MCCALLUM RULE

A monetary policy development guideline developed by American monetary economist Bennett T. McCallum. This economic rule depicts the relationship of inflation and growth in the money supply that is necessary for creating a specific level of inflation. Significant inputs in the model are the projected inflation rate and long-term average rate of growth (in real GDP). It can also be used to justify and modify monetary policies by central banks to heat up the economy when it slowed down.
