6) In a competitive market, the market demand is Q d = 60 - 6P and the market supply is s = 4P. A price ceiling of \$3 will result in a) A shortage of 18 units. b) A shortage of 30 units. c) A surplus of 30 units. d) A surplus of 12 units. e) neither a shortage nor a surplus. Answer: B 7) In a competitive market, the market demand is Q d = 60 - 6P and the market supply is Q s = 4P. The full economic price (How much a buyer willing to pay) under a price ceiling of \$3 is a) 6. b) 7. c) 8. d) 9. Answer: C 8) Suppose the demand for good X is given by Q d x = 10 + α x P x + α y P y + α M M. If α M is negative, then good y is: a) a normal good. b) an inferior good. c) a complement. d) a substitute. Answer: B 9) The supply function for good X is given by Q x s = 1,000 + P X - 5 P Y - 2P W , where P X is the price of X, P Y is the price of good Y and P W is the price of input W. If the price of input W increases by \$10, then the supply of good X a) will increase by 10 units. b) will increase by 20 units. c) will decrease by 10 units.
