I have a new post up at the Jacobin, responding to Mike Beggs' critical review of David Graeber's Debt. It's a much longer, and hopefully more convincing, version of some arguments I was having with Mike and others over at Crooked Timber last month. Mike things there is no useful economics in Debt; I think that on the contrary, the book fits well with important strands of heterodox economics going back to Marx and Keynes (not to mention Schumpeter and Wicksell).
In particular, I think the historical and anthropological material in Debt helps put concrete social flesh on two key analytic points. First, that we need to think of capitalism primarily organized around the accumulation of money, with economic decision taken in terms of money flows and money commitments; not as a system for the mutually beneficial exchange of goods. And second, within capitalism, we can distinguish between economies where the medium of exchange is primarily commodity or fiat money, and economies where it is primarily bank-created credit money. Textbook economic analysis tends to work strictly in terms of the former, but both kinds of economies have existed historically and they behave quite differently.
(There's a lot more in the book than this, of course, but what I am trying to do -- I don't know how successfully -- is clarify the points where Debt contributes most directly to economics debates about money and credit.)
If this sounds at all interesting, you should first read Mike's review, if you haven't, and then read my very long response.
... and then, you should read all the other great stuff at The Jacobin. For my money, it's the most exciting new political journal to come along in a while.
