1. Assume the US market of sunflower oil was described by the following domestic supply and demand equations: QDUS = 5000 - 2 P and QSUS = -3000 + 8 P where QDUS and QSUS represent the quantities demanded and supplied (in billions of metric tons) and P is the price per metric ton of sunflower oil (in $). Now add this information: In 2008, China entered into the World Trade Organization and became the largest importer of US sunflower oil. Assume the Chinese import demand for sunflower oil from the US in 2008 was QDCHINA = 12000 - 10 P Given your calculations in questions 4-7, what were US sunflower oil producer revenues?
2. $10,000,000
3. $12,000,000
4. $5,000,000
5. $11,500,000

QUESTION 9

1. The extended demand function of good X is: QDX = 1200 - 10 PX + 20 PY + 0.2 M where: QDX = quantity demanded of good X, PX = Price of good X, M = Average consumer income, and PY = Price of related good Y (related in consumption to good X). If M = 20,000, PY = 10, and PX = 400; then QDX = __? and if M = 20,000, PY = 10, and PX = 420 then QDX = __?
2. 1900, 1800
3. 1800, 1700
4. 1400, 1200
5. 1800, 1800

QUESTION 10

1. The extended demand function of good X is: QDX = 1200 - 10 PX + 20 PY + 0.2 M where: QDX = quantity demanded of good X, PX = Price of good X, M = Average consumer income, and PY = Price of related good Y (related in consumption to good X). In problem 9, you calculated QDX if M = 20,000, PY = 10, and PX = 400 and you calculated QDX if M = 20,000, PY = 10, and PX = 420. Using the two prices for PX and your calculated two quantities demanded of good (QDX), what is the value of the price elasticity of demand between these two points on the demand curve for good X (using the arc elasticity formula).
2. -3.154
3. -2.230
4. -1.375
5. -5.872
