Treats are a supply price; they help get kids out trick or treating. Replacing candy with cash might bring out a small extra crowd of five year olds. It would bring out a very large extra crowd of teenagers. I want five year olds in clever costumes on Halloween nights. I do not want 17 year olds sans costumes at my door.I hear the same gripe on this side of the pond. What's with the high-schoolers in hoodies going "trick-or-treating?"
GETTING THE INCENTIVES RIGHT. In-kind, rather than cash, treating is efficient on Hallowe'en, notes Bill Sjostrom.
