On 28th November OxTalks will move to the new Halo platform and will become 'Oxford Events' (full details are available on the Staff Gateway).
There will be an OxTalks freeze beginning on Friday 14th November. This means you will need to publish any of your known events to OxTalks by then as there will be no facility to publish or edit events in that fortnight. During the freeze, all events will be migrated to the new Oxford Events site. It will still be possible to view events on OxTalks during this time.
If you have any questions, please contact halo@digital.ox.ac.uk
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, and intergenerational income mobility. We introduce a new nonparametric decomposition approach to put this enterprise on a firm causal footing. We make three contributions. First, we introduce a previously overlooked disparity-generating mechanism; second, we show how to isolate three distinct mechanisms under unstructured effect heterogeneity; third, we develop multiply robust and semi parametrically efficient double/debiased machine learning estimators with desirable properties. Empirically we show how college graduation plays multiple and nearly countervailing causal roles in intergenerational income mobility, including via our newly discovered generative mechanism.
