Document Summary

Why wages change: output gaps, y > y* - excess demand for labour, y < y* - excess supply of labour, expected inflation, some firms raise wages in advance of inflation. Change in money wages = output gap effect + expectational effect. From wages to prices: overall effect on nominal wages determines how the as curve shifts - has an impact on the price level. Actual inflation = output-gap inflation + expected inflation + supply shock inflation: the last term captures any shifts in the as curve caused by things other than wage changes. Demand shocks: demand inflation results from a rightward shift of the ad curve, a demand shock that is not validated produces only temporary inflation. With monetary validation: the ad curve shifts further to the right, keeping open the inflationary gap, continued validation turns transitory inflation into sustained accelerating inflation.

Here is the question and the answers. But I need an explanation of WHY the answer is what it is. Any answers that don't answer why for each one will only get 1 star.

What effects would each of the following have on aggregate demand or aggregate supply? In each case use a diagram to show the expected effects on the equilibrium price level and level of real output. Assume that all other things remain constant.

a. A widespread fear of depression on the part of consumers.

b. A $2 increase in the excise tax on a pack of cigarettes.

c. A reduction in interest rates at each price level.

d. A major increase in Federal spending for health care.

e. The expectation of rapid inflation.

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

g. A 10 percent 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. Depreciation in the international value of the dollar.

ANSWERS

(a) AD curve left, output down and price level down (assuming no ratchet effect).

(b) AS curve left, output down and price level up.

(d) AD curve right, output and price level up (any real improvements in health care resulting from the spending would eventually increase productivity and shift AS right).

(e) AD curve right, output and price level up.

(f) AS curve right, output up and price level down.

(g) AD curve right, output and price level up.

(h) AS curve right, output up and price level down.

(i) AS curve left, output down and price level up.

(j) AD curve right (increased net exports); AS curve left (higher input prices)
