Suppose there are two consumers of a public good, one with a marginal benefit of 10-Q; the other a marginal benefit of 30-2Q, where Q is the quantity of that public good. The public good can be provided with MC = 20.

a) how many quantities of the public good will be provided assuming that the low-demand consumer will free ride on the high-demand consumer?

b) what is the sum of total consumer surplus to the two consumers under a private market where the firm price at MC, assuming that one of the consumer free-ride on the other one?

Suppose there are two consumers of a public good, one with a marginal benefit of 10-Q; the other a marginal benefit of 30-2Q, where Q is the quantity of that public good.

Public goods consider an economy with two consumers, Ben and joe. there is public good in this economy in a form of tomado series. Ben's demand for the tomado series is given by p=10-Q, and Joe's demand for tomado series is p=8-2Q. The marginal cost for providing tomado series in the markets is constant at MC=9. i) Which two properties must be satisfied for series to qualify to be public good? ii) Is there a problem for free rider problem?...

Consider the demand for a public good estimated for two sets of consumers: P1 = -0.5Q + 10 P2 = -0.25Q + 5 where P is the price that each consumer is willing to pay at difference levels of quantity. The cost of providing one additional unit of this public good is $4 (e.g., marginal cost (MC) = $4) a) Derive the equation of the market demand curve for this public good. Hint: Remember that in this case you have...

Suppose the market demand function is Q = 120 – 2P, and the marginal cost (in dollars) of producing the product is MC = Q, where P is the price of the product and Q is the quantity demanded and/or supplied. How much would be supplied by a competitive market? (Hint: In a perfect competition, the profit maximization condition is MR=P=MC) Compute the consumer surplus and producer surplus. Show that the economic surplus is maximized.

The social marginal cost of producing a certain public good is $20 per unit. Society consists of three individuals. Persons 1, 2, and 3 value the public good according to the following marginal benet schedules: MB1 = 60 − Q, MB2 = 120 − 3Q, and MB3 = 150 − 2Q, where Q denotes the number of units of the public good provided. Assume that, at any quantity Q that makes a person's marginal benet become negative, that person's MB...

A public good has a marginal cost of $100 per unit. There are four people in the population who have marginal private benefits from the public good given by 50−Q, 100−3Q, 25−Q, and 65 − 2Q respectively. a) What is the efficient amount of the public good?
