A) it's been presented as both. The example you pointedly ignored that I posted above is one such example.
B) It's not really that material. The story serves the same purpose either way - both in the above example and in, say, Stiglitz.
>it's necessary to clarify what the myth actually is and why it supposedly is so important for capitalism.
It is which is why Graeber did explain why it's important.
I thought you read the book?
>In a deleted comment you claimed you read it in Mankiw.
After writing that comment I double checked the 8th edition of the text to see if i remembered correctly and ctrl-f and found zero about barter in the whole book so I guess we both misremembered.
I cant honestly remember which econ textbook I read it in since it was 16 years ago, but I do know that I read it and believed it and there are plenty of other examples that can be found via google, so whatever.
Nobody thinks this is the mainstream consensus view, not even Graeber.
> The story serves the same purpose either way
> It is which is why Graeber did explain why it's important.
The whole thread is about why Graber's just-so explanations are wrong. And your arguments are materially different from what is actually in the text.
> I guess we both misremembered.
From The Principles of Macroeconomics, 3rd Edition. Chapter 15 - The Monetary System
> The social custom of using money for transactions is extraordinarily useful in a large, complex society. Imagine, for a moment, that there was no item in the economy widely accepted in exchange for goods and services.
> It's important to emphasize that this is not presented as something that actually happened, but as a purely imaginary exercise. "To see that society benefits from a medium of exchange" write Begg, Fischer and Dornbuch (Economics, 2oos), "imagine a barter economy. " "Imagine the difficulty you would have today," write Maunder, Myers, Wall, and Miller (Economics Explairzed, 1991) , "if you had to exchange your labor directly for the fruits of someone else's labor." "Imagine," write Parkin and King (Economics, 1995) , "you have roosters, but you want roses".
He quotes Stiglitz after this and remarks:
> Again this is just a make-believe land
Before claiming it's the same myth it's necessary to clarify what the myth actually is and why it supposedly is so important for capitalism.
> Yes, I obviously did read the book. I also used to believe the myth because I first read it in an undergraduate econ textbook.
In a deleted comment you claimed you read it in Mankiw. There it is most definitely presented as a thought experiment asking the reader to imagine the inconvenience of barter.
