我国开放式基金动态资产配置能力研究——基于H-M-FF3模型的检验

基金的动态资产配置能力主要反映为对市场时机的把握能力,本文应用考察市场时机把握能力模型中较为成熟的H-M-FF3模型对我国68只开放式基金的选股能力和择时能力进行实证分析,研究结果表明:我国开放式基金只存在很小程度的选股能力,基本不存在选时能力。

基金的动态资产配置能力主要反映为对市场时机的把握能力,本文应用考察市场时机把握能力模型中较为成熟的H-M-FF3模型对我国68只开放式基金的选股能力和择时能力进行实证分析,研究结果表明:我国开放式基金只存在很小程度的选股能力,基本不存在选时能力。     

我国开放式基金资产动态配置能力研究——基于T-M模型和信息比率的实证分析

基金的动态资产配置能力对于基金公司治理及投资者投资决策都具有重要意义,本文引入T-M模型来衡量市场时机把握能力,信息比率指标（IR）来衡量证券选择能力。在对我国开放式基金在2007至2010年的投资表现进行分析后认为,市场环境会影响到开放式基金的资产动态配置能力,其中,熊市时期对市场时机把握能力的影响较大,振荡时期对证券选择能力的影响较大。     

我国开放式基金的证券选择和市场时机把握能力研究

运用参数检验方法对我国42只股票型开放式基金的证券选择和市场时机把握能力进行了分年度检验,结果发现,开放式基金在2003年具有较强的证券选择能力,但不具备市场时机把握能力,在2004年上半年显示出了一定的市场时机把握能力,却从总体上表现出负向证券选择能力.基于2003年的基金年报分析显示,开放式基金在对未来市场趋势的预测上存在明显的"羊群行为".     

我国证券投资基金选股择时能力实证研究

选择2001—2006年作为样本期,运用T—M模型和H—M模型对我国封闭式基金经理的选股能力和择时能力进行实证研究,实证结果表明我国证券投资基金具有明显的证券选择能力,少量证券投资基金具有明显的时机把握能力,大部分基金时机把握能力不明显。     

开放式基金选择证券以及把握时机能力研究

本文运用T-M模型和H-M模型来分析研究我国开放式证券投资基金的证券选择能力和选择市场时机能力,本文以2003年以前发行的15只开放式基金为研究样本,最终得出结论:我国开放式基金普遍具有较强的选股能力,把握市场时机的能力则有所欠缺.     

开放式基金的资产配置能力研究

本文从战略性和战术性两方面,考察了开放式基金的资产配置能力,对我国30只开放式基金的资产配置能力进行实证检验发现,中国的开放式基金在2004年底至2007年底,尽管取得了骄人业绩,但是其资产配置能力并不很高;研究同时发现,我国证券投资基金主要通过投资组合中证券的调整进行资产配置,而较少依靠对组合中资产的调整来满足资产配置的原则要求。     

我国证券投资基金的资产配置能力研究——基于风险与收益相匹配的视角

本文从风险与收益相匹配的视角，给出了基金经理进行资产配置的原则和理论模型，并据此设计出判断基金资产配置能力高低的标准。对我国54只封闭式基金的资产配置能力进行实证检验发现，中国的封闭式基金大部分具有较高的资产配置能力；研究同时发现，我国证券投资基金主要通过投资组合中证券的调整进行资产配置，而较少依靠对组合中资产的调整来满足资产配置的原则要求。     

基于利率调整下中国证券投资基金绩效评估的实证分析

近年来中国基金市场规模急速扩张业绩表现也时起时落,其中利率调整对基金业绩有着重要的影响。本文从利率调整的角度出发,以中国最早的六支封闭式基金和六支开放式基金从2006年1月1日—2007年6月30日期间的日交易数据为研究对象,利用T—M模型和H—M模型对其进行绩效评估。通过实证分得出利率变动对基金择股和择时能力有较强影响。     

企业年金基金资产结构动态优化研究——基于DCC-GARCH-CVaR模型

资本市场震荡加剧背景下,如何通过资产结构动态调整来增强基金的保值增值能力,是我国企业年金基金投资运营管理中亟需解决的现实技术问题。论文建立DCC-GARCH-CVaR模型刻画资产间动态相关关系和度量投资组合风险,以投资组合风险最小化为目标函数,以期望收益满足最低保证要求为主要约束条件,构建企业年金基金资产结构动态调整模型。结果表明,企业年金基金最优资产结构具有一定的时变特征;资产配置最优权重是各类资产收益风险关系的权衡;资产结构的动态化与多元化是企业年金基金提升保值增值能力的必然选择。     

Almanac of anticipations: The age of affluence—of anticipation—of anxiety—of automation—of discontinuity—of longing—of overkill—of space exploration

With this survey of developments in the futures field since 1945, I.F. Clarke completes his present series for Futures. He makes two major points: that forecasting techniques have become essential tools in the management of change; and that nuclear weapons and ecological problems have added a moral dimension to the study of the future. In the next issue of Futures he will start a new series on the range of future-thinking in the USA, from the expectations of the first settlers to the Star Wars programme.

