a.the value to Barb of the option she would have chosen had Option B not been
available.
b.the value to Barb of Options A, C and D combined.
c.the average of the values to Barb of Options A, C, and D. d. $100.

4) Juanita and Shantala run a business that programs and tests cellular phones. Assume
that Juanita and Shantala can switch between programming and testing cellular phones
at a constant rate. The following table applies.
Which of the following points would be on Shantala's production possibilities frontier,
based on a 40-hour week?
a.(120 cellular phones programmed, 250 cellular phones tested)
b.(180 cellular phones programmed, 150 cellular phones tested)
c.(240 cellular phones programmed, 600 cellular phones tested)
d.More than one of the above would be on Shantala's production possibilities frontier.
5) Assume a firm in a competitive industry is producing 800 units of output, and it sells
each unit for $6. Its average total cost is $4. Its profit is
a. -$1,600.

6) Figure 9-10. The figure applies to Mexico and the good is rifles.
When trade takes place, the quantity Q2 - Q1 is
a.the number of rifles bought and sold in Mexico.
b.the number of rifles produced in Mexico.
c.the number of rifles exported by Mexico.
d.the number of rifles imported by Mexico.
7) Scenario 14-5
A study sponsored by the Food Consumer Safety Board found that consumption of
irradiated tomatoes increased the health of laboratory rats. As a result of national press
coverage of the report, the demand for irradiated tomatoes increased dramatically.
Organic farmers were able to switch from organic production of tomatoes to irradiated
production with no additional cost. Assume that the tomato market satisfies all of the
assumptions of perfect competition.
If the increased production of irradiated tomatoes caused a rise in the marginal
transportation costs of moving irradiated tomatoes to market, the
a.short-run market supply curve for irradiated tomatoes would be affected but not the
long-run market supply.
b.long-run market supply curve for irradiated tomatoes would be perfectly elastic.
c.long-run market supply of irradiated tomatoes would be downward sloping.
d.long-run market supply of irradiated tomatoes would be upward sloping.

equilibrium?
a.Impose a tax greater than the value of the technology spillover.
b.Not allow production of any product that causes a technology spillover.
c.Provide a subsidy equal to the value of the technology spillover.
d.Require producers to "clean up" any spillover that results from their production
process.
15) When Ukraine trades with Italy,
a.both countries are likely made better off.
b.only Italy benefits since Ukraine can produce all goods at a higher level of quality
