Short Description: A set of four graph of price level versus real G D P. Long Description: The vertical axis of each graph is labelled, price level and the horizontal axis is labelled, real G D P. The graph are as follows.(a) The line for S A S slopes upward from the lower left corner to the upper right corner. The line for A D slopes downward from the upper left corner to the lower right corner, intersecting the lines for S A S. The line for L A S is a vertical line from a point on the horizontal axis. The line intersect the lines for S A S and A D right to their point of intersection.(b) The line for S A S slopes upward from the lower left corner to the upper right corner. The line for A D slopes downward from the upper left corner to the lower right corner, intersecting the lines for S A S. The line for L A S is a vertical line from a point on the horizontal axis.

The line for A D slopes downward from the upper left corner to the lower right corner, intersecting the lines for S A S. The line for L A S is a vertical line from a point on the horizontal axis. The line intersect the lines for S A S and A D left to their point of intersection.

Figure 10.3.3

Refer to Figure 10.3.3, which shows the AS-AD model in which an economy is in four possible short-run macroeconomic equilibrium. In which of the graphs would we predict that eventually the price level will fall and real GDP will decrease, everything else remaining the same?

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).
