The Reward Line

A Matched-Flyer Field Trial of Tip-Off Call Volume and an Audit of the Neighbourhood Noticeboard Reward-Tier Schedule

A paper from the School of Continuous Improvement reports a six-week matched-flyer field trial across 35 residential streets, comparing tip-off call volume for lost-pet flyers stating a reward against otherwise identical no-reward flyers, and benchmarking the University's own Neighbourhood Noticeboard Reward-Tier Schedule against the observed dosage-response curve. Stating any reward raised the weekly probability of a tip-off call by 15.2 percentage points, but the Schedule's predicted call-volume curve --- which climbs steeply from $20 to $200 --- diverges sharply from observed data above $50, with the two highest tiers ($100 vs $200) statistically indistinguishable.
