Economists treat barter as an inefficient alternative to market exchange, assuming that it is normal only in primitive economies. For their part, anthropologists are more concerned with the social and moral complexities of the "gift," and treat barter as mere haggling. The authors in this collection do not accept that barter occupies a residual space between monetary and gift economies. Using accounts from different parts of the world, they demonstrate that it is more than a simple and self-evident economic institution. Barter may constitute a mode of exchange with its own social characteristics, occupying its own moral space. This novel treatment of barter represents an original and topical addition to the literature on economic anthropology.
