This study examines the impact of the Internet on earnings announcements, in an Australian context, with relation to (1) information content (2) post-earnings announcement drift (PEAD) and (3) information asymmetry. Our results for the pre-Internet (1996) and the post-Internet (2000) periods provide mixed evidence on the changes in the information content of earnings announcements. However, we detect a reduction in both the magnitude and duration of the post-earnings announcement drift in the post-Internet period for the positive unexpected earnings decile. The analysis on abnormal volume, spread and market depth do not show a significant change in information asymmetry between the pre- and post-Internet periods for preliminary final announcements.
