Charles Mills Tiebout (/tiˈboʊ/ "TEE-bow") (1924–1968) was an American economist and geographer most known for his development of the Tiebout model, which suggested that there were actually non-political solutions to the free rider problem in local governance. He earned recognition in the area of local government and fiscal federalism with his widely cited 1956 paper “A Pure Theory of Local Expenditures”.
