This paper presents a partially revealing rational expectations model of competitive trading to identify two effects of information releases; an informedness effect and a consensus effect. The informedness effect measures the extent to which agents become more knowledgeable, and the consensus effect measures the extent of agreement among agents at the time of an information release. We demonstrate that informedness and consensus generally occur jointly when information is disseminated, and that unexpected price changes and trading volume are each influenced by both informedness and consensus. Thus, interpretations of unexpected price changes and volume associated with information releases are conceptually similar. Since informedness and consensus each affect both the variance of price changes and volume, our paper provides an economic rationale for examining both price and volume effects at the time of information releases.

This paper documents the effects of large (block) transactions on the prices of common stocks traded on the New York Stock Exchange. We examine whether mean temporary and permanent price effects associated with large and small transactions differ and whether the price effects vary cross-sectionally according to the size of the block. Alternative definitions of block size are investigated – percentage of the equity traded, block volume in relation to normal trading volume, and dollar value of the block. The results suggest that price effects are predominantly temporary for seller-initiated transactions and permanent for buyer-initiated transactions.

We examine the profitability of a trading strategy which is based on a logit model designed to predict the sign of subsequent twelve-month excess returns from accounting ratios. Over the 1978–1988 period, the average annual excess return produced by the trading strategy ranges between 4.3% and 9.5%, depending on the specific measure of excess return and weighting scheme involved. However, our implementation of the Ou and Penman (1989) trading strategy in the 1978–1988 period, which is based on a logit model that predicts subsequent unexpected earnings- per-share from accounting ratios, does not earn excess returns.

[This paper investigates the extent to which models based on financial and market variables predict auditors' decisions to issue qualified audit reports in situations involving contingencies or uncertainties. A probit model is developed with the dependent variable indicating whether the firm received a qualified opinion, and the independent variables representing publicly available financial and market variables. The estimated model distinguishes between unqualified (clean) opinions and first-time qualifications and between types of qualifications (e.g., going concern, litigation, asset realizing, and multiple qualifications) in the year of the qualification, for both an estimation sample and a holdout sample. The predictive accuracy of the estimated model is evaluated in terms of misclassification costs for alternative costs of type I and type II errors and for specific prior probabilities of qualified and clean opinions.]

We examine the accounting and market performance of reverse leveraged buyouts (i.e., firms making their first public offering after previously completing a leveraged buyout). On average, the accounting performance of these firms is significantly better than their industries at the time of the initial public offering (IPO) and for at least the following four years, though there is some evidence of a decline in performance. Cross-sectional variation in accounting performance subsequent to the IPO is related to changes in the equity ownership of both operating management and other insiders, and is unrelated to changes in leverage. Finally, there is no evidence of abnormal common stock performance after the reverse leveraged buyout.

This paper examines daily excess bond returns associated with announcements of additions to Standard and Poor's Credit Watch List, and to rating changes by Moody's and Standard and Poor's. Reliably nonzero average excess bond returns are observed for additions to Standard and Poor's Credit Watch List when an expectations model is used to classify additions as either expected or unexpected. Bond price effects are also observed for actual downgrade and upgrade announcements by rating agencies. Excluding announcements with concurrent disclosures weakens the results for downgrades, but not upgrades. The stock price effects of rating agency announcements are also examined and contrasted with the bond price effects.

We find that measures of board and ownership structure explain a significant amount of cross-sectional variation in CEO compensation, after controlling for standard economic determinants of pay. Moreover, the signs of the coefficients on the board and ownership structure variables suggest that CEOs earn greater compensation when governance structures are less effective. We also find that the predicted component of compensation arising from these characteristics of board and ownership structure has a statistically significant negative relation with subsequent firm operating and stock return performance. Overall, our results suggest that firms with weaker governance structures have greater agency problems; that CEOs at firms with greater agency problems receive greater compensation; and that firms with greater agency problems perform worse.
