Permutation-Enhanced Two-Stage Least Squares Estimation for Robust Endogeneity Analysis: A Systematic Methodological Review
Endogeneity is one of the basic problems in econometric modelling as conventional regression estimates may be inconsistent and the conclusions from these estimates may be erroneous. Two-Stage Least Squares (2SLS) is an existing Instrumental Variable (IV) solution, but it has a proven finite sample unreliability when th...
