Other things equal, what effects would each of the following have on aggregate demand or aggregate supply? In each case use a diagram to show the expectedeffects on the equilibrium price level and the level ofreal output.a. A reduction in the economy’s real interest rate.b. A major increase in federal spending for healthcare (with no increase in taxes).c. The complete disintegration of OPEC, causing oilprices to fall by one-half.
d. A 10 percent reduction in personal income taxrates (with no change in government spending).e. A sizable increase in labor productivity (with nochange in nominal wages).f. A 12 percent increase in nominal wages (with nochange in productivity).g. A sizable depreciation in the international value ofthe dollar.
I don't quite understand what is asking of the change that will occur in the long run
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.

- What are three factors that help explain the slope of the aggregate demand curve? What is the most important factor? Why?arrow_forwardSuppose the economy is in a long-run equilibrium, as shown in the following graph. Now suppose that firms become pessimistic about future business conditions and decide to cut back on investment spending, resulting in a fall in aggregate demand.
