I examine whether stock ownership by politicians helps to enforce noncontractible quid pro quo relations with firms. The ownership by US Congress members in firms contributing to their election campaigns is higher than in noncontributors. This bias toward contributors depends on the financial incentives of politicians and the relation's value. Firms with a stronger ownership–contribution association receive more government contracts. The financial gains from these contracts are economically large. When politicians divest stocks, firms discontinue contributions to the politicians, lose future contracts, and perform poorly. Politicians divest the stocks in contributors, but not in noncontributors, in anticipation of retirement. 相似文献

The empirical results of the risk-return relationship are mixed for both mature and merging markets. In this paper, we develop a new volatility model to revisit the risk-return relation of the aggregate stock market index by extending the Realized GARCH model of Hansen et al. (2012) with the Wang and Yang (2013) framework, in which the overall risk-return relation is decomposed into a risk premium and a volatility feedback effect. An empirical analysis of three major Chinese stock indices reveals positive risk premium and negative volatility feedback effect, and those findings are stable across different markets and sub-samples. However, their relative magnitudes differ between markets and varies through time. 相似文献

唯物主义理论有着不同的理论形式和形态,这些理论形态或形式随着人类的实践的深入而不断改变。近代工业革命以来,唯物主义建立在牛顿力学的基础上,将自然看作机械的,以开发自然、征服自然为旗帜。但工业革命所带来的环境问题、生态问题在现代则越来越困扰、甚至威胁着人类的生存。唯物主义就必须改变它的内容与形态,以自然之子的态度定位人与物质宇宙的关系,崇仰宇宙、敬畏宇宙,不是从纯粹知的形式,而且也从爱的、情智的关系上理解唯物主义的内涵与唯物主义的新形式。 相似文献

针对不完备信息系统条件下的辐射源威胁等级判定问题,提出了一种基于改进容差关系粗糙集(ITR-RS)的不完备信息系统辐射源威胁等级判定方法。该方法将粗糙集中的不完备信息系统理论引入辐射源威胁等级判定中,并构建一套完备的决策规则提取模型。此外,利用辨识矩阵实现对属性的约简,在降低系统所需处理数据量的同时,提高了算法的实时性;在容差关系粗糙集的基础上,提出一种改进的容差关系,在属性主、客权重相结合的基础上引入阈值来划分加权阈值容差类,得到更为合理、准确的决策规则。仿真试验及分析表明,与经典RS算法相比,所提算法的威胁等级判定正确率提高了23%,可用于信息系统不完备条件下的辐射源威胁等级判定。 相似文献

Owing to a lack of construct reliability and validity of environmental management measurements, advancements in understanding hotels’ environmental management practices have been somewhat limited. The goal of this paper is to propose a uniform and parsimonious scale that captures Hotels’ Environmental Management Initiative (HEMI) with the most common three dimensions in the hotel industry: environmental resource conservation efforts, environmental policy and training, and environmental public relation efforts. After the refinement of the initial items, the scale was confirmed with cross-cultural data obtained from full-time hotel employees in two Asian countries. The twenty-one item HEMI scale demonstrated a satisfactory level of content, convergent, discriminant, cross, and criterion-related validity. The proposed HEMI scale will serve as a useful tool for future hospitality scholars who would like to further explore the impact of hotels’ environmental management initiatives on employees’ attitudes and behaviors toward the environment and their environmental performance. 相似文献

Valuing Initial Public Offerings Using Article 11 Pro Forma Financial Information in the Prospectus*
We investigate whether Article 11 pro forma financial information assists investors in valuing IPOs. While the SEC expects it to be helpful in assisting investment decisions, Article 11 pro forma financial information is based on registrants' understanding and assumptions, and registrants can exercise their own judgment when preparing pro forma financial statements. It is therefore an empirical question whether the information contained in pro forma financial statements is useful to investors. We examine the association between pro forma adjustments of earnings and book value of equity and the IPO offer value and find asymmetric results. While positive pro forma adjustments of earnings and book value of equity are positively associated with the IPO offer value, negative pro forma adjustments of earnings and book value of equity are negatively associated with the IPO offer value, suggesting that negative pro forma adjustments are priced as growth opportunities. Additional analyses reveal that the association between pro forma adjustments of book value of equity and the IPO offer value varies across different time periods and industries and that pro forma adjustments of book value of equity are initially mispriced by investors. In contrast, we do not find similar results for pro forma adjustments of earnings. Further empirical tests show that the asymmetric results of mispricing of pro forma adjustments of earnings and book value of equity may be explained by the requirements of Article 11 of Regulation S‐X for pro forma adjustments dictating that adjustments to earnings reflect only recurring items while adjustments to book value reflect both recurring and nonrecurring items. 相似文献

目前,我国司法实践中,刑事司法的不公多表现在量刑上,一些地方法院量刑畸轻畸重的现象比较突出,而且这种现象一旦发生,再行纠正比较困难。为解决这一问题,法律应明确规定检察机关的量刑请求权。目前,该项权利在实践中没有得到实体法与程序法的规制,多停留在制度设想上。为能够使量刑请求权具有操作可行性,有必要对该项权力实施的时间、方式以及程序做进一步研究,并协调好检察机关内外的各种关系。 相似文献
