The following graph plots aggregate demand (AD2027AD2027) and aggregate supply (AS) for the imaginary country of Cotopaxi in the year 2027.
Suppose the natural level of output in this economy is $6 trillion.
On the following graph, use the green line (triangle symbol) to plot the long-run aggregate supply (LRAS) curve for this economy.
Economists forecast that if the government takes no action and the economy continues to grow at the current rate, aggregate demand in 2028 will be given by the curve labeled ADAADA, resulting in the outcome given by point A. If, however, the government pursues an expansionary policy, aggregate demand in 2028 will be given by the curve labeled ADBADB, resulting in the outcome given by point B.
The following table presents projections for the unemployment rates that would occur at point A and point B. Consider the potential rate of inflation between 2027 and 2028, depending on whether the economy moves from the initial price level of 102 to the…
The graphs illustrate an initial equilibrium for the economy. Suppose that the government increases spending.
Use the graphs to show the new positions of aggregate demand (AD), short‑run aggregate supply (SRAS), and long‑run aggregate supply (LRAS) in both the short run and the long run, as well as the short‑run and long‑run equilibriums resulting from this change. Then, indicate what happens to the price level and real GDP (or aggregate output) in the short run and in the long run. Adjust the graph.
explain the second image as well and which is right.
Refer to the data in the table below. Suppose that the present equilibrium price level and level of real GDP are 100
and $255, and that data set B represents the relevant aggregate supply schedule for the economy.

a. What must be the current amount of real output demanded at the 100 price level?
$
b. If the amount of output demanded declines by $25 at the 100 price level shown in B, what would be the new
equilibrium real GDP?
In business cycle terminology, economists would likely call this change in real GDP (Click to select) ✓
