Distinctive characteristics of entities with an internal audit department and the association of the quality of such departments with errors*

Abstract. This research identifies those characteristics that could potentially influence a choice to create an internal audit department and tests via discriminant analysis to evaluate whether such attributes significantly distinguish between companies with and without an internal audit department. In addition, qualitative characteristics of such departments are described, as is the association of such traits with errors and the overall control environment. A sample of 260 companies is examined. Companies with internal audit departments are observed to be significantly larger, more highly regulated, more competitive, more profitable, more liquid, more conservative in accounting policies, more competent in their management and accounting personnel, and subject to better management controls. Key discriminant variables are the degree of regulation, decentralization, size, the duration of association with present auditors, the existence of an audit committee, EDP control, and pressures by external parties on management to achieve budgetary goals. Qualitative attributes of internal audit are systematically associated with the overall quality of the control environment, as well as errors. The most important attribute appears to be the independence of internal audit in terms of the propriety of the reporting level. An advantage of internal auditing is that external auditors report a 10 percent reduction in the number of hours incurred and greater flexibility appears to exist in the proportion of work performed in off-peak periods. Résumé. Les auteurs dressent l'inventaire des caractéristiques susceptibles d'influer sur le choix de créer un service de vérification interne et soumettent ces attributs à des tests, par voie d'analyse discriminante, afin de déterminer s'ils permettent d'établir une distinction claire entre les entreprises ayant et n'ayant pas de service de vérification interne. De plus, ils décrivent les caractéristiques qualitatives de ces services, de même que l'association de ces carctéristiques aux erreurs et au contexte global du contrôle. Les auteurs procèdent à l'examen d'un échantillon de 260 entreprises. L'étude révèle que les entreprises possédant des services de vérification interne sont beaucoup plus souvent des entreprises de grande taille, faisant l'objet d'une réglementation plus rigoureuse, plus concurrentielles, plus rentables, ayant davantage de liquidités, plus prudentes dans leurs conventions compatables, possédant une équipe de gestion et un personnel comptable plus compétents et soumises à de meilleurs contrôles de gestion. Les principales variables discriminantes sont le degré de réglementation, la décentralisation, la taille, la durée de l'association avec les vérificateurs actuels, l'existence d'un comité de vérification, le contrôle dans un cadre informatique et les pressions exercées par les tiers sur la direction pour l'atteinte des objectifs budgétaires. Les attributs qualitatifs de la vérification interne sont systématiquement asociés à la qualité globale du cadre de contrôle, de même qu'aux erreurs. L'attribut le plus important semble être le degré d'autonomie du service de vérification interne, c'est-à-dire le caractère approprié de ses liens hiérarchiques. La vérification interne comporte un avantage: les vérificateurs externes font état d'une réduction de 10 pour cent dans le nombre d'heures consacrées à la vérification, et il semble exister une plus grande souplesse dans la proportion du travail de vérification effectué en dehors des périodes de pointe.     

Analyzing Cost Differences in Life Insurance

Several indexes for comparing the cost of life insurance policies are currently available. A variety of criticisms of these indexes has been offered. This paper identifies an additional problem: consumers may lack confidence in index values because they do not reconcile with data about company performance (e.g., lapse ratios, returns on invested assets). Analysis results suggest that policy costs are as much a function of actuarial manipulation for marketing advantage as of commonly cited textbook factors (mortality, interest, expenses) and competitive factors (lapse ratio, average policy size).     

战略风险评估7步走

“对大多数公司而言,董事会倾注注意力和时间的重心是理解战略及关联风险并提供指导……以及对高管实施战略和风险管理两方面的业绩进行监管。”由美国全国公司董事协会（NACD）出版的《加强美国上市公司监管的关键议定原则》中如是表示。     

An Investigation of Transactions Data for NYSE Stocks

Using transactions data, the behavior of returns and characteristics of trades at the micro level is examined. A minute-by-minute market return series is formed and tested for normality and autocorrelation. Evidence of differences in return distributions is found among overnight trades, trades during the first 30 minutes following the market opening, trades at the close, and trades during the remainder of the day. The latter distribution is found to be normal. Unusually high returns and standard deviations of returns are found at the beginning and the end of the trading day. When the beginning-and end-of-the-day effects are omitted, autocorrelation in the market return series is reduced substantially. A number of patterns in trading are reported.     

The 52-Week High and Momentum Investing

When coupled with a stock's current price, a readily available piece of information—the 52‐week high price–explains a large portion of the profits from momentum investing. Nearness to the 52‐week high dominates and improves upon the forecasting power of past returns (both individual and industry returns) for future returns. Future returns forecast using the 52‐week high do not reverse in the long run. These results indicate that short‐term momentum and long‐term reversals are largely separate phenomena, which presents a challenge to current theory that models these aspects of security returns as integrated components of the market's response to news.     

Inflation and Stock Market Returns:Some Australian Evidence*

This paper analyzes the relationship between Australian stock returns and inflation over the period 1965-79. The effects of inflation in a ‘rational investor’ valuation framework are discussed. Empirical tests suggest that nominal stock returns and inflation are related in a significantly negative fashion, implying that stocks have been extremely poor inflationary hedges for the investor over the period. In addition, Granger-Sims tests of causality indicate a mainly unidirectional relationship between inflation and stock returns, with price level charges leading the equity index in time.     

STADIUM CONSTRUCTION AND MINOR LEAGUE BASEBALL ATTENDANCE

The established literature shows that new stadium construction for major league baseball (MLB) teams can increase attendance, but there are limited studies at the minor league level. We use a data set encompassing all A, AA, and AAA minor league baseball teams from 1992 to 2006 to estimate the impact of stadium construction on minor league attendance. This data set includes almost 200 teams, over half of which constructed a new stadium during the 15‐year observation period. Over a 10‐year period our results show that new stadiums increase attendance by 1.2 million fans at the AAA level, 0.4 million at the AA and high A level, and 0.2 million at short season low A. A cost benefit analysis suggests that increased ticket sales do not offset the stadium costs, in line with previous works on MLB. (JEL H0, L83)     

Forward Markets,Stock Markets,and the Theory of the Firm

This paper models a competitive financial market economy in which there are forward markets as well as stock and bond markets. Although there are separation theorems in the stock and forward markets literatures, this analysis shows that neither separation theorem survives in this integrated financial market economy. Next, the analysis shows that the separation results hold and are equivalent if the manager has an appropriate compensation package. Then the model is modified to allow for depreciation charges and tax credits. A positive theory of hedging is developed that shows that the corporation can preserve deductions and credits by hedging and so increase corporate value.
