Abstract: | We empirically examine changes in information asymmetry and informational efficiency of cross‐listed stocks in their home market around a cross‐listing in the United States. We estimate intraday market microstructure measures of information asymmetry and price efficiency, and find that a U.S. cross‐listing significantly improves the quality of a firm's information environment and stock price efficiency in the home market. This improvement is stronger for cross‐listings that take place after the adoption of Sarbanes‐Oxley Act. Our results demonstrate that stricter disclosure from a U.S. cross‐listing is beneficial, in line with the legal and reputational bonding hypotheses. |
