The radical anthropologist was that rare figure: a scholar who was also an activist.
In the third edition of the college-level textbook Macroeconomics, the economists Andrew Abel and future Federal Reserve Chairman Ben Bernanke blithely assert that “since the earliest times almost all societies … have used money.” They say that money arises from the inefficiency of barter—of trading one good for another—because “finding someone who has the item you want and is willing to exchange that item for something you have is both difficult and time-consuming.”
The evolution from barter to money is an old story in economics, repeated down the centuries in one form or another, to the point that even children are aware of it. It also happens to be only that: a story, and one with precious little evidence to back it up outside the heads of those who tell it.
While some economists imagine primordial villages and basic agricultural systems where birds are exchanged for flowers to illustrate the history of money, Abel and Bernanke come up with something much more immediate: The economist is hungry.
