‚ÄčMonte Carlo Confidence Sets for Identified Sets
(w/ X. Chen and E. Tamer)
revise and resubmit at Econometrica
It is often hard to determine whether parameters in nonlinear econometric models are point identified. We provide computationally attractive procedures to construct confidence sets for identified sets of parameters and subvectors by Monte Carlo simulations from a quasi-posterior. To justify our procedures, we establish new Bernstein-von Mises theorems for the posterior distribution of the QLR and profile QLR under partial identification.
