Good question.  I had presumed that it was in Pigou's 
_Economics of Welfare_, 1922, but I could not find it in 
there.  It does not seem to be in my copy of Marshall 
either, nor does it appear in Schumpeter's 1954, _History 
of Economic Analysis_, nor even in Richard Musgrave 
standard pub fin text from 1959, _The Theory of Public 
Finance_.  I have even scanned Coase's famous 1961 article, 
"The Problem of Social Cost" and do not see it even there.  
I note that he and Pigou are concerned with "divergences 
between private and social marginal product," which we 
would now claim to be due to externalities.  But as near as 
I can tell, neither uses the term.
     So, anybody out there know who did introduce this term 
into standard economics?  I doubt they got it from Marx, 
but who knows?
