In econometrics some nonparametric instrumental regression models and nonparametric demand models with endogeneity lead …

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 …

The increasing availability of retail scanner data makes it possible to study consumer demand at more disaggregated …SLS) estimator and applies it to estimate a quadratic almost ideal demand (QUAID) system with 47 fruits and vegetables … with endogenous prices. Even for a large demand system, the I3SLS is shown to be computationally simple. Then we calculate …
