This study sets out to investigate trading in Standard and Poor's Depository Receipt Trust Series I (SPDR) options and the impact on the price‐discovery process of SPDRs. The empirical results reveal a significant rise in liquidity within the SPDR market following the introduction of SPDR options. Furthermore, the results also show that the introduction of SPDR options has led to a significant improvement in the information share of SPDRs, and that the contribution of SPDRs to price discovery has become very close to that of E‐mini index futures. These findings imply that developments in the derivatives market can lead to improvements in market quality, including the level of liquidity and price discovery of the underlying securities. © 2011 Wiley Periodicals, Inc.

自省是儒家道德实践的重要方法。目前有关自省的研究侧重于道德领域,学界对自省的存在论这一层面给予的关注比较少,因而通过对自省的存在论这一层面的发掘,可以从理论上澄清自省可以更好地认识你自己,阐明自省中蕴含着二个层面的存在形态即意向性的自我意识和非意向性的自身意识。在哲学认识领域内,研究自省可以克服盲目性,提高自觉性。在实践上,重建对网络的自由关系乃是整个中华民族值得反省的问题。 相似文献

The city of Kaohsiung has been urgently reducing its rates of ownership and usage of privately owned motor vehicles. The most important strategy undertaken thus far has been to build mass rapid transit systems. This study aims to apply the Involvement Theory to construct an inventory to measure level of travelers’ involvement in public transport services. The results indicate that the number of low involvement travelers is the critical factor that determines whether the new public transport system can effectively operate. They also provide authorities with precise marketing strategies targeting different groups in order to allow the new public transport systems to sufficiently meet public needs. 相似文献

磁州窑作品作为宋元时期一种文化现象,不应仅从陶瓷角度去解读,其中还包涵了宋元时期陶瓷的商品经济成长的轨迹,也反映了宋元民间风俗艺术取向与文人审美时尚合流趋势。磁州窑文化涉及宋元时代风貌、民俗风物、透视出政治、经济、文化、科技、军事等多方面的内容与信息。本文试图从磁州窑的文质来源与工巧体现着手,解读中国艺术商品史的一个典型案例。 相似文献

This study investigates the influence of consumers’ motivational orientations (“prevention” vs. “promotion”) on their susceptibility to demand‐based versus supply‐based scarcity, measured by purchase intention scores. Prevention‐focused participants were more inclined to adopt a product when it was perceived to be demand‐scarce rather than supply‐scarce, while those who were identified as promotion‐focused responded positively to scarcity attributed to supply shortfall. In addition, products that could be associated with a prevention motive enhanced purchase intentions when presented as demand‐scarce but not if perceived to be supply‐scarce; conversely, products associated with the promotion motive scored better if the scarcity was seen to be supply‐generated rather than demand‐generated. Lastly, messages focused on prevention were more effective than those focused on promotion in the case of perceived demand scarcity, whereas the converse holds true for supply scarcity. These findings highlight the importance of understanding the motivational differences underlying the effectiveness of scarcity appeals. They furthermore suggest the strategic implication that improved intention to purchase occurs when the regulatory focus evoked by a scarcity‐related message is compatible with the appeal it communicates. 相似文献
