approximate sparsity of the spatial weights matrix. The proposed estimation methodology exploits the Lasso estimator and mimics … two-stage least squares (2SLS) to account for endogeneity of the spatial lag. The developed two-step estimator is of more … variables is larger than the number of observations. We derive convergence rates for the two-step Lasso estimator. Our Monte …
