中国IPO抑价现象研究

各国股票市场都存在一定程度的IPO抑价现象,而新股发行市场化之前我国IPO抑价现象尤其严重,新股发行询价制度推行以来有所缓解。本文选取06年至11年的新股发行数据对IPO抑价现象的原因进行探究,发现市场因素、中签率、发行价格、发行市盈率、首日换手率对IPO抑价现象有较强的解释力。

信息不对称与承销商能力对IPO抑价的影响——基于创业板上市公司的研究

本文选取了自创业板开板以来至2012年2月29日所有创业板IPO公司作为研究对象,研究信息不对称和承销商能力对IPO抑价的影响.结果表明,法人配售比例、发行市盈率和首日换手率与抑价呈正相关关系,中签率成反比;上市等待日期和承销家数与抑价呈正比,融资金额呈反比;法人配售比例对IPO抑价的影响最大;信息公开不充分、承销商声誉高低及其引起的投机情绪对IPO抑价有很大程度的影响.建议完善创业板市场操作,建立良好的信息披露机制,引导投资者理性投资,勿盲目投机.     

投资者情绪对IPO抑价影响研究——来自深圳中小板、创业板市场的经验证据

本文运用分位数回归方法研究了我国2009年6月新股发行改革后深圳中小板、创业板市场投资者情绪对IPO抑价的影响,结果显示,新股发行改革后我国IPO抑价率依然很高;首日换手率、中签率、发行市盈率这些反映投资者情绪的指标是影响我国深圳中小板、创业板市场IPO抑价的重要因素,通过分位数回归发现我国不同分位点上IPO抑价影响因素有很大的不同。分位数回归方法能够更全面、准确地分析不同抑价程度下IPO抑价的影响因素。     

中国创业板IPO抑价影响因素实证研究

本文首先提出创业板新股发行的高市盈率、高抑价率的现象,在此基础上,对国内外学者对于IPO抑价提出的相关理论与研究现状进行了分类整理和总结。然后,结合我国创业板的实际情况,选择了上市首日换手率、中签率、净资产收益率、管理层持股比例等在内的10个变量作为衡量IPO抑价的指标。为了能有效衡量IPO抑价,本文选择了从2009年10月30日至2012年12月29日上市的356支股票作为样本数据,建立线性回归模型,运用逐步回归法以及加权最小二乘法进行实证分析,从而验证当前新股发行抑价理论对我国创业板的适用性。     

IPO抑价影响因素实证分析

本文主要研究导致IPO抑价的影响因素,并根据现有研究理论和中国股票市场的实际情况,选取了可能影响抑价的6个解释变量,即中签率、发行价格、发行市盈率、交易日换手率、上市等待日期、资产负债率,进行了多元回归分析,得出我国IPO抑价程度与六个解释变量的相关程度,分析了导致IPO抑价率较高的原因,在此基础上从提高投资者水平、增加新股供给量、完善发行制度和完善监管制度等方面提出政策性建议.     

基于投资者情绪的我国创业板IPO抑价实证研究

本文以2 009年至2 011年以来在创业板上市的281家公司为样本,对创业板市场的IPO抑价进行实证研究,即以IPO抑价率为因变量,以反映投资者情绪的市盈率、新股中签率、上市首日换手率等指标为自变量进行多元逐步回归分析.研究结果表明,对抑价率影响最为显著的是上市首日换手率,其次是新股中签率,而发行价和市盈率等其他变量对于IPO抑价率都没有显著影响.     

投资者情绪、信息不对称对IPO抑价的影响——基于深圳创业板的实证研究

我国创业板干2009年10月23日在深圳证券交易所正式开板,标志着我国离建设多层次资本市场的目标又进了一步.正如其他板块,创业板也面临着IPO抑价的问题.首批上市的28家创业板公司在上市首日股价大幅上扬,首日平均涨幅达到106％.本文试图从投资者情绪和非对称信息两个角度来对创业板IPO抑价问题进行分析.实证结果显示IPO抑价与投资者非理性以及非对称信息相关,特别是投资者非理性.IPO抑价率与首日换手率正相关,而与中签率负相关.表明行为金融学是是未来研究IPO抑价问题的方向.当然,投资者情绪以及非对称信息与新股供求关系以及发行机制密切相关.最后基于本文的实证结果给出了一些政策建议.     

我国IPO高超募与高抑价关系模型研究

基于投资者行为的研究视角,构建IPO超募与抑价关系模型,探讨IPO抑价和IPO超募的传导机理。通过研究表明:IPO抑价UP与散户投资者对新股价值评估正相关,与机构投资者对新股价值评估负相关。IPO抑价UP与新股超募负相关,且IPO抑价和新股超募可以同时存在。最后,通过数值分析模拟证明结论。     

我国投资银行声誉假说的实证研究

国外很多的学者对由知名的投资银行和普通的投资银行所承销的新股的不同市场表现进行了研究,发现知名投资银行承销的新股发行抑价程度要低于普通投资银行,即所谓的投资银行声誉假说.本文选取1996年1月至2003年3月在沪市发行上市的A股为研究样本,对投资银行声誉假说在我国新股发行中的适用性进行实证研究,实证结果显示这一假说在我国并不成立.     

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.     

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.     

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…
