John, I suspect that you may be unduely complicating
the issue of price rises by discussing them in the
more general context of crises. Before we get to that
we have to asses the validity or otherwise of Marx's
criticisms of Ricardos quantity theory.
These are posed at the level of commodity circulation
rather than the aggregate circulation of capital. I
would suggest that it is simpler to follow Marx and
try to look at it at this level first.
