We are pleased to share the first in a new series of short videos on the material cultures of payment, money, and debt. Through these short pieces, we aim to pair academic experts with objects from the human transactional archive, drawing on the collections of the Institute for Money, Technology and Financial Inclusion and others. We are thrilled to launch this experiment with a commentary by Keith Hart (Centennial Professor of Economic Anthropology, London School of Economics), who discusses a kina shell necklace from the IMTFI collection and its connections to the history of anthropological thinking about money, gifts, and exchange. As always, please let us know if you would like to get involved in our film series or in Transactions’ other initiatives.
