But I have, for the most part, resisted the temptation to point out the differences of view, preferring to let you the listeners infer them from my exposition of my own theories. It will suffice to remark at the outset that I clearly do not subscribe to the prevalent view that what the central bank does is to control the money supply, which in turn determines money income and prices. I would say instead that the central bank controls some short-term money-market interest rates and/or reserve aggregates and that these variables simultaneously affect other interest rates and financial quantities, GNP expenditures, and monetary aggregates.

I refer particularly to the attention I shall give in the second and third parts of the paper to credit, as distinct from money, i.e., to the asset, as well as the liability, accounts of commercial banks and other intermediaries. The first section concerns the link between asset valuations and capital spending. The second
