THE IMPACT OF INTERNATIONAL LISTINGS ON RISK - IMPLICATIONS FOR CAPITAL-MARKET INTEGRATION

In this paper, we examine the impact of international listing on common-stock risk. While previous research has used event study methodology, our research focuses on permanent shifts in risk. Different measures of risk are estimated to test for intertemporal shifts in risk attributable to an overseas listing. No significant shifts in risk from international listing are documented. The results are robust with respect to the location and year of listing. These findings suggest that: (1) markets are already reasonably well integrated; or (2) listing is an ineffective mechanism for reducing segmentation. © 1990.
