positive, zero, or negative?
7. If nominal GDP increased 15% and the price index increased 10%, would the change in real output be

5. How do economists define the “labor force?”
6. How do economists define the “unemployment rate?”

Chapter 28
1. Identify the determinants, other than disposable income, that affect levels of consumer spending and
the effect that each determinant has on consumer spending.
2. Given that the marginal propensity to consume (MPC) is 0.8, calculate each of the following:
a. the marginal propensity to save (MPS)
b. the investment spending multiplier
c. the government spending multiplier
d. the tax multiplier
e. the increase in GDP that would be created by a $100 billion increase in investment spending
f. the increase in GDP that would be created by a $50 billion reduction in taxes
g. the increase in GDP that would be created by a $200 billion increase in government spending
3. If the marginal propensity to consume is 0.75 and disposable income increases by $1 billion, what will
the change in consumption spending be?
4.
a. If the marginal propensity to consume is 0.8, how much would a $1 billion tax increase reduce
consumption spending?
b. If the government then spent all of that $1 billion tax increase, what would be the resulting
change in total spending?
c. Given your answers to b and c above, if the government increases taxes and government
spending by the same amount, will the overall effect on GDP be positive, zero, or negative?