对基层人民银行科技工作的几点建议

银监会分设后,人民银行将专司货币政策、金融稳定、金融服务三大职能。作为人民银行的分支机构,基层人民银行的工作重心也将从金融监管调整到这三大职能上来。人民银行的科技部门,就要积极运用科技手段,为人民银行履行新的职能发挥“服务、支持、促进、发展”的作用。一、围绕三大职能搭建五大平台经过“六五打基础、七五作准备、八五大发展”几个阶段后,人民银行相继实现了核算电算化、清算网络化和办公信息化。特别是近一两年来,陆续开通了大额支付系统、信贷登记咨询系统、会计四集中系统、金融信息服务网站等系统,人民银行信息化水平又…     

Properties of time-series estimates of degree of leverage measures

Empirical studies suggest that time-series regression estimates of the degrees of operating and financial leverage have a tendency to produce measures less than one. According to ex ante theory, these measures should be greater than one for firms operating above the breakeven point. There have also been suggestions that the biases in these estimates may be attributable to an underlying increase in unit sales. This work presents evidence that these counter-intuitive measures are produced by changes in the firm's operating parameters (unit price, variable cost, fixed cost and interest payments). It further suggests that attempts to control for the underlying change in unit sales substantially increase the volatility of predicted estimates.     

浅议金融机构的举证责任

金融纠纷案件是当事人以存单或进账单、对账单、存款合同、保险单、票据、证券等凭证为主要证据向人民法院提出诉讼的案件,对于不同种类金融纠纷的当事人的举证责任,我国现行的金融法律、法规及司法解释有不同的规定。由于金融机构的特殊法律地位,发生金融纠纷时存在有关当事人将最后偿付风险转移给金融机构承担的主观故意,在客观上会使金融机构难以提供相应的证据来对抗不法债权人的诉讼请求,而导致金融机构败诉。为此,对金融诉讼案件中金融机构的举证责任加以研究具有重要的实践意义。     

Summary of Results of Survey of Seminar Attendees

Abstract

The Society of Actuaries undertook a three-phase research project on mortality improvement in the three NAFTA countries: Canada, Mexico, and the U.S. Phase 1 consisted of a literature review of papers on projecting mortality levels in the future and a study of the trend in mortality improvement during this century. Phase 2 consisted of a discussion of different facets of modeling mortality rates at a seminar attended by 79 experts (actuaries, demographers, economists, and medical researchers) representing different countries. The last session of the seminar consisted of the completion of a survey by the attendees to obtain input for Phase 3, which would analyze the impact of mortality improvement on the social security system of each country. This paper summarizes the results of the survey.

The survey results illustrate the difficulty in forecasting mortality levels, because the effects of many factors that could have significant impact on mortality rates are unknown. This suggests the need for dynamic forecasting, which allows for the possibility of random shocks. A majority of the survey respondents believe that stochastic forecasting models, despite their complexity, have significant potential to add value. Respondents also believe that both historical data and cause-specific mortality forecasts are useful as input and also in validating forecasts of the aggregate levels of mortality. The challenge is to develop more sophisticated forecasting models to produce results that are relatively easy to interpret and to communicate these results to the desired audiences, including the public and policymakers.

The survey results suggest that the aggregate effect of lifestyle changes, medical advances, diseases, catastrophe, and physical environmental changes is an increase in life span. However, there is much uncertainty about the future. Respondents expect that beyond the year 2020 the mean annual rate of reduction in mortality for males age 65 and over will average about 0.58% for Canada, 0.76% for Mexico, and 0.67% for the U.S. The results for the female age 65 and over population are 0.64%, 0.83%, and 0.70%, respectively. The age 65 and over population is expected to see larger percentage reductions in mortality than the 0–14 and 15–64 populations. The reductions in male and female mortality will be ultimately the same, and the mortality levels in the three countries will ultimately converge, although differences may persist for decades.     

The Usefulness of Measures of Consistency of Discretionary Components of Accruals in the Detection of Earnings Management

Abstract:  Prior research has shown the prevalence of measurement error in models used to estimate aggregate discretionary accruals. In these models, the incremental information content of the various components of accruals is ignored. Limited prior research and data gathered from firms under Securities and Exchange Commission (SEC) litigation indicate that managers use either one or more than one component of accruals simultaneously, in a consistent way to manipulate bottom-line earnings in a given direction. I propose two measures that capture the consistency between the discretionary components of accruals and test their significance in earnings management (EM) detection in firms that have artificially added accrual manipulation and firms that were targeted by the SEC for accrual manipulation. There is evidence that this information is incrementally useful in detecting EM. This finding paves the way for improvements in the discretionary accruals measure by including consistency information from the components of aggregate accruals.     

Separation of Unit of Account from Medium of Exchange

The separation of a unit of account (UoA) from a medium of exchange (MoE) in the commodity–money system is investigated by considering explicitly a seller's choice of UoA in terms of either an MoE or a unit of metal weight. If the likelihood of debasement of an MoE and its rate are high enough, the price is posted in terms of a unit of metal weight rather than an MoE. Interestingly, this MoE–UoA separated equilibrium yields the flexible nominal price, whereas an MoE–UoA integrated equilibrium yields the sticky one. This implies the nominal price rigidity in the fiat‐money system where MoE and UoA are integrated.
