Notes: [1] The 10th quantile for CES-D score points to better mental health than the other four quantiles. [2] F-statistics for “NRPS duration at the county level” in the first stage are respectively 240.25 and 87.51 for NRPS enrollment and NRPS income. [3] The covariates are same as in Table 2. [4] ***, ** and * represent statistical significance at the 1%, 5% and 10% levels, respectively. Standard errors are reported in the parentheses.
