国际碳市场与能源市场动态相依关系研究与启示——基于DCC-MVGARCH模型

本文应用基于条件多元t分布的DCC-MVGARCH模型研究CERs期货价格收益同能源期货价格收益之间的动态相依关系,旨在探讨跨品种套期保值的可行性及操作策略,为国内减排企业及时对冲CERs价格波动风险提供经验依据。实证结果显示:CERs期货价格收益和能源期货价格收益之间存在正相关性;相较Euro天然气期货合约与GlobalCoaL期货合约,BRenT原油期货合约更适用于构造套期保值组合;以动态条件相关系数测算时变套期保值比率明显降低了组合收益的方差并提升了组合收益的均值,其套期保值绩效要优于条件相关系数。基于此结果本文认为,国内减排企业应当积极采取相关套期保值策略并定期更新动态条件相关系数均值,政府主管部门亦应着手实施碳资源战略储备以对冲风险。     

Measuring service experience: a utility-based heuristic model

This research aims to construct a model to evaluate service experience. We develop a novel model for service experience by incorporating positive and negative dimensions. We demonstrate that greater utility from experience results in greater value of service experience. We also discovered negative dimensions are the key reason; especially waiting time. We separated five groups to help firms explore deeper insights from various dimensions. The value of service experience in group of middle range has the greater contrast between positive and negative dimensions than the other groups. Service providers can obtain customer perception to adjust or revise the service components.     

Does prior record matter in the wealth effect of open-market share repurchase announcements?

This study investigates whether prior experience of share repurchases matters in the market reactions to the subsequent repurchase announcements. Specifically, we study the prior record on actual buybacks and post-announcement stock performance. We find that upon the announcement of share repurchases, stock markets not only respond more positively to those made by firms that have better record on actual buyback following their previous repurchase plan announcements, but also experience a stronger reaction for announcing firms with better stock performance after prior repurchase announcements. These results hold even after controlling for other variables that are found important in influencing the market reactions to repurchase announcements.     

上市公司内部控制信息披露情况研究

企业的内部控制程度对外主要体现在内部信息披露的情况。我国目前对内部信息披露的控制已有了较为完备的规范体系，但执行情况还不容乐观。文章首先介绍了国内外的内部控制信息披露发展情况，然后选取上海证券交易所161家制造行业企业的内部控制信息披露情况作为样本，具体研究了我国《企业内部控制基本规范》实施之前各企业的内部控制信息披露情况。结论显示，在《企业内部控制基本规范》实施之前，我国绝大多数企业没有进行内部控制自我评估报告的注册会计师审核，披露状况让人堪忧。

地理和禀赋的梯度变化与出口产业集聚的空间调整

文章在出口贸易条件的假定下,构建了一个包含自然地理和劳动力禀赋的基于生产者最优决策的出口产业集聚模型,以解释出口产业率先在中国沿海地区集聚的原因,并通过劳动力流动的"空间溢价"和出口运输距离来界定区位的地理与禀赋的梯度变化,得出劳动力工资与运输成本相互替代且包含集聚效应影响的均衡方程,并以此进一步对中国出口产业在沿海和内地之间的空间调整和空间均衡作深入分析。     

移动动态安防系统

随着个人私有电子设备日益完善，大量隐私信息存储于这些电子设备中，非法的越权访问导致了这类隐私信息的大量流失，本系统实现了远程监控、监督由于时间和空间阻隔而不能实时操控的电子设备的运行状况。     

Effectiveness of promotional premiums: The moderating role of affective state in different contexts

This research explores the influence of affective state on ad and product judgments for advertising that features promotional offers of high and low price value. Consistent with expectations, Study 1 found that for happy participants, high‐price value premiums generated higher ad believability ratings, which in turn enhanced ad and brand attitudes. For sad participants, however, the positive effects of high‐price value premiums were attenuated due to message believability discounting. It is proposed that the moderating influence of affective state on responses to ads featuring premiums should be more likely to emerge when attention to premiums is high, as in situations where ads feature less important product attributes or when consumers plan to purchase a product. Study 2 found that the interaction between affective state and premium value was significant when ads featured less important product attributes, but not when they featured important product attributes. Study 3 found that the interaction was significant for participants who intended to purchase the product in the near future, but not for those who did not have purchase intentions. © 2009 Wiley Periodicals, Inc.
