1. Central banks provide reserves to the commercial banking system at some penalty rate. However, this compromises their capacity to control bank lending and target a given monetary policy rate.

5. Premium Question: Assume that inflation is stable, there is excess productive capacity, and the central bank maintains its current interest rate target.
