Short Description: A line graph of price level versus real G D P. Long Description: The vertical axis is labelled, price level (G D P deflator, 20 12 = 100) and ranges from 60 to 110 in increments of 10 with a kink near the origin. The horizontal axis is labelled, real G D P (billions of 20 12 dollars) and ranges from 450 to 700 in increments of 50 with a kink near the origin. The line for S A S is a concave up curve that slopes upward from the lower left corner to the upper right corner passing through the points (475, 60), (550, 70), and (600, 80). The line for A D slopes downward from the upper left corner to the lower right corner, passing through the points (550, 90), (600, 80), and (650, 70). The line for L A S is a vertical line from the point (550, 0) on the horizontal axis passing through the points (550, 70) and (550, 90).

Short Description: A graph of price level versus real G D P. Long Description: The vertical axis is labelled, price level (G D P deflator, 20 12 = 100) and ranges from 60 to 110 in increments of 10 with a kink near the origin. The horizontal axis is labelled, real G D P (billions of 20 12 dollars) and ranges from 320 to 520 in increments of 40 with a kink near the origin. The line for S A S slopes upward from the lower left corner to the upper right corner passing through the points (340, 70) and (400, 85). The line for A D slopes downward from the upper left corner to the lower right corner, passing through the points (360, 100), (400, 85), and (440, 70). The line for L A S is a vertical line from the point (440, 0) on the horizontal axis passing through the point (440, 70).
