The association between auditor quality and human capital

Abstract

Purpose

Following the high profile collapses of Enron and WorldCom, and the demise of Andersen, human capital (HC) has become a key driver of auditor quality. The purpose of this study is to investigate if there is a positive association between HC and auditor quality in public accounting firms and if the extent of association varies between accounting firms.

Design/methodology/approach

Multiple regression and logistic modeling are applied to examine the association between auditor quality and HC. The sample consists of 4,865 firm‐year observations over the period from 1989 to 2004.

Findings

The main findings indicate that higher investments in HC correspond to a higher level of auditor quality. Furthermore, the power of HC on auditor quality has a significant difference between public and non‐public audit market firms.

Research limitations/implications

A number of theoretical and measurement limitations are acknowledged that could further increase the statistical power of the tests.

Practical implications

The findings should be of interest to regulators, auditors, audit clients, and academics. The findings also suggest that HC has an impact on overall auditor quality. The audit firms need more well‐educated and well‐trained professionals with the experience to keep pace with the changing nature of the market and to perform audit tasks.

Originality/value

The findings fill a gap in the literature regarding auditor quality and HC from the perspective of public accounting firms.
