The following is a Table that contains the demand and supply schedules of chocolate ice-creams. Price (cents per ice-cream) $0.90 0.80 0.70 0.60 0.50 0.40 Quantity Demanded (millions per day) 123456 4 6 Quantity Supplied (millions per day) 7 6 5 4 3 2 a) If there is no tax on ice-creams, what is their price and how many are produced and consumed? b) If a tax of $0.20 cents is imposed on every ice-cream consumed, what happens to the price of an ice-cream and the number produced and consumed? Illustrate the effects of this policy on the market for chocolate ice-creams. c) How much tax does the government collect and who pays it?

(Figure: The Blu-ray Disc Rental Market) Use Figure: The Blu-ray Disc Rental Market. If the rental price of Blu-ray discs rises from $5 to $7:   Question 2 options: v   supply will increase from 50 to 70 rentals per weekend.   the quantity demanded will decrease from 50 to 30 rentals per weekend.   the quantity supplied will increase from 50 to 60 rentals per weekend.   demand will decrease from 50 to 30 rentals per weekend.

4. In order to reduce farm output, raise farm prices, and thus raise farm incomes (revenues), the government pays farmers to set aside a portion of their land from production. Using a graph, explain in terms of the elasticity of demand for farm products why farmers may be better-off when harvests are low even if we ignore the money they receive from the set-aside program.

13. The table below gives part of the supply schedule for personal computers in the United States. Price Quantity Supplied before tech change Quantity Supplied after tech $1,100 $900 12,000 8,000 change 13,000 9,000 a) Calculate the price elasticity of supply when price rises from $900 to $1,100 using the arc elasticity formula (the midpoint method). b) Now suppose that technology changes such that at every price, 1000 more computers are supplied. Now, as prices rise from $900 to $1,100, is the elasticity of supply smaller than, larger than, or equal to the elasticity in part a)? c) Does the change in b) change the slope of the supply curve? Are slope and elasticity the same thing? Explain.

2. The following graph shows the demand and supply for i-Pods. Price 100 80 60 40 20 0 0 80 160 240 Quantity of i-pods 320 is D 400 a. What is equilibrium price and quantity? b. Suppose that a $20 per unit sales tax is placed on the product. What is the new equilibrium price and quantity? c. What proportion of the tax is paid by the consumer, and what proportion is paid by the seller in this case?

7. Effect of a tax on buyers and sellers The following graph shows the daily market for jeans. Suppose the government institutes a tax of s20.30 per pair. This places a wedge between the price buyers pay and the price sellers receive. 100 90 80 Demand Supply 70 50, 50 60 50 Тах Wedge 40 30 20 10 10 20 30 40 50 60 70 B0 90 100 QUANTITY (Pairs of jeans) Fill in the following table with the quantity sold, the price buyers pay, and the price sellers receive before and after the tax. Quantity Price Buyers Pay Price Sellers Receive (Pairs of jeans) (Dollars per pair) (Dollars per pair) Before Tax After Tax Using the data you entered in the previous table, calculate the tax burden that falls on buyers and on sellers, respectively, and calculate the price elasticity of demand and supply over the relevant ranges using the midpoint method. Enter your results in the following table. Tax Burden (Dollars per pair) Elasticity Buyers Sellers The burden of the tax falls more heavily on the elastic…

Figure 4-3 Price $20 18 16 14 12 10 8 4 2 10 20 30 40 50 60 70 80 90 100 Quantity 2. Refer to the Figure 4-3. If price in this market is currently S14, what would happen? a. Quantity supplied would be 40 and quantity demanded would be 60. b. Quantity supplied would be 60 and quantity demanded would be 40. c. Quantity supplied would be 50 and quantity demanded would be 50. d. Quantity supplied would be 70 and quantity demanded would be 30.

8. Suppose we want regular cars to be gradually replaced by electric cars. There are several kinds of government interventions that could be used to make this happen, or at least to push the car market to produce and sell more electric cars. Explain how a tax could be used for this purpose, and then explain how a subsidy could be used for this purpose.
