国际货币体系改革——金融危机后的思考

美国次贷危机引发的全球金融危机,使现行国际货币体系—牙买加体系的缺陷进一步暴露出来:美元本位制放纵了美国的过度消费,国际资本流动缺乏监管以及不稳定的汇率体系加剧了危机蔓延。虽然对国际货币体系的改革面临美元霸权、改革成本高等方面的阻碍,但改革现行的IMF以及扩展国际救助范围,加强金融监管力度已然成为改革方向。     

The Information Content of Model‐Free Implied Volatility

This study examines the information content of model‐free implied volatility (MFIV) estimates with respect to the options and futures markets in Hong Kong. In this study, the volatility forecasting performance of MFIV is compared, using different prediction horizons, to IV estimates based on Black's futures option pricing model (BIV) and time‐series forecasts based on historical volatility (TS‐HV). The results show that the BIV prediction is unbiased for different horizon forecasts. MFIV outperforms TS‐HV forecasts and, most importantly, BIV subsumes the information content of both MFIV and TS‐HV forecasts. The results are largely maintained for next‐day forecasts but the forecasting quality of the two IV measures declines as expiration day approaches. The information contents of MFIV and TS‐HV forecasts are complementary. © 2012 Wiley Periodicals, Inc. Jrl Fut Mark 32:792‐806, 2012     

Adolescent Evaluations of Brand Extensions: The Influence of Reference Group

This study examines the reference group effect on adolescent evaluations of brand extension. Three factors are important to this process: the product fit between parent and extension category (similar vs. dissimilar), the consumption type of the extension product (public vs. private), and the parent brand image (prestige‐oriented vs. functional‐oriented). An experiment with 217 teenagers generally supports the hypotheses. Results suggest that adolescents are willing to pay a higher price premium to publicly consumed brand extension product than a privately consumed. In addition, the level of category similarity enhances the consumption type effect. Managerial implications on brand extension strategy in adolescent's market are discussed.     

一种新型有源滤波器谐波电流检测方法研究

文章首先介绍了独立电源系统的特点,并阐述了独立电源系统有源滤波器谐波和无功电流的补偿原理。而后,根据独立电源系统的特点,提出了一种新型的谐波电流检测方法,通过与传统的瞬时无功功率理论和快速傅里叶变换提取谐波方法相比,该方法计算简单、准确度好、实现方便,具有较大的优越性,并在实际的有源滤波器装置中得到了较好的应用,表明该方法是正确和有效的。
