Before revision:  We show in simulations that,  for important classes of networks lacking low-conductance clusters, cluster-robust methods can exhibit substantial size distortion , whereas for networks with such clusters, they outperform HAC estimators .
After revision:  We show in simulations that, when clusters have low conductance, cluster-robust methods outperform HAC estimators in terms of size control. However, for important classes of networks lacking low-conductance clusters, cluster-robust methods can exhibit substantial size distortion , whereas for networks with such clusters, they outperform HAC estimators .
