摘要：

The Split-Share Structure Reform in China mandated the conversion of nontradable local A-shares into tradable status and increased A-share float. This paper examines the long-term pricing effects of the increased float. Given that foreign B-shares were not directly affected by this reform, we use B-share price to control for possible changes in firm fundamentals. We find that, across firms, larger increase in float leads to larger decrease in A-share price relative to B-share price, even up to around ten years after the reform, suggesting that demand curves slope down in the long run. Consistent with the theory based on heterogeneous beliefs, we find that a larger increase in float leads to lower turnover and lower volatility, and that demand curves are more downward-sloped when divergence of opinion is larger. We also find evidence that arbitrage risk prevents arbitrageurs from flattening the demand curves.
