This document provides an overview of key concepts in aggregate demand and aggregate supply analysis including:
- The aggregate demand curve is downward sloping due to the real-balances, interest-rate, and foreign purchases effects. The aggregate supply curve has three segments: horizontal, upward-sloping intermediate, and vertical.
- Equilibrium output and price levels occur at the intersection of the aggregate demand and supply curves. A shift in either curve results in a new equilibrium.
- Determinants that influence aggregate demand and supply are discussed, such as consumer spending, investment, government spending, net exports, input prices, and productivity.
- Examples are given of how changes in aggregate demand or supply can cause inflation
