"PRODUCTION"??? Did you say "production"?  It=B4s in its hidden abode, I  
presume. We are economists, Sir!. "Nous n'avons pas besoin de cette  
hypothese".  Of course, textbooks go on about Vinerian curves and  
Marshallian  empty boxes, sometimes providing estimates of minimum efficient  
scales as percentage of the industry, etc..  But production is not  
subjectivist enough.  Moreover, in the model just assume a convex set.  
[Non-convexity was introduced by Arrow & Hahn in their 1971 text with the  
Miltonian quote "A gulf profound as that Serbonian bog, Betwixt Damiata and  
Mount Cassius old, Where armies whole have sunk"].  In the unwieldy tome  
"Microeconomic theory" by MSG - the standard and technically superlative  
postgraduate textbook - the word "labor" does not appear in the index.  [It  
should have appeared between "Kuhn-Tucker conditions" and "Lagrange  
multipliers"].  My favourite though, is J Trout Rader's article in the New  
Palgrave: "Production as Indirect Exchange".  
As for Georgescu-Roegen, I think that the majority of postgrads think that  
he is the guy who invented X-rays.
