Technological progress and the liberalization of capital flows have both contributed to the considerable changes in global equity markets over the past few decades. Yet obstacles to international capital flows still exist, leading to segmentation of markets and creating incentives for corporate managers to adopt financial policies such as international cross-listing. In exploring the costs and benefits of cross-listing, Chouinard and D'Souza find that U.S. exchanges are attracting an increasing share of cross-listed firms. The empirical studies they review suggest that the cost of equity capital declines following a foreign listing as a result of lower transactions costs or an improvement in the quality and quantity of firm-specific information available to investors. As well, informational asymmetries across countries prevent simultaneous price discovery across exchanges.
