The Exact Mean of the Two-Stage Least Squares Estimator of the Structural Parameters in an Equation Having Three Endogenous Variables
A. L. Nagar, Aman UllahThis paper deals with the two-stage least squares (2SLS) estimator of structural parameters in a system of M linear structural equations. The structural equation being estimated consists of three endogenous variables and some exogenous variables. The exact mean of the 2SLS estimator has been worked out.
