We examine the effect of information asymmetry on equity prices in the local A‐ and foreign B‐share market in China. We construct measures of information asymmetry based on market microstructure models, and find that they explain a significant portion of cross‐sectional variation in B‐share discounts, even after controlling for other factors. On a univariate basis, the price impact measure and the adverse selection component of the bid‐ask spread in the A‐ and B‐share markets explains 44% and 46% of the variation in B‐share discounts. On a multivariate basis, both measures are far more statistically significant than any of the control variables.
