Approach: First get first stage of TSLS and get the residuals r. Then run a regression Y = β X + δ r and test if δ = 0. If significantly different, ( X 1, X 2) is not exogenous, and you should use TSLS, otherwise you can use the more efficient OLS. Note that unlike Wald test, the first stage and residuals ...
