Auditor knowledge is a key element in explaining the supply of audit quality, yet understanding of the drivers of this knowledge in the archival literature is limited. This study uses an archival approach to examine whether the sharing of auditors among firms in banking relationships results in information transfers that improve audit quality. I find that audit quality improves for both borrowers and lenders who share the same auditor office. Specifically, lenders who share an auditor office with their borrowers have more accurate loan-loss provisions, especially lenders with smaller commercial loan portfolios. Borrowers who share an auditor office with their lender are less likely to receive a clean audit opinion just prior to bankruptcy. Overall, these findings are consistent with shared auditors in banking relationships developing client specific knowledge that is transferable across clients and industries.

共享审计师能提高审计质量吗？来自银行关系的证据

审计师知识是解释审计质量供应的关键因素，但在档案文献中对这种知识驱动因素的理解有限。本研究使用档案方法来检验在银行关系中的公司之间共享审计师是否会导致提高审计质量的信息传输。我发现共享同一审计办公室的借款人和贷款人的审计质量都有所提高。具体而言，与借款人共用审计办公室的贷方有更准确的贷款损失准备金，尤其是商业贷款组合较小的贷方。与贷方共用审计办公室的借款人在破产前不太可能收到干净的审计意见。全面的，
