A Breakdown of the Valuation Effects of International Cross‐listing*
利用双重股票样本，分解交叉上市对股价的影响来源，发现市场分割效应在经济意义上远大于约束控股股东效应，且两类股票流动性均显著提升。
Abstract It is well known that cross‐listing domestic stocks in foreign exchanges has significant valuation effects on the listed company's shares. Using a sample of firms with dual shares, we explore the differential effects of cross‐listing on prices and we are able to separate the different sources of the benefits of cross‐listing. These sources include market segmentation, liquidity, and the bonding of controlling shareholders to lower expropriation of firm resources. Our results show that even though the market segmentation and bonding effects are both statistically significant, the economic significance of segmentation is more than double that of bonding. Furthermore, we document an economically and statistically significant increase in the liquidity of both share classes after the listing. Overall, our results explain why less and less firms are willing to list in the USA: Sarbanes Oxley has increased the cost of adopting better governance while its benefits are not substantial; and market segmentation has decreased significantly in the last years.
