美国保险资金运用的分析及借鉴

美国是全世界最重要的保险市场,其保险资金运用对我国具有很好的借鉴意义。美国寿险资金和非寿险资金因为来源不同,所以投向也不相同。美国保险资金运用呈现以下特点:广泛的保险资金运用渠道,高稳定性的保险投资追求,多重的保险资金管理模式,协调的保险投资监管方式。美国保险资金运用为我国带来如下启示:要与金融市场环境和监管制度相适应、要实现资产负债匹配管理、要注重加强战略性资产配置、要充分发挥资产管理公司的作用。     

基于CDaR的保险资金运用风险管理模型

基于对国内保险资金投资风险测量的主流方法VaR和CVaR模型的缺陷进行分析后,本文提出将新的风险度量方法CDaR模型引入到国内保险资金的投资风险管理实践,结合我国保险资金投资管理条例中的相关投资风险约束条件和国内金融市场的实际情况,并考虑到保险资金的资产负债匹配管理要求,提出了有投资约束条件下的保险资金风险管理拓展模型.     

美国保险公司的资产负债管理及对我国的启示

资产负债匹配是保险资金投资管理的核心。保险投资的方式与比例应考虑到不同的资产和负债在数额、期限、性质、成本收益双边形成对称并相匹配。保险投资中的资产负债匹配管理技术主要有现金流测试、现金流匹配、免疫管理、动态金融分析和货币匹配等。     

保险公司的资产负债匹配管理

由于保险资金的鲜明负债特性,保险投资资产分配中必须充分考虑不同保险资金的负债特征的要求,科学的资产负债匹配模式及有效实施是保险公司有效控制风险、实现投资价值最大化的重要保证,资产负债匹配是保险资金投资运作的核心。     

论保险公司的资产负债匹配管理

保险公司经营管理之核心工作就是资产负债匹配管理,对资产和负债进行灵活匹配、科学运用资产负债管理策略,可以降低风险、提高盈利和市场竞争力。本文论述了保险公司资产负债管理及其匹配管理的重要意义及其紧迫性,研究了我国保险公司资产负债管理的发展现状与差异、分析了资产负债管理的行业环境,最后提出了选择保险公司资产负债匹配管理的相关策略。

East and west and north and south : A preliminary model

The Brandt report and other proposals for a new North-South world order continue to be the focus of lively debate, yet it is often argued that little concrete has emerged from their recommendations. A major reason for this, the author argues, is that the East-West conflict component is not sufficiently taken into consideration-East-West tensions are a severe constraint on and a determining factor of North-South relations. Using influence diagrams, the author develops a flexible framework for discussion and assessment of N/S-E/W relations.     

Amplification and asymmetry in crashes and frenzies

We often observe disproportionate reactions to tangible information in large stock price movements. Moreover these movements feature an asymmetry: the number of crashes is more than that of frenzies in the S&P 500 index. This paper offers an explanation for these two characteristics of large movements in which hedging (portfolio insurance) causes amplified price reactions to news and liquidity shocks as well as an asymmetry biased towards crashes. Risk aversion of traders is shown to be essential for the asymmetry of price movements. Also, we show that differential information can enhance both amplification and asymmetry delivered by hedging. This paper is based on part of my Ph.D. thesis submitted to the University of Minnesota. I am grateful to Andy McLennan and Jan Werner for their valuable advice and unwavering support. Also, I would like thank Mehmet Barlo, Michele Boldrin, Partha Chatterjee, Mehmet Ozhabes, Dimitrios Tsomocos and seminar participants at the University of Minnesota, the MEA and the MFA Meetings in St Louis for helpful comments. Comments on a previous draft by an anonymous referee greatly improved the presentation of this paper. Financial support from William W. Stout Fellowship is gratefully acknowledged.

Noise trading and prime and score premiums

This paper documents that a common element drives the time-series variation of the premium pricing of Primes and Scores. I argue that this common element is noise trading. The noise trading model of Delong, Shleifer, Summers and Waldmann (1990) predicts that returns on assets that are predominantly traded by noise traders will be correlated, since the misperceptions of noise traders are cross-sectionally correlated. Consistent with the noise trading hypothesis, changes in the average premium of Primes and Scores, which are predominantly traded by individual investors, are correlated with both changes in average discounts of closed-end funds and small firms returns. These empirical facts provide additional evidence that noise traders can affect security prices.     

Debt and Taxes and Uncertainty

With a graduated personal tax schedule, Miller showed that there could be an equilibrium debt supply for the corporate sector as a whole. In the presence of uncertainty there is also a unique debt/equity ratio for each individual firm, and this ratio is related to the firm's operational risk characteristics. However, if firms merge and spin off in response to tax incentives, the identity of firms is ambiguous and only the corporate sector is a meaningful construct. These arguments are developed in both discrete and continuous models that employ extensions of the arbitrage-free pricing theory.

Stock and Bond Liquidity and its Effect on Prices and Financial Policies

An asset is liquid if it can be traded at the prevailing market price quickly and at low cost. We show that in addition to risk, liquidity affects asset prices and returns. Theories of asset pricing suggest that the expected return of an asset is increasing in its risk, because risk-averse investors require compensation for bearing more risk. Because investors are also averse to the costs of illiquidity and want to be compensated for bearing them, asset returns are increasing in illiquidity. Thus, asset prices should depend on two asset characteristics: risk and liquidity. This paper surveys research on the effects of liquidity on asset prices and returns, showing that liquidity is an important factor in capital asset pricing.     

Aggressive CEOs and bank mergers and acquisitions

The U.S. banking industry has seen waves of mergers since the 1980s. Despite a significant body of research on the determinants of these waves, there are few studies of how CEOs influence banks’ mergers and acquisitions (M&As). This paper studies the effect of CEO aggressiveness on bank M&As. We construct a new measure of bank CEO aggressiveness based on CEOs’ ancestral countries of origin and data on inter-country wars. We find that aggressive CEOs are more likely to acquire other banks. Moreover, the impact of CEO aggressiveness on bank M&A decisions is more pronounced when the CEOs are from larger and more profitable banks, when CEOs have a longer tenure, and when CEOs’ ancestral country of origin has a more masculine culture. Moreover, we show that aggressive CEOs are more likely to make acquisitions when CEOs possess more cultural maintenance, which captures the extent to which CEOs retain their original cultural values and beliefs. Finally, we document positive short-term stock market reactions to bank M&As initiated by aggressive CEOs.     

Cloud-based client accounting and small and medium accounting practices: Adoption and impact

Cloud accounting represents a major disruptive technology for the accounting industry. This qualitative study used semi-structured interviews to collect data from eight small and medium accounting practices (SMPs) to test a preliminary model of the determinants and impact of cloud-based client accounting adoption by SMPs. Accordingly, the SMP was the unit of analysis. The complex triadic relationship between SMPs, their clients and cloud accounting provider necessitated an interorganisational perspective. Four factors contributed to SMPs’ adoption decisions: perceived benefits of cloud-based client accounting, perceived benefits of partner programs, organisational readiness (IT sophistication and client readiness), and external pressure (client and competitive pressures). Subsequent to adoption, SMPs experienced a decline in the levels of traditional (statutory) services provided. However, most noted increases in income from business advisory. All firms were at least as well off after adoption. Improvements in client relationships and the perceived value of accountants’ services were also noted. An adoption/impact typology predicted and found positive impacts for cloud initiators, in particular. The findings have implications for owners of SMPs, their SME clients, and for accounting professional bodies.
