Quantity Theory of Money
Understanding the Relationship Between Money Supply and Economic Variables
Introduction to Monetary Theory
The Quantity Theory of Money (QTM) is a fundamental principle in monetary economics that establishes the relationship between the money supply in an economy and the level of prices of goods and services. First formalized by Irving Fisher in the early 20th century, this theory remains central to understanding inflation and monetary policy.
