Because of the huge fixed cost of running pipes to everyone's home, natural gas is a natural monopoly. Suppose demand is Q = 100 - P and marginal revenue is MR = 100 - 2Q. Suppose marginal cost is $20, and the fixed cost of setting up the natural gas pipelines is $1000.

b. what regulatory price maximises social welfare? Compute the industry outcome (quantity, profit, consumer surplus, and social welfare) under this price. Would the policy be sustainable in the long run?
