distribution and exchange

[Wolff-Michael Roth <mroth@uvic.ca>]

Hi,
I had some trouble with remembering where in YE's triangle go the terms 
DISTRIBUTION and EXCHANGE. Today I realized for the first time that YE 
used to have EXCHANGE in the S-C-RULES subtriangle but on the website 
has it in the C-O-DivLab subbtriangle.
	Does anyone have an idea when this change happened and why it happened?
	Has anyone worked on the fact whether it made sense to overlay 
production-consumption-exchange-distribution, which Marx discussed at 
the society level onto YE's triangle, which deals with any local, 
concretely realized activity?
Thanks for any pointers.
Michael
