National Public Radio (NPR) is a public good. The cost (supply) of each "unit" of NPR is P=2. Derek's valuation for each unit of NPR (demand) is given by PD=10–Q, and Kim's valuation is given by PK=4–0.25Q. The total social valuation (demand) of NPR is PS=Answer-AnswerQ. The socially optimal amount of NPR is Answer units. Without intervention, the private market would lead to an Answer of NPR.

(Optimal Provision of Public Goods) Using at least two individual consumers, show how the market demand curve is derived from individual demand curves (a) for a private good and (b) for a public good. Once you have derived the market demand curve in each case, introduce a market supply curve and then show the optimal level of production.
Consider a situation where Barack (B) and Michelle (M) have demands for a public good that can be represented by the following functions: D_B: Q_B = 24 - 2P_B D_M: Q_M = 18 - 2P_M If Barack and Michelle are the only two consumers of this public good and the supply function for the good is: S: Q = -1 + P What is the socially optimal quantity of the public good?
Which of the following is true if good x is an externality exhibiting good. If consumption of good x by person 1 exhibits a positive externality, then consumption of good x by person 2 must also exhibit a positive externality. Consumers consume too much good y relative to what is socially optimal. Consumers consume too much good x relative to what is socially optimal. Equilibrium consumption of the good is not Pareto efficient.
The cost (supply) of each "unit" of NPR (National Public Radio) is P=9. Derek's valuation for each unit of NPR (demand) is given by Pp=20-2Q, and Kim's valuation is given by Pk=10-Q. The social valuation of NPR is Ps= Q. The socially optimal amount of NPR is units. Without intervention, the private market would lead to an 수 of NPR. Suppose the government decides to subsidize NPR in order to achieve the socially optimal amount of NPR. The total demand function is Qr= The appropriate subsidy is $ (include 2 decimals) per unit of NPR
Military Defense is a public good. The cost (supply) of each "unit" of military defense is P=3. Kim's valuation for each unit of defense (demand) is given by PK=10–Q, and Derek's valuation is given by PD=5–0.5Q. The resulting social demand function is PS=15-1.5Q.What is the socially optimal allocation of military defense?
The Coase theorem states that if transactions costs are low, property rights are assigned, and parties understand how much they value something, private bargaining will result in an efficient solution to the problem of externalities. government intervention is always needed if externalities are present. a free market equilibrium is the best solution to address externalities. assigning property rights is the only thing the government should do in a market economy.
Suppose there are two residents in a neighborhood, and you know both of their demand curves for a public good. What would you have to do in order to figure out what the social demand curve? a-Subtract the demand of the person with the higher valuation of the public good from the demand of the person with the lower valuation of the public good b-Add their demand curves together c-Multiply the two demand curves together d-Subtract the demand of the person with the lower valuation of the public good from the demand of the person with the higher valuation of the public good
Consider a product market with three consumers X, Y and Z with demand function QX = 6 – PX, QY = 3 – ½PY and QZ = 12 – PZ respectively, where P is the price in dollars and QX, QY and QZ are the quantities demanded by Consumer X, Y and Z respectively. If the product is public good, obtain the marginal social benefit function and draw the diagram. Determine the optimal quantity of the product in the market if the marginal cost of the product is constant at (a) $4, (b) $9 and (c) $16.

Education confers many external benefits on society: a higher-paid workforce, more technological innovation, a more informed electorate, and so on. Therefore, the market equilibrium quantity of education is not equal to the socially optimal quantity. The following graph shows the demand for education (its private value), the supply of education (the private cost of producing it), and the social value of education, 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.
Suppose that it costs 500 per day to search for chanterelle mushrooms at Pt.Reyes National Seashore.On an average day, the total weight of mushrooms M found at Pt. Reyes is M = 100x - x2 pounds where x is the number of people mushroom hunting on that day. Chanterelles can be sold for $80 per pound. How many more people will go mushroom hunting than is socially optimal ?
Suppose 15 people each have the demand Q=220 - 40P for streetlights, and 10 people have the demand Q = 180 - 20P for streetlights. The cost of building each streetlight is $8. If it is impossible to purchase a fractional number of streetlights, how many streetlights are socially optimal?
