Understanding Aggregate Supply: Short Run vs. Long Run

TLDRAggregate supply is the total supply of final outputs in an economy at a given time. In the short-run, the aggregate supply curve slopes upward due to constant prices of labor and other inputs. In the long run, supply responds to changes in input prices. Sticky wage theory, sticky price theory, and misconceptions about relative prices explain the upward slope. Changes in input prices and technology can shift the aggregate supply curve.

Key insights

📈The short-run aggregate supply curve slopes upward due to sticky wages and prices.

In the long run, changes in input prices and technology can shift the aggregate supply curve.

💵Sticky wages and prices intensify the pressure on production caused by price fluctuations.

📊The short-run aggregate supply curve determines short-run economic behavior.

💡Misconceptions about relative prices can attribute to the upward slope of the aggregate supply curve.
