金融危机之后,股价大幅下挫,投资水平也大幅缩减,投资和股价之间的敏感性问题重新引起人们的关注.股票市场是否以及如何影响实体经济的问题成为一个现实话题.事实上,投资和股价之间的敏感性间题既是一个规范问题,又是一个实证问题.系统梳理新古典金融学和行为金融学框架下的投资股价敏感性问题研究,有利于澄清现阶段的一些争论. 相似文献

Consumer resistance and inertia related behaviors are as important as adoption behaviors. Resistance can lead to unwillingness on the part of the investors to invest in a particular financial product. On the other hand, inertia can potentially lead to loyalty, despite dissatisfaction with a financial product. Consequently, an understanding of the antecedents and outcomes of retail investors’ resistance and inertia toward investments is valuable for firms selling investment products. Although the literature on resistance and inertia is around three decades old, empirical research related to retail investment decision making has only recently gained momentum, resulting in limited but interesting findings. The current study utilizes a systematic literature review (SLR) methodology to review prior studies in this domain. The SLR presents research profiling and an extensive content analysis of the studies selected by applying a robust search protocol. The study findings highlight numerous aspects of retail investment behavior, underscore research gaps in the prior literature, and offer recommendations for future research. Furthermore, a comprehensive framework, labelled resistance adoption inertia continuance (RAIC), is proposed to investigate the behavior of retail investors. The study concludes with meaningful theoretical and practical implications that can help counter resistance and inertia toward different financial products. 相似文献

文章重点探讨媒体关注对我国IPO抑价影响的具体路径。基于上市公司IPO及之前的媒体信息,选取创业板IPO公司作为研究样本,从行为金融学视角对抑价理论进行实证检验。经路径研究发现,高媒体关注通过配置投资者“有限注意力”导致高发行抑价,在个人投资者比例较高的创业板市场上,媒体关注对IPO抑价的影响路径是基于情绪效应而不是认知效应。 相似文献

This article analyzed 58 Brazilian journals in order to address the gap unexplored in the past 10?years by congresses and periodical journals. In this research, an analysis based on keywords was used, followed by analysis of citations and co-citations that allowed to verify: an average growth of 20% p.a. of publications; the most common focus was replication of Kahneman and Tversky; the most studied group tended to be university students; quality has failed to accompany the increase in publications; public institutions publish more. A gap was perceived in the surveying of financial managers and investors, as well as bias and heuristics as a subject. 相似文献

本文引入微观法与金融学的研究成果,构建了一个从投资者保护不足,到企业投融资行为扭曲,最终衍生为破坏性成长的理论解释框架,并基于国内外相关文献综述和国内上市公司数据进行了实证检验,结果显示:国内投资者保护程度明显不足,由此造成的企业过度投资和投资效率低下引发规模扩张和效益提升的背离,也就是所谓的破坏性成长。因此,经济转型也需要关注微观层面的制度校正,通过完善投资者保护机制最终约束微观主体的投融资行为,提高资金配置效率。 相似文献

中国目前房价过高、上涨过快的问题,从作为二线城市的哈尔滨近年来房价异常的走势也能够得到印证。形成高房价及房价泡沫的根本原因在于地方政府基于"土地财政"利益的幕后推手,并由此形成了地价推动下的房价内生上涨机制。高房价的负面影响很严重,尤其在民生和潜在政治危害等方面。彻底治理高房价及其泡沫的出路是改革现行土地出让金分配方式,由中央财政统筹安排。 相似文献

本文立足于投资者认知特征的视角,探讨投资者注意力对上市公司投资效率的影响,以及制度环境的制约作用。研究发现,投资者注意力在一定程度上可以缓解投资不足,但是这种效果并不体现在对投资过度的抑制方面。进一步分组研究结果显示,在企业投资过度时,投资者注意力的强化能使得企业获得更多的外部融资,但在投资不足时此现象并没有出现。当加入外部融资作为控制变量时,投资者注意力与投资效率之间相关系数的显著度并未发生明显变化,说明投资者注意力对投资效率的影响不是通过外部融资的路径实现的。此外,市场化程度高能有效缓解信息不对称程度,弥补投资者注意力的稀缺。 相似文献

本文探讨了法与金融学对转型经济的研究以及这种研究对法与金融学发展的影响。本文的分析结论表明:一方面法与金融学对转轨经济中的许多经济现象提供了富有洞察力的解释,并成为进一步研究转型经济的重要"利器";另一方面,这也促使法与金融研究范式自身的重要转型,进而丰富法与金融理论体系以及它与经济学其他研究领域的融合。 相似文献

投资者注意力从认知心理学视角开启了行为金融学新的研究范式,并对金融资产定价和财务行为产生了深远的影响。而实证研究中如何科学测度投资者注意力一直是该领域研究的难点问题。文章通过对已有文献的梳理,从竞争性信息的干扰程度、信息的显著和易处理程度以及交易特性三个方面对投资者注意力的测度文献进行了系统整理和分析,重点在导入认知心理学的理论基础上,对比分析了这三方面指标的优缺点、注意问题及其适应范围,最后提出了未来的研究展望。 相似文献

