资产配置对基金收益影响程度的定量分析

资产配置是证券投资决策的首要环节,它可分为战略性资产配置及包括选时和选股在内的战术性资产配置.资产配置不但影响了基金业绩沿时间的变化,还对基金之间的业绩差异具有较高的解释程度.本文利用中国的市场数据,度量了资产配置对基金收益的影响程度.     

社会互动与家庭金融资产配置

运用中国家庭金融调查(CHFS)数据,研究社会互动与家庭金融资产配置之间的关系。研究发现,适当增强社会互动会促进家庭更多地参与风险金融市场,增加投资风险资产的比例,提高金融资产的分散化程度,优化资产的配置效率。但当社会互动达到一定程度后,过度的社会互动则会抑制家庭参与风险市场,减少风险资产的投资比重,降低金融资产的分散化程度以及资产配置的有效性。因此,家庭需要建立适度而高质量的社会互动,这有助于家庭获得更多的外部资源,缓解信息不对称,降低交易成本,从而优化家庭金融资产配置。     

New Evidence on Optimal Asset Allocation

Brocato and Steed (1998) showed that portfolio rebalancing based on NBER business cycle turning points substantially improves in‐sample Markowitz efficiency. In a similar vein, we investigate potential improvements from rebalancing based on turning points in the monetary cycle. We find that the monetary cycle has greater influence than the business cycle on the variance/covariance structure of multiple asset classes. Furthermore, we find substantial improvements in in‐sample efficiency beyond a buy‐and‐hold strategy and the business‐cycle approach. Importantly, our indicator of monetary cycle turning points has a practical advantage over NBER business cycle turning points, in that it relies only on ex ante information. In out‐of‐sample tests, we continue to find superior portfolio performance after transactions costs using the monetary cycle to time portfolio rebalancing.     

随机规划模型与商业银行资产的最优配置

有关商业银行资产负债管理模型的研究表明,基于多阶段带简单补偿的资产负债随机模型适合现阶段中国商业银行的资产负债管理问题。本文建立了三大国有上市商业银行的简化资产负债管理模型,运用遗传算法进行运算求解。模型结果能反映商业银行资产配置的基本变化趋势;贷款配置比例始终大于债券投资比例,表明银行仍然立足于传统信贷业务;三大商业银行的最优资产配置略有差异。考虑到商业银行资产收益率以及存款负债流的不确定性,实证结果表明该模型对实际管理决策具有现实指导意义。     

资本约束下保险公司最优大类资产配置模型研究

中国第二代偿付能力监管制度体系(以下简称“偿二代”)执行以后,投资风险直接体现在资本要求上,资本充足率成为保险公司投资决策的重要约束。在此背景下,保险公司有必要建立整体经济资本预算框架,通过提高各类资产的边际资本回报率,提升公司股东价值。本文通过理论研究证明资本约束下保险公司最优大类资产配置的路径首先是进行负债风险匹配资产的管理,其次才是追求盈余资产收益最大化,同时,本文创新性提出了三阶段的数值求解方法,填补了国内文献以及保险公司实践中难以前置化资本约束得到大类资产配置数值解的研究空白。     

An Examination of ERR and Asset Allocation in Public Pension Plans

In this paper, we examine the usefulness of expected rates of return (ERR) for public pension plans. Specifically, we test the correlation between the expected rate of return on plan assets and asset allocation. We also examine the predictive power of ERR on the actual returns of the pension assets. We find that the correlation between expected return and the percentage of assets that are equity securities is relatively weak. Further, we find that the percentage of assets that are equity securities is a much better predictor of actual returns than the disclosed expected return in public pension plans. These results provide evidence to support SFAS No. 87 , which requires the disclosure of plan assets and against recently promulgated SFAS No. 132 , which eliminates this disclosure requirement. The evidence also supports GASB 25'sStatement of Net Plan Assets .     

Asset Allocation and Selectivity of Asian Mutual Funds During Financial Crisis

This paper evaluates the ability of US-based Asian mutual fund managers in coping with the 1997 Asian financial crisis. We find that the actively managed mutual funds under-perform with respect to the market portfolio by 1.71% in average monthly return. Such poor performance is caused by fund managers' relative weakness in country selection as well as in stock picking. Fund managers are also found to be more skillful in picking the correct market when the market is going up than going down. Our results are consistent with the literature that asset allocation in Asian mutual funds is a dominating factor relative to selectivity in explaining fund returns during the financial crisis. In addition, there exists a negative relation between asset allocation ability and selectivity of fund managers.     

Asset Allocation Via The Conditional First Exit Time or How To Avoid Outliving Your Money

The risk of outliving your money (or shortfall) with low risk, low return investments is very often more serious than the risk of losing money on high risk investments, until quite late in life. A stochastic process model incorporating mortality tables for men and women of retirement age, random rates of return and fixed initial wealth and desired level of consumption provides the analytical tool. A simulation using Canadian mortality tables and rates of return shows that almost all retirees should invest some of their wealth in equity, and for many the optimal allocation is 70–100% equity. The risk of shortfall is surprisingly high for a reasonable range of values of the variables, especially for an allocation of 100% in treasury bills. Women face much greater risk of shortfall than men. The analytical model also permits calculation of the distribution of the bequest and hence allows an individual to trade off changes in shortfall risk against changes in the expected bequest to the heirs.     

