DO BRAND NAMED AUDITORS MITIGATE CASH FLOW MANAGEMENT POST-SOX?

This paper examines the relation between named auditors and cash flow management. However, I didn't find a significant effect of audit firm on cash flow management. It means that brand named auditors, both Big 4 and the second tier public audit firms do not help mitigate cash flow management post-SOX. This is not surprising as auditors alone cannot curb managerial opportunism because other participants such as regulators (i.e., SEC and FASB) have not exerted a concerted effort to provide transparent accounting rules for the SCF model.
