How spending growth dictates the relationship between inflation and economic expansion

This video explains the aggregate demand curve, a core component of the AD-AS model used to analyze business cycles. By applying the dynamic quantity theory of money, you will learn how to map the trade-off between price increases and real economic growth.

The aggregate demand curve represents every potential pairing of inflation and real economic growth that aligns with a set rate of spending growth. To visualize this, the model plots inflation vertically and real growth horizontally.

The framework relies on the dynamic quantity theory of money, expressed as M + v = P + Y. Understanding this curve is a prerequisite for exploring the long-run aggregate supply curve and gaining a deeper grasp of economic fluctuations.
