And I hope you don't mind if I revive this thread so belatedly, I've been meaning to reply but buried under a mid-semester mountain.

I'd love to read it. I see from his CV he has quite a few early papers on portfolio theory, asset pricing and growth which I would like to get around to checking out, since I've been wading around in 1950s and 1960s mainstream monetary theory for my historical research and it would be interesting to see where he was coming from before he took the Marxian turn.

I like his take in his 1983 Social Concept paper, where he writes about the role of gold in Marx's theory of money and different ways of theorising the falling away of the gold link. I basically agree with his perspective - I think Marx had essentially a long-period theory of the value of money based on commodity/foreign exchange anchoring, and never had much of a need to talk about what happened in the short period - but it's the short-period that matters now the anchor is gone.

Yeah - I read an early draft of Graeber's book (or maybe a shorter version - it was a long essay) a couple of years ago and I was thinking about it again after his interview with Doug. I agree with your take. The same basic line (that money is in essence a creature of the State) is put in the opening chapter of Keynes' 'Treatise on Money'. Explaining the historical origins of money is not the same as explaining its present role in the capitalist system - it seems to me that much chartalist argument makes the mistake of thinking something's essence is determined by its origins. It's telling that Keynes' narrative jumps from Hannibal's crossing of the Alps to Napoleon's two millennia later - it elides the rise of capitalism and its long adaptation and transformation of the monetary system it inherited from feudal society. Not that Graeber makes the same elision, and he obviously has a lot of interesting things to say - but I can't abide chartalism!
