As Alan, Andrew, Duncan and Gil  deal with  
what Roemer and Okishio said or did not say, 
we should not lose sight of Alan's point that 
Marx himself was not an adherent of "The 
Falling Equilibrium Rate of Profit."   Yet, the  
Okishio Theorem is often used as an answer 
to Marx's falling rate of profit.  The textual 
support for that position has yet to be seen. 
Rather it seems that given economists are  
comfortable with the idea of equilibrium, the  
notion of a falling rate of profit  as the economy 
traverses (somehow) from one equilibrium point  
to another is simply imputed to Marx.
