Does educational diversity of managers matter for the performance of team‐managed funds?

We study the effect of the educational diversity of managers on the performance of team‐managed mutual funds using a large sample of U.S. equity funds from 1994 to 2013. We consider diversity in terms of both final educational degree and field of educational specialisation. We find that, in general, both types of diversity have a positive impact on fund performance, and our results are robust over a wide range of performance metrics and changes in market conditions.

资本结构、股权结构与中小企业成长性——基于中小企业板数据的实证分析

本文以中小企业板上市企业2004-2009年数据为基础,以资产市值账面比衡量企业成长性,分析了我国中小上市企业资本结构和股权结构对成长性的影响。实证结果表明,资产负债率和长期负债率均对成长性具有显著正向影响,意味着较高的负债能降低外部权益成本,有利于中小上市企业的成长。成长性与股权集中度显著正相关,表明股权集中有利于股东对管理层进行监督,降低代理成本并能促进中小上市企业成长。管理层持股比重的改变对中小上市企业的成长性无显著影响。     

股指期货对资产管理行业的影响——基于新兴古典经济学视角

本文从新兴古典经济学的视角探讨股指期货对中国资产管理行业的影响,以及股指期货对中国资本市场的结构性影响.从理论视角来看,基金业规模经济的实现途径是通过不断提高基金业的专业分工水平,增强基金业的生产力而实现.这种专业分工分为横向、纵向两种扩张.公募基金的投资管理能力横向扩张,指的是从传统的股票和债券市场延伸到金融衍生工具市场、实业投资等领域,投资能力纵向的分解,是将基金的收益分解为Alpha和Beta两部分.随着股指期货的推出,国内公募基金的投资管理沿横向、纵向的扩张,成为现实、具体的可能.投资策略的演变推动投资部门的变化,使投资策略经历再构造过程,形成Alpha和Beta的分离,并促进Beta产品、Alpha产品的深化发展.     

普惠金融距离视角下中国对“一带一路”OFDI的影响效应分析

普惠金融体系在"一带一路"中的完善与发展是"一带一路"倡议实现贸易畅通和资金融通的核心环节。基于此,采用2011-2018年"一带一路"51个沿线国家数据,测度沿线国家普惠金融发展水平及其与中国普惠金融发展水平的距离,并进一步考察普惠金融距离对中国向沿线国家对外直接投资的影响。结果表明:"一带一路"沿线国家普惠金融水平普遍较低,中国处于领先地位;普惠金融距离对中国向沿线国家对外直接投资具有明显不同的长短期效应;而就分层而言,中国对不同圈层国家对外直接投资的规模与流向受普惠金融距离影响效应存在显著差异。最后,依据实证结论,得出相关政策启示。     

Institutional quality,investment efficiency,and the choice of public–private partnerships

We examine a sample of 625 public–private partnership (PPP) firms from 1980 to 2015 that straddle nine countries with varying degrees of economic development and PPP markets. We find that the motivations of the firms that undertake PPP investments vary. While private sector firms in economies with low institutional quality choose to engage in PPPs to alleviate capital constraints attributed to underinvestment, those in economies with high institutional quality participate in PPPs to solve the problem of overinvestment due to an abundant cash flow. In the long run, the benefits of lower capital constraints through PPP investments are more pronounced in economies with high institutional quality.     

中国股市反应偏差的投资者心态模型

在行为金融学理论中,投资者心态模型将投资者的心理偏差当作反应偏差的源泉,但这些投资者心态模型对于发展时间较短、具有区别于成熟市场的独特市场制度和社会环境的中国股票市场而言,存在适用度问题。分析中国股票市场投资者普遍的投机心理等要素,运用改进了的HS模型,根据股票市场的习惯,分别对一个牛市周期和熊市周期进行验证得出,投机心理支配下的机构投资者和个人投资者的相互作用是导致反应偏差的主要原因。     

Optimal insurance in the presence of reinsurance

This paper studies an optimal insurance and reinsurance design problem among three agents: policyholder, insurer, and reinsurer. We assume that the preferences of the parties are given by distortion risk measures, which are equivalent to dual utilities. By maximizing the dual utility of the insurer and jointly solving the optimal insurance and reinsurance contracts, it is found that a layering insurance is optimal, with every layer being borne by one of the three agents. We also show that reinsurance encourages more insurance, and is welfare improving for the economy. Furthermore, it is optimal for the insurer to charge the maximum acceptable insurance premium to the policyholder. This paper also considers three other variants of the optimal insurance/reinsurance models. The first two variants impose a limit on the reinsurance premium so as to prevent insurer to reinsure all its risk. An optimal solution is still layering insurance, though the insurer will have to retain higher risk. Finally, we study the effect of competition by permitting the policyholder to insure its risk with an insurer, a reinsurer, or both. The competition from the reinsurer dampens the price at which an insurer could charge to the policyholder, although the optimal indemnities remain the same as the baseline model. The reinsurer will however not trade with the policyholder in this optimal solution.     

裂缝性潜山变质岩油藏的合理生产技术对策——以鸭儿峡油田志留系油藏为例

裂缝性潜山变质岩油藏的生产特征复杂,以鸭儿峡油田志留系为例对该类油藏的开发特征进行了分析。结果表明,油藏开发过程中高产井产量递减速度快、累积产油量高、持续时间长,低产井生产状态不稳定,注水初期油井见效明显,油藏含水变化复杂。油井转注、分层酸化压裂、卡水和深抽提液措施实施后油井含水下降,产油量明显上升,显示出良好的开发效果,为后期稳产提供了坚实的技术保障。
