Aggregate Demand and Aggregate Supply

 

Economic activity fluctuates from year to year.

 

What is a Recession

 

What is a Depression

 

Model of Aggregate Demand and Aggregate Supply: the model that most economists use to explain short-run fluctuations in economic activity around its long-run trend.

                         Aggregate-Demand Curve: a curve that shows the quantity of goods and services that households, firms, and the government want to buy at each price level.

                         Aggregate-Supply Curve: a curve that shows the quantity of goods and services that firms choose to produce and sell at each price level.

 

3.         In this model, the price level and the quantity of output adjust to bring aggregate demand and aggregate supply into balance.

What factors cause the Short-Run Aggregate-Supply Curve to Shift

 

 

Where is the Long-Run Equilibrium

  

1.         Long-run equilibrium is found where the aggregate-demand curve intersects with the long-run aggregate-supply curve.

 

2.         Output is at its natural rate.

 

3.         Also at this point, perceptions, wages, and prices have all adjusted so that the short-run aggregate-supply curve intersects at this point as well.
