Consider the market for CD players, illustrated in the figure to the right. Suppose there are network externalities in this market such that the quantity of a good demanded grows in response to the growth of purchases by other individuals (as indicated by the demand curve "Demand" in the figure). Suppose that the price is initially $130 where the quantity demanded is 60 (thousand CD players per month). 200- Do 180- 160 Demand 140- If the price of CD players falls to $90, demand will increase to thousand CD 120- players per month.

- Explain the difference between a positive and a negative network externality. A network externality for a good is positive if O A. the substitution effect of a price change is larger than the income effect, but a network externality is negative if the income effect is larger than the substitution effect. B. consumption by others decreases a typical consumer's marginal utility from consuming the good, but a network extemality is negative if consumption by others increases a typical consumer's marginal utility from the good. c. the price is lower the more people own it, but a network externality is negative if the price is lower the fewer people own it. D. the quantity demanded is higher the more people own it, but a network externality is negative if the quantity demanded is lower the more people own it. O E. it has a complement, but a network effect is negative if it has a substitute. Give an example of each. An example of a positive network externality is the dermand for A. a work of…The following table shows three demand schedules for a person who likes toplay football and/or go swimming. In scenario S1, his income is $100,000 per yearand swimming cost $18 each. In scenario S2, his income is also $100,000 peryear, but the price of swimming rises to $22 per round. And in scenario S3, hisincome increases to $140,000 per year while swimming cost $22 per round.A. Use data under S1 and S2 to calculate the cross elasticity of demand for footballat all three prices. (Use the midpoint formula) Is the cross elasticity the same at allthree prices? What type of goods are football and swimming? Why?b. Use data under S2 and S3 to calculate the income elasticity of demand forfootball at all three prices. (Use the midpoint formula) Is the income elasticity thesame at all three prices?

Draw two sup- ply and demand diagrams (one for electric vehicles and one for petrol- powered vehicles) to show the impact of an electric vehicle subsidy. As- sume that an increase in electric vehicles sales reduces petrol powered vehicles by the same amount. On these diagrams show: (a) The quantity of both types of vehicles before the subsidy. (b) The quantity of both types of vehicles after the subsidy. (c) The deadweight losses in both markets before and after the subsidy. 4. is a fuel excise or an electric vehicle subsidy a better policy response to address externalities associated with driving? Your answer should draw on the answers above and could also include: Which policy is simpler to administer. How the two policies impact use of other forms of transport (like public transport or riding a bike). Which policy is fairer.

What is the quantity of automobiles demanded per year when the averageprice of an automobile is $15,000? When it is $25,000? When it is$35,000?b. Sketch the demand curve for automobiles. Does this demand curve obeythe law of demand?A city has built a bridge over a river and it decides to charge a toll to everyone who crosses. For one year, the city charges a variety of different tolls and records information on how many drivers cross the bridge. The city thus gathers information about elasticity of demand. If the city wishes to raise as much revenue as possible from the tolls,where wil lthe city decide to charge a toll: in the inelastic portion of the demand curve, the elastic portion of the demand curve, or the unit elastic portion? Explain.
