Previous studies have provided evidence of the effect that accounting regulation through the adoption of International Financial Reporting Standards (IFRS) has on the informational environment. However, none have investigated how this effect is driven. This study examines whether earnings quality is an effective channel through which the IFRS can mitigate the level of information asymmetry. Based on a sample of French listed companies, we find that information asymmetry decreases significantly after the adoption of IFRS. Using a path analysis and maximum likelihood estimations, the results show that the faithful representation component of earnings quality is the only channel through which IFRS decrease the level of information asymmetry. This finding suggests that the faithful representation of earnings increased under IFRS regulation, which, in turn, enhanced the quality of the informational environment. Our findings are robust using several sensitivity analyses.
