Synchronous Price Discovery of Cross-Listings

Abstract

Extending from Grossman and Stiglitz (1980), we provide an asset pricing model of a synchronously traded crosslisted pair under information asymmetry. Following Garbade and Silber (1983), the model further embraces multimarket price discovery in a dynamic framework. The implications are as follows: The price sensitivity of holdings is higher for informed traders than for uninformed traders; the largest cross-border price spread occurs in the absence of arbitrageurs; price discovery is more likely in markets with a larger population of informed traders; and parity convergence accelerates with a higher price elasticity of demand of arbitrageurs.
