Survey on statistical inferences in weakly-identified instrumental variable models

This paper provides a brief review of the current state of knowledge on the topic of weaklyidentified instrumental variable regression. We describe the essence of the problem of weak identification, possible methods for detecting it in applied work as well as methods robust to weak identification. Special attention is devoted to the question of hypothesis testing in the presence of weak identification.
