Mike Miller is the town manager of Medfield, a town with 50,000 residents. At a recent town meeting, several citizens proposed building a large public swimming pool in the center of town for all of the residents to enjoy. A survey of all 50,000 residents revealed that the pool would be worth $50 to each of them. Because the cost to build the swimming pool is only $1,000,000, Manager Miller arranges to have the pool built. Everyone in town enjoys the pool, but when Manager Miller asks for donations to pay for the pool, he only collects $250,000. Manager Miller soon realizes thatA. the pool is a club good.B. the survey was conducted improperly.C. the cost of the pool exceeded the social benefits.D. most residents of the town are probably free-riders at the pool.
