CH3-1. Which of the following is an exogenous variable in our model of the goods market in Chapter 3?

• a. consumption (C)
• b. saving (S)
• c. disposable income (YD)
• d. government spending (G)
• e. none of the above.

CH3-2. Which of the following is an endogenous variable in our model of the goods market in Chapter 3?

• a. consumption (C)
• b. disposable income (YD)
• c. saving (S)
• d. total income (Y)
• e. all of the above.

CH3-3. Suppose the consumption equation is represented by the following: C = 250 + 0.75*YD. The multiplier in this economy is

• a. 0.25
• b. 0.75
• c. 1
• d. 4
• e. 5

CH3-4. C = 1000 + 0.75*YD 、 I = 500 、 G = 2000 、 T = 1000. The equilibrium level of GDP for the above economy equals:

• a. 2500.
• b. 4500.
• c. 10000.
• d. 11000.
• e. none of the above.

CH3-5. C = 1000 + 0.75*YD 、 I = 500 、 G = 2000 、 T = 1000. The multiplier for the above economy equals:

• a. 2.
• b. 3.
• c. 4.
• d. 5.
• e. none of the above.

CH3-6. C = 1000 + 0.75*YD 、 I = 500 、 G = 2000 、 T = 1000. Suppose government spending increases by 100 for the above economy. Given the above information, we know that equilibrium output will increase by:

• a. 200.
• b. 400.
• c. 800.
• d. 1000.
• e. none of the above .

CH3-7. C = 1000 + 0.75*YD 、 I = 500 、 G = 2000 、 T = 1000. The equation for private (or, equivalently, household) saving in this model is S =:

• a. -1000 + 0.25YD
• b. -1000 + 0.75YD
• c. -1000 - 0.25YD
• d. 3500 + 0.25Y
• e. 3500 + 0.75Y

CH3-8. Which of the following events will cause a reduction in equilibrium output?

• a. an increase in the marginal propensity to save.
• b. an increase in taxes.
• c. a reduction in the marginal propensity to consume.
• d. all of the above.
• e. none of the above.

CH3-9. Based on our understanding of the model presented in Chapter 3, we know that a reduction in c1 (where C = c0 + c1YD) will cause:

• a. the ZZ line to become steeper and a given change in autonomous consumption (c0) to have a smaller effect on output
• b. the ZZ line to become steeper and a given change in autonomous consumption (c0) to have a larger effect on output
• c. the ZZ line to become flatter and a given change in autonomous consumption(c0) to have a smaller effect on output
• d. the ZZ line to become flatter and a given change in autonomous consumption(c0) to have a larger effect on output.

CH4-1. Which of the following will cause an increase in the amount of money that one wishes to hold?

• a. an increase in the interest rate increase.
• b. a reduction in the interest rate increase.
• c. a reduction in income.
• d. none of the above
