Adams and Brash own lots A and B, respectively, of Section 210, bordering on State Route 11. The Adams lot (210A) is adjacent to the state road and the Brash lot (210B) is immediately behind it. Access to 210B is provided for in an easement under which the owner of 210A must allow free passage to occupants of all inned lots.

Adams already has a house on lot A and has resided there for five years. Upon construction of the house, Adams also caused a road to be prepared, running from Route 11 to the back border of his lot. The road is not hard-surfaced but is a type of "oiled gravel" surface common to private roads and driveways in rural areas. This kind of surface is subject to erosion and general deterioration over time. However, Pitts Gravel will come and provide any number of "doses" of road repair at a price of $25 per dose.

[The concept of a "dose" of an input is a pedagogical simplification that will be utilized a number of times below. It is used to collapse a heterogeneous, multidimensional package of possible adjustments to a single dimension. Hence "road repair" could be a mix of many different services in varying proportions, but no useful purpose is served by explicitly considering multidimensional adjustments. Through the simplification of road repaid into "dose" we can focus on a straightforward quantitative adjustment]

*Note: the cost of each individual dose is $25 (i.e., "marginal cost"), so 2 doses would cost in total $50, 3 doses cost $75, etc.

7. What if more people enter the scene, Cherkas, Donatella, Eglin, all with the same preferences as Adams and Brash. Is it any more likely the efficient solution will be reached with more people involved? What would be the likely outcome? Explain.

10.

Suppose Adams was the sole owner of the road and could charge Brash for use of the road. Would this lead to the efficient level of road repair? Explain.

Give answer with explaination thank you!
