"No ethnographic studies have shown that any present or past society has used barter without any other medium of exchange or measurement, and anthropologists have found no evidence that money emerged from barter. They instead found that gift-giving (credit extended on a personal basis with an inter-personal balance maintained over the long term) was the most usual means of exchange of goods and services. Nevertheless, economists since the times of Adam Smith (1723–1790) often inaccurately imagined pre-modern societies as examples to use the inefficiency of barter to explain the emergence of money, of "the" economy, and hence of the discipline of economics itself."
