论文摘要：This study examines whether and how social ties between the CEOs and audit committees (AC) affect AC effectiveness over time. Based on a large dataset of U.S.-listed firms during 2004-2015, we document the following findings. First, we observe that CEO-AC social ties at the aggregate level have increased 5% during the sample period. At the individual level, employment ties have almost doubled from 10% in 2004 to 18% in 2015 while friendship ties and education ties remain relatively stable over time. Second, friendship ties adversely affect AC oversight quality (measured by discretionary accruals, audit fees, and likelihood of receiving going-concern opinion and internal control weakness report) in early post-SOX period (2004-2008). In recent years (2009-2015), the negative effect of friendship ties disappears and employment ties enhance AC oversight quality. These results are robust to controlling for endogeneity. The positive effect of employment ties on AC oversight quality is stronger when CEOs and ACs have prior working experience in the same industry, different gender, similar ages, and accounting expertise. Our empirical results bear important implications for regulators and investors.
