  1. ***, **, and * denote 1%, 5%, and 10% significance levels respectively; robust standard errors are reported in brackets; the group older than 50 years cannot be estimated because the sample size is too small; regard “senior high school/technical secondary school or below” as low education level, “junior college/bachelor degree” as medium level, “bachelor degree or above” as high level.
