This paper documents the empirical distributions of daily trading volume prediction errors for several commonly used volume measures and expectation models for individual firms and for portfolios. The prediction errors for raw volume measures are significantly positively skewed, with thin left tails and fat right tails. However, natural log transformations of the volume measures are approximately normally distributed. For longer than one-day prediction intervals, recognition of autocorrelation in daily trading volume is advantageous for detecting abnormal trading. Results of analysis for clustering of events and for different size firms are also presented.

An analysis of the dual problem described by Ronn (1987) reveals that it provides a powerful and easily interpretable test for the hypothesis of a single class of marginal investors, including models of equilibrium based on a “representative tax bracket.” When Ronn's empirical tests are interpreted via the dual, they lend additional support to his conclusions in providing a strong rejection of the representative tax bracket hypothesis. A valid dual LP used to test the hypothesis can be obtained with fewer assumptions than Ronn's primal; in addition, a minor error in Ronn's presentation of the dual is corrected.

Abstract. A newly issued AICPA auditing standard focuses attention on analytical procedures. Regression analysis has been shown to be a useful audit tool and is used to a limited extent in practice. This study compares a univariate regression‐based decision rule with that of exponential smoothing. The effect on the regression‐based decision method when additional input information is included to develop a multivariate model is also evaluated. Comparisons are accomplished by seeding various error patterns into the audit period data and evaluating the results of the various models. The results indicate that the regression‐based decision model was at least as efficient and effective as the exponential smoothing‐based model. Additional input information into the univariate regression model to develop a multivariate model did improve auditor decisions for some types of accounts but did not significantly affect the number of incorrect rejections and/or acceptances for other types. The multivariate model did improve the achieved precision of the univariate model but still did not reach desired levels. Résumé. Dans un Auditing Standards Procedures qu'il publiait récemment, l'AICPA se penche sur les procédés analytiques. L'analyse de régression s'est révélée un instrument de vérification utile et son emploi dans la pratique est modéré, Les auteurs comparent une règle de décision fondée sur une régression comportant une seule variable aléatoire avec celle du lissage exponentiel. L'incidence d'un supplément d'information à l'entrée sur la méthode de décision fondée sur la régression permet de mettre au point un modèle à plusieurs variables aléatoires, que les auteurs évaluent également. Les comparaisons sont réalisées en introduisant divers scénarios d'erreur dans les données de la période soumise à la vérification. Les résultats de l'étude indiquent que le modèle de décision fondé sur la régression est au moins aussi efficient et efficace que le modèle fondé sur le lissage exponentiel. L'introduction d'un supplément d'information dans le modèle de régression à une seule variable aléatoire de manière à créer un modèle à plusieurs variables aléatoires a de fait amélioré les décisions du vérificateur pour certains types de comptes, mais n'a pas eu d'incidence significative sur le nombre d'erreurs de première et de seconde espèces pour d'autres types de comptes. La performance du modèle à plusieurs variables aléatoires est de fait supérieure à celle du modèle à une seule variable aléatoire, sans toutefois permettre d'obtenir les niveaux de précision souhaités.

This study investigates senior management turnover in financially distressed firms. In any given year, 52% of sampled firms experience turnover if they are either in default on their debt, bankrupt, or privately restructuring their debt to avoid bankruptcy. A significant number of changes are initiated by firms' bank lenders. Following their resignation from these firms, managers are not subsequently employed by another exchange-listed firm for at least three years. Results are consistent with managers experiencing large personal costs when their firms default.

This paper develops a model of inefficient managerial behavior in the face of a rational stock market In an effort to mislead the market about their firms' worth, managers forsake good investments so as to boost current earnings. In equilibrium the market is efficient and is not fooled: it correctly conjectures that there will be earnings inflation, and adjusts for this in making inferences. Nonetheless, managers, who take the market's conjectures as fixed, continue to behave myopically. The model is useful in assessing evidence that has been presented in che “myopia” debate. It also yields some novel implications regarding firm structure and the limits of intergation.

Using data on stock price and dividends, and on long-term and short-term interest rates, the authors test an important implication of present value models--that current value is a linear function of the conditional expectations of the next-period value and the current determining variable . This implication, combined with rational expectations, is strongly rejected. Combined with adaptive expectations, it is accepted. The latter model can also explain the observed negative relation between the rate of return and stock price. Thus the rational expectations assumption should be used with caution; the adaptive expectations assumption may be useful in econometric practice.

This article documents an apparent pricing anomaly involving 94 percent, 30-year Treasury bonds during the months of May and June 1986. During this period, the price of the 94s rose sharply relative to the prices of other long-term Treasury bonds and created a potential arbitrage opportunity. In addition, owners of the 94 bonds were able to borrow at a zero interest rate bypledging their bonds. Detailed examination reveals that this relative pricing anomaly cannot be attributed to changes in the level or term structure of interest rates or to differences between the bonds with respect to liquidity, taxation, or duration.
