Key research themes
1. How do audit committee characteristics influence the coordination and resource allocation between internal and external audit functions?
This research area investigates the dynamic interplay between audit committees and internal audit functions and how their characteristics influence audit quality, internal audit resourcing, and external audit fees. Understanding these relationships is critical due to the growing emphasis on corporate governance structures, where audit committees oversee both internal and external audit activities to enhance financial reporting reliability and auditor independence. The theme encompasses studies that empirically examine audit committee independence, expertise, diligence (meeting frequency), and tenure, and their impact on internal audit budgets and external audit fees, highlighting substitution and complementarity effects between internal and external audits.
2. What factors determine internal audit function effectiveness and its influence on corporate governance quality?
This theme focuses on understanding the determinants and conceptualizations of internal audit effectiveness and how internal audit contributes to enhancing corporate governance and risk management processes. It addresses the organizational, relational, procedural, and resource factors that affect internal audit function performance and independence, and evaluates their influence on audit committee and external auditor reliance. The theme includes frameworks and empirical insights on internal audit roles in public and private sectors, emphasizing the institutional and risk-based perspectives on internal audit function efficacy, independence, objectivity, and governance impact.
3. How does external auditor reliance on internal audit function vary with governance and control factors to influence audit quality and costs?
This theme explores the conditional reliance external auditors place on internal audit work, considering corporate governance quality, internal control effectiveness, and client business risk, and the implications for audit quality and economic outcomes such as audit fees. Experimental and empirical studies analyze how improved governance and internal controls enable greater substitution of audit efforts, leading to efficient audit processes. It also encompasses the role of coordination and cooperation between internal and external auditors, and how experiences with internal audit functions affect external auditor behavior.
