Answer to Question 1

a) Street lights are a public good, so a private company would provide zero street lights. The company would provide zero because everyone would free ride, that is, no one would voluntarily pay for the street lighting. Because the company knows that no one will pay, it will not provide any street lights.
b) The efficient quantity is 3 street lights per block because that is the quantity that equates the marginal social benefit to the marginal social cost.

Answer to Question 2
