Are standard production network properties similar across all available datasets, and if not, why? We provide benchmark results from two administrative datasets (Ecuador and Hungary), which are exceptional in that they have no reporting threshold.

We compare these networks with a leading commercial dataset (FactSet) and published results on national firm-level production networks. Administrative datasets with no reporting thresholds have remarkably similar quantitative properties, while a number of important properties are biased in datasets with missing data.
