  1. *, **, *** represent the statistically significant at 10%, 5%, and 1% levels, respectively. Standard errors in () are adopted 2-way robust clustered at year and city levels. The figures in {} is the P statistics of Kleibergen–Paap rk LM test with the null hypothesis is the IV cannot be fully identified. The figures in [] is the critical value of Cragg-Donald Wald F test at 15% maximal IV size, proposed by Stock-Yogo (2005)112. MSE is shortened for Mean Square Error.
