Abstract. Using a sample of 856 management earnings forecasts, we provide evidence that managers release larger shock-earnings forecasts in nontrading periods. Our results do not depend on whether the magnitude of the shock is measured exogenously (unexpected accounting earnings) or endogenously (security market reaction). The timing effects are more pronounced for less-precise (i.e., open-interval and closed-interval) forecasts. Also, we provide evidence of an overnight reaction to closed-period management forecast releases. Our results are consistent with explanations for voluntary disclosure that rely on a precommitted policy of information asymmetry reduction (see Diamond 1985; King, Pownall, and Waymire 1990). These explanations lead to predictions of strategic timing of greater shocks in the nontrading period in order to provide the less-informed with a period for information evaluation. Résumé. À partir d'un échantillon de 856 prévisions de bénéfices publiées par la direction de diverses entreprises, les auteurs démontrent que les prévisions publiées par les gestionnaires en période où les titres ne sont pas négociés ont davantage d'impact. Les résultats qu'ils obtiennent ne dépendent pas du caractère exogène (bénéfices comptables inattendus) ou endogène (réaction du marché des valeurs mobilières) de la mesure de l'impact. L'effet du choix du moment est plus prononcé pour les prévisions moins précises (c'est-à-dire à intervalle ouvert et à intervalle fermé). Les auteurs démontrent aussi qu'il se produit une réaction à la publication de prévisions par la direction en période de fermeture, dans les vingt-quatre heures qui suivent la publication. Les résultats de l'étude sont conformes au principe de la présentation facultative d'information dont l'explication repose sur une politique, préalablement adoptée, de réduction de l'asymétrie de l'information (voir Diamond, 1985; King, Pownall et Waymire, 1990). Cette explication mène à des prédictions voulant que l'on choisisse, à des fins stratégiques, les périodes de non-négociation des titres pour publier les prévisions de bénéfices dont l'impact est plus grand, de manière à laisser aux investisseurs moins bien informés un certain laps de temps pour évaluer l'information.  相似文献

This paper discusses the forces that have been at play in the debate over the recently concluded Canada-U.S. Free Trade Agreement. Most economists agree that free trade is desirable and that both parties likely will gain from specialization and exchange. But many objections to this agreement have been raised, some of which are very different from those that economists usually consider. A review of the agreement and many of the arguments raised against it reinforces the basic credo that freer exchange between consenting parties leads to improved economic well-being.  相似文献

Union representation elections are associated with significant declines in firm profitability. In addition to the significant mean effect of union elections on the equity value of firms, there exists substantial variation in the magnitude of equity losses across individual election events. Cross-sectional variation in shareholder equity losses can be explained by the labor intensity of the firm, the size of the union wage premium and fraction of workers organized in "the firm's industry,." the presence or absencse of right-to-work lows in the state where the election is held, the member of workers covered in the representaion election, and the number of previous union representation election in the firm. The empirical results indiacte the equity losses are the greatest in industries where union wage gain are the highest and unionization rates are the largest, and in the most labor-intensive firms, independent of the size of the bargaining unit involved in the election. The latter result indicates the presence of union spillover effects.  相似文献

Antitrust law distinguishes vertical and horizontal restraints. A horizontal restraint is one which exists between competing firms supplying rival products in a market, and a vertical restraint is one which exists between firms that jointly contribute to supplying a particular product in a market. Horizontal agreements receive much closer antitrust scrutiny because they often enable firms to limit competition at the expense of consumers, while vertical restraints may be legal or illegal depending on whether they tend to enhance or reduce competition or the exploitation of market power. This paper argues that there are important vertical restraints that operate in sports leagues which have been mostly neglected in the literature but have a significant impact. We focus on intraleague restraints, where member clubs of a league agree to control the organization of league competition, and interleague restraints, where horizontal agreement such as the Reserve Clause relies on agreements not to compete for players competing in senior or junior leagues.

Prospective earnings information in Australian firms' annual reports has been claimed to be of sufficient importance to warrant its statutory requirement, or at least its "active encouragement". With the introduction of AASB 1039 Concise Financial Reports, management discussion and analysis is required in some circumstances, although there is no explicit requirement to provide prospective earnings disclosures. A survey of a sample of ASX-listed firms shows that about 25% include some form of earnings forecast, although most are qualitative, while even a coarse measure of their accuracy suggests they are relatively unreliable. These results give rise to some concern that encouraging the provision of prospective earnings data may not necessarily assist investors.  相似文献
