本文结合了利益冲突和认知偏差两个角度研究了分析师预测偏差产生的原因.考察了利益冲突的三种形式,基金持股利益,承销商利益和分析师声誉.实证发现:首先,基金持股率的高低对分析师的预测偏差存在显著影响,基金持股率越高,分析师的预测偏差越大,说明基金持股利益冲突存在;其次,承销商分析师和非承销商分析师的预测并不存在显著差异,即国外的承销商利益驱动的解释,不适用于国内,认为这是国内外分析师的利益来源不同导致
在中国人口老龄化日益加剧、社会养老压力日益沉重的背景下,住房反向抵押贷款养老模式能够较好地解决部分老年人的养老困难,是中国现阶段社会养老保障体系的一种有力补充.住房反向抵押贷款的风险管理是中国推行住房反向抵押贷款养老模式需要重点考虑的核心问题之一.现有研究主要集中在住房反向抵押贷款的可行性和定价方面,本文从风险管理的视角出发,首先分析了住房反向抵押贷款养老模式存在的各种风险,在此基础上运用效用理论

本文根据养老金测算的平行四边形框架,考虑中国企业职工基本养老保险不同年龄参保人群的养老金构成不同,用未来法建立统筹账户养老金应计负债的精算模型.通过养老金与缴费工资间的关系、人口的年龄性别分布情况估计工龄工资增长率及同年度养老金随年龄增长率,依据基准精算假设,测得2015年初企业职工统筹账户养老金精算应计负债为72.13万亿元,其中女性统筹账户养老金精算应计负债占61.31%,性别差异明显.基于测
中国十三五规划提出要采取措施帮助连片特困区七千多万贫困人口脱贫.连片特困区属于中国贫困程度严重、生态非常脆弱的山区,特殊的自然、社会、经济特征使得这些区的农户面临着多种风险,开展政策性农业保险,建立农业风险防范机制,有利于增强农户的风险抵御能力,有效稳定农民生产生活,但特困区农户参与农业保险的积极性并不足.本文依据风险管理和保险学相关理论,对连片特困区农户的参保行为进行理论和实证分析,以农户个人特
