The effect of mandatory IFRS adoption on real and accrual-based earnings management activities

This study examines the effect of mandatory adoption of International Financial Reporting Standards (IFRS) on both accrual-based and real earnings management. While prior literature has mainly examined the effects of IFRS adoption on accrual-based earnings management, no study to date has focused on the impact of IFRS adoption on real earnings management. Using a sample of 15,206 observations from 22 European countries between 2000 and 2010, this study employs a control sample of voluntary adopters and applies a differences-in-differences design to control for confounding concurrent events. The results suggest that mandatory IFRS adoption had no significant impact on either real or accrual-based earnings management practices. Additional analysis on a sub-sample of firms with relatively strong earnings management incentives supports a dominant role for firm-level reporting incentives over accounting standards in shaping financial reporting quality.
