Practice Exam 2 Questions Macro
If real GDP is $6,460 billion, the population is 184.6 million people, and total labor hours are 170 billion, labor productivity is
$38.00 an hour.
the tax multiplier is 5 and, as a result of a change in taxes, equilibrium real GDP changes by $200 billion. What was the initial change in taxes?
$40 billion
f an increase of $10 billion of government spending results in an increase in equilibrium real GDP of $40 billion, the multiplier equals
$40 billion ÷ $10 billion = 4
n a small nation to the South, labor productivity last year was $25 per hour and total labor hours were 300 hours. Hence, real GDP was
$7,500

-Equal to potential GDP -produced when the labor market is in equilibrium. -when there is full employment.
New growth theory asserts that

A minimum wage rate that is set ________ the equilibrium real wage rate creates a ________ of labor
above; surplus
Job rationing occurs when the real wage is ________ the equilibrium level and there is a ________ of labor.
above; surplus
The figure above shows the market for fast food restaurant employees in a college town. The local Taco Bell pays its workers $9 an hour. This wage rate is
an efficiency wage aimed at reducing employee turnover.
Moving along the aggregate demand curve, a decrease in the quantity of real GDP demanded is a result of
an increase in the price level.
Which of the following is true
at full employment, aggregate supply is equal to potential GDP
If the minimum wage is
at the equilibrium wage in the labor market, it will create neither a shortage nor a surplus of labor
In an expansion, federal tax receipts increase proportionally more than real GDP without the need for any government policy. This increase is an example of
automatic fiscal policy.
In the labor market, the income tax creates a tax wedge which raises the ________ wage rate, reduces the ________ wage rate, and ________ employment.
before-tax; after-tax; decreases
A change in the full-employment quantity of labor shifts
both the aggregate supply curve and the potential GDP line
in 2001, U.S. real GDP decreased by 3 percent and the population grew by 1 percent. Thus, real GDP per person
decreased 4 percent
In Brazil last year, the growth rate of real GDP was 3.5 percent and the population grew from 1,000 million people to 1,100 million. Real GDP per person
decreased by 6.5 percent.
If capital per hour of labor decreases, real GDP per hour of labor
decreases for a given level of technology
The government collects tax revenues of $100 million and has $105 million in outlays. The budget balance is a
deficit of $5 million.
Automatic stabilizers decrease the impact of a recession on the level of economic activity because they
imply that disposable income does not change by as much as real GDP.
A rise in the expected future inflation rate
increases aggregate demand.
The supply-side effects show that a tax cut on labor income ________ the supply of labor and ________ employment.
increases; increases
The government could increase aggregate demand by $1 trillion by
increasing its purchases by less than $1 trillion.
A recessionary gap means that short-run macroeconomic equilibrium GDP
is less than full-employment GDP.
if the stock of physical capital (that is machinery, equipment, etc.) and human capital remain the same and the population increases, then
labor productivity will decrease
Classical growth theory predicts that increases in real GDP per person will
not last because higher income leads to a population explosion
One reason that the aggregate demand curve has a negative slope is because
people buy more foreign goods when the domestic price level rises
if the economy is in the expansion phase of a business cycle and investment increases, when the multiplier effect kicks in, the expansion
picks up speed.
Population growth directly brings growth in ____ because aggregate hours increase
real GDP
The productivity curve is a relationship between ________ and _______
real GDP per hour of labor; capital per hour of labor
The real wage rate is $35 an hour. At this wage rate there are 100 billion labor hours supplied and 200 billion labor hours demanded. There is a
shortage of 100 billion hours of labor.

the federal budget is in surplus.
If workers are successful in obtaining 6 weeks of paid vacation where 2 weeks used to be the norm, then most likely
the price level will increase
