Oberlin is looking to purchase farmland north of town and turn it into a protected bird sanctuary. Suppose each acre costs $1,000 to buy and protect. There are 500 people in Oberlin who value the bird sanctuary. They each have an inverse demand function of P=25− 2Q, where Q is the number of acres preserved and P is the price they are willing to pay to for Q acres of preserved land. a) In the efficient allocation, how large is the bird sanctuary? (2 pts.) P=25−26 b) What is the total surplus from the efficient allocation?
