Abstract: |
We use longitudinal data on stock prices of cross-listed firms to investigate
abnormal systematic changes in the price disparity of cross-listed stocks
between the Hong Kong and Shanghai exchanges from 2002 to 2014. We identify a
liberalization policy that generated an unprecedented abrupt convergence in
price disparity. The policy, known as Shanghai-Hong Kong Stock Connect, serves
to lower the capital control barrier of cross-market investment between both
markets. In a quasi-experimental setup, we find that the announcement of the
policy caused the price disparity between cross-listed shares in both markets
to reduce by one-sixth. The magnitude of the effect was the largest since
2002, and was seven standard deviations away from the historical average. We
also find that the convergence was asymmetric, and the convergence was driven
by an upward revaluation of share prices. |
