The basic aggregate demand and aggregate supply curve model helps explain
________ fluctuations in real GDP and the price level.
Short term
Which of the following is one explanation as to why the aggregate demand curve
slopes downward?
Decreases in the price level raise real wealth and increase consumption spending.
How do lower taxes affect aggregate demand?
They increase disposable income, consumption, and aggregate demand.
If aggregate demand just decreased, which of the following may have caused the
decrease?
a decrease in exports

growth rates. This will
shift the aggregate demand curve to the right.
When the price level in the United States falls relative to the price level of other
countries, ________ will fall, ________ will rise, and ________ will rise.
imports; exports; net exports

underestimated the price level would be represented by a movement from
SRAS2 to SRAS1.
On the long-run aggregate supply curve,
a decrease in the price level has no effect on the aggregate quantity of GDP supplied.
If the economy receives an influx of new workers from immigration,

,the long-run aggregate supply curve will shift to the right.
Suppose a developing country experiences a reduction in machinery and capital
equipment as foreign entrepreneurs decrease the amount of investment in the
economy. As a result,
the long-run aggregate supply curve will shift to the left.
Changes in the price level
do not affect the level of aggregate supply in the long run.
Suppose the economy is at point A. If investment spending increases in the
economy, where will the eventual long-run equilibrium be?
c
The automatic mechanism ________ the price level in the case of ________ and
________ the price level in the case of ________.
lowers; recession; raises; expansion
Stagflation occurs when
inflation rises and GDP falls.
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
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.
Which of the following correctly describes the automatic mechanism through
which the economy adjusts to long-run equilibrium?
the rightward shift of the short-run aggregate supply curve that occurs after a recession
Given the economy is at point A in year 1, what is the difference between the
actual growth rate in GDP in year 2 and the potential growth rate in GDP in year
2?
2.7%
Which of the following could explain why there is an increase in potential GDP
but the equilibrium level of GDP falls?
AD did not shift and SRAS shifted to the left.
Gretchen expects the price level to rise from 104 this year to 108 next year, and
she is able to incorporate these expectations into her wage contract. If the price
level rises to 106 next year instead of 108, which of the following will occur?
Gretchen's real wage will rise.
If changes in inflation are higher than expected,
the short-run Phillips curve will be negatively sloped.
Which of the following best explains the negative slope of the short-run Phillips
curve?
Weak growth in aggregate demand keeps the economy below potential GDP, so
unemployment rises but inflation falls.
The long-run aggregate supply curve is ________, while the long-run Phillips
curve is ________.
vertical; also vertical
The natural rate of unemployment equals
structural plus frictional unemployment.

,If aggregate demand just increased, which of the following may have caused the
increase?

wealth?
a credit card balance
According to the "wealth effect," when the ________ falls, the ________ rises.
price level; the real value of household wealth

growth rate of foreign GDP would be represented by a movement from
AD1 to AD2.
Higher personal income taxes
decrease aggregate demand.

overestimated the price level would be represented by a movement from
SRAS1 to SRAS2.

changes in the price level.

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.
If workers leave a country to seek out better opportunities in another country,
then this will
shift the short-run aggregate supply curve of the original country to the left.

curve look like?
It is a vertical line at $600 billion of GDP.
