Escalation of commitment in new product development has been studied extensively for the last four decades but the impact of culture on the escalation phenomenon remains largely unexplored. This study investigates how culture impacts the decision to escalate or deescalate commitment to new products. Americans are analytic thinkers whereas Chinese tend to be holistic thinkers. When it comes to decision making, analytic thinkers focus on field independent and abstract factors and believe that future is linear and static, whereas holistic thinkers focus more on contextual factors and believe that future is dynamic and nonlinear. Hence, Chinese are more likely to escalate their commitment relative to Americans on receiving a negative performance report in the new product development process. A lab experiment using weekend MBA students and managers was used to test this underlying hypothesis. The findings confirmed that analytical thinkers use fewer factors than holistic thinkers in making new product decisions, and that Chinese managers are more likely to escalate their commitment relative to American managers. The decision to escalate or de-escalate was moderated by perceived product innovativeness.     

Expiration‐day effects on individual stocks and the overall market: Evidence from Taiwan

On expiration days of the MSCI‐TW index futures, the Taiwan spot market is associated with abnormally large volume and high index volatility, along with mild index reversal. The effects concentrate only in the last five minutes of expiration days and appear to be strengthened by the adoption a call auction closing procedure by the Taiwan Stock Exchange. Individual index stocks show high volatility and strong tendency of price reversal, with large‐ and small‐cap stocks being affected more than the medium‐sized stocks. The highest‐weighted stocks exhibit excessive volume and volatility, which is disproportionate to the impact on all other index stocks, indicating that the expiration‐day effects may have been amplified by the attempt of price manipulation using large‐cap stocks. © 2009 Wiley Periodicals, Inc.

OFDM系统采样钟补偿算法及其FPGA实现

利用数字内插滤波器完成全数字域采样钟同步已广泛应用于OFDM数字接收机中.文中利用两个Farrow结构的内插滤波器,同时提高工作时钟对过采样信号进行数字域内插,完成接收端和发送端之间的采样时钟的完全匹配,并且根据硬件器件的特性和算法结构,逐级进行模块变量定点处理.基于实测数据的分析表明,该FPGA数字域采样钟补偿算法不仅有稳定的性能,而且其模块化设计也有利于更高阶算法或多通道系统的实现.

贵州省资本市场发展与区域经济增长关系的实证研究

运用V A R模型、脉冲响应函数、方差分解及格兰杰因果检验对贵州省资本市场发展与区域经济增长的相互关系进行了实证研究。结果显示:资本化率的提高加速了资本形成,改善了资源配置,促进了贵州经济增长,反之,则不成立;交易价值与经济增长之间不存在显著的相互影响关系;而交易价值与资本化率之间存在相互促进关系。在加快发展地方经济的同时,贵州省应采取有效措施,扶持有条件的工商企业尽快上市,以促进贵州经济的腾飞。     

会计准则与内部控制——基于委托代理关系和会计信息的研究

现代公司是由一系列委托代理关系组成的。从委托代理关系的角度看,会计准则和内部控制是为解决公司外部与内部委托代理问题而进行的制度安排。规范与优化会计信息、消除信息不对称是二者的共同目标。基于会计准则和内部控制在作用上的链接性和互动性,本文从委托代理关系和会计信息的角度对二者进行探讨,并在此基础上提出规范和优化会计信息的途径。     

Price discovery in the options markets: An application of put‐call parity

This study investigates the relative rate of price discovery in Taiwan between index futures and index options, proposing a put‐call parity (PCP) approach to recover the spot index embedded in the options premiums. The PCP approach offers the benefits of reducing model risk and alleviating the burden of volatility estimation. Consistent with the trading‐cost hypothesis, a dominant tendency is found for futures and a subordinate but non‐trivial price discovery from options. The relative weight of options price discovery is sensitive to the methodology employed as the means of inferring the option‐implicit spot price. The empirical evidence suggests that the information contained in the PCP‐implied spot encompasses that provided by the Black‐Scholes‐implied spot. © 2008 Wiley Periodicals, Inc.
