Aggregate demand, aggregate supply, and the Phillips curve In the year 2027, aggregate demand and aggregate supply in the imaginary country of Aso-Kuju are represented by the curves AD2027 and AS on the following graph. The price level is currently 102. The graph also shows two potential outcomes for 2028. The first possible aggregate demand curve is given by the curve labeled ADA curve, resulting in the outcome given by point A. The second possible aggregate demand curve is given by the curve labeled ADB, resulting in the outcome given by point B.

Suppose the unemployment rate is 7% under one of these two outcomes and 5% under the other. Based on the previous graph, you would expect outcome B▼ to be associated with the lower unemployment rate (5%). If aggregate demand is high in 2028, and the economy is at outcome B, the inflation rate between 2027 and 2028…arrow_forwardWhat is the Phillips Curve?

- In the year 2020, aggregate demand and aggregate supply in the fictional country of Drooble are represented by the curves AD2020 and AS on the following graph. The price level is 102. The graph also shows two possible outcomes for 2021. The first potential aggregate demand curve is given by the ADA curve, resulting in the outcome illustrated by point A.
