In a traditional economy, land and capital are in common possession, and the main economic problems of society - what, how, and for whom to produce - are solved mainly on the basis of traditional tribal or semi-feudal hierarchical relations between people. The traditional economy is based on backward technology, the dominance of manual labor, and agricultural production.