文章利用2013-2018年深圳证券交易所上市公司的数据,实证检验了机构投资者实地调研对投资-股价敏感性的影响。研究发现,机构投资者实地调研提高了公司投资-股价敏感性,在股价信息含量越高时,机构投资者实地调研对公司投资-股价敏感性的影响越显著,表明投资者实地调研通过信息反馈效应中的\"挤入渠道\"增强了管理层向市场的学习行为,机构投资者实地调研对投资-股价敏感性的影响在管理层持股的上市公司中更为显著。研究结果表明,机构投资者实地调研可以帮助上市公司管理层获取更多决策有用信息,提升资源配置效率,对于完善机构投资者调研制度、提升我国资本市场信息效率具有一定的实践价值。 相似文献

近年来,承载着引导资金投向等多项使命,各类绿色指数相继发布,然而绿色指数是否真的对市场产生了影响有待验证。文章以2017-2019年绿色领先类公司股票数据为样本,采用事件研究法分析绿色指数发布后样本公司收益率的变化,借以探究绿色指数发布的股价效应。实证结果表明:在短期内,绿色指数发布对样本公司股价影响显著,指数发布后,公司的异常收益率在整体上显著为正。而长期来看,该股价效应不具备持续性,平均异常收益率会在长期回落。进一步,文章基于投资者情绪的视角,对该股价效应背后的影响机制做出了梳理。研究结果表明,绿色指数发布后,投资者情绪明显高涨,并且这种情绪对事件日后的异常收益有显著的正向影响。文章的研究为评价绿色指数发布的影响提供了良好的参考,同时对于内在机制的挖掘在一定程度上弥补了既有研究的不足。 相似文献

Although several studies have examined the economic consequences of large shareholders' tunneling behavior, little attention has been paid to the negative effects of tunneling on firms' extreme events. In this article, we investigate how tunneling behavior affects firm-level stock price crashes. The findings indicate that the probability of stock price crashes is positively associated with the extent of tunneling behavior by large shareholders. The positive relationship is more pronounced after the split of share structure reform and is moderated by the firm's financial conditions. This study contributes to the emerging body of literature focusing on the economic consequences of tunneling and stock price crashes. The conclusions drawn from the study also provide a frame of reference for investor protection and investment portfolios based on large shareholders' tunneling behavior in China. 相似文献

Firms use derivatives both for hedging and nonhedging purposes. The Statement of Financial Accounting Standards No. 161 (SFAS 161) requires firms to disclose the purposes of their derivatives usage, thereby helping investors to evaluate the effects of derivatives usage on firm performance. Using a hand-collected sample of US listed firms and a difference-in-differences research design, we find that, compared with nonderivative-users, derivative-users compliant with SFAS 161 experience a significantly greater reduction in stock illiquidity and the probability of informed trading in the post-SFAS 161 period, and such impact is evident only for firms with a high degree of investor attention. 相似文献

文章以发行人筹资收益最大化为假设,对市场热季周期下发行人、承销商与投资人三者之间的博弈过程以及投资者情绪对首次公开募股(IPO)市场定价的影响机制进行研究.研究结果表明,发行人最优发行数量小于市场需求数量、承销商定价低于市场需求价格的目的在于确保发行成功和获取日后收益;投资者高亢的投资情绪可以对IPO市场短期收益正偏和长期收益负偏成为普遍现象进行解释. 相似文献

Pricing is one of the most crucial determinants of sales. Besides the actual price, how the price offering is presented to consumers also affects consumer evaluation of the product offering. Many studies focus on “price framing,” i.e., how the offer is communicated to the consumer —is the offered price given along with a reference price, is the reference price plausible, is a price deal communicated in dollar or percentage terms. Other studies focus on “situational effects,” e.g., is the evaluation for a national brand or a private brand, is it within a discount store or a specialty store. In this article, a meta-analysis of 20 published articles in marketing examines the effects of price frames and situations on perceived savings. The results reveal many features that significantly influence perceived savings. For instance, while both the percent of deal and the amount of deal positively influence perceived deal savings, deal percent has more impact. Further, the presence of a regular price as an external reference price enhances the offer value of large plausible deal and implausible deals, but not of small plausible deals. Thus, high value deals should announce the regular price, but not low value deals. Overall, the results have several useful insights for designing promotions. 相似文献

近年来,随着环境政策日趋严格,环境负面消息累积导致的股价崩盘风险不断提高。文章基于2007-2019年中国沪深两市A股重污染企业的经验数据,探讨了环境管理体系认证对股价崩盘风险的影响。研究发现,环境管理体系认证能够显著抑制股价崩盘风险,且当媒体关注越高、分析师关注越高时,环境管理体系认证对股价崩盘风险的抑制作用更强。进一步探讨影响机制发现,环境管理体系认证主要通过治理机制和信息机制来影响股价崩盘风险,换言之,环境管理体系认证能够通过提高公司环境绩效和公司信息透明度来抑制股价崩盘风险。研究结论揭示了环境管理体系认证具有资本市场有效性,丰富了股价崩盘风险的影响因素研究,对于政府完善环境管理体系认证制度以提高资本市场稳定性、企业优化战略决策以提升企业价值具有重要的借鉴意义。 相似文献
