| Abstract: | In this paper I re-examine spreads around dividend and earnings announcements and provide new evidence on patterns by examining the components of the bid-ask spread. Transaction data are examined through a recently developed spread decomposition model that decomposes the bid-ask spread into a fixed (execution) component and an adverse selection component. In addition, this model does not rely on a constant spread as previous spread decomposition models require. The results show that around earnings announcements, the bid-ask spreads and spread components have significant changes indicating that the anticipated announcement is informative. However, the actual public announcement of a dividend does not alter the bid-ask spread and spread components of actively traded securities. |
