Previous work shows that average returns on common stocks are related to firm characteristics like size, earnings/price, cash flow/price, book-to-market equity, past sales growth, long-term past return, and short-term past return. Because these patterns in average returns apparently are not explained by the CAPM, they are called anomalies. We find that, except for the continuation of short-term returns, the anomalies largely disappear in a three-factor model. Our results are consistent with rational ICAPM or APT asset pricing, but we also consider irrational pricing and data problems as possible explanations. RESEARCHERS HAVE IDENTIFIED MANY patterns in average stock returns. For example, DeBondt and Thaler (1985) find a reversal in long-term returns; stocks with low long-term past returns tend to have higher future returns. In contrast, Jegadeesh and Titman (1993) find that short-term returns tend to continue; stocks with higher returns in the previous twelve months tend to have higher future returns. Others show that a firm's average stock return is related to its size (ME, stock price times number of shares), book-to-marketequity (BE/ME, the ratio of the book value of common equity to its market value), earnings/price (E/P), cash flow/price (C/P), and past sales growth. (Banz (1981), Basu (1983), Rosenberg, Reid, and Lanstein (1985), and Lakonishok, Shleifer and Vishny (1994).) Because these patterns in average stock returns are not explained by the capital asset pricing model (CAPM) of Sharpe (1964) and Lintner (1965), they are typically called anomalies. This paper argues that many of the CAPM average-return anomalies are related, and they are captured by the three-factor model in Fama and French (FF 1993). The model says that the expected return on a portfolio in excess of the risk-free rate [E(Ri) - Rf] is explained by the sensitivity of its return to three factors: (i) the excess return on a broad market portfolio (RM - Rf); (ii) the difference between the return on a portfolio of small stocks and the return on a portfolio of large stocks (SMB, small minus big); and (iii) the difference between the return on a portfolio of high-book-to-market stocks and the return on a portfolio of low-book-to-market stocks (HML, high minus low). Specifically, the expected excess return on portfolio i is,

Multifactor Explanations of Asset Pricing Anomalies

This paper evaluates alternative models for detecting earnings management. The paper restricts itself to models that assume the construct being managed is discretionary accruals, since such models are commonly used in the extant accounting literature. Existing models range from simple models in which discretionary accruals are measured as total accruals, to more sophisticated models that separate total accruals into a discretionary and a non-discretionary component. Prior to this paper, there had been no systematic evidence bearing on the relative performance of these alternative models at detecting earnings management. This paper evaluates the relative performance of the competing models by comparing the specification and power of commonly used test statistics across the measures of discretionary accruals generated by each model. The specification of the test statistics is evaluated by examining the frequency with which they generate type I errors for a random sample of firm-years and for samples of firm-years with extreme financial performance. We focus on samples with extreme financial performance because the stimuli investigated in previous research are frequently correlated with financial performance. The first sample of firms are targeted by the Securities and Exchange Commission for allegedly overstating annual earnings and the second sample is created by artificially introducing earnings management into a random sample of firms.

Industry costs of equity

Corporate disclosure is critical for the functioning of an efficient capital market. Firms provide disclosure through regulated financial reports, including the financial statements, footnotes, management discussion and analysis, and other regulatory filings. In addition, some firms engage in voluntary communication, such as management forecasts, analysts? presentations and conference calls, press releases, internet sites, and other corporate reports. Finally, there are disclosures about firms by information intermediaries, such as financial analysts, industry experts, and the financial press.

Regression Diagnostics: Identifying Influential Data and Sources of Collinearity

This paper evaluates alternative accrual-based models for detecting earnings management. The evaluation compares the specification and power of commonly used test statistics across the measures of discretionary accruals generated by the models and provides the following major insights. First, all of the models appear well specified when applied to a random sample of firm-years. Second, the models all generate tests of low power for earnings management of economically plausible magnitudes (e.g., one to five percent of total assets). Third, all models reject the null hypothesis of no earnings management at rates exceeding the specified test-levels when applied to samples of firms with extreme financial performance. This result highlights the importance of controlling for financial performance when investigating earnings management stimuli that are correlated with financial performance. Finally, a modified version of the model developed by Jones (1991) exhibits the most power in detecting earnings management.

Detecting earnings management

. This study investigates firms subject to accounting enforcement actions by the Securities and Exchange Commission for alleged violations of Generally Accepted Accounting Principles. We investigate: (i) the extent to which the alleged earnings manipulations can be explained by extant earnings management hypotheses; (ii) the relation between earnings manipulations and weaknesses in firms' internal governance structures; and (iii) the capital market consequences experienced by firms when the alleged earnings manipulations are made public. We find that an important motivation for earnings manipulation is the desire to attract external financing at low cost. We show that this motivation remains significant after controlling for contracting motives proposed in the academic literature. We also find that firms manipulating earnings are: (i) more likely to have boards of directors dominated by management; (ii) more likely to have a Chief Executive Officer who simultaneously serves as Chairman of the Board; (iii) more likely to have a Chief Executive Officer who is also the firm's founder, (iv) less likely to have an audit committee; and (v) less likely to have an outside blockholder. Finally, we document that firms manipulating earnings experience significant increases in their costs of capital when the manipulations are made public.

Resume. Les auteurs analysent les entreprises assujetties aux mesures d'execution prises par la Securities and Exchange Commission dans les cas de presomption de transgression des principes comptables generalement reconnus. Ils s'interessent aux aspects suivants de la question: i) la mesure dans laquelle les presomptions de manipulations des benefices peuvent etre expliquees par les hypotheses existantes de gestion des benefices; ii) la relation entre les manipulations de benefices et les faiblesses des structures de regie interne des entreprises; et iii) la reaction du marche financier a l'endroit des entreprises au sujet desquelles les presomptions de manipulation des benefices sont rendues publiques. Les auteurs constatent qu'un incitatif majeur a la manipulation des benefices est le desir d'obtenir du financement externe a moindre cout. Ils demontrent que cet incitatif demeure important meme apres le controle des motifs contractuels que mettent de l'avant les travaux theoriques. Ils constatent egalement que les entreprises qui manipulent les benefices sont: i) davantage susceptibles d'avoir des conseils d'administration domines par la direction; ii) davantage susceptibles d'avoir un chef de la direction qui joue simultanement le role de president du conseil; iii) davantage susceptibles d'avoir un chef de la direction qui est egalement le fondateur de l'entreprise; iv) moins susceptibles d'avoir un comite de verification; et v) moins susceptibles d'avoir un bloc de titres detenus par un actionnaire exterieur. Enfin, les auteurs etablissent le fait que le cout du capital, pour les entreprises qui manipulent les benefices, enregistre des hausses appreciables lorsque ces manipulations sont rendues publiques.

Causes and Consequences of Earnings Manipulation: An Analysis of Firms Subject to Enforcement Actions by the SEC*

This paper investigates whether stock prices reflect information about future earnings contained in the accrual and cash flow components of current earnings. The extent to which current earnings performance persists into the future is shown to depend on the relative magnitudes of the cash and accrual components of current earnings. However, stock prices are found to act as if investors "fixate" on earnings, failing to reflect fully information contained in the accrual and cash flow components of current earnings until that information impacts future earnings.
