Abstract
In a model of banking we give money a role in providing cheap collateral; i.e. besides the Taylor Rule, monetary policy can affect the risk-premium by varying the supply of M0 in open market operations, so that even at the zero bound monetary policy is still effective, and fiscal policy still crowds out investment. A simple rule for making M0 respond to credit conditions can substantially enhance the economy’s stability. This, in combination with Price-level or nominal GDP targeting rules for interest rates, stabilises the economy further, making aggressive and distortionary regulation of banks’ balance sheets redundant.
