Estimating Gender Disparities in Federal Criminal Cases

This paper assesses and decomposes gender disparities in federal criminal cases. It finds large unexplained gaps favoring women throughout the sentence length distribution, conditional on arrest offense, criminal history, and other pre-charge observables. Decompositions show that most of the unexplained disparity appears to emerge during charging, plea-bargaining, and sentencing fact-finding. The approach provides an important complement to prior disparity studies, which have focused on sentencing and have not incorporated disparities arising from those earlier stages. I also consider various plausible causal theories that could explain the estimated gender gap, using the rich dataset to test their implications.
