PCAOB International Inspections and Audit Quality
研究了PCAOB首次检查外国会计师事务所对其美国跨境客户的影响，发现检查后应计异常降低、会计数字价值相关性提高，且联合检查与单独检查效果不同。
ABSTRACT We investigate the impact of the Public Company Accounting Oversight Board's (PCAOB) first-time inspections of foreign accounting firms by examining abnormal accruals around the inspection year, and the value relevance of accounting numbers around the inspection report date, for their U.S. cross-listed clients. We document lower abnormal accruals in the post-inspection period, and greater value relevance of accounting numbers in the post-report period for clients of the inspected auditors, compared with non-cross-listed clients or clients of non-inspected auditors within the inspected countries. Comparisons of the PCAOB's joint inspections with PCAOB stand-alone inspections indicate that while both experience lower post-inspection abnormal accruals, the former benefit more than the latter. The value relevance measure, in contrast, shows greater increases for the PCAOB stand-alone inspections than for joint inspections. Comparing the inspection effects for auditors with and without deficiency reports, we find no systematic differences for accruals or for value relevance.
