Marshall's notion of the representative firm can be read as a macro notion with some resemblance to Keynes' aggregative concepts. Keynes' notions of aggregate demand and aggregate supply are fashioned after Marshall's definitions of demand and supply. Keynes starts with the Marshallian...

In explaining economic phenomena, economic analysis concentrates on selected influences and fixes the host of other factors under a ceteris paribus clause. This view, which goes back to Alfred Marshall (1842-1924), is developed in the first part of the book. Aggregation is viewed as a particular...

This note comments briefly on Mehdad Vahabi's article on Alfred Marshall's concept of "Normal Value." It points out, in particular, the relationship between normality and equilibrium in the context of Marshall's moving equilibrium method.
