Economics Final

The aggregate expenditure model focuses on the relationship between ________ and ________ in the short run, assuming ________ is constant.

total spending; real GDP; the price level

The key idea of the aggregate expenditure model is that in any particular year, the level of GDP is determined mainly by

the level of aggregate expenditure.

A decrease in consumer confidence can put your job at risk if

aggregate expenditures fall.

Household spending on goods and services is known as

consumption spending.

The aggregate expenditure model focuses on the ________ relationship between real spending and ________.

short-run; real GDP

Which is the largest component of aggregate expenditure?

consumption expenditures

A decrease in Social Security payments will

decrease consumption spending.

The marginal propensity to consume is defined as

the change in consumption divided by the change in disposable income.

If firms are more optimistic that future profits will rise and remain strong for the next few years, then

investment spending will rise.

Refer to Figure 11-1. At point L in the figure above, which of the following is true?

Actual inventories are greater than planned inventories.

Which of the following leads to a decrease real GDP?

an increase in interest rates

Refer to Figure 11-3. Suppose that investment spending increases by $10 million, shifting up the aggregate expenditure line and GDP increases from GDP1 to GDP2. If the MPC is 0.9, then what is the change in GDP?

$100 million

Autonomous expenditure is a type of expenditure that does not depend on

GDP.

If an increase in autonomous consumption spending of $10 million results in a $50 million increase in equilibrium real GDP, then

the MPC is 0.8.

A general formula for the multiplier is

1 / (1 - MPC)

Refer to Figure 11-2. If the U.S. economy is currently at point K, which of the following could cause it to move to point N?

The aggregate demand curve illustrates the relationship between ________ and the ________, holding constant all other factors that affect aggregate expenditure.

the price level; quantity of planned aggregate expenditure

If firms reduce the rate at which inventories are rising,

firms are less likely to reduce production when sales fall.

A decrease in aggregate expenditure has what result on equilibrium GDP?

Equilibrium GDP falls.

Given the equations for C, I, G, and NX below, what is the equilibrium level of GDP?
C = 1,000 + 0.8Y
I = 1,500
G=1,250
NX = 100

$19,250

Equations for C, I, G, and NX are given below. If the equilibrium level of GDP is $21,500, what is the marginal propensity to consume?
C = 1,500 + (MPC)Y
I = 1,000
G = 2,000
NX = -200

0.8

U.S. net export spending rises when

the growth rate of U.S. GDP is slower than the growth rate of GDP in other countries.

business cash flow increases.

Investment spending ________ during a recession, and ________ during an expansion.

declines; increases

Which of the following is true?

When the price level in the United States rises relative to the price level of other countries, ________ will rise, ________ will fall, and ________ will fall.

imports; exports; net exports

The international trade effect states that

an increase in the price level will lower net exports.

Inflation will

...

If the U.S. dollar increases in value relative to other currencies, how does this affect the aggregate demand curve?

This will shift the aggregate demand curve to the left.

The level of long-run aggregate supply is not affected by

changes in the price level.

The level of real GDP in the long run is called

potential GDP.

The long-run aggregate supply curve

is vertical.

Potential GDP is also referred to as

full-employment GDP.

What is potential GDP?

the level of real GDP in the long run

On the long-run aggregate supply curve,

an increase in the price level has no effect on the aggregate quantity of GDP supplied.

Changes in the price level

do not affect the level of aggregate supply in the long run.

The invention of the cotton gin ushered in the Industrial Revolution and began a long period of technological innovation. What did this technological change do the short-run supply curve?

It shifted the short-run aggregate supply curve to the right.

Hurricane Katrina destroyed oil and natural gas refining capacity in the Gulf of Mexico. This subsequently drove up natural gas, gasoline, and heating oil prices. As a result, this should

...

Which of the following would cause the short-run aggregate supply curve to shift to the right?

a technological advance

Long-run macroeconomic equilibrium occurs when

aggregate demand equals short-run aggregate supply and they intersect at a point on the long-run supply curve.

A decrease in aggregate demand results in a(n) ________ in the ________.

recession; short run

Short-run macroeconomic equilibrium occurs when

...

An increase in aggregate demand in the economy will have what effect on macroeconomic equilibrium in the long run?

The price level will rise, and the level of GDP will be unaffected.

Refer to Figure 12-1. Which of the points in the above graph are possible long-run equilibria?

A and C

Refer to Figure 12-1. Which of the points in the above graph are possible short-run equilibria but not long-run equilibria? Assume that Y1 represents potential GDP.

B and D

Refer to Figure 12-1. Suppose the economy is at point C. If government spending decreases in the economy, where will the eventual long-run equilibrium be?

A

The long-run adjustment to a negative supply shock results in

the short-run aggregate supply curve shifting to the right.

Which of the following is not an assumption made by the dynamic model of aggregate demand and aggregate supply?

Aggregate demand and potential real GDP decrease continuously.

Refer to Figure 12-2. In the figure above, LRAS1 and SRAS1 denote LRAS and SRAS in year 1, while LRAS2 and SRAS2 denote LRAS and SRAS in year 2. Given the economy is at point A in year 1, what is the growth rate in potential GDP in year 2?

10%

Refer to Figure 12-2. Given the economy is at point A in year 1, What will happen to the unemployment rate in year 2?

It will rise.

In the dynamic aggregated demand and aggregate supply model, inflation occurs if

AD shifts faster than AS

Money is

The primary tool the Federal Reserve uses to increase the money supply is

Which policy tool allows the Federal Reserve the greatest control over monetary policy?

Lowering the discount rate will

increase reserves, encourage banks to make more loans, and increase the money supply.

If the Fed buys U.S. Treasury securities, then this
