股权分置改革、管理层薪酬业绩敏感性与机构投资者治理效应——基于中国上市公司的经验证据

股权分置改革是影响我国上市公司治理的重大制度变革,而管理层薪酬业绩敏感性是衡量公司治理有效性的常用指标。文章旨在分析与检验股权分置改革前后我国上市公司管理层薪酬业绩敏感性的变化以及机构投资者在这一过程中的治理效应。基于2002年-2008年我国A股面板数据的经验证据显示:股权分置改革后,我国上市公司管理层薪酬业绩敏感性总体上得到了提高;机构投资者有助于提高管理层薪酬业绩敏感性,但在股权分置改革前后的变化不显著;相对于境内机构投资者,合格境外机构投资者在股改后显著提高了管理层薪酬业绩敏感性。     

影子价格长短期划分及其计算

影子价格对资源配置具有重要的指导意义。但是影子价格的定义方式通常与短期生产相联系,而长期生产多资源要素的变化往往被忽视。区分生产短、长期,通过方向导数来确定长期生产资源调整的影子价格。     

发电设备寿命周期费用影响因素的敏感性分析

阐述了发电设备全寿命周期费用（Life Cycle Cost,LCC）的基本理论及计算方法,针对发电设备LCC的影响因素之间存在的客观联系,假定因素之间相互独立,对其中某2个因素的变动幅度进行了一定的修正,使之更贴近实际。以某2×600MW火电机组为例,选取若干影响因素,求得其全寿命周期费用净现值。对目标净现值进行单因素和多因素敏感性分析,以寻找目标值与影响因素之间所存在的内在联系,为设备投资以及后期优化管理提供决策依据。

Analysis of Employee Performance during Cross-cultural Service Encounters at Luxury Hotels in Hawaii,London and Florida

Globalization has motivated managers and scholars in the tourism industry to focus more attention on the problems and characteristics of the cross-cultural service encounter. During these interactions, differing cultural norms and values often create misunderstanding and conflict, which can result in an unhappy customer, a frustrated service provider and lost business. Therefore, the focus of this study was to analyze the effect of intercultural sensitivity on tourism employee performance in cross-cultural service encounters in three similar, but distinct service-dependent markets: the Hawaiian Islands, Greater London (UK) and the state of Florida. The results indicate that tourism employees with high intercultural sensitivity generally scored significantly (p < 0.05) higher than employees with low intercultural sensitivity in terms of service attentiveness, revenue contribution, interpersonal skills, job satisfaction and social satisfaction as they relate to cross-cultural encounters. There was no significant difference in results for motivation to work, tenure (years at present organization) and primary rewards (compensation, recognition, etc.). Implications of the findings are discussed.     

Litigation risk,accounting quality,and investment efficiency

This paper examines the moderating effect of litigation risk on the relationship between accounting quality and investment efficiency. We use directors’ and officers’ (D&O) liability insurance as a proxy for litigation risk, accruals quality for accounting quality, and investment cash flow sensitivity for investment efficiency (Biddle & Hilary, 2006; Hovakimian & Hovakimian, 2009). Using Canadian data from 1998 to 2008, we show that firms with higher D&O insurance coverage exhibit lower quality accruals. Moreover, the previously documented negative association between accruals quality and investment cash flow sensitivity is stronger (weaker) when abnormal D&O coverage is low (high), suggesting that the role of accounting quality in facilitating investment efficiency is conditional upon observable litigation risk.
