Quantity Theory of Money Mechanism in Monetary Economics
The Quantity Theory of Money posits a direct proportional relationship between the money supply and the general price level within an economy characterized by stable velocity and output in the long run. Formally expressed through the equation of exchange ($MV = PY$), this mechanism asserts that changes in nominal monetary aggregates translate directly into inflation when real variables are fixed, establishing money as a neutral variable regarding relative prices. This theory serves as a foundational pillar in classical and neoclassical macroeconomics, specifically delineating the transmission channel between central bank policy interventions and aggregate purchasing power erosion.
