However, I still need to decide which one or both are endogeous, which
is a previous step of regression later. Only deciding the endogeneity
first can I decide the equation ultimately. Could you please give me
any suggestion ?
The results you present show that there is definitive evidence that
the equation should not be estimated by OLS, and that instrumental
variables techniques are required to achieve consistency. It is safest
to assume that both should be considered endogenous, as when both are
excluded you have problems.
