Monetary Aggregates Definition And Diagram

In finance and economics we recognize several types of money. Monetary aggregates are used to measure the supply of various types of money in an economy. The most commonly used aggregates are M0 through M3, plus monetary base. See the following diagram to understand how the aggregates relate to each other.