中国居民资产配置趋势及商业银行对策

从近年来中国居民金融资产变化情况来看,在金融资产总量急剧增加的同时,资产结构也由原来单一的银行资产向多元化方向发展,但储蓄存款仍居主导地位,人均居民金融资产水平也较低。后危机时期居民金融资产总量增长空间仍然较大,资产多元化趋势将更加明显,这意味着储蓄存款将持续减少,而证券、基金、保险、信托、银行理财产品等新型金融产品的投资将日益扩大,居民资产配置以储蓄为主的格局仍将持续较长时间。这为商业银行发展带来两个机遇:一是为商业银行实现经营转型带来了发展机遇;二是为商业银行个人资产管理业务带来了发展机遇。     

The Performance,Asset Allocation,and Investment Style of International Equity Managers

This paper evaluates the performance of 114 international equity managers over the January 1988–December 1997 period. Performance tests are conducted using Sharpe (1966) and Jensen (1968) performance methodologies. The managers are divided into mutual fund (n=54) and separately managed fund (n=60) investment management categories. Each management category is further divided by foreign and world (global) investment objectives. Three major findings are reported. First, international equity managers, on average, were unable to outperform the MSCI World market proxy during the sample period. However, world managers did perform better than their foreign counterparts. Second, geographic asset allocation and equity style allocation decisions enhanced the performance of international managers during the sample period. Third, separately managed funds outperformed mutual funds during the period studied when mutual fund returns are measured net of management fees. The apparent managed performance advantage abates, however, when mutual fund returns are adjusted to include management fees. Thus, we find no significant difference in the performance of the management categories when returns are measured gross of fees.     

企业金融资产配置与融资约束的缓解机制:基于流动性管理的分析

企业进行金融资产配置,一方面能够为企业提供流动性,缓解融资约束;另一方面也因投机动机而占用企业流动性资源,加剧融资约束,对实体投资造成挤压。这是形成企业金融化的"投资挤出效应"和"蓄水池效应"两种现象并存的内在机制。为衡量这种内在机制,本文使用2007—2018年我国上市公司样本,对金融资产配置的流动性管理效应展开分析。结果显示:非金融企业的金融收益会推动超额现金的持有,通过超额现金的中介效应引致了融资约束程度的缓解;而企业持有金融资产行为则产生相反的效应。进一步研究发现,在典型的公司治理机制中,无论是外部股东的投票机制,还是来自内部的代理成本与高管持股机制,都在一定程度上推动了金融资产配置产生的流动性效应。     

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。     

融资流动性对商业银行资产配置行为的动态影响

使用14家上市银行2007~2013年季度数据建立面板向量自回归(PVAR)模型,运用脉冲响应函数分析融资流动性对银行资产配置行为的动态影响。研究结果表明：存款成本和银行间融资成本的上升,会激励银行增加风险资产,减少流动性储备,不利于银行防范结构性流动性风险;存款流失会削弱银行贷款扩张的动力,提升流动性偏好;同业融资依赖性的上升短期内可以改善银行资产的流动性,长期则会加大资金借短贷长的问题,为流动性危机埋下隐患。     

Determinants of Real Estate Asset Allocations in Private and Public Pension Plans

Numerous studies have examined the factors associated with allocation of corporate and government pension-plan assets. Yet to date there has been no attempt to identify the sponsor-related conditions that affect the percentage of U.S. private and public pension-fund assets invested in real estate. The purpose of this article is to examine various asset-and liability-matching hypotheses regarding pension-plan asset allocations. Models are specified for both corporate and government defined-benefit plans that relate the characteristics of each plan to the percentage allocated to real estate investments. Our results confirm the existence of a significant size effect for both corporate and government pension plans, although we find mean levels of real estate allocation to be much lower than those suggested in previous real estate allocation studies. The article, however, contains some anomalous findings. In particular, our findings suggest that pension-plan sponsors do not hedge their real estate risk. We also find that pension-plan sponsors do not invest in real estate, as theory might suggest, to minimize the noise level in their pension liabilities.     

Futures Commitments and Commodity Price Jumps

We examine the relationship between the commitments of three of the largest groups of futures traders and the abnormal price movements in five agricultural commodities. The general evidence suggests that the commitments of futures traders have been increasing over time, whereas the frequency of price jumps have not. Regression results indicate a negative relationship between price jumps and the commitments of speculators and small traders. There is also evidence of a negative relationship between the number of speculators and cash market volatility, consistent with a host of speculation-based theories.     

International Asset Excess Returns and Multivariate Conditional Volatilities

This paper constructs a multivariate model in relating multi-asset excess returns to their conditional variances. Applying weekly data to investigate the foreign-exchange risk premium, the evidence from a multivariate GARCH model shows that the foreign-exchange excess returns are significantly correlated with economic fundamentals such as the real interest-rate differential, long-short interest-rate spread differential, and equity-premium differential. The evidence also suggests that foreign-exchange excess returns are not independent of the conditional variances of these fundamental variables, supporting the time-varying risk-premium hypothesis.     

The Variation of Economic Risk Premiums in Real Estate Returns

We examine the predictable components of returns on stocks, bonds, and real estate investment trusts (REITs). We employ a multiple-beta asset pricing model and find that there are varying degrees of predictability among stocks, bonds, and REITs. Furthermore, we find that most of the predictability of returns is associated with the economic variables employed in the asset pricing model. The stock market risk premium is highly important in capturing the predictable variation in stock portfolios, and the bond market risk premiums (term and risk structure of interest rates) are important in capturing the predictable variation in bond portfolios. For REITs, however, both the stock and bond market risk premiums capture the predictable variation in returns. REITs have comparable return predictability to stock portfolios. We conclude that there is an important economic risk premium for REITs that are not captured by traditional multiple-beta asset pricing models.
