[This paper examines the relations between the disclosure practices of firms, the number of analysts following each firm and properties of the analysts' earnings forecasts. Using data from the Report of the Financial Analysts Federation Corporate Information Committee (FAF Report 1985-89), we provide evidence that firms with more informative disclosure policies have a larger analyst following, more accurate analyst earnings forecasts, less dispersion among individual analyst forecasts and less volatility in forecast revisions. The results enhance our understanding of the role of analysts in capital markets. Further, they suggest that potential benefits to disclosure include increased investor following, reduced estimation risk and reduced information asymmetry, each of which have been shown to reduce a firm's cost of capital in theoretical research.]

In this paper we examine the relation between a firm's stock return and the earnings of other firms in the same industry, controlling for the firm's own earnings. We present a model in which the sign of this relation depends on the relative uncertainty there is about the size of the total industry value versus the division of that value between firms. We document considerable cross‐industry variation in the relation between a firm's return and other firms' earnings, and demonstrate empirically that the sign of the relation depends on information provided prior to the industry earnings announcement period. Résumé. Les auteurs examinent la relation entre le rendement de l'action d'une société et les bénéfices des entreprises appartenant au même secteur d'activité, en veillant à contrôler les bénéfices de la société en question. Dans le modèle qu'ils proposent, le sens (positif ou négatif) de cette relation dépend de l'incertitude relative qui caractérise l'importance de la valeur globale du secteur d'activité par rapport au partage de cette valeur entre les entreprises qui le constituent. Les auteurs ont recueilli quantité d'information confirmant l'existence d'une forte variation dans la relation entre le rendement des actions d'une entreprise et les bénéfices des autres entreprises d'un même secteur; ils démontrent aussi empiriquement que le sens de la relation dépend de l'information produite avant la période où les bénéfices du secteur sont communiqués.
