| These common influences create the problem of endogeneity or selection, which may explain the influence of social control on runaway risk. |
| We also tested for endogeneity between the dependent variable and the explanatory variables. |
| Further research will need to determine whether these results are influenced by the potential endogeneity of the explanatory variables. |
| The average treatment effect estimation adopted in this study is designed to address this type of the endogeneity problem. |
| This approach tends to throw away information, while not solving endogeneity problems. |
| On a technical note, it was pointed out that using the size stock instead of changes may help address endogeneity problems. |
