Law of one price continues to be a central tenet of Financial Economics. This book is devoted towards examining law of one price in the context of dually-listed shares of Indian companies. Put simply, this book delves on the relationship between the prices of domestic shares issued by Indian companies and the prices of foreign shares issued by the same companies. It also examines the evolving uncertainty in relationships between such dually-listed shares issued by Indian companies. It draws upon the insights that we garnered over the years while working on technical papers in this area. The book, thus, undertakes concerted efforts to present facts in a manner that sensitise and meaningfully inform readers of the prevalent breadth and depth of dual-listing (cross-listing) landscape globally and more so, locally (India).
