People visit national parks because they want to experience the magnificence of nature in its unaltered primordial state. The problem is that the more people that come for this experience, the less unaltered nature there is. Suppose that there are N visitors to Yosemite National Park per day. Suppose also that the average consumer surplus (or utility) of a visit to the park per visitor in S is given by U(N,P) = 400 – (N/200) – P, where P is the price of admission. Assume that people will choose to visit the park as long as they have non-negative utility for the visit. Suppose also that the marginal cost (to the park) per visitor is 0, and that the park has no fixed costs. a. What is the demand function for visits to the park? b. Since U(N,P) is the average utility (or average consumer surplus) per visitor, when there are N visitors, what is the equation for Us(N,P), the total value of visitor (consumer) surplus for N visitors to the park in a given day with the price of admission to the park equal to P? c. In terms of P, what is the value of N that maximizes total visitor surplus? This will be an expression similar to N = A + (or -) bP, with actual numbers in place of A and b. How many visitors per day would maximize that surplus if admission were free (P-0)? How many people would actually visit the park (use the demand you calculated from part a) per day if admission were free? 1.

1.
People visit national parks because they want to experience the magnificence
of nature in its unaltered primordial state. The problem is that the more people that come
for this experience, the less unaltered nature there is. Suppose that there are N visitors to
Yosemite National Park per day. Suppose also that the average consumer surplus (or
utility) of a visit to the park per visitor in $ is given by U(N,P) = 400 – (N/200) - P,
where P is the price of admission. Assume that people will choose to visit the park as
long as they have non-negative utility for the visit. Suppose also that the marginal cost (to
the park) per visitor is 0, and that the park has no fixed costs.
a. What is the demand function for visits to the park?
b. Since U(N,P) is the average utility (or average consumer surplus) per visitor,
when there are N visitors, what is the equation for Us(N,P), the total value of
visitor (consumer) surplus for N visitors to the park in a given day with the price
of admission to the park equal to P?
c. In terms of P, what is the value of N that maximizes total visitor surplus? This
will be an expression similar to N = A + (or -) bP, with actual numbers in place of
A and b. How many visitors per day would maximize that surplus if admission
were free (P-0)? How many people would actually visit the park (use the demand
you calculated from part a) per day if admission were free?
