(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.

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 PX = 6 - QX, PY = 12 - QY and PZ = 18 - QZ 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) $3, (b) $9 and (c) $21.
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?
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.
Consider a two-good economy with one private and one public good. There are four consumers in this economy who contribute to public good provision. The price of the private good is $1 and the demand function of the public good for each consumer is as follows: p1 = 20 - 2G, p2 = 30-(5/10)G, p3 = 100-(G/2) and p4 = 60-G where G is the number of units of the public good and p^i is the price of each unit for consumer i in dollars. The cost of providing one extra unit of the public good is (alpha). (a) With 170 < alpha < 210, what is the optimal level of provision of the public good? Show the optimal point on a graph. (b) Is there a possibility that the public good is not supplied at all? Why? (c) If the public good is not supplied at all, what is the size of the deadweight loss due to this market failure? (d) If at least one person contributes, for what values of the public good will be supplied?
b) Consider agent A with (inverse) demand curve for the public good and agent B with inverse demand , where prices are measured in £ per unit. The marginal cost of producing the public good is £10 per unit. What is the Pareto efficient level of the public good? Explain. Illustrate in a graph.

True or False? For a perfectly competitive market (with no externalities) where a positive per unit tax has been imposed by the government, the sum of consumer surplus, producer surplus, and tax revenue is always less than the sum of consumer surplus and producer surplus before the tax is imposed. If true, is it always the case that government intervention reduces total social welfare? If false, provide a numerical example where a positive per unit tax increases total social welfare in a perfectly competitive market (with no externalities). Briefly explain
The accompanying table relating to a public good provides information on the prices Young and Zorn are willing to pay for various quantities of that public good. These two people are the only members of society. Determine the price that society is willing to pay for the public good at each quantity of output. If the government’s marginal cost of providing this public good is constant at $7, how many units of the public good should government provide? Why not less? Why not more?
Suppose the marginal cost of a pure public good increases as more is purchased by a community. Prove that the Lindahl equilibrium will result in a budget surplus at the efficient annual output of the pure public good
