The hypothetical city of Hurstville is trying to decide how many city beautification projects should be approved each year. These projects involve planting gardens, commissioning murals, and building fountains. The city has two types of citizens. Type B citizens appreciate beauty more than type A citizens. There is an equal number of each type of citizen. The accompanying schedule depicts each type of citizen's marginal benefit for city beautification projects. The average cost of each project is $400. Use the information in the schedule to answer the questions. Marginal Benefit Schedule Q MBA MBB 0 400 600 1 300 500 2 200 400 3 100 300 4 0 200 5 0 100 6 0 0 What is the optimal quantity of city beautification projects? 2 3 4 1 City beautification is a public good because: it is rival in consumption and nonexcludable. it is nonrival in consumption and nonexcludable. it is nonrival in consumption and excludable. it is rival in consumption and excludable.

Step 1
This is done by summing the marginal benefit for Type A citizens ($MB_A$) and Type B citizens ($MB_B$) for each quantity (Q). $MB_{Total} = MB_A + MB_B$ Q | $MB_A$ | $MB_B$ | $MB_{Total}$ ------- | -------- | -------- | -------- 0 | 400 | 600 | 1000 1 | Show more…
