Under treatment effect heterogeneity, an instrument identifies the instrument-specific local average treatment effect (LATE). If a regression model is estimated by the two-stage least squares (2SLS) using multiple instruments, then 2SLS is consistent for a weighted average of different LATEs. In...

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 …
