[Strictly speaking, the word \"marginal" refers to innitesimal rates of change, but it is commonly used loosely to refer to discrete changes, as in the present case.] If only Adams is on the scene, what level of road repair would he choose? Explain in terms of marginal benets and marginal costs. Suppose Braun now builds a house on Lot B. Braun, coincidentally, has the same preferences about road repair as Adams. Fill in the marginal benet to Adams and Braun. What is the efcient amount of road repair? Explain how you determine this. Suppose that Adams and Braun choose the amount of road repair to pay for as a simultaneous move game. Write out the strategic grid, with the strategies of each player being how many doses they contribute (E.g., 1 dose, 2 doses, 3 doses, 4 doses...). Fill in the payoffs to the strategic grid. How much road repair will be purchased? Use the concept of Nash equilibrium to make this prediction. Is the equilibrium efcient? Briey explain why or why not
