The Impact of Financial Rewards on the Quality and Effectiveness of Whistleblowing: A Systematic Literature Review
Main Article Content
Abstract
Purpose: The efficacy of financial incentives in motivating whistleblowers remains a subject of intense debate. While proponents argue that monetary rewards are essential to overcome the severe risks of reporting ("career suicide"), critics contend they may encourage frivolous claims and erode intrinsic moral motivation. This study systematically evaluates the impact of financial rewards on report quality, asset recovery effectiveness, and the critical moderating factors of whistleblowing success.
Design/methodology/approach: Guided by the PRISMA protocol, this Systematic Literature Review (SLR) analyzes 24 empirical and theoretical articles published between 2019 and 2026. The selected literature encompasses a global perspective, spanning developed frameworks (e.g., the US) and emerging economies (e.g., Nigeria, Indonesia, China), and utilizes diverse methodologies including archival data, experiments, surveys, and legal analyses.
Findings: The synthesis reveals that financial incentives function as a vital signal extraction mechanism, significantly enhancing report quality by attracting "insiders" who possess high-value, firsthand evidence. Incentive programs yield a high Return on Investment (ROI) through substantial asset recovery and ex-ante fraud deterrence. However, their success is strictly contingent upon structural moderators: robust anti-retaliation laws and guaranteed anonymity. In low-trust environments lacking these protective safety nets, financial rewards alone fail to mobilize reporting.
Practical implications: Policymakers and organizations should adopt percentage-based (qui tam) reward models to adequately offset insider risks. Crucially, these financial mechanisms must be underpinned by a strong "protection infrastructure," encompassing technical anonymity (e.g., encrypted channels) and strict penalties for false reporting to filter out noise.
Originality/value: This review contributes to the existing literature by integrating economic, legal, and behavioral perspectives to provide a holistic model of incentivized whistleblowing. It clarifies the conditional relationship between monetary rewards, whistleblower safety, and reporting behavior.
