Additional Practice Questions-
1. Holding everything else constant, in the simple Keynesian Model presented in class, when aggregate expenditure is greater than production, this reduces the level of inventories and in the short-run results in an increase in the aggregate price level.
a. True
b. False
2. Which of the following statements best describes the differences between the Classical and Keynesian models presented in class?
a. When the economy is in the midst of an economic recession, the Keynesian economist typically will advocate governmental intervention while the Classical economist will advocate patience.
b. According to the Classical Model, economic fluctuations are due to a disequilibrium in the labor market; in the simple Keynesian Model, when aggregate expenditure is greater than actual production, prices rise to eliminate this disequilibrium.
3. Deliberate actions by policy makers that cause fiscal policy to be expansionary when the economy contracts are called automatic stabilizers.
a. True
b. False
4. Consider an economy using the Keynesian model as presented in class. The value of the autonomous expenditure multiplier [1/(1-b)] in this economy is 2. If government spending increases by $50 while taxes simultaneously increase by $50, what will happen to the equilibrium level of GDP?
a. It will not effectively change the level of output since the increase in government spending which stimulates spending is exactly offset by the increase in taxes which contracts spending.
b. It will cause the equilibrium level of GDP to increase by less than $50 because of the multiplier effect.
c. It will cause the equilibrium level of GDP to increase by more than $50 because of the multiplier effect.
d. It will cause the equilibrium level of GDP to increase by exactly $50 due to the multiplier effect.
Use the Loanable Funds Model to answer the nexttwo questions:
Y = C + SP + T - TR
SG = T - TR - G
NS = SP + SG
NS = Y - C - G
KI = M - X
Y = C + I + G + (X - M)
In equilibrium, leakages = injections
Furthermore, suppose the government runs a balanced budget (that is, G - T + TR = 0) and collects $300 in tax revenue. Firms spend $55 on new capital and capital inflow equals $15. Income equals $450 and $220 of that income is spent on consumption. Furthermore, leakages equal injections in this economy.
5. What is the level of private saving in this economy?
a. $55 since private saving must equal investment in order for the loanable funds market to be in equilibrium.
b. $70 since businesses are spending $55 of their own money plus $15 provided via the foreign sector (i.e., the capital inflow).
c. $40 since businesses are demanding $55 worth of loanable funds and the foreign sector is supplying only $15 worth of loanable funds.
d. $25 since the total demand for loanable funds is $40 and there are $15 of loanable funds being supplied through the capital inflow.
6. What is the level of government transfers in this economy?
a. $0
b. $90
c. $110
d. $125
7. According to the Loanable Funds Model, which of the following will most likely contribute to long-run growth?
a. An increase in payments to the unemployed.
b. Increased restrictions on immigration.
c. Improved birth control methods.

8. Answer this question according to the Classical Model. The US runs a trade deficit with China. Holding everything else constant, if the US narrows this gap by increasing exports, what will happen to the level of investment in the United States?
a. Investment in the U.S. will increase relative to its initial level.
b. Investment in the U.S. will decrease relative to its initial level.
c. Investment in the U.S. could either increase or decrease relative to its initial level.
d. There will be no effect on investment in the U.S.
9. The full employment level of output in an economy refers to the level of output produced when:
a. Everyone above age 16 is working.
b. Everyone above age 16 who wants a job is working.
c. There is no unemployment due to the business cycle.
d. There is no cyclical or structural unemployment.

Consider a closed economy whose price levels in 2004 and 2005 are the same. The GDPs in 2004 and 2005 are $4,000 and $5,000, respectively. Household consumption was $3,000 and private saving was $500 in 2004. In 2005, the government deficit increased by $500. Private saving was $1,500 in 2005. Analyze this economy using the Classical model given below:
