Aggregate Demand Curve Definition

Published Dec 23, 2022

Definition of Aggregate Demand Curve

The aggregate demand curve is a graphical representation of the relationship between the total amount of goods and services demanded in an economy and the overall price level. That means it shows how the total demand for goods and services changes when the price level changes.

Example

To illustrate this, let’s look at a hypothetical economy with a population of 10 million people. In this economy, the aggregate demand curve is downward sloping. That means the total demand for goods and services decreases when the price level increases. Conversely, when the price level decreases, the total demand for goods and services increases.

Why the Aggregate Demand Curve Matters

The aggregate demand curve is an essential tool for understanding macroeconomic dynamics. It helps economists to analyze the effects of changes in the price level on the overall economy. For example, if the price level increases, the aggregate demand curve shows that the total demand for goods and services will decrease. This, in turn, can lead to a decrease in economic output and an increase in unemployment. Thus, the aggregate demand curve is a valuable tool for understanding the macroeconomic effects of changes in the price level.
