6. At one time, sea lions were depleting the stock of steelhead trout. One idea to scare sea lions away from the Washington coast was to launch fake killer whales, which are predators of sea lions. The cost of making the first whale is $16,000 ($5,000 for materials and $11,000 for the mold). The mold can be reused to make additional whales, and so additional whales cost $5,000 each.

13. When Ross Perot ran for president as a third party candidate in 1992, he argued that free trade with Mexico would result in massive job losses in the United States because Mexican wages were so low. Which of the following is the best explanation of why few economists agreed with Perot?

19. Suppose people freely choose to spend 40 percent of their income on health care, but then the government decides to tax 40 percent of that persons income to provide the same level of coverage as before. What can be said about deadweight loss in each case?
Taxing income results in deadweight loss, and purchasing health care on ones own doesnt result in deadweight loss.
