Although theory suggests that companies would rationally select into audit even if it were not a legal requirement, many countries impose mandatory audits. This is arguably due to an audit having elements of a public good, which may result in not enough audits being purchased without regulatory...

We argue that auditors are more conservative when they face high estimation risk. To test this, we examine how auditors respond to the estimation risk associated with predicting the future bankruptcy outcomes of their audit clients. Consistent with auditors being more conservative when they face...

After a long period of universal mandatory audit, the UK reduced the regulatory burden of private firms by introducing size-based audit exemption in 1994; the size thresholds have subsequently been progressively increased. Both accounting bodies and credit rating agencies have expressed reservations...

This study investigates whether financial reporting quality is affected by an auditor's experience of litigation in the recent past. We find that the likelihood of an accounting misstatement and the magnitudes of misstatements are significantly lower for non-Big 4 auditors who recently suffered...

We hypothesize that companies in the same product market avoid sharing the same audit partner when they are concerned about possible information spillovers. Consistent with our hypothesis, we find that product market rivals are less likely to share the same partner when they perceive that...

Executives are 'affiliated' if they previously worked for their companies' audit firms. I find most affiliations (71.3%) occur when auditors become employees of audit clients ('employment affiliations'), but affiliations also arise when companies hire executives' former CPA firms ('alma mater...

There are competing arguments and mixed prior evidence on whether firms that are aggressive in their financial reporting exhibit more or less tax aggressiveness. Our research contributes to resolving this issue by examining the association between aggressive tax reporting and the incidence of...

Many studies report that audit fees are discounted in the year of an auditor change and regulators have long been concerned that such fee discounting could impair audit quality. We find significant bias in the way studies have tested for fee discounting. The bias exists because interim...

We test whether PCAOB inspections help remediate auditors' deficiencies in detecting and reporting material internal control weaknesses. After PCAOB inspectors report higher rates of internal control audit deficiencies, we find that auditors respond by increasing their issuance of adverse...
