business pessimism about future conditions
the multiplier is defined as
change in GDP / initial change in spending.
The multiplier is useful in determining the
change in GDP resulting from a change in spending
A specific reduction in government spending will dampen demand-pull inflation by a greater amount the

business inventories will fall
The expenditure multiplier concept of the aggregate expenditures model
magnifies the shifts of the aggregate demand curve.

aggregate demand increases because net exports
An increase in net exports will shift the
aggregate expenditures curve upward and the aggregate demand curve rightward.
Which event would most likely decrease an economy's export?
an appreciation of the nation's currency relative to foreign currencies
In deriving the aggregate demand curve from the aggregate expenditures model, we note that
an increase (decrease) in the price level shifts the aggregate expenditures schedule downward (upward).
Which of the following events would most likely reduce aggregate demand?
an increase in real interest rates
An MPC value of less than 1.0 indicates that as income increase,
consumption also increases, though not as much as income
Actual investment is $28 billion and saving is $15 billion at the $166 billion level of output in a private closed economy. At this level,
consumption will be $151 billion
Refer to the diagram, in which Qf is the full-employment output. The shift of the aggregate demand curve from AD3 to AD2 is consistent with
contractionary fiscal policy
The intent of contractionary fiscal policy is to
decrease aggregate demand
The set of fiscal policies that would be most contractionary would be a(n)
decrease in government spending and an increase in taxes.
To close an inflationary expenditure gap of $20 billion in an economy with a marginal propensity to consume of 0.8, it would be necessary to
decrease the aggregate expenditures schedule by $20 billion
If the MPC in an economy is 0.8, government could shift the aggregate demand curve rightward by $100 billion by
decreasing taxes by $25 billion
As the consumption and saving schedules relate to real GDP, an increase in taxes will shift
downward both the consumption and saving schedules.
Other things being equal, the effect of a downward shift of the economy's net export schedule on equilibrium GDP will be similar to a(n)
downward shift in the consumption schedule
If a government wants to pursue an expansionary fiscal policy, then a tax cut of a certain size will be more expansionary when the
economy's MPS is small.
A given reduction in government spending will dampen demand-pull inflation by a greater amount when the
economy's aggregate supply curve is steep
The immediate determinants of investment spending are the
expected rate of return on capital goods and the real interest rate.
When the Federal government uses taxation and spending actions to stimulate the economy, it is conducting
fiscal policy
C = 40 + 0.8 Y Ig = 40 X = 20 M = 30 The equations give info for a private open economy. The letters Y, C, Ig, X, and M stand for GDP, consumption, gross investment, exports, and imports, respectively. Figures are in billions of dollars. International trade in this case
has a contractionary effect on GDP
If the price level decrease from 200 to 100, the real output demanded will
increase by $200 billion
Other things equal, if $100 billion of government purchases (G) is added to private spending (C + Ig + Xn), GDP will
increase by more than $100 billion.
Other things equal, an increase in an economy's exports will
increase its domestic aggregate expenditures and therefore increase its equilibrium GDP.
In the aggregate expenditures model, an increase in government spending may
increase output and employment
In the aggregate expenditure model, a reduction in taxes may
increase saving
Refer to the graph. If the price level is initially at P1, then the economy will adjust by

increasing taxes by $20 billion
Discretionary fiscal policy refers to
intentional changes in taxes and government expenditures made by Congress to stabilize the economy
Discretionary fiscal policy is so named because it
involves specific changes in taxes and government spending undertaken expressly for stabilization at the option of Congress
The economy's long-run aggregate supply curve
is vertical
The effect of contractionary fiscal policy is shown as a
leftward shift in the economy's aggregate demand curve
Graphically, cost-push inflation is shown as a
leftward shift of the AS curve.
In a recessionary expenditure gap, the equilibrium level of real GDP is
less than full-employment GDP.
A firm invests in a new machine that costs $5,000 a year but which is expected to produce an increase in total revenue of $5,200 a year. The current real rate of interest is 7 percent. The firm should
not undertake the investment because the expected rate of return of 4 percent is less than the real rate of interest

reciprocal of the slope of the saving schedule.

shift the aggregate supply curve to the right
If Trent's MPC is 0.80, this means that he will
spend eight-tenths of any increase in his disposable income
An economy is employing 2 units of capital, 5 units of raw materials, and 8 units of labor to produce its total output of 640 units. Each unit of capital costs $10; each unit of raw materials, $4; and each unit of labor, $3. If the per-unit price of raw materials rises from $4 to $8 and all else remains constant, the aggregate
supply curve would shift to the left
Consumption is $141 billion, planned investment is $15 billion, and saving is $15 billion in a private, closed economy. At this level,
the economy is in equilibrium
The aggregate expenditures model and the aggregate demand curve can be reconciled because, other things equal, in the aggregate expenditures model,
the level of aggregate expenditures and therefore the level of real GDP vary inversely with the price level.
Deflation refers to a situation where
the price level falls; it could be caused by a shift of AD to the left
If aggregate demand decreases, and, as a result, real output and employment decline but the price level remains unchanged, it is most likely that
the price level is inflexible downward and a recession has occurred.
when government spending is increased, the amount of the increase in aggregate demand primarily depends on:
the size of the multiplier
Which is not a reason why the stimulus package that the government implemented during the Great Recession of 2007-09 did not have as strong an impact on GDP and unemployment as expected?
the stimulus package cause prices to fall in many sectors
