Description
In this paper, I investigate whether participation in employee stock option exchange programs contains private information about future stock returns. High participation in employee stock option exchange programs is associated with negative future abnormal returns over the ensuing 12-month period. This association is moderated by the transparency of the firm's information environment: high institutional ownership and high financial statement informativeness weaken the negative relation between participation and abnormal returns. Controlling for transparency of the firms' information environment, the association between participation and future returns arises primarily from firms that allow the CEO to participate.

Description
Responding to the allegedly biased research reports issued by large investment banks, the Global Research Analyst Settlement and related regulations went to great lengths to weaken the conflicts of interest faced by investment bank analysts. In this paper, I investigate the effects of these changes on small and large investor confidence and on trading profitability. Specifically, I examine abnormal trading volumes generated by small and large investors in response to security analyst recommendations and the resulting abnormal market returns generated. I find an overall increase in investor confidence in the post-regulation period relative to the pre-regulation period consistent with a reduction in existing conflicts of interest. The change in confidence observed is particularly striking for small traders. I also find that small trader profitability has increased in the post-regulation period relative to the pre-regulation period whereas that for large traders has decreased. These results are consistent with the Securities and Exchange Commission's primary mission to protect small investors and maintain the integrity of the securities markets.

Description
This study investigates the relation between the line of service (audit, tax, advisory) of Big Four office managing partners (OMPs) and both non-audit service fees and audit quality. Given that audit quality has been shown to vary across offices and because changes in office-level leadership can impact the office culture, I examine the impact of the OMP’s line of service on non-audit service fees and audit quality. I find that when an accounting firm office changes leadership to an advisory OMP, non-audit service revenues increase while audit quality suffers. This finding is consistent with advisory partners encouraging an office culture that emphasizes selling non-audit services more than conducting quality audits. Overall, this study provides evidence consistent with regulators’ concerns that the recent trend toward greater advisory services at the largest accounting firms reduces their focus on providing high-quality audits, thereby leading to decreased audit quality.
