COMPARING PER CAPITA INCOME IN THE HELLENISTIC WORLD: THE CASE OF MESOPOTAMIA

Until quite recently, GDP growth between ca. 1 ce and the late Middle Ages was considered non‐existent or even negative. Recently, largely on account of increasing interest in historical national accounting, the late‐medieval figures have been revised upward, in line with an upward adjustment in the estimated shares of manufacturing and pasture. Leaving GDPs dating from the ancient world unaltered would consequently generate figures indicating increased economic growth during the first millennium ce . A considerable number of studies of the late‐medieval period (the object of increasing attention on the part of specialists in early economic history) have caused estimates for the ancient one to be revised upwards, essentially leaving estimates of the changes in economic development over time unaltered. These studies, however, have focused on the Roman Empire and Italia while there is a consensus in the literature that it was quite unrepresentative of all ancient societies with its relatively high share of GDP from the manufacturing sector of the economy. We therefore estimate a new per capita income for another contemporary agrarian society: ancient Mesopotamia. In addition, by examining manufacturing and pasture—the two main reasons for higher income which have been identified in the literature—we have found a tentative explanation for the fact that ancient Mesopotamia's per capita income deviated from that of Rome.
