[edit] Marginal utility

I have been rebuilding the article on Marginal utility, almost from the ground-up. —SlamDiego 22:34, 25 December 2006 (UTC)

Given your previous interest in the article on marginal utility, I note to you that I have now also done extensive editing of that on marginalism. It still has a stubby section on history, insofar as I did little more than copy-and-paste the History section from the article on marginal utility, but an article on marginalism more generally should discuss marginal physical product, as Marshall and his neoclassical successors rely upon diminishing returns to explain the supply schedule. —SlamDiego_←T 22:13, 3 July 2007 (UTC)
