Resumen de Competition among exchanges through simplified disclosure requirements: : evidence from the American and Global Depositary Receipts

Oksana Kima, Matt Pinnuckb

• 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 GDRs, respectively). The former are primarily listed on the US exchanges � NYSE, NASDAQ and AMEX � whereas the latter are issued into non-US markets such as the London Stock Exchange (LSE). The GDRs listed on the LSE are subject to simplified disclosure requirements compared to their exchange-listed ADR peers that have to meet more stringent compliance standards. Proponents of the �light touch� approach argue that firms cross-listing as GDRs are not subject to the higher reporting costs faced by ADRs yet still face similar valuation benefits. Those who challenge this approach argue that simplified disclosure requirements set by the LSE will ultimately be recognised by the market as ineffective, diverting traders from investing in GDRs. This study provides evidence that supports the LSE's �light touch� approach and shows that the benefits of information risk reduction for ADRs and GDRs are comparable. The explanation for this finding is that the two avenues through which information asymmetry is expected to be resolved after cross-listing � disclosure and analysts � are substitutive and make equally important contribution to information risk reduction, eventually leading to similar cost of capital decline for ADRs and GDRs.
