A Regression-Discontinuity Design Around a Food-Delivery App's Live-Tracking Cutoff
A paper from the School of Emergent Priorities treats a food-delivery app's fixed live-tracking radius as a natural experiment, finding that orders whose courier crosses the 400-metre trigger just before delivery carry tips averaging 2.1 percentage points higher than orders that don't, an effect unmoved by three bandwidths and two placebo cutoffs. The University's Facilities division has since written a minimum pin-visibility interval into its own campus food-delivery contract.
