This paper provides a rational explanation for the apparent ability of managers to successfully time the maturity of their debt issues. We show that a structural break in excess bond returns during the early 1980s generates a spurious correlation between the fraction of long‐term debt in total debt issues and future excess bond returns. Contrary to Baker, Taliaferro, and Wurgler (2006) , we show that the presence of structural breaks can lead to nonsense regressions, whether or not there is any small sample bias. Tests using firm‐level data further confirm that managers are unable to time the debt market successfully.

This paper investigates the market's reaction to U.K. insider transactions and analyzes whether the reaction depends on the firm's ownership. We present three major findings. First, differences in regulation between the U.K. and United States, in particular the speedier reporting of trades in the U.K., may explain the observed larger abnormal returns in the U.K. Second, ownership by directors and outside shareholders has an impact on the abnormal returns. Third, it is important to adjust for news released before directors' trades. In particular, trades preceded by news on mergers and acquisitions and CEO replacements contain significantly less information.
