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.     

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。     

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.     

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.     

The effect of phosphate detergent bans on consumer clothing expenditures

Metropolitan sales data from the 1977 Census of Retail Trade were analysed to test whether phosphate detergent bans increased consumer expenditure on clothing: positive effects were found for men's clothing and domestic fabrics (sheets and towels). In areas with medium water hardness the average annual cost in 1977 equalled $11·08 per household. For 1984, the equivalent cost was $14·17 per household. These results are consistent with laboratory studies that show decreased detergency associated with non-phosphate detergents and increased fabric wear associated with carbonate-built detergents, the principle substitute for phosphate detergents. The bans impose the largest cost on hard water areas. In both ban and non-ban areas in 1977 higher laundering costs were associated with higher water hardness. Analysis of 1972 data indicated that water hardness did not affect clothing expenditures significantly when detergents contained large amounts of phosphates.     

Welfare Loss from Inaccurate Information: An Economic Model with Application to Food Labels

This study develops an economic framework which explains the welfare loss to consumers from imperfect information and provides a mechanism for analyzing the benefits from improved information. The model is applied to imperfect net weight information for packaged chicken and empirical estimates of the resulting welfare loss are obtained.     

Shoppers' Reactions to Supermarket Price Scanning and Shopper Price Marking

Supermarkets are starting to adopt price scanning checkouts. Other supermarkets, both scanner equipped and non-scanner equipped, are removing individual item prices. Although much has been written, especially in the retail trade press, about the advantages to retailers of scanner check-outs little attention has been paid to shopper reactions. This study sought to determine the attitudes and behavior of shoppers at scanner equiped supermarkets. Some user reactions to self-price marking of purchases was also determined.     

Growth and Welfare Maximization in Models of Public Finance and Endogenous Growth

This paper evaluates the trade‐off between growth and welfare maximization from two perspectives. First, it synthesizes and extends endogenous growth models with public finance to compare the growth‐ and welfare‐maximizing tax rates. Second, it examines the distinct model outcomes in terms of the growth rates and welfare levels. This comparison highlights the range of trade‐offs: the growth‐maximizing tax rate can lie above, below, or on the welfare‐maximizing equivalent. We find however that even relatively large differences in growth‐ and welfare‐maximizing tax rates translate into relatively small differences in growth rates, and, in some cases, welfare levels.     

Neutral Property Taxation

A major difficulty in implementing land/site value taxation is imputing the land value of built‐on sites. The literature has focused on two alternatives. The first, residual site value, measures postdevelopment site value as property value less structure value, with structure value measured as depreciated construction costs. Residual site value would be relatively easy to estimate, but a residual site value tax system, which taxes land value before development and residual site value after development at the same rate is distortionary, discouraging density. The second, raw site value, measures postdevelopment site value as “what the land would be worth were there no building on the site (though in fact there is).” Raw site value taxation is neutral (does not distort the timing and density of development), but the estimation of postdevelopment raw site value would be complex so that assessment would likely be less fair and more arbitrary, contentious, and prone to abuse. This paper asks the question: Is it not possible to design a property tax system (taxation of predevelopment land value, postdevelopment structure value, and postdevelopment site value at possibly different rates) that employs the administratively simpler residual definition of postdevelopment site value and achieves neutrality? Under restrictive assumptions and subject to an important qualification, the paper provides an affirmative answer, and characterizes the tax rates that achieve neutrality. It also briefly discusses issues of practical implementation.     

DEMAND RESPONSE TO COST SHARING UNDER MANAGED HEALTH CARE

We use 1996 Medical Expenditure Panel Survey to examine the demand response of ambulatory medical services to demand-side cost sharing under managed health care and find that demand response to a coinsurance rate is less than that under conventional plans. To address the selection problem, only respondents who were offered a single insurance plan from private establishments are studied. Our results show that managed care, relying on different approaches to ration, has blunted demand response. This suggests that in a managed care context, increasing demand-side cost sharing will reduce costs to plans mainly by shifting costs to enrollees. ( JEL I11)
