Notwithstanding the enormous amount of regulation and standards governing the financial reporting process, corporate failures and prior research have strongly indicated that earnings management (EM) is becoming a regular business practice in most firms today. Although this practice is more common in developed economies, there is limited research on corporate governance (CG) failures that have occurred in East Africa’s emerging economies. In this study, therefore, we examine whether corporate governance mechanisms (CGM) moderate the association between corporate disclosure (CD) and EM using evidence from listed firms at the Uganda Securities Exchange (USE). We employ disclosure and corporate governance indices to measure the extent of CD and corporate governance. Additionally, we use the magnitude of discretionary accruals (DACC) obtained from the modified Jones model as a proxy for EM. We find that audit committee (AC) characteristics have a negative and significant moderating effect on the association between CD and EM. Our study contributes to the growing strand of literature on the moderating or complimentary effect of CGM in constraining EM in the context of an emerging economy.
