Abstract

Focusing on the merger of Price Waterhouse and Coopers & Lybrand in 1998, we document increased audit quality (measured by earnings quality of the clients) for the merged firm and other big-X auditors (The big-X auditors are Ernst & Young, Deloitte, KPMG and Arthur Anderson.) during the post-merger period because: (1) controlling for economic conditions, clients of big-X auditors have lower levels of absolute discretionary accruals and (2) the value relevance of earnings has significantly increased. Furthermore, we find evidence that in the post-merger period, there is a significant increase in audit fees for PricewaterhouseCoopers and other big-X client firms, which suggests that the effect of collectively enhanced market power of big-X auditors (which tends to increase audit fees) dominates the effect of cost savings from the merger (which tends to lower audit fees). The results have implications for regulators and policy makers.
