Now show the long-run impact of the economic prosperity abroad by shifting both the aggregate demand (AD) curve and the short-run aggregate supply (AS) curve to the appropriate positions. 240 AS 200 AD 160 AS 120 80 AD 40 200 400 600 800 1000 1200 OUTPUT (Billions of dollars) PRICE LEVEL

The Greek letter a represents a number that determines how much output responds to unexpected changes in the price level. In this case, assume that a = $2 billion. That is, when the actual price level exceeds the expected price level by 1, the quantity of output supplied will exceed the natural level of output by $2 billion. Suppose the natural level of output is $50 billion of real GDP and that people expect a price level of 110. On the following graph, use the purple line (diamond symbol) to plot this economy's long-run aggregate supply (LRAS) curve. Then use the orange line segments (square symbol) to plot the economy's short-run aggregate supply (AS) curve at each of the following price levels: 100, 105, 110, 115, and 120. PRICE LEVEL 125 120 115 110 105 100 95 90 85 80 75 0 10 20 ☐ 30 40 50 60 70 OUTPUT (Billions of dollars) 80 90 100 -0- AS LRAS (?) The short-run quantity of output supplied by firms will fall short of the natural level of output when the actual price level level…
