What is 'Aggregate Demand' Aggregate demand is an economic measurement of the sum of all final goods and services produced in an economy, expressed as the total amount of money exchanged for those goods and services. Since aggregate demand is measured through market values, it only represents total output at a given price level, and does not necessarily represent quality or standard of living.
Defintion: Aggregate supply is the total of all goods and services produced by an economy over a given period. When people talk about supply in the U.S. economy, they are usually referring to aggregate supply. The typical time frame is a year. That time frame is important because supply changes more slowly than demand.
