Step-by-step explanation:
The principles of economic exchange in gatherer-hunter societies are based on principles of egalitarianism and sharing. In these societies, all members of the band share gathered and hunted foods equally, regardless of their value or interest in compensation. This form of exchange, known as generalized reciprocity, promotes equality and cooperation within the group. Stinginess and refusal to share are stigmatized and can result in gossip, ridicule, and even ostracism.
