This paper analyzes the problem of weak instruments on identification, estimation, and inference in a simple … nonparametric model of a triangular system. The paper derives a necessary and sufficient rank condition for identification, based on … which weak identification is established. Then nonparametric weak instruments are defined as a sequence of reduced …
