The short-run economic outcome resulting from the increase in production costs is known as——-
Suppose now that the government immediately pursues an accommodative policy by increasing government purchases in response to the short-run impact of the higher oil prices.
In the long run, given that the government pursues accommodative policy, the output level in the economy will equal ——- level will equal———
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.
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 task I am struggling with: The economy is in short-run macroeconomic equilibrium at point E1 in the accompanying diagram (see the picture). Based on the diagram, answer the following questions. a) Is the economy facing an inflationary or recessionary gap? b) What policies can the government implement that might bring the economy back to long-run macroeconomic equilibrium? Illustrate with a diagram. c) If the government did not intervene to close this gap, would the economy return to long-run macroeconomic equilibrium? Explain and illustrate with a diagram.Thank you very much for your help.arrow_forwardThe following graph shows a hypothetical economy in long-run equilibrium at an expected price level of 120 and a natural output level of $600 billion.
