10. If supply changes from S2 to S1 and demand changes from D1 to D2     (a) equilibrium price falls to $ 14.     (b) equilibrium quantity increases to 16.     (c) equilibrium price increases to $19.     (d) supply has increased. 11. if demand changed from D1 to D2 as a result of an increase in buyers' income this product is     (a) a normal good.     (b) a free good.     (c) an inferior good.     (d) a complementary good. 12. If demand for this product changed from D2 to D1 as a result of a increase in price of a related product, then these two products are     (a) complements.     (b) inferior goods.     (c) economic goods.     (d) substitutes.     (e) public goods.

Consider two markets: the market for waffles and the market for pancakes. The initial equilibrium for both markets is the same, the equilibrium price is $6.50, and the equilibrium quantity is 35.0. When the price is $9.75, the quantity supplied of waffles is 57.0 and the quantity supplied of pancakes is 101.0. For simplicity of analysis, the demand for both goods is the same. Using the midpoint formula, calculate the elasticity of supply for pancakes. Please round to two decimal places. Supply in the market for waffles is

Combine parts 1 and 2. Suppose that the FDA increase regulation of coffee, and a reputable study is published indicating that coffee drinkers have higher rates of Alzheimer’s. What with the combined impact have on the equilibrium price and quantity of coffee? Explain your reasoning and show graphically. Make sure you think this through carefully!

Consider the weekly supply of gasoline in Figure 1. How much gasoline will producers wish to sell if the price of a gallon of gasoline is $1.20?       A) 100K gallons       b) 140K gallons       C) 236K gallons       D) 308K gallons

Question 2 (5 marks) No words allowed, only a diagram with annotations To answer this question only a diagram with annotations is required. Suppose apples and pears are substitutes in consumption. An outbreak of Grumpy Granny Smith fungus has a devastating effect on the size of the apple crop. Show on a diagram how this will affect the market for pears. Indicate how the equilibrium price and equilibrium quantity of pears will change. The direction of any changes should be indicated using arrows. S hp Please turn over. FTSE jse 40

43) Suppose we observe a large increase in the price of corn but the quantity of corn sold stays the same. What is the most plausible explanation (or combination of explanations) below? a) A drought occurred in corn-growing regions. b) A drought occurred in corn-growing regions and a medical report was issued that corn is good for your health. c) A drought occurred in corn-growing regions and a medical report was issued that corn is bad for your health. d) A few fertilizer was invented that doubles corn yields. e) A new fertilizer was invented that doubles corn yields and a medical report was issued that corn is bad for your health. 44) Suppose we observe that the price of paper has increased and the quantity of paper sold has decreased. What is the most plausible explanation? a) Consumers demand less paper because of increased use of the Internet. b) The price of pens and pencils increased dramatically. c) The number of children in schools decreased dramatically. d) More logging for…
