偿二代与资产负债匹配约束下寿险公司最优资产配置

保险公司资产配置需要同时考虑资产负债匹配和风险-收益均衡.本文在偿二代对保险资产负债匹配的隐性要求和保险资产负债管理监管规则对资产负债匹配的显性要求下,考察了资本占用和久期匹配约束下的险资投资策略,研究了保险公司的最优资产配置问题.结果 显示:负债久期较长的寿险公司很难同时满足偿二代资本要求和资产负债久期匹配要求;保险资产负债管理监管规则对保险公司资产配置策略产生显著影响;资产收益特征设定下,保险公司资产配置策略有改进空间.本文的创新点是依据保险资产负债管理监管规则显性地引入资产负债匹配要求,同时在偿二代与资产负债匹配约束下研究了寿险公司最优资产配置.     

“偿二代”体系下保险资产配置策略及效率评估

以风险为导向、以资本金为约束的第二代偿付能力监管体系(以下简称“偿二代”),不同资产类型对资本金的要求存在显著的差异。偿二代体系下,如何平衡资产配置的收益、风险及资本占用值得认真思考。本文考察了资金占用为约束下的资产配置优化问题,采用遗传算法,得出了不同风险态度对应的帕累托最优解。为了对资产配置策略的效率进行评估,论文从收益、风险、流动性和资本占用情况四个方面将偿一代体系、偿二代体系与传统的Markowitz模型下的资产配置策略进行对比。研究发现,在施加了偿付能力约束后,可行域是Markowitz模型下的一个子集;偿二代下有效边界优于偿一代下的有效边界,偿二代下资本的使用效率提高了。     

资产周期特性与保险公司资产配置策略

在竞争激烈的保险市场上,作为盈利的两大支柱之一,保险公司资产管理的能力日趋重要,而保险公司资产配置是保险资产管理的核心,其研究意义就显得尤为重要。本文首先给出保险资产配置的意义与总体原则,然后从保险资金的来源和特性入手,在详细分析了美国、中国不同经济周期和市场周期下大类资产风险收益特性的基础之上,给出保险公司资产负债管理和资产配置的战略决策建议。     

基于死亡率风险管理的保险公司最优资本配置研究

本文从死亡率风险管理的角度研究保险公司的最优资本配置问题。应用CBD模型刻画随机死亡率,并假设资本面临的风险来自于随机死亡率。以美国的经验死亡率数据为基础,在偿付能力的约束下探究保险公司在不同产品线上的最优资本配置。通过敏感性分析,考虑保险期限、死亡率改善、缴费方式和随机利率等多种因素对模型结果的影响,对保险公司的最优资本配置有一定的指导意义。     

“偿二代”下满足资本占用最低和收益率目标的结构调整思路

中国保监会关于印发《保险公司偿付能力监管规则（1—17号）》的通知标志着中国保险业监管开始迈入以风险为导向的偿付能力监管时代。中国“偿二代”考虑了资产和负债端的风险,同时又考虑了风险之间的相关性,使得资产配置和业务结构对偿付能力充足率的影响更为复杂和多元,业务结构调整与资产配置之间表现为更强的联动关系,公司流动性、收益性、资本充足率之间的平衡关系不再是直观的简单关系,对公司的经营提出了更大的挑战。鉴于“偿二代”对风险资本计量逻辑的理解,我们试图通过定量的分析探索如何更有效地调整未来保险公司的经营策略。     

资本约束对商业银行资产配置行为的影响——基于175家商业银行数据的经验研究

本文使用1998～2009年我国175家商业银行的资产配置数据,研究了资本监管制度对银行资产配置行为的影响。本文发现,现行的资本监管制度对银行资产配置行为具有重要影响,资本监管制度实施之后,银行依据自身资本水平调整资产结构,资本充足银行持有更多的风险资产,贷款比例较高;而资本不足银行则减持风险资产,贷款比例下降。此外,由于不同规模商业银行面临的融资约束不同,资本水平对资产配置行为的影响存在一定的差异,资本对城市及农村商业银行的约束效应更明显。本文的这些发现为监管当局的资本监管政策提供了经验证据,并提出进行差异化监管的政策建议。     

累积前景理论下的保险公司最优资产配置和风险管理决策--以寿险公司为例北大核心CSSCI

保险公司的资产配置和风险管理决策往往随着内外部经济环境和市场环境的变化而变化,因此,研究保险公司在不确定环境下的最优资产配置和风险管理决策会更贴近现实。为了更好地描述保险公司在不确定环境下的最优决策行为,本文在国内外研究的基础上,以寿险公司为例,首先利用实证方法论证了保险公司具有一种随自身经营状况变化而变化的的风险态度,即不再遵循传统的一致厌恶性风险态度;然后,通过引入累积前景理论(CPT理论),进一步探究了保险公司在不同环境下的风险态度和行为决策是如何变化的,并构建了最优决策模型;最后,基于CPT理论,在最大化保险公司财富效用下,得到保险公司的最优资产配置和风险管理决策结果。结果显示:如果保险公司具有风险厌恶与风险喜好的变化型风险态度,基于EUT效用理论下的最优决策结果得到的效用值远远比不上采用CPT效用理论下的最优决策得到的效用值。     

