Optimal Inference under Weak Identification
with Tetsuya Kaji. This project studies the optimality of inference methods in the general formulation of weak identification in semiparametric models, i.e., when a parameter is weakly regular. Under weak identification, standard methods usually fail to deliver valid inference. We formulate a class of inference procedures that are robust to weak identification. We show that by considering the quotient space of the underlying regular parameter space, the efficiency results of van der Vaart (1991) can be extended to our case.
