Georgism, in modern times also called Geoism, and known historically as the single tax movement, is an economic ideology holding that persons should own the value that they produce themselves, while the economic rent derived from land—including from all natural resources, the commons, and urban locations—should belong equally to all members of society. Developed from the writings of American economist and social reformer Henry George, the Georgist paradigm seeks solutions to social and ecological problems based on principles of land rights and public finance that attempt to integrate economic efficiency with social justice.
