Audit quality, political connections and information asymmetry: evidence from banks in gulf co-operation council countries

Purpose The purpose of this paper is to investigate the impact of audit quality on information asymmetry for a sample of leading listed local banks in the Gulf Cooperation Council (GCC). In addition, the paper examines whether a firm's political connections moderate the association between audit quality and information asymmetry. Design/methodology/approach The author employs country fixed effects to examine the impact of audit quality on information asymmetry. The paper uses a sample of 49 leading listed local banks across the GCC and 236 bank-year observations, over the period of 2012-2016. Findings Using trading volume, trade value and stock return volatility as proxies for information asymmetry and audit quality through auditors' opinion and audit size, the paper documents that audit quality plays an important role in improving the quality of financial information reporting by providing greater independent assurance of the credibility of financial reports. The paper also documents that a firm's political connections have no effect on the association between audit quality and information asymmetry, indicating that the beneficial effects of audit quality are no greater for politically connected firms than for similar but politically unconnected firms. Practical implications The findings of the study help policymakers, standard-setters and regulators to understand the potential adverse effect of political connections on the role of audit quality on information asymmetry. The study also provides important insights for audit regulators to better identify and understand the benefits of audit quality and to take policy matters that influence audit quality seriously. Originality/value The study increases our understanding of the impact of audit quality on the level of information asymmetry in different economic, legal and political institutions, regulatory and litigation incentives and social contexts compared to that of research conducted using data collected from developed and other emerging countries. This will help to widen our knowledge on the role of audit quality on information asymmetry across the globe.
