Two-sample instrumental variables estimators

Archived Abstract of Former PSC Researcher

Inoue, Atsushi, and Gary Solon. 2005. "Two-sample instrumental variables estimators." NBER Technical Working Paper No. 311Cambridge, MA : National Bureau of Economic Research.

Following an influential article by Angrist and Krueger (1992) on two-sample instrumental variables (TSIV) estimation, numerous empirical researchers have applied a computationally convenient two-sample two-stage least squares (TS2SLS) variant of Angrist and Krueger's estimator. In the two-sample context, unlike the single-sample situation, the IV and 2SLS estimators are numerically distinct. Our comparison of the properties of the two estimators demonstrates that the commonly used TS2SLS estimator is more asymptotically efficient than the TSIV estimator and also is more robust to a practically relevant type of sample stratification
