The graph shows the marginal private benefit from a law degree and the marginal cost of obtaining a law degree. The marginal external benefit is $16,000 per law graduate per year. Suppose the government offers vouchers to those who enroll at a law school. Draw the marginal social benefit curve. Label it MSB. Draw an arrow at the efficient number of students to show the value of the voucher that achieves the efficient number of students. The value of the voucher that achieves the efficient number of students is $ per student. >>> Remember that the quantity given on the y-axis is in thousands of dollars. 48- 40- 32- 24- 16- 8- Price and cost (thousands of dollars) 0 S-MC 10 30 40 Students (thousands per year) >>> Draw only the objects specified in the question. 20 D=MB 50

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

Externalities Do you think that there would be external effects associated with Water from a uranium mine leaking into Kakadu National Park? If so, what would be the nature of the external effects? Can you think of policies that might deal with each external effect (that is, improve social wellbeing)?

A small town provides a fireworks display, which is a public good, every fourth of July. For simplicity, assume the town only has two residents: Hayden and Madison. Their demands for the fireworks display are illustrated in the figure to the right. Construct the market demand curve for this public good. 8.00 7.50- 7.00- 6.50- 6.00- 5.50- 5.00- 4.50- Use the line drawing tool to draw the market demand curve (DMarket) for the fireworks display. Properly label this line. 4.00- DMadison DHayden 3.50- Carefully follow the instructions above, and only draw the required objects. 3.00- 2.50- P 2.00- 1.50- 1.00- 0.50- 0.00- 2 4 6 8 10 12 14 16 Quantity (number of fireworks) Price (dollars per firework)

Suppose there are only two consumers in the market for a public good. The figure to the right shows marginal benefit lines for a public good for the two individuals, Andrew (A) and Brenda (B). Use the line drawing tool to draw and label the social marginal benefit line. Make sure that the line extends from quantity level 0 to 10 as the private marginal benefit lines do. Carefully follow the instructions above, and only draw the required object. Marginal Benefit, Marginal Cost ($) 20- 18- 16- 14- có + 2- 0- -O 0 1 MC 2 3 4 5 6 7 8 9 Quantity of a Public Good MBA MBB 10 11 12 Q

Policymakers realize that, although education creates a positive benefit for those who obtain it, it also creates external benefits for the community where the educated individual resides. The graph depicts the marginal social cost (MSC) and the marginal social benefit (MSB) associated with education. On the graph, move the point, P, to the point representing the optimal level of education. Dollars (thousands) 100 90 80 70 60 50 40 30 20 10 0 0 2 4 MSC MSB 6 8 10 12 14 16 18 20 22 Years of schooling optimal schooling: 14 What is the socially optimal number of years of schooling for each citizen? years

Explain the concept of externalities; include an example, as well as how the government takes action to correct it.

Question is in the photo! Thank you so much!

Identify at least one positive externality from running a donut shop. Identify at least one negative externality from running a donut shop. Explain how these positive and negative externalities could impact the donut shop’s profits. (Hint: think subsidy for positive externality and tax for negative externality.) Draw two graphs that show the price of donuts before and after the positive and negative externality impacted the price of your donuts.
