3. Assume that there is a world price for corn and that the domestic market has the usual downward sloping demand curve and upward sloping supply curve. Which of the following statements is true for a country that exhibits an absolute disadvantage in the production of corn?

a. The country will import corn and consumer surplus will increase relative to the no trade situation.
b. The country will import corn and producer surplus will increase relative to the no trade situation.

4. Two shops in Newtown, "Artisan Pens" and the Thrift Shop, are deciding whether to hire a security guard. The security guard represents a public good in that the guard will provide deterrence to both stores. The cost of hiring a guard is $20 in total or $10 per store if the cost is shared. Each store will benefit from the presence of a security guard by reducing theft by $12. The payoffs for the Thrift Shop are shown first in each cell. If the payoff matrix is given by:

In the Nash equilibrium:

a. A guard will be hired.
b. No guard is hired.
c. One store hires the guard and both benefit from the presence of the guard.
d. Neither player has a dominant strategy and there are no Nash equilibrium.
e. More information is required to answer the question.

Suppose individuals A and B have the following demand curves for a public good: QA = 40 - 2p and QB = 40 - p, where Q is the amount of the public good.If the marginal cost of production is constant and equal to 30, the quantity produced in the competitive equilibrium would equal ____ and the efficient outcome is equal to ____:
a. 0,10
b. 10,10
c. 10,20
d. 10,30
e. None of the above
