Math Problem Statement
Suppose a monopolist faces a market demand curve given by P = 50 - 0.5*Q. Marginal cost is initially equal to zero and constant.
a. (4) Calculate the profit maximizing price and quantity. Use the Lerner index to calculate the price elasticity of demand at this point. What is the amount of deadweight loss associated with this monopoly?

Formulas
Demand Curve: P = 50 - 0.5Q
Total Revenue: TR = 50Q - 0.5Q^2
Marginal Revenue: MR = 50 - Q
Lerner Index: L = (P - MC) / P
Deadweight Loss: DWL = 1/2 * (Q_socially efficient - Q_monopoly) * (P_monopoly - P_socially efficient)
