In this study we address the ongoing debate as to whether the competition among the world's major exchanges through simplified disclosure requirements is justified. Companies from across the globe have a choice of cross-listing shares as either American or Global Depositary Receipts (ADRs and...

This paper shows that improving financial efficiency may reduce real efficiency. While the former depends on the total amount of information available, the latter depends on the relative amounts of hard and soft information. Disclosing more hard information (e.g. earnings) increases total...
