Local economies?

the long version

"The Roman economy was operated significantly above subsistence level, with production being stimulated by both taxation and trade. Some regions became wealthy on the basis of exporting low-value agricultural products across the Mediterranean. In contrast, it has usually been assumed that the high costs of land transport kept inland regions relatively poor. This volume challenges these assumptions by presenting new research on production and exchange within inland regions. The papers, supported by detailed bibliographic essays, range from Britain to Jordan. They reveal robust agricultural economies in many interior regions. Here, some wealth did come from high value products, which could defy transport costs. However, ceramics also indicate local exchange systems, capable of generating wealth without being integrated into inter-regional trading networks. The role of the State in generating production and exchange is visible, but often co-existed with local market systems."--
