A Regression-Discontinuity Estimate at a Pizzeria's Felt-Pen Delivery Line
A regression-discontinuity study of the felt-pen free-delivery line on a strip-mall pizzeria's window map finds that households just inside it order 0.78 more times per household-year than households just outside, with no change in delivery time, basket size or cold-arrival complaints. It reports the Review Cadence Observatory's Catchment Standing Order, which draws every University consultation's catchment at the line's mean radius, in felt pen, with no override.
