International cross-listing and stock pricing efficiency: An empirical study

International cross-listing should subject stocks involved to ameliorated information environment in the host market, resulting in more information being revealed, fed back, and impounded into their prices at home and, thus, higher home-market pricing efficiency. Employing a simple non-parametric test, we present the first large-sample evidence for this hypothesis, and document that foreign cross-listings in the U.S. indeed enhance home-market stock pricing efficiency, net of marketwide efficiency shifts in the concurrent period. In addition, the efficiency benefit applies equally well regardless of home-market development status or cross-listing location. These findings should be of interest to both academics and practioners.
