Tiebout’s most famous article, “”A Pure Theory of Local Expenditures,”” analyzed the “”free rider problem”” that governments face when they provide goods and services. Tiebout’s key insight was that this problem is different when local governments provide goods to citizens who can move among distinct communities. If citizens are faced with an array of communities that offer different types or levels of public goods and services, then each citizen will choose the community that best satisfies his or her own particular demands.
