Notes:$M=2491$⁠, $N=14,029$⁠, $A¯=0.45$⁠. The first column corresponds to the OLS estimator without fixed effects, and the second one—to the OLS estimator with fixed effects. The third column corresponds to the IPW estimator using the propensity score estimated by random forest, restricted to groups where the estimated score lies in $[0.05,0.95]$⁠. The final column corresponds to the doubly robust estimator with the same propensity score model. The standard errors are robust to heteroscedasticity and within-group correlation. This simulation is conducted using x86-64 architecture. The results we get using Apple M1 Pro chips differ slightly. Using the latter, we get for the IPW estimator 2.58 with an S.E. of 0.65, and for the doubly robust estimator 3.50 an S.E. of 0.45. These results are reported as a part of the replication package.
