Regulators around the world are concerned about the potentially harmful effects of high audit market concentration on audit pricing and quality. However, results in the overall literature have failed to reach consensus on this issue. We contribute to this debate by arguing that the audit market...

Following large-scale auditor consolidations in the late 1980s and early 1990s, along with Arthur Andersen's collapse in 2001, the global audit market has become highly concentrated during the past 30 years. Many interested parties, including regulators, researchers, and practitioners, disagree...

We investigate how a high degree of audit market concentration and auditor reputation affect audit quality. Using audit adjustments to student loan loss provisions in government audits to construct a new measure for excessive audit conservatism, we show that an audit market monopoly leads to...

What are the implications of major customer dependency, i.e., the degree of a supplier firm's dependency on its major customers, for external auditors? While the conventional view emphasizes the negatives of major customer dependency for client business risk, we find that suppliers with more...

This paper focuses on audit market concentration of listed firms which is characterized by an oligopoly of “Big Four” audit firms. Hence a state of the art analysis of the status quo of concentration measurement has been conducted on the audit market from an international perspective....

Examining a drastic evolution of the audit market in China, we find that auditor mergers enhance clients' innovation. This effect is more pronounced when the acquirer in a merger is an international Big 4 auditor or when a merger leads to a greater increase in auditor size, supporting the...

This study divides the audit market into the oligopolistic and atomistic segments at MSA level and examine whether the effect of audit market concentration on audit fees and audit quality is the same in these two segments. I find that the market concentration raises the audit fees in the...

Prior research provides mixed evidence about whether sufficient audit market competition exists and whether competition impairs or improves audit quality. A major impediment to this stream of research is the unobservable nature of the bidding process by which auditors compete for clients. In...

We use a long time-series from Australia to investigate the determinants and (to a lesser extent) consequences of audit market concentration. We show that increasing skewness in the size of public companies is associated with increased audit market concentration, and that the growth of the large...

The switch to IFRS in Europe opens the opportunities to investigate the relationship between a drastic change in the complexity of financial reporting standards and the audit market dynamics. Following concerns that mandated IFRS may have increased the domination of the global audit firms, we...
