Bottom line: we can always interpret OLS estimates as coefficients of BLP. The only question is whether BLP corresponds to conditional expectation E(y x).

Webmeasured the expected squared di erence between our estimator and the true value of .

This comes from the fact that convergence in probability does not imply convergence in mean without additional assumptions.

Webably not be close to θ. Our adjusted estimator δ(x) = 2¯x is consistent, however. We found the MSE to be θ2/3n, which tends to 0 as n tends to infinity. This doesn’t necessarily mean it is the optimal estimator (in fact, there are other consistent estimators with MUCH smaller MSE), but at least with large samples it will get us close to θ.
