Foreign listings, corporate governance, and equity valuations

This paper analyzes the impact of foreign listing on equity valuations and relates it to an improvement in corporate governance. It documents abnormal returns around the announcement to list foreign shares on the London Stock Exchange. These are partially explained by a reduction of agency costs that is consistent with the enhanced monitoring and investor protection that prevail in a superior information and legal environment. The results are consistent with predictions derived from theoretical models of agency costs and illustrate an interesting implication of more open global equity markets.
