Real Interest Rate (r)

The nominal interest rate adjusted for inflation; reflects the real cost of borrowing.

Crowding Out Effect

Monetary Base

The total amount of a currency in circulation or in the central bank's reserves.

Velocity of Money (V)

The rate at which money is exchanged in the economy; how many times a unit of currency is spent in a given period.
