This essay seeks to review the results of this research and provide a concise summary of the available evidence as of late 2007. Overall although SOX appears to have had some beneficial effects it has also: increased the costs of auditing governance and human capital and compliance more generally; induced a mis-match between auditors and firms; encouraged firms to delist or otherwise stay below the regulatory radar; lowered corporate investment and risk-taking; and had ambiguous effects on the quality of investor information and capital market eeffciency.pdfen-NZPermission to publish research outputs of the New Zealand Institute for the Study of Competition and Regulation has been granted to the Victoria University of Wellington Library.
