Chapter Six and its Appendix deal in some detail with the way Keynes is defining income, savings and investment in the General Theory while the appendix to Chapter 6 goes into detail on user cost. His concept of user cost at one point sparked a certain amount of controversy among Keynesians but has since virtually been forgotten. It is of interest to us because user cost is the place where Keynes sees firms taking account of the future consequences of their current production decisions. The General Theory is a theory of the short run, but firms’ cost curves, which are key to many short run decisions, contain a forward looking element. Chapter 7 returns to the concepts of saving and investment, relates Keynes’ definitions to those used by others (including his own from the Treatise) and relates aggregate investment, which refers to additions to physical capital stock, to the way the term is often used at the micro level, in the sense of investment in financial assets.
