Note: This table shows the marginal effects on service reliability and drinking water tangibles, respectively. The marginal effects of dummy variables depend on the discrete change from 0 to 1, while the marginal effects of continuous variables are evaluated at the mean values of the covariates. The results are based on the probit model in Table 4. All the variables are defined in Appendix Table 1 (available with the online version of this paper). *Significant at 10 percent level; **significant at 5 percent level; ***significant at 1 percent level.
