Professional Ethics and Auditor Performance: The Moderating Role of Organizational Culture

Abstract

The increasing complexity of contemporary business environments has intensified the demand for high-quality auditing practices that enhance financial reporting credibility and stakeholder confidence. Professional ethics remains a fundamental pillar of auditing because auditors are expected to exercise integrity, objectivity, professional competence, confidentiality, and due care when performing their responsibilities. However, ethical principles alone may not always translate into superior audit outcomes, as auditors operate within organizational environments that influence their attitudes, decisions, and professional behaviours. This study examines the relationship between professional ethics and auditor performance and investigates the moderating role of organizational culture in strengthening this relationship. Drawing on agency theory, ethical decision-making theory, and social learning theory, the study proposes that auditors with stronger ethical orientations demonstrate improved audit performance through enhanced professional judgment, greater compliance with auditing standards, and improved audit quality. Furthermore, the study argues that an ethical and supportive organizational culture provides an enabling environment that reinforces ethical practices and amplifies the positive effects of professional ethics on auditor performance. Using a quantitative research approach, the study employs survey data collected from professional auditors and applies regression-based moderation analysis to examine the proposed relationships. The findings are expected to provide insights into how ethical values and organizational characteristics jointly influence auditor effectiveness. The study contributes to auditing literature by demonstrating that auditor performance is not only determined by individual ethical attributes but also by the organizational context within which ethical decisions are made.