保险公司投资资产认可标准的设计、风险及挑战——基于偿付能力监管的视角

我国保监会现行偿付能力监管体系对于保险公司资本量的测度与界定,在很大程度上已经不能反映保险公司投资资产所具有的风险,迫切需要形成新一代监管制度。投资资产认可标准的确定是计量偿付能力的基础,本文应用风险价值模型度量了资产的某段时间风险价值,并与投资资产认可标准中风险折价进行对比分析。在此基础上指出投资资产标准认可不当带来的松弛风险、过度约束风险及其他潜在风险。最后本文围绕偿付能力充足率这个核心内容,提出政策建议。     

基于偿付能力的寿险资金战略资产配置

保险资金的战略资产配置是基于公司风险偏好,为满足负债和资本回报要求,对保险资金在大类资产上进行长期规划与分配的过程.本文介绍的寿险资金"战略资产配置三维方法论",是以偿付能力为核心风险偏好,在资本市场长期回报均值回归及Cornish-Fisher展开调整的跨周期宏观经济假设基础上,利用马科维茨模型对公司整体的资产组合进行优化,并以平衡多项业务指标要求的加权打分方式确定战略资产配置方案,然后再确定分账户资产配置,最后进行长期资产负债联动蒙特卡洛动态模拟.通过研究,本文认为应对寿险资金进行跨宏观经济周期的战略配置管理并将偿付能力充足率作为核心风险指标.     

行业组合视角下的银行信贷优化管理——基于中国商业银行的优化模型设计与实证分析

本文在经济下行周期的背景下,从行业组合的视角探讨商业银行如何根据国家政策及自身战略积极布局信贷资产,从被动调控向主动管理转变,实现收益、风险及资本的优化。本文提出两个优化模型——基于最优增长率的均值方差基准模型和专家判断的主动配置模型,通过加入风险相关性、风险容忍度、经济资本等约束,为银行在不同风险偏好下积极配置资产提供依据。本文通过中国商业银行的历史数据,验证上述两个优化模型,发现组合在提升收益、降低风险和提升资本使用效率方面均得到改善,模型具有有效性。     

Short-sale refinancing and price adjustment speed to bad news: Evidence from a quasi-natural experiment in China

Short selling may accelerate stock price adjustment to negative news. However, the literature provides mixed evidence for this prediction. Using short-sale refinancing and a staggered difference-in-differences (DID) model, this paper explores the effect of short selling on stock price adjustment. Our results show that (1) short-sale refinancing improves the speed of stock price adjustment to negative news. This result holds after we control for endogeneity. (2) The positive relationship between short-sale refinancing and stock price adjustment speed is significant in subsamples of stocks with higher earnings management or lower accuracy of analyst forecasts, indicating that firms with more opaque information are more likely to be targeted by short sellers. In subsamples of stocks with a higher ownership concentration or lower ownership by institutional investors, short selling is more likely to increase the speed of stock price adjustment, indicating that ownership structure may influence negative news mining. (3) As short-sale refinancing exacerbates the absorption of bad news by stock prices, it increases crash risk. This study enriches the research on the economic consequences of short selling and provides empirical evidence supporting regulations on short selling in China.

The case for management history

This article defines the case for treating management history as a discrete subject area, although one closely related to business, accounting, labour, and industrial history. It seeks to concentrate on the nature, process, and practice of management as an activity within the organization, and to argue that it is important that modern British managers understand the intellectual and cultural roots of their profession, since without these they will tend to be swayed by short-term management 'fads'. Within the broad topic there are several identifiable sub-areas for potential exploration, including the comparative historical development of management between different countries, management institutions, managerial careers and labour markets, management structures, management skills, and management thought and theory.     

The life and career of John Spence Ogilvy (1805-71), the first chartered accountant to emigrate to Australia

So far as the available evidence allows, this paper examines the life and career of John Spence Ogilvy, foundation member of the Society of Accountants in Edinburgh in 1854, who emigrated to Melbourne in 1856, but did not play a part in the development of an organized accounting profession in Australia. The paper also attempts to explain the gap of thirty-two years between the formation of the first accounting bodies in Edinburgh and Melbourne.

The Impact of IFRS Adoption on an Agribusiness Company's Financial Statements

This fictional case is based on a Canadian public company that produces greenhouse vegetables. Focusing on the differences between International Financial Reporting Standards (IFRS) and Canadian Accounting Standards for Private Enterprises (ASPE), this case provides students an opportunity to (1) apply IFRS in a real world setting; (2) prepare and reconcile financial statements under ASPE and IFRS; (3) analyze the impact of IFRS adoption on key financial ratios; and (4) detect and explain differences in financial statements under ASPE and IFRS through common size analysis.
