We do not have sufficient data to construct reliable instrumental variables to correct for this potential bias. As long as we find hospital waiting time to be negatively correlated with hospital choice, this potential bias may not be a serious problem. 8 Patients' own previous experiences with ...

Lastly, although we have tried to minimize the possibility of endogeneity or reverse causality, further research could strengthen our results by using alternative approaches, such as the instrumental variables approach or the difference-in-difference methodology, to reinforce a possible causal effect ...
