DESCRIPTION:Researchers often ask how an intervening variable contributes 
 to observed group-based outcome disparities. Examples include the roles of
  education in generating gender wage gaps\, racial health disparities\, an
 d intergenerational income mobility. We introduce a new nonparametric deco
 mposition approach to put this enterprise on a firm causal footing. We mak
 e three contributions. First\, we introduce a previously overlooked dispar
 ity-generating mechanism\; second\, we show how to isolate three distinct 
 mechanisms under unstructured eﬀect heterogeneity\; third\, we develop m
 ultiply robust and semi parametrically efficient double/debiased machine l
 earning estimators with desirable properties. Empirically we show how coll
 ege graduation plays multiple and nearly countervailing causal roles in in
 tergenerational income mobility\, including via our newly discovered gener
 ative mechanism. Joint work with Ang Yu.\nSpeakers:\nFelix Elwert (Univers
 ity Wisconsin-Madison)
