个体非理性经济行为的心理透析 总被引:3,自引:0,他引:3
个体经济活动有时会偏离基本的"经济人"理性原则,违背一些简单的经济运算法则,做出非理性经济行为,其原因与个体存在的心理账户及其认知偏差有关。了解并掌握心理账户的本质特征,把握认知偏差的规律,不仅能合理解释个体的某些消费和投资行为,而且能为企业或政府制定消费或投资政策提供决策指导。 相似文献

证券市场为中国经济的高速发展做出了巨大贡献,但作为中国非成熟证券市场中占比70%的重要投资主体——普通投资者的投资收益却非常惨淡。普通投资者通常采用博弈型和综合判断型的投资方法,而这两种缺乏定性和定量分析的方法通常会因情绪因素和认知偏差使普通投资者很难做出客观理性的投资决策,在投资的判断与决策过程中会不由自主地受到各种心理因素的影响,以致陷入认知陷阱。通过对普通投资者的投资行为的行为金融学进行分析,揭示普通投资者投资过程中所暴露出来的自身思想和心理上的固有缺陷,这种缺陷干扰普通投资者的理性思维与判断过程,以致投资失败。 相似文献

本文以2008—2017年的季报、半年报和年报盈余公告信息为研究对象,利用Fama MacBeth横截面回归方法考察了公司高管和机构投资者的内幕交易行为。研究发现:(1)我国股票市场的盈余漂移异象在盈余公告前后具有明显的非对称性,股价倾向于在盈余公告前(后)对“好(坏)消息”反应过度、对“坏(好)消息”反应不足;(2)盈余公告前,机构投资者的资金净流入(出)与公司的未预期盈余之间呈显著正相关关系;(3)盈余漂移异象在不同板块之间存在明显的分化效应,在盈余公告前,主板市场对“好消息”的反应程度弱于中小板和创业板,而在盈余公告后正好相反。 相似文献

Whilst individual investors’ reactions to earnings forecasts have been widely documented, the impact that retractions and/or corrections have on investors’ decisions has received little attention. Further, the role that either/both mood and gender of investors play has not been investigated within this context. This is especially important as failure by individual investors to adjust correctly to retractions/corrections of earnings may have adverse investment outcomes. Our study thus investigates whether mood and gender differences influence the way in which individual investors react to retractions and corrections of management earnings forecasts. In this paper, we show that individual investors do not adjust correctly to retractions and corrections of previously disclosed information. We also find that both mood and gender play a significant role in individual investors’ reactions to such announcements. Awareness of the differences in investors’ reactions to retractions and corrections of earnings according to their mood and/or gender can provide further insights on whether their investment decisions are rational and are hence consistent with traditional models of assumed rational investment behaviour. 相似文献

This article provides experimental evidence that bidder and target shareholders of a takeover announcement exhibit differences in their actions explained by individual traits and by the environment in which investors must decide. These variables should be considered when designing an adequate investor protection policy. Before the crisis, investor protection regulation was based on the rational behaviour hypothesis and characterized by an overreliance on disclosure and financial literacy strategies. However, the new European policy on financial services has acknowledged the lack of adequate protection, and has increased transparency and access to information for investors in MIFID II and MiFIR. 相似文献

We examine whether mixed-frequency investor sentiment affects stock returns. In line with recent evidence from China, we find that the aggregate effect and the individual effect of mixed-frequency investor sentiment are statistically significant, and mixed-frequency investor sentiment is more important than the low-frequency one. Moreover, mixed-frequency investor sentiment, which is mixed by high-frequency data, can be more important than the market premium. 相似文献

在证券市场上,由于契约和法律的这种外来的保护不完备,投资者需要对其权益进行自我保护。本文在探讨投资者信心、投资者行为与投资者教育的关系的基础上,通过政府主导的投资者教育事件研究,指出我国当前政府主导的投资者教育活动具有"双刃剑"的效果:既可提高投资者的投资知识和技能,增强其投资信心,又可能由于制度路径依赖的存在,损害投资者利益。政府教育的效果取决于其组织实施的方式和方法,也取决于投资者对政府教育的正确解读。 相似文献

AbstractEconomics and business students are taught that sunk costs are irrelevant to their decisions. Yet, there is ample evidence that managers fail to integrate this simple rule and fall prey to what is known as the sunk-costs bias. To mitigate cognitive biases, such as the sunk-cost bias, educators must raise students’ awareness of these common judgment errors. In this article, the author proposes a classroom activity that actively engages students and allows them to identify this bias in their own judgments. The activity builds on a series of experiments from the psychology literature. The author discusses how these experiments have been adapted for classroom use and presents evidence suggesting that the activity increased students’ awareness of the sunk-cost bias and improved their decision-making skills. 相似文献

产权所有制、交易方式与交易绩效相关性研究——来自上海产权市场的经验数据检验 总被引:1,自引:0,他引:1
文章分析了国有与非国有两种所有制交易主体在竞价和协议转让两种交易方式下的交易绩效差异,提出了相应的假设,并进行了实证检验.研究结果表明,国有产权相对于非国有产权存在低效率现象;通过竞价方式形成的市场化竞争机制,可以有效解决国有产权与非国有产权的交易绩效差异问题,形成更高的溢价率;协议方式有助于节约交易时间,但在溢价率和费用等方面劣于竞价交易. 相似文献
