The theory of endogenous money and the LM schedule

By Tom Palley. From the abstract:

Money is at the center of macroeconomics, which makes understanding the money supply central for macroeconomic theory. this paper presents the Post Keynesian theory of endogenous money supply and shows how it is fundamentally different from the conventional money supply theory. the conventional approach relies on the money multiplier and bank lending is invisible. Post Keynesian theory discards the money multiplier and focuses on bank lending which drives money creation. the paper emphasizes the structuralist version of Post Keynesian theory which retains Keynes’ liquidity preference theory of long term interest rates and also recognizes banks are subject to nancial constraints that limit their lending activities. the paper then shows how to derive the Lm schedule in an endogenous money economy, which is a necessary prelude to reconstructing the IsLm model.
