Using firm‐level data from 23 developed markets, we document a positive association between overall firm‐level governance quality and the informativeness of earnings announcements measured by abnormal stock return variance. This finding is robust after controlling for the potential endogeneity of firm‐level corporate governance. Further analyses reveal that firms with strong governance show little evidence of earnings management, appoint Big 4 auditing firms, and attract analyst following, implying a positive link between strong corporate governance and the information quality of earnings announcements. Finally, there is some evidence that the relation between firm‐level governance and market reactions around the announcements exists only in countries characterized by a transparent information environment and strong legal investor protection.

This article examines whether foreign investor heterogeneity plays a role in stock liquidity in a sample of 27,828 firms from thirty-nine countries worldwide. Foreign direct ownership is negatively associated with stock liquidity, while foreign portfolio ownership is positively associated with stock liquidity. Consistent with theoretical predictions, foreign ownership explains stock liquidity through both trading activity and information channels. The value-enhancing benefits of foreign direct investors’ monitoring efforts outweigh their liquidity costs and high adverse selection premium. However, the positive impact of foreign portfolio ownership on firm performance becomes negative and is not robustly significant after controlling for liquidity.
