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.
