The Money Multiplier: How Banks Operate In The Land of Make Believe
M = 1/RR
A simple little equation. It says that the money multiplier (M) equals one divided by the reserve requirement (RR). For those of you mathematically inclined, it says that the money multiplier is the inverse of the reserve requirement. This cute little equation and the concept that it describes is taught to economics students. You will find a description of the concept in most Economics 101 textbooks and much like the Energizer Bunny, the teaching and reinforcement of money multiplier in the minds of students goes on and on and on throughout their undergraduate career. By the time they enter graduate school, they are “firm believers” in the holy word of the Church of Economic Nonsense.
