Document Summary

Relationship between price level and quantity of real gdp supplied, all other determinants held constant. As the price level rises(falls) firms are willing to produce more(less) Unit costs of some inputs are fixed for a period of time. Higher selling prices for output makes production more attractive. Nominal wage rate money wage rate. Higher wage rates cause production costs to increase and profits to fall. Same effect on as as with wage rates. What happened to as in fall 2014: it shifted right as energy prices fell. So improvements in technology shift as curve outward (right) Aggregate quantity demanded(aqd) = aggregate quantity supplied(aqs) Increases in ad push up the price level. Inflationary gap: amount by which equilibrium real gdp > full employment gdp. Recessionary gap: amount by which equilibrium real gdp < full employment gdp. Price level falls and real gdp increases. This process could take a long time. Why nominal wages and prices won"t fall easily.

Related Questions

1) If actual (equilibrium ) real GDP is less than the full-employment, or natural, level of real GDP, then wages and other input prices are expected to:

a. fall and SRAS to shift to the left until long-run equilibrium is achieved.

b. fall and SRAS to shift to the right until long-run equilibrium is achieved.

c. rise and SRAS to shift to the left until long-run equilibrium is achieved.

d. rise and SRAS to shift to the right until long-run equilibrium is achieved.

2) In a self-regulating economy, inflationary gaps are automatically eliminated in the long run by:

a. decreases in wage rates that cause short-run aggregate supply to shift rightward.

b. decreases in wage rates that cause short-run aggregate supply to shift leftward.

c. increases in wage rates that cause short-run aggregate supply to shift rightward.

d. increases in wage rates that cause short-run aggregate supply to shift leftward.

3) Assume the economy is initially in equilibrium at the full-employment level of real GDP. If businesses and consumers become pessimistic regarding future economic conditions, ceteris paribus, the aggregate demand curve will shift to the ________, causing the level of output to ______.

a. left; fall

b. right; fall

c. left; rise

d. right; rise

4) Economists that advocate a macroeconomic policy of laissez-faire:

a. believe the economy is self-regulating only if the government intervenes to move the economy to equilibrium at natural real GDP.

b. believe the economy is self-regulating and will automatically move to equilibrium at natural real GDP in the long run.

c. also advocate central planning and government control of resources.

d. also advocate active government intervention in the economy.

5) Which of the following summarizes the process for closing a recessionary gap if the economy is self-regulating?

a. Labor shortages put upward pressure on wages, which leads to higher costs of production and a decrease in short-run aggregate supply.

b. Labor shortages put downward pressure on wages, which leads to increases in employment and spending and an increase in aggregate demand.

c. Unemployed resources put upward pressure on the price level, which leads to higher wages, increases in spending, and increases in aggregate demand.

d. Unemployed resources put downward pressure on the price level, which leads to lower costs of production and an increase in short-run aggregate supply.

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)

1. Which of the following shifts aggregate demand to the right?
a. Congress reduces purchases of new weapons systems.
b. US exports increase.
c. The price level falls
d. New developments in IT increase the productivity of most manufacturing industries in the US.

2. Suppose the EPA introduces new smog regulation that makes it costlier to produce cars. As a result, aggregate supply falls (primary effect) and firms cut back on production. With less output in the economy available for consumers, consumers bid up the prices of available output. With higher prices, firms choose to produce more (secondary effect).
Which of the following best explains what the net effect on GDP?
a. The two effects should essentially cancel out, with little to no effect on GDP, but the price level clearly rises.
b. It is impossible to say what happens to GDP without being able to compare the magnitudes of the two effects.
c. Real GDP rises as the secondary effect dominates the primary effect.
d. Real GDP falls since the primary effect dominates the secondary effect.

3. A Keynesian economist who observes an output gap would conclude that
a. aggregate demand should be shifted to the right.
b. a policy of deregulation would be better than demand management policy
c. aggregate supply should be shifted to the right
d. All proposed answer options are correct

4. Monetarists believe
a. the Aggregate Supply curve is upward-sloping (but not vertical) over all time frames.
