Summary
Aggregate supply (AS) represents the total output that firms are willing to produce at various price levels. There are differing perspectives on the long-run aggregate supply, with monetarists viewing it as vertical at full employment, while Keynesians depict it with three segments reflecting different economic conditions. Understanding these views is essential for analyzing macroeconomic policies and responses to issues like unemployment and inflation.
