The Effects of Sarbanes-Oxley on Reporting Profits
Journal of Accounting & Marketing
This paper looks at the effects of Sarbanes-Oxley on the practice known as Earnings Management. Using earnings as reported in quarterly corporate filings, I employ a test of discontinuity used by DeGeorge, Patel and Zeckhauser to estimate the discontinuity in reported earnings per share (EPS) following a major accounting reform resulting from Sarbanes-Oxley. I find that the previous discontinuities found in the literature in reported EPS at 0¢ and 1¢ disappear after the accounting reform. Using
... a standard market model on security prices, I also find that short-term abnormal returns to reporting 1¢ EPS decrease following this reform, which could indicate positive shortterm returns to Earnings Management.

The author is willing to share all data used for this analysis. 1 See, for example: Baber and Kang [15,16]; Beatty, Ke, and Petroni ; Beaver, McNichols, and Nelson ; Brown and Caylor ; Collins, Pincus, and Xie ; Easton ; Gunny, Jacob, and Jorgensen ; Holland and Ramsay ; Jacob and Jorgensen ; Kerstein and Rai ; Keung, Lin, and Shih; Melumad and Nissim ; Phillips et al. ; Rego and Frank ; and Revsine et al. . 2 PCAOB Auditing Standard No. 1 requires that auditors' reports on audits and other engagements relating to public companies and other issuers include a reference that the engagement was performed in accordance with the standards of the PCAOB. This replaced the previous reference to generally accepted auditing standards.
