This study aims to provide empirical evidence about the determinants that can impact earnings management, through board diligence, ownership concentration, CEO ownership, and CEO tenure, as well as testing conservatism as a moderating variable. Secondary data, specifically information derived from annual financial reports, are utilized in this study. Information for financial reports is acquired from the Indonesia Stock Exchange (IDX) data stream and website from 2013 to 2022, the population of this study comprises all banking institutions listed on the Indonesia Stock Exchange. This study’s findings demonstrate that the presence of board diligence significantly hinders earnings management. Moreover, the findings of this study demonstrate that organizations characterized by a significant concentration of ownership will have the capacity to mitigate the prevalence of earnings management practices. Additionally, this study’s findings demonstrate that a reduction in earnings management activities is associated with greater CEO ownership. The findings of this study offer a practical illustration for stakeholders regarding the responsibilities of shareholders, which may prove beneficial in overseeing an organization’s operations. This study shows that high conservatism in companies actually mitigates the good effects of the ownership concentration and CEO ownership variables on earnings management. In summary, this study establishes that companies characterized by elevated levels of conservatism do not actively engage in earnings management practices that are beneficial to the organization.

Abstract
This study examines whether Environmental, Social, and Governance (ESG) performance enhances stock returns directly or indirectly through firm fundamentals in an emerging market context. The analysis focuses on non-financial firms listed on the Indonesian Stock Exchange (IDX) over the period 2014–2023, following the expansion of sustainability reporting regulations in Indonesia. The final sample comprises 4,037 firm-year observations, of which 477 contain available ESG scores obtained from a third-party rating database. Panel data regression models with firm-level controls and mediation analysis are employed to test both direct and indirect relationships. The empirical results indicate that ESG performance has a positive and statistically significant effect on total factor productivity (TFP) and return on assets (ROA), suggesting that sustainability practices are associated with improvements in operational efficiency and profitability. In turn, both TFP and ROA exhibit positive and significant effects on stock returns. However, ESG does not demonstrate a statistically significant direct effect on stock returns after controlling for firm fundamentals. Mediation analysis confirms that ESG influences stock returns indirectly through productivity and profitability channels, with productivity emerging as the stronger transmission mechanism. These findings suggest that, in the Indonesian capital market, ESG operates primarily as a fundamental value-enhancing mechanism rather than as an independent pricing signal. Sustainability performance contributes to shareholder value when it strengthens firms’ internal efficiency and financial resilience, highlighting the importance of fundamental performance channels in emerging markets.
