Single-Price Monopoly:
Consider a single-price monopolist (i.e. the monopolist cannot price discriminate) facing the following market demand curve:
P = 120 − Q.
The monopolist has constant marginal cost of $20 and zero fixed cost.
(a) Determine the monopolist’s profit maximizing quantity, denoted QM, and profit-maximizing price, denoted PM. (b) Determine the quantity and price that would result in the market if this instead were a competitive market, denoted QC and PC, respectively. (c) Draw a picture of the market demand and marginal cost curves. Label the intercepts of the two curves, the monopoly outcome, and the competitive outcome. Determine the dead-weight loss resulting from market power.
