A) The social supply curve is to the left of the private supply curve. B) The social supply curve is to the right of the private supply curve. C) The social demand curve is to the left of the private demand curve. D) The social demand curve is to the right of the private demand curve.

Bill’s demand for hamburgers (a private good) is Q = 21 − 6P and Ted’s demand is Q = 6 − 3P. Write down an equation for the social marginal benefit of the consumption of ham- burger consumption. Now suppose that hamburgers are a public good. Write down an equation for the social marginal benefit of hamburger consumption.

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.Multiply the two demand curves together   B.Add their demand curves together   C.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   D.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

Use a supply and demand graph to show a good which should be illegal owing to it's negative externality.

Consider the above graph. Is there an externality present in this market? If so, what kind?   No, there is no externality.   Yes, a negative externality.   Yes, a positive externality.

The following is a copy of the information from Question 1: Consider Product NE, which has a negative externality associated with its production and use ( i.e., the “Incidental Cost” ( IC) of each unit of Product NE is greater than zero). You are told that :                              * The “Efficient” Output of Product NE = 9000 units                              * The Free-Market Equilibrium Output of Product NE = 10,000 units                              * The Consumer’s Surplus + Producer’s Surplus on Unit Number 6000 ( i.e., on that one unit ALONE) is equal to $ 70 ( i.e., the sum of CS + PS = $ 70)                              * The Cumulative Surplus on the first 9000 units produced is equal to $ 175,000 ( i.e., the sum of the surplus( to society) on ALL 9000 units adds up to $ 175,000) Is the Cumulative Surplus on the first 10,000 units ( i.e., ALL 10,000 units together) greater than $ 175,000, less than $ 175,000, or exactly equal to $ 175,000 ?   a. Greater Than $…

If the government subsidizes vaccination against influenza to internalize the externality, should it impose the subsidy on consumers or producers of flu vaccines? How large should the subsidy be? How much less per flu vaccine would patients (i.e., consumers) pay? How much more would manufacturers (i.e., producers) of flu vaccines receive?

Public wifi hotspots grant many external benefits on society: more equitable access to the internet, increased educational opportunities, and so on. Therefore, the market equilibrium quantity of public wifi hotspots does not equal the socially optimal quantity. The following graph plots the demand for public wifi hotspots (their private value), the supply of public wifi hotspots (the private cost of producing them), and the social value of public wifi hotspots, 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.

Consider the market illustrated in the figure to the right. Supply curve S₁ represents the private cost of production and demand curve D₁ represents the private benefit from consumption. Suppose consumption of this good creates a positive externality. Show how the externality affects the market. 1.) Use the line drawing tool to draw either a new supply (S₂) or demand (D₂) curve incorporating the positive externality in consumption. Properly label this line. 2.) Use the point drawing tool to indicate the market equilibrium price and quantity. Label this point 'Market equilibrium'. 3.) Use the point drawing tool to indicate the efficient equilibrium price and quantity. Label this point 'Efficient equilibrium'. Carefully follow the instructions above, and only draw the required objects. Price Quantity S₁ D₁ N
