Unformatted text preview: 69 Problems on Supply and Demand. Problem 3.1. When the price of fresh fish rises in the local supermarket, the quantity of fresh fish sold decreases. Is this a decrease in the quantity demanded of fresh fish or is it a decrease in the demand for fresh fish? Problem 3.2. When the price of sneakers rises the quantity of sneakers produced increases. Is this an increase in the quantity supplied of sneakers or is it an increase in the supply of sneakers? Problem 3.3.

Q D , measured in tons, is the quantity demanded of fresh fish. Q S , measured in tons, is the quantity supplied of fresh fish. (i) On a graph with the per unit price p measured on the vertical axis and the quantities demanded and supplied, Q D and Q S , measured on the horizontal axis, draw both the demand curve and the supply curve for the fresh fish market. Clearly label both axes. (ii) Suppose the per unit market price is p = \$6 per ton of fresh fish. At this price does the market clear? If not, then is there an excess quantity demanded or an excess quantity supplied? How big is this excess? Would you expect the market price to change? If so, then which way does the price change; up or down? (iii) Suppose the per unit market price is p = \$3 per ton of fresh fish. At this price does the market clear? If not, then is there an excess quantity demanded or an excess quantity supplied? How big is this excess? Would you expect the market price to change? If so, then which way does the price change; up or down?...
