The purpose of this paper is to re-examine the recent findings in Gaver and Utke (2019) (GU) who find that seasoned industry specialist auditors provide higher audit quality. We first illustrate how the magnitude of residuals from the accruals model can vary significantly by industry, thus highlighting the importance of including industry fixed effects when the dependent variable is discretionary accruals. We next replicate GU’s findings. We first attempt to replicate prior literature after including industry fixed effects in the audit quality (discretionary accruals) models. This is an important control, as the relevant benchmark for a firm with an industry specialist auditor is a peer firm in the same industry with a non-specialist auditor. We find that after including industry fixed effects, there is no association between seasoned industry specialist auditors and discretionary accruals. We also find that the association between industry specialization and discretionary accruals is very sensitive to the way in which the researcher calculates specialization. Our findings are informative for shareholders of public companies who vote on auditor ratification.

本文的目的是重新检验Gaver和Utke（2019）（GU）的最新发现，他们发现经验丰富的行业专业审计师可以提供更高的审计质量。我们首先说明应计模型中残差的大小如何随行业而显着变化，从而突出说明了当因变量为自由应计时，包括行业固定效应的重要性。接下来，我们将复制GU的发现。在将行业固定影响纳入审计质量（酌情应计制）模型之后，我们首先尝试复制以前的文献。这是一项重要的控制措施，因为具有行业专家审核员的公司的相关基准是同一行业中具有非专家审核员的同行公司。我们发现，在包括行业固定效应之后，经验丰富的行业专家审核员与应计应计项目之间没有关联。我们还发现，行业专业化与可自由支配权之间的关联对研究人员计算专业化的方式非常敏感。我们的发现对那些对批准审计师投票的公众公司股东具有参考价值。
