2) On holiday weekends thousands of people picnic in state parks. Some picnic areas
become so overcrowded the benefit or value of picnicking diminishes to zero. Suppose
that the Minnesota State Park Service institutes a variable fee structure. On weekdays
when the picnic areas get little use, the fee is zero. On normal weekends, the fee is $8

b.the government prevents markets from doing so.
c.property rights are not well established for clean air.

5) Suppose you like to make, from scratch, pies filled with banana cream and vanilla
pudding. You notice that the price of bananas has increased. As a result, your demand
for vanilla pudding would

Suppose that Abdul opens a coffee shop. He receives a loan from a bank for $100,000.
He withdraws $50,000 from his personal savings account. The interest rate on the loan

a. $8,000.
b. $4,000.
c. $2,000.
d. $1,000.
7) Assume that Maya and Miguel can switch between producing mixers and producing
toasters at a constant rate.
Maya should specialize in the production of
a.mixers and Miguel should specialize in the production of toasters.
b.toasters and Miguel should specialize in the production of mixers.
c.both goods and Miguel should specialize in the production of neither good.
d.neither good and Miguel should specialize in the production of both goods.
8) Figure 17-5. Two companies, ABC and QRS, are sellers in the same market. Each
company decides whether to charge a high price or a low price. In the figure, the dollar
amounts are payoffs and they represent annual profits for the two companies.
Refer to Figure 17-5. If the two companies make their pricing decisions independently,
then it is likely that QRS will
a.charge a low price only if ABC charges a low price.
b.charge a low price only if ABC charges a high price.
c.charge a low price regardless of whether ABC charges a high price or a low price.
d.None of the above are correct.

What are the concentration ratios for each industry? Which is more competitive?
17) If the U.S. could produce 5 televisions per hour of labor and China could produce 3
