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.

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.     

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.     

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.
