1) What effects would each of the following have on aggregate demand or aggregate supply, other things equal? In each case, use a diagram to show the expected effects on the equilibrium price level and the level of real output, assuming that the price level is flexible both upward and downward. (LO3)

a.A widespread fear by consumers of an impending economic depression.

b.A new national tax on producers based on the value added between the costs of the inputs and the revenue received from their output.

c.A reduction in interest rates.

d. A major increase in spending for health care by the federal government.

e.The general expectation of coming rapid inflation.

f. The complete disintegration of OPEC, causing oil prices to fall by one-half.

g. A 10 percent across-the-board reduction in personal income tax rates.

h. A sizable increase in labor productivity (with no change in nominal wages).

i. A 12 percent increase in nominal wages (with no change in productivity).

j. An increase in exports that exceeds an increase in imports (not due to tariffs)

3. Suppose that the aggregate demand and aggregate supply schedules for a hypothetical economy are as shown in the following table. (LO3) Amount of Real GDP Demanded, Price Level (Price Amount of Real GDP Supplied, Billions Index) Billions 3100 300 3450 200 250 400 300 200 300 400 150 200 500 100 100 a. lUse the preceding data to graph the aggregate demand and aggregate supply curves. What is the equilibrium price level and the equilibrium level of real output in this hypothetical economy? Is the equilibrium real output also necessarily the full-employment real output? b. If the price level in this economy is 150, will quantity demanded equal, exceed, or fall short of quantity supplied? By what amount? If the price level is 250, will quantity demanded equal, exceed, or fall short of quantity supplied? By what amount? c. Suppose that buyers desire to purchase 3200 billion of extra real output at each price level. Sketch in the new aggregate demand curve as AD,. What is the new equilibrium price level and level of real output
