Abstract
This study investigates the impact of earnings management (EM) on agency costs (AC) in non-financial listed enterprises in Vietnam from 2011 to 2022. Utilizing the Generalized Method of Moments (GMM) to address endogeneity issues, the findings reveal that increased EM activity leads to higher AC. Additionally, the results highlight the significant influence of corporate governance mechanisms and internal enterprise characteristics on AC. Based on these findings, the paper provides policy recommendations for Vietnamese policymakers, as well as practical insights for investors and enterprise managers, to mitigate agency costs and enhance corporate governance practices
