At marginal revolution, Alex Tabarrok has a great post about a Detroit school.
That's cool but what I really like is this:
After the Christmas break, Knoper said the paycheck curriculum will be ramped up a notch when the kids start paying taxes on the hallways (a form of road tax) and playgrounds.
I know when my parents started offering me money when i made the honor roll in 3rd grade, i started making the honor roll very quickly and continued to do it. Once i got into high school, i still did it even though the money i got was about the same as the money i got in 7th grade, but i did if for different reasons then. So i think this is a great idea, and hope that it goes well.
