6. Initially the market demand for applesauce is Q_D = 20 - P and the supply for applesauce is Q_S = P - 12. Suppose the price of apples then increases.

Use the following information to answer the following two questions.

A market has only two groups of firms. One group employs innovative technologies while the other still uses a conventional means of production. The group with conventional technology has the supply curve: ??_??1 = ?? - 180. The group with innovative technology has the supply curve: ??_??2 = ?? - 150. There is only one group of consumers and they have the demand curve: ??= 750 - 2??.

7. If initially only the firm with the innovative technology is producing, what will be the market equilibrium quantity?

a. Q = 200

b. Q = 350

8. Now suppose both groups are producing. If you are asked to graph the market supply curve, which of the following will be the kink point (Q,P) for this market supply curve?

a. (-30,150)

b. (0,120)

c. (30,180)

d. (0,150)

Use the following information to answer the next three questions:

Keynesland is a small open economy that produces fish. Its domestic demand is given by ?? = 200 - 2?? and its domestic supply is given by ?? = 2?? - 40. The world price of fish is $40 per unit of fish.

9. Suppose the government implements an import quota of 16 units. What will be the domestic price?

a. $44

b. $48

c. $56

d. $50

10. Suppose that, instead of the quota described in the previous problem, the government implements an import tariff that will increase the price of each unit of fish by $10. Relative to this tariff of $10, if the government were to increase the tariff by an additional $1, this would ______ government tariff revenue and _______ consumer surplus.

a. decrease; decrease

b. decrease; increase

c. increase; decrease

d. increase; increase

11. If the government implements an import tariff that increases the price of each unit of fish by $10, then what is the deadweight loss?

a. $100

b. $160

c. $200

d. $240

Use the following information to answer the next two questions.

Ahmed and Bernard produce oranges and lemons. When their production is combined, it yields the following joint PPF:

12. Suppose Ahmed could produce up to 4 oranges if he spent all his time producing oranges. Given this information and the above PPF, Ahmed must therefore have the comparative advantage in producing:

a. oranges

b. lemons

13. Suppose Ahmed can produce up to 4 oranges or 5 lemons in the given time period. What must be Bernard's opportunity cost of producing one lemon?

a. 4/5 Oranges

b. 4/3 Oranges

c. 1 Orange

d. 3/2 Oranges

Use the following information for the next two questions.

Jimmy has a Mexican Restaurant and his two staple dishes are Tacos and Fajitas. We know that Jimmy has constant opportunity cost. He can produce at most 20 Fajitas or 50 Tacos. Jimmy has the opportunity to trade with a Taco Ring, a bigger company. The Opportunity Cost for Taco Ring is constant, and it can exchange 1 Taco for 1/5 of Fajita.

14. Who has the comparative advantage in producing tacos?

a. Jimmy

b. Taco Ring

15. Which of the following terms of trade would generate gains for both companies?

a. 1 fajita for 2.5 tacos

b. 1 taco for 0.5 fajitas

16. Who has the comparative advantage in producing articles?

a. Yasunari

b. Kenzaburo

17. Who has the absolute advantage in producing short stories?

a. $675

b. $400

c. $325

d. $200

a. 15

b. 30

c. 40

d. 50
