卖方分析师佣金解绑改革与中国实践--基于MiFIDⅡ的思考

卖方分析师利益冲突问题损害了投资者利益以及市场稳定性。为提高分析师独立性,欧洲2018年出台的《欧盟金融工具市场指令Ⅱ》首次拆分了分析师的分仓佣金与研究费用。研究发现,该举措实施后,伴随着卖方研究质量提升、低质量分析师退出市场,分析师利益冲突问题得到缓解,促进了卖方服务内部化转型、买方研究加速形成以及投资者交易透明度的提升,但同时也带来了研报价格恶性竞争、市场信息环境受损、人才非优流动等负面影响。我国分析师佣金制度存在披露透明度不足、研究服务界定不明、佣金分配缺乏有效监管等问题,现阶段完全解绑佣金可能引发潜在风险,应采取相对柔性的改革思路。监管机构宜推动改革基金管理费用,塑造市场激励机制;券商应提升综合研究能力,推进业务模式转型,探索差异化发展之路。

论在我国保险法上确立合理期待原则

美国保险法上的"满足被保险人的合理期待"的法律理念自提出并被不少国家逐渐接受后,目前已发展成为一种全新的格式合同解释原则."合理期待原则"的产生和存在有其历史背景和理论基础,传统合同救济办法不能对被保险人提供有效救济是其产生的直接动因,保险合同为射幸合同,其所具有的悬殊的对价特征是其产生的根源,在本质上是公平原则的必然...

基于成本分析与指导价格的超载治理研究——以湖南省的调研数据为例

以湖南省的公路货运调研数据为基础,结合经济学的成本理论建立成本分析模型进行研究发现:我国货运超载的主要原因是货运市场长期均衡决定的运价水平低于额定载重量下的平均成本。因此,从维护运输业者利益的角度出发,应从四个方面加以改进:第一,政府应建立和完善公路货运行业的准入与退出机制,相机调控其规模;第二,针对公路货运价格过低的现状,政府应制定和推行指导价格以保证货运行业的健康发展;第三,继续合理增强对超载运营者的惩罚力度,打击和遏制超载行为;第四,针对我国公路货运相关税费较高的情况,政府应适量减免税费。     

Systematic Mortality Improvement Trends and Mortality Heterogeneity: Insights from Individual-Level HRS Data

Providers of life annuities and pensions need to consider both systematic mortality improvement trends and mortality heterogeneity. Although how mortality improvement varies with age and gender at the population level is well studied, how trends vary with risk factors remains relatively unexplored. This article assesses how systematic mortality improvement trends vary with individual risk characteristics using individual-level longitudinal data from the U.S. Health and Retirement Study between 1994 and 2009. Initially a Lee-Carter model is used to assess mortality improvement trends by grouping individuals with similar risk characteristics of gender, education, and race. We then fit a longitudinal mortality model to individual-level data allowing for heterogeneity and time trends in individual-level risk factors. Our results show how survey data can provide valuable insights into both mortality heterogeneity and improvement trends more effectively than commonly used aggregate models. We show how mortality improvement differs across individuals with different risk factors. Significantly, at an individual level, mortality improvement trends have been driven by changes in health history such as high blood pressure, cancer, and heart problems rather than risk factors such as education, marital status, body mass index, and smoker status.     

An Ex Post Assessment of Investor Response to Catastrophes

A large body of research has examined abnormal stock returns for insurance companies in the wake of major catastrophes. Most of these studies have investigated the ex ante factors that investors may consider when generating expectations of future profits, represented by postcatastrophe stock returns. We instead ask whether these expectations were ultimately correct by investigating the relationship between returns and the disaster’s effect on future earnings. We find that returns immediately following a disaster are not associated with future earnings. Approximately six days following a catastrophe, however, returns begin to show a significant positive relationship with future earnings. This relationship becomes stronger in subsequent days. We conclude that investors are unable to correctly predict a disaster’s net impact on profits immediately after a disaster because existing public information is insufficient or misunderstood. Only once insurers begin disclosing their estimated losses can investors make accurate predictions about a disaster’s effect on earnings. Our study shows that the investor expectations inferred in much of the existing literature are not predictive of future profits. Our findings are consistent with semistrong-form market efficiency in the wake of a major disaster.     

The influencing factors of satisfaction and lending intention in online lending investment: an empirical study based on the Chinese market

This paper develops a platform‐based influencing factors model which considers value perception, risk prevention measure, non‐default experience, trust and incentive gap, to better examine the impact of platforms on investors’ satisfaction and lending intention based on the Chinese market. The results reveal that the first four factors positively influence the satisfaction of the investors, while the incentive gap has a negative impact, and there is a positive association between investors’ satisfaction and lending intention. Some specific features of China’s online lending market are identified, which provides valuable insights for online lending platforms and the government.

Inferring latent social networks from stock holdings

We infer the latent social networks of investors using data on their stock holdings. We map linkages to portfolio weights using a portfolio-choice model. The precision of an investor’s private signal about firm value is assumed to increase with his connections in the city where the firm is headquartered. Using money-manager data, we find that managerial linkages to a city are overly dispersed relative to the Erdös–Rényi model of i.i.d. connections. Managers at the tail of this distribution with non-i.i.d. linkages have more university alumni in that city. Their stock holdings there outperform their holdings in other cities.
