Endogeneity in quantile regression models: a control function approach [PDF]

, 2004
This paper considers a linear triangular simultaneous equations model with conditional quantile restrictions. The paper adjusts for endogeneity by adopting a control function approach and presents a simple two-step estimator that exploits the partially ...
