声誉机制与证券分析师的利益冲突行为研究

理论界关于声誉机制对证券分析师利益冲突行为的影响存在两种截然不同的观点,本文通过构建证券分析师不同情况下的收益矩阵,求解其最大化的期望收益,得出了声誉机制会引发证券分析师的利益冲突行为,而且证券分析师是否选择跟风主要取决于不同情况下的收益的结论.本文认为,可通过建立声誉回报机制来影响证券分析师的收益,促使证券分析师发布独立且公正的投资建议,以消除证券分析师的利益冲突行为.     

中美证券分析师"公司研究报告"之比较

我国证券分析师研究报告与国外相比无论是格式和内容都有一定差距，为提高我国证券分析师的水平，本文将“公司研究报告”进行了中美比较，分析了两者之间的重大差异，指出了我国证券分析师研究报告中存在的不足，以期为我国证券分析师改进其研究报告提供参考。     

行为金融与证券投资分析

行为金融学是现代金融理论发展的新突破.行为金融对于证券投资的指导意义在于对传统金融学理论"理性人"假说的突破,由此可以解释金融市场上出现的各种"异象",投资者的行为思维受到社会、环境、心理等因素的影响而呈现非理性.基于对投资者行为金融表现的研究,投资者应建立起应对于自身非理性行为心态的证券投资分析方法.     

我国证券分析师特征与预测准度之间的经验分析

基于2002—2009年的大样本证券分析师公司年盈余预测数据,使用相对预测分析方法,在控制了其他预测影响因素之后,发现我国证券分析师特征显著影响他们的盈余预测准度。具体而言,我国证券分析师跟进公司的时间越长就越有经验,盈余预测就会越准;证券分析师跟进的公司数目越多和行业数目越多,预测研究的组合任务就越复杂,就不能有效发挥专业化优势,盈余预测就会越不准。不过,与假设预期不一致的是,我国证券分析师所在的研究机构规模越大,并没有发挥像国外大型研究机构所具有的资源优势,证券分析师盈余预测反倒越不准确。     

中国证券分析师独立性问题研究

本文利用分析师利益最大化模型全面分析了证券分析师面临的各种利益关系对其发布的研究报告质量的影响,并收集了从2007年至2010年所有证券分析师发布的盈余预测与股票评级作为样本对研究假设展开实证研究.     

国外证券分析师盈利预测实证研究综述

在对投资决策、资本成本、公司评估、盈余与股价的关系等进行探讨的文献中，分析师的盈利预测被广泛地用作盈利预期的代理变量，成为理论研究的一项基础。本文对国外证券分析师盈利预测的实证研究文献进行了综述，分析、比较了盈利预测业绩衡量标准、各衡量模型的优劣、乐观偏差、预测修正、意见分歧以及分析师跟进等理论。     

证券分析师的羊群行为研究

羊群行为是目前越来越被关注的一种心理现象，它的出现对众多研究领域都产生了深远的影响。在经济学领域，人们在群体的压力下往往放弃自己原来的主见而追随大流，这种从众（羊群）的心理对传统经济学“理性的经济人”假说构成了极大挑战。本文以证券市场上证券分析师中的羊群行为为研究对象，并针对羊群行为无法捕捉、难以量化的研究难点。提出羊群行为与分析师个性特征之间的量化回归模型，对深入探讨在证券分析师群体中羊群行为的成因以及证券分析师的羊群或冒险的预测对证券市场信息传递效率的作用和市场有效性程度的提高具有重要的理论和实践意义。

承销商分析师与非承销商分析师利益冲突比较研究

基于证券分析师首次发表的关于2006~2008年A股市场IPO股票的研究报告数据,运用非参数检验与多元回归分析方法,对我国证券分析师利益冲突行为进行实证分析。研究结果表明,承销商分析师与非承销商分析师均存在乐观倾向,而且承销商分析师的投资评级更为乐观;市场对于承销商分析师与非承销商分析师关注股票的反应并无显著差异,表明我国证券市场投资者并没有认识到分析师的利益冲突行为。     

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…     

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.

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.     

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.     

银行软件项目外包管理分析

一、引言随着国民经济的不断发展,银行业务与外部企业的联系越来越密切。银行正逐步成为现代经济活动的中心,作为数据处理核心的银行业务应用也越来越大型化、越来越复杂化,因此许多银行也把软件项目逐步由原来的自主开发转变为与公司合作的方式,或直接外包开发的方式,银行本身的技术人员也逐步由开发转向项目管理。二、项目外包的分类银行项目的外包有以下几种情况:①部分子系统外包,有时由于银行的软件项目太大,单靠银行自身的开发力量基本无法在预定的时间内完成项目,只好把相对独立的部分外包;②直接购买软件公司的成熟产品,有些金融软…     

银行管理信息平台建设发展的思考

一、目前国内银行IT发展现状及面临的问题 银行数据集中工作的完成,标志着银行的业务由电子化建设阶段转入信息化建设阶段.一方面银行数据的集中提供了丰富全面的基础数据,面对日益庞大的数据源,如何将数字转化为对银行有用的信息,并从中发现知识,为银行的经营决策提供支持,是摆在银行IT人员面前的一个亟待解决的问题.另一方面用户对银行信息的需求日益增长,如果银行没有一套完整、实用的信息管理系统,将对业务发展非常不利.南京爱立信公司倒戈花旗银行事件曾经轰动一时,其中一个重要原因就是中国本地银行不能满足爱立信全球总部对南京爱立信公司的要求:每周财务上报和每天贷款限额管理.这一事件为中国商业银行的未来发展敲响了警钟,如果不加快管理信息系统的开发,迅速提升业务管理水平,类似的事件还会接连不断地发生,并最终导致国内商业银行在同国外商业银行的竞争中全面溃败.     

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.
