1) Scenario 15-3
A monopoly firm maximizes its profit by producing Q = 500 units of output. At that
level of output, its marginal revenue is $30, its average revenue is $60, and its average
total cost is $34.
At Q = 500, the firm’s marginal cost is
a. less than $30.
b. $30.
c.$34.
d.greater than $34.
2) Miguel is a 20 year old college student who works part-time and earns an annual
income of $12,000. To smooth out his life cycle changes in income, Miguel can
a.save his earnings to use when he is middle-aged.
b.lend money to a friend to purchase a new car.
c.borrow money to pay for college, which he will later repay when his income rises.
d.attempt to pay for college from his current earnings.
3) Scenario 20-3
Suppose that a society is made up of five families whose incomes are as follows:
$120,000; $90,000; $30,000; $30,000; and $18,000.
The federal government is considering two potential income tax plans:
Plan A is a negative income tax plan where the taxes owed equal 1/3 of income minus
$20,000.
Plan B is a two-tiered plan where families earning less than $35,000 pay no income tax
and families earning more than $35,000 pay 10% of their income in taxes. The income
tax revenue collected from those families earning over
$35,000 is then redistributed equally to those families earning less than $35,000.
Refer to Scenario 20-3. Assuming that utility is directly proportional to the cash value
of after-tax income, which government policy would an advocate of liberalism prefer?
a.Plan A
b.Plan B
c.either Plan A or Plan B
d.neither Plan A nor Plan B because any plan that forcibly redistributes income is
against the philosophy
