Abstract. This paper examines stock market behavior associated with interim earnings and marketing‐production disclosures by NYSE industrial corporations during 1905–10. Mean stock price changes are examined to assess whether these firms were more likely to disclose favorable information. We also examine the magnitude of price changes and trading volume to provide evidence on the credibility of these disclosures as perceived by investors. The sample and time period we examine enable us to evaluate the stock market effects of interim disclosures in a discretionary disclosure environment. We find no evidence that these firms were more likely to selectively disclose favorable interim information based on contemporaneous stock price changes. Also, no significant differences are detected in the incidence of interim disclosure before dividend or annual earnings increases compared to dividend cuts/omissions or annual earnings declines. We also document increased trading volume in the announcement week and prior weeks, but significant price changes are restricted to the preannouncement period. These results are driven by firms that do not frequently disclose interim information, and these firms' disclosures are frequently accompanied by concurrent news items (in particular, new financings). Price and volume results are weakly sensitive to the exclusion of cases with concurrent news items. Collectively, our results suggest no systematic tendency to disclose favorable information and managerial disclosures were at least partially credible in the early 20th century disclosure environment. Résumé. Les auteurs examinent la réaction du marché des valeurs mobilières à la publication d'information périodique relative aux bénéfices ainsi qu'à la production et au marketing, par les sociétés industrielles dont les titres étaient inscrits à la Bourse de New York durant la période 1905–1910 et s'intéressent aux variations du cours moyen des titres, afin d'évaluer si ces sociétés étaient davantage enclines à publier de l'information favorable. Ils examinent également l'ampleur des variations du cours des titres et du volume des opérations afin d'établir comment les investisseurs percevaient la crédibilité de l'information publiée. Les variations du cours des titres observées à l'époque ne permettent pas de conclure que ces sociétés étaient davantage enclines à sélectionner l'information périodique la plus favorable, et les auteurs ne détectent pas non plus de différences significatives dans les conséquences de la publication d'information périodique préalablement à des hausses de dividendes ou de bénéfices annuels, par rapport à des réductions ou des omissions de dividendes ou des diminutions des bénéfices annuels. Dans l'ensemble, les résultats portent à croire qu'il n'y a pas de tendance systématique à la publication d'information favorable, et que l'information publiée par la direction est au moins en partie crédible dans le contexte du début du XX e siècle.

Abstract This paper investigates the relation between industry‐wide information disclosures by the trade association for the semiconductor industry and both share prices and analyst forecasts. Such disclosures may have little impact on investors and analysts, since prior theoretical research suggests that trade associations may be unable to secure reliable data from firms in an industry. At the same time, such disclosures may be important, since prior empirical research suggests that share prices and analyst forecasts reflect industry‐wide earnings effects earlier than firm‐specific effects. We document significant stock price movements on release dates of industry Flash Reports by the Semiconductor Industry Association (SIA) each month that contain aggregate industry data on new orders and shipments. The magnitude of the price revisions on Flash Report disclosure dates is positively associated with changes in the numbers disclosed and varies across sample firms in a manner associated with identifiable characteristics of the firms. Further tests indicate that the Flash Report provides mainly forward‐looking information on new orders that is linked to firm‐specific sales changes and has explanatory power for quarterly stock prices beyond firm‐specific earnings. This information is used by security analysts mainly in assessing the persistence of firm‐specific quarterly sales changes. Our findings support the hypothesis that the SIA is able to obtain data from firms, compile it into reliable aggregate statistics, and then distribute these statistics in a timely fashion.

