In this paper, we investigate the property of analysts’ consensus and the impact of public information in the situation where the strategic interaction between analysts exists. As a result, we obtain the following results. First, the accuracy of consensus forecast is positively related with accuracies of individual analysts’ forecasts, and with forecasts dispersion. Second, as analysts’ strategic motives become stronger, the accuracy of consensus declines. Third, public information improves accuracies of individual analysts’ forecasts mostly, but whether the consensus becomes more accurate or not is not determined definitely. Finally, the relation of accuracy of public information and consensus depends on several parameters such as the accuracy ratio of public information to private information, and the strength of strategic motives. The result shows that dispersion of forecasts will enhance the accuracy of consensus, and strategic interaction or public information reduces the dispersion of forecasts.
