6. Data on two individuals' preferences for a public good are reflected in the table below.PA and PB represent the prices individuals A and B, the only two people in the society,are willing to pay for the last unit of a public good, rather than do without. (Hint: SeeFigure 4.5)QuantityPBQdPriceQsPPA2$S =EMC8$12$1137310987456.552$6434D-MB7213a) Complete the table above showing the collective willingness to pay for the publicgood in this society. Then, fill with appropriate values in the curves in the diagram.b) Given the supply schedule for this public good as shown by the Q: column, what is theoptimal quantity of this public good?And what is the optimal price?

The equations below represent the demand and supply curves for annual gym memberships in a city. qD= 500 − 2p, qS=0.5p − 50 Because physical activity leads to better health, the city estimates that each annual gym membership saves $30 of public spending on healthcare per year (a positive externality). a. In a graph, show the market and the socially optimal equilibria for annual gym memberships in this city. Does the market equilibrium result in under- or over-consumption of memberships? What is the deadweight loss associated with the market failure in this situation? b. Would you recommend this city to implement a subsidy (a negative Pigouvian tax) to correct this market failure? If so, how much would be the subsidy per unit? What would be the effects of your proposed policy on the quantity, price, and aggregate welfare?
Refer to the diagrams below in which figures (a) and (b) show demand curves reflecting the prices Alvin and Elmer are willing to pay for a public good, rather than do without it. If the marginal cost of the optimal quantity of this public good is $6, the optimal quantity must be: $12 10 Alvin (a) 4. 2. 4. $12 10 Elmer 6. 4. (b) 2.
Draw a graph that models a positive externality in consumption (label and clearly explain graph) Explain: i) The difference between the competitive equilibrium quantity and the socially optimal level quantity. ii) A possible intervention to bring the competitive equilibrium quantity closer to the socially optimal quantity. iii) An example of a setting in which this type of externality might occur (explain clearly how/why this externality happens).
On the basis of the three Individual demand schedules below, and assuming these three people are the only ones in the society, determine (a) the market demand schedule on the assumption that the good is a private good and (b) the collective demand schedule on the assumption that the good is a public good Instructions: Enter your answers as whole numbers (in the gray-shaded cells).

Parks confer many external benefits on society: open space, trees that reduce pollution, and so on. Therefore, the market equilibrium quantity of parks is not equal to the socially optimal quantity. The following graph shows the demand for parks (their private value), the supply of parks (the private cost of producing them), and the social value of parks, including both the private value and external benefits. Use the black point (plus symbol) to indicate the market equilibrium quantity. Next, use the purple point (diamond symbol) to indicate the socially optimal quantity.
3. Now reconsider the issue of soybeans from the perspective of Chinese consumers. Assume you are a Chinese consumer who drinks soymilk each day. Demonstrate using a graph how your consumption of soymilk differs from the socially optimal level. Is the price you pay for soymilk in current market conditions the correct amount, too high, or too low? Why? Ensure that you label your graph correctly (all curves, axes, price and quantities labeled). Show the deadweight loss of soymilk consumption, and what price should be charged for soymilk to move the amount of soymilk you drink to the optimal level.
5.. "Since a public good is enjoyed by all members of society, willingness to pay for the good will not diminish as the amount produced increases." Evaluate and use an example to support your answer. This statement is (correct incorrect). Public goods face (increasing, constant, diminishing ) returns like any other good. Consider the number of highways in a town, for example. Citizens of a town are very willing to pay for the first highway, as it produces large gains to the town. Successive highways produce (more and more, less and less ) willingness to pay because the citizens face lower and lower gains from the increased number of highways. In a town of, say 20,000, 15 highways (would, would not) produce much more benefit than just 2 or 3 highways because of ( increasing, constant, diminishing ) returns.
Currently, 160 units of a pure public good have been provided. Alex’s demand curve for the public good is 40 −0.2q. If the price of the good is 8.5, what quantity of the public good, q, would Alex be willing to purchase?
4. Efficiency in the presence of externalities Cars impose many external costs on society: carbon dioxide emissions that contribute to air pollution, congestion on roadways, and so on. Therefore, the market quantity of cars is not equal to the efficient quantity. The following graph shows the private demand for cars, the private supply of cars, and the social supply of cars, which incorporates both private costs and external costs. Use the black point (plus symbol) to indicate the market quantity. Next, use the purple point (diamond symbol) to indicate the socially optimum quantity. Note: Drop lines will extend to both axes automatically. DERIVATE QUARKET O5OCIAL SSOCIAL SPRVATE QUANTITY OF CARS From society's standpoint, the market is producing cars. This is an example of of resources. PRICE OF CARS
The market for some public good consists of only two consumers, Elena and Talia. The marginal cost of providing this good is described by MC = 3 + 5Q. Elena's MWTP = 40 - 3Q and Talia's MWTP = 10 - 2Q. What is the socially-efficient quantity of this good? Round to the nearest whole unit
There are two people. Each person's demand for a public good is P = 20 - Q. The marginal cost of providing the public good is given by MC2 = $12 (MC is not $24). The above graph summarizes the relevant information. The total demand for the two workers shown above is the vertical sum of the demand curve for each worker.(a) What is the socially efficient quantity of the public good?(b) How much will each person have to pay per unit to provide the socially efficient quantity?(c) What is the consumer surplus for each person based on the quantity determined in (a) and the price determined in (b)?(d) Given that this is a public good, if either one of the two people does not pay the price you have stated in (b), can they be prevented from consuming the good?
2. Efficiency in the presence of externalities Trucks impose many external costs on society: heavy air and noise pollution, traffic safety issues and road congestion, and so on. Therefore, the market equilibrium quantity of diesel trucks does not equal the socially optimal quantity. The following graph plots the demand for diesel trucks (their private value), the supply of diesel trucks (the private cost of producing them), and the social cost of diesel trucks, including both the private cost and external costs. Use the black point (plus symbol) to indicate the market equilibrium quantity. Next, use the purple point (diamond symbol) to indicate the socially optimal quantity.
