A Review of the Empirical Literature on Audit Market Concentration
Synopsis The research problem The extant audit market concentration (AMC) literature is quite scattered, which makes it challenging to comprehend the current state of knowledge and to highlight the areas that require further exploration. An improved understanding of AMC and its possible effects require a comprehensive review of the AMC literature, since no such review has yet been published. Therefore, our paper intends to: (a) synthesize the empirical work in the AMC literature; (b) determine the limitations in the ways AMC has been investigated; (c) identify avenues of inquiry that could guide future thinking on AMC; and (d) develop insights into how future AMC investigations can be further developed. Motivation The most noticeable developments in AMC occurred after the audit firm megamergers of the 1980s and 1990s and Andersen’s demise in 2002. This trend toward fewer and larger suppliers of auditing services has sparked intense debate about the costs and benefits of AMC. However, the literature provides mixed evidence on the determinants and consequences of AMC. Adopted methodology A structured literature review [Massaro, M., Dumay, J., & Guthrie, J. (2016).

期刊介绍:
The aim of The International Journal of Accounting is to advance the academic and professional understanding of accounting theory, policies and practice from the international perspective and viewpoint. The Journal editorial recognizes that international accounting is influenced by a variety of forces, e.g., governmental, political and economic. Thus, the primary criterion for manuscript evaluation is the incremental contribution to international accounting literature and the forces that impact the field. The Journal aims at understanding the present and potential ability of accounting to aid in analyzing and interpreting international economic transactions and the economic consequences of such reporting. These transactions may be within a profit or non-profit environment. The Journal encourages a broad view of the origins and development of accounting with an emphasis on its functions in an increasingly interdependent global economy. The Journal also welcomes manuscripts that help explain current international accounting practices, with related theoretical justifications, and identify criticisms of current policies and practice. Other than occasional commissioned papers or special issues, all the manuscripts published in the Journal are selected by the editors after the normal double-blind refereeing process.
