1) If a worker respond to an increase in the opportunity cost of leisure by taking more
leisure, then her labor supply curve is
a.upward sloping.
b.backward sloping.

2) Scenario 18-7
Suppose the following events occur in the market for university economics professors.
Event 1: A recession in the U.S. economy lowers the opportunity cost of going to
graduate school in economics to become a university economics professor.
Event 2: An increasing number of students in U.S. primary and secondary schools
increases the number of students entering college, increasing the output price of
university economics professors' services.
Refer to Scenario 18-7. As a result of these two events, holding all else constant, the
equilibrium quantity of university economics professors will
a.increase.
b.decrease.
c.not change.
d.It is not possible to determine what will happen to the equilibrium quantity.
3) Figure 7-27
Refer to Figure 7-27. If the government mandated a price increase from P1 to a higher
price, then
a.total surplus would decrease.
b.consumer surplus would increase.
c.total surplus would increase, since producer surplus would increase.
d.total surplus would remain unchanged.
4) Gary and Diane must prepare a presentation for their marketing class. As part of their
presentation, they must do a series of calculations and prepare 50 PowerPoint slides. It
would take Gary 10 hours to do the required calculation and 10 hours to prepare the
slides. It would take Diane 12 hours to do the calculations and 20 hours to prepare the
slides.
a.How much time would it take the two to complete the project if they divide the
calculations equally and the slides equally?
b.How much time would it take the two to complete the project if they use comparative
advantage and specialize in calculating or preparing slides?
c.If Diane and Gary have the same opportunity cost of $5 per hour, is there a better
solution than for each to specialize in calculating or preparing slides?

d.demand is inelastic and supply is elastic.
7) Diminishing marginal product affects the shape of the production function in what
way?

d.The production function is horizontal beyond a certain quantity of input.
8) When strategic interactions are important to pricing and production decisions, a
typical firm will
a.set the price of its product equal to marginal cost.
b.consider how competing firms might respond to its actions.
c.generally operate as if it is a monopolist.

b.An economy can produce at any point inside or outside a production possibilities
frontier.
c.An economy can produce at any point on or inside the production possibilities
frontier, but not outside the frontier.