Abstract. This paper examines the properties of corporate disclosure and price discovery associated with NYSE temporary trading halts. We address the hypothesis that managers release highly informative disclosures outside of trading hours or seek a trading halt to allow investors greater opportunity to assess the implications of new information. We investigate whether: (a) disclosures associated with trading halts are highly price informative, and (b) the process of price discovery as reflected in specialist indications is more protracted and difficult for extreme and bad news halts. We find that halts arise from non‐routine highly informative disclosures for which price discovery is more uncertain and protracted. First, most disclosures associated with our sample of trading halts are ones whose arrival investors cannot predict but which have large valuation effects (e.g., corporate takeovers and leveraged buyouts). Second, halts associated with large price changes exhibit more uncertain and protracted price discovery during the halt. Specialist indications for extreme news halts have (1) bigger differences between high and low prices, (2) poorer predictive accuracy with respect to opening price, and (3) greater frequency. Finally, similar comparisons for bad and good news only weakly support the conjecture that bad news is associated with more certain and protracted price discovery. Résumé. Les auteurs examinent les propriétés des renseignements fournis par les sociétés et de la supputation des cours en période d'arrêt temporaire des opérations de la Bourse de New York. Ils se penchent sur l'hypothèse selon laquelle les gestionnaires publient des renseignements très informatifs en dehors des heures d'activite ou en période d'arrêt des opérations, de façon à donner aux investisseurs tout le loisir d'évaluer les conséquences de ces renseignements. Les auteurs se demandent 1) si l'information publiée en période d'arrêt des opérations est très éclairante sur les cours et b) si le processus de supputation du cours tel que l'illustrent les indications des spécialistes est plus long et plus difficile lorsque les arrêts sont associés à des renseignements qui entraînent des variations du cours d'une grande amplitude ou des variations du cours négatives. Selon les auteurs, il y a arrêt des opérations lorsque les renseignements publiés sortent de l'ordinaire et que leur contenu en information est élevé, si bien que le processus de supputation du cours est plus incertain et plus long. Premièrement, la plupart des déclarations associées à notre échantillon d'arrêts des opérations sont de nature telle qu'il était impossible pour les investisseurs d'en prédire l'occurrence, mais ont des conséquences majeures sur l'évaluation de l'entreprise (par exemple, les prises de contrôle et les prises de contrôle adossées). Deuxièmement, les arrêts des opérations correspondant à d'importantes variations du cours sont caractérisés par un processus de supputation du prix plus incertain et plus long. Les indications des spécialistes en ce qui a trait aux arrêts des opérations associés à des renseignements qui entraînent des variations du cours d'une grande amplitude présentent 1) un écart plus grand entre cours élevé et cours faible, 2) moins de précision dans les prédictions relatives au cours d'ouverture et 3) une fréquence supérieure. Enfin, des comparaisons analogues en ce qui a trait aux renseignements positifs et aux renseignements négatifs corroborent seulement faiblement l'hypothèse selon laquelle les renseignements négatifs rendent la processus de supputation du cours plus certain et plus long.

ABSTRACT A common view is that verified earnings reports encourage investment through improved transparency. We lack direct evidence on this foundational proposition because researchers cannot observe counterfactuals in which a manager either (i) must remain silent about performance or (ii) can make any statement about performance they desire, even a bald‐faced lie. We experimentally manipulate whether a manager can provide information to an investor by voluntarily disclosing a verified earnings report, communicating freely via unverifiable cheap talk, or both. Our experiment involves repeated interactions between an uninformed investor with funds that, if invested, generate uncertain gains, and a trustee‐manager who observes and then divides gains after they are realized. We hypothesize and find that (i) the provision of a verified earnings report leads to higher investment compared with a world in which reporting is not possible and (ii) the provision of a verified earnings report leads to more accurate cheap talk communication than when earnings reports are unavailable. Contrary to our prediction, we find that investment when both earnings reports and cheap talk are possible is statistically indistinguishable from investment when only cheap talk communication is available. Further tests reveal that a lack of verified earnings reports leads managers to sustain a partner's investment by providing high returns to the investor while also limiting (but not completely eliminating) deceptive communication and profit‐taking. Our main conclusion is that verified earnings reports promote investment on a stand‐alone basis by improving transparency, but the effect of greater transparency from earnings reports on investment is more nuanced when earnings reports can influence the disclosure of unverifiable information. The main implication of our evidence is that the greater transparency of management behavior with verified earnings reports is not unambiguously positive because making behavior more transparent can lead managers to change their behavior.
