Profit-Maximizing Price in Monopoly
Profit-Maximizing Price in Monopoly
The monopolist will produce where marginal cost (MC) equals marginal revenue (MR). Price is then determined by the demand curve at that quantity. In this case, MR=5, so the profit-maximizing quantity is 15 (from demand equation). The corresponding price is then 20-15= $5.
Shutdown Point in Perfect Competition
Shutdown Point in Perfect Competition
If the market price falls below the minimum of the average variable cost (AVC) curve, the firm will shut down in the short run. This is because the firm is not covering its variable costs and is better off shutting down to minimize losses.
Monopolist's Marginal Revenue
Monopolist's Marginal Revenue
A monopolist's marginal revenue (MR) is always less than the price (P) due to the downward-sloping demand curve. This means that to sell one more unit, the monopolist must lower the price on all units sold, reducing revenue.

Study Notes
Monopoly and Perfect Competition Quiz
-
Profit Maximization (Monopolist): A monopolist maximizing profit produces where marginal cost equals marginal revenue. In the given example, the demand curve is (P = 20 - Q) and marginal cost is constant at $5. This leads to finding profit-maximizing price by understanding the marginal revenue curve.
-
Perfect Competition: Shutdown Point: If market price drops below average variable cost, the firm shuts down. This is because it can't even cover the variable costs.
-
Monopolist's Marginal Revenue: A downward-sloping demand curve means a monopolist's marginal revenue is always less than the price.
-
Price Discrimination: Price discrimination requires the ability to separate consumers with different price sensitivities and prevent resale.
-
Perfect Competition's Supply Curve: A perfectly competitive firm's short-run supply curve is the part of its marginal cost curve above the average variable cost curve.
-
Lerner Index: The Lerner Index quantifies market power by measuring the difference between price and marginal cost relative to price.
-
Reduction of Deadweight Loss: Allowing perfect price discrimination could reduce deadweight loss in a monopoly situation, as it increases the firm's ability to extract consumer surplus.
-
Calculating Marginal Revenue: If the demand curve is ( P = 50 - 2Q ), the marginal revenue is ( MR = 50 - 4Q ).
-
Perfect Competition Long-Run Equilibrium: In long-run equilibrium in perfect competition, price equals both marginal cost and average total cost
-
Natural Monopoly: A natural monopoly results from significant economies of scale that make it more efficient for one firm to supply the entire market. This is typically represented by a downward-sloping long-run average cost curve.
