Table 3.9 illustrates the market's demand and supply for cheddar cheese. Graph the data and find the equilibrium. Next, create a table showing the change in quantity demanded or quantity supplied, and a graph of the new equilibrium, in each of the following situations:
(a) The price of milk, a key input for cheese production, rises, so that the supply decreases by pounds at every price.
(b) A new study says that eating cheese is good for your health, so that demand increases by at every price.
Price per pound | Qd | Qs |
---|---|---|
\(3.00 | 750 | 540 |
\)3.20 | 700 | 600 |
\(3.40 | 650 | 650 |
\)3.60 | 620 | 700 |
\(3.80 | 600 | 720 |
\)4.00 | 590 | 730 |
Table 3.8 shows the information on the demand and supply for bicycles, where the quantities of bicycles are measured in thousands.
Price | Qd | Qs |
---|---|---|
\(120 | 50 | 36 |
\)150 | 40 | 40 |
\(180 | 32 | 48 |
\)210 | 28 | 56 |
\(240 | 24 | 70 |
(a) What is the quantity demanded and quantity supplied at a price of ?
(b) At what price is the quantity supplied equal to ?
(c) Graph the demand and supply curves for bicycles. How can you determine the equilibrium price and quantity from the graph? How can you determine the equilibrium price and quantity from the table? What are the equilibrium price and the equilibrium quantity?
(d) If the price was , what would the quantities demanded and supplied be? Would a shortage or surplus exist? If so, how large would the shortage or surplus be?
What does a downward-sloping demand curve mean about how buyers in a market will react to a higher price?
Suppose there is a soda tax to curb obesity. What
should a reduction in the soda tax do to the supply of sodas and to the equilibrium price and quantity? Can you show this graphically? Hint: Assume that the soda tax is collected from the sellers.
