Monopoly and Price Discrimination Concepts

Monopoly and Price Discrimination

• Profit-maximizing output and price (monopolist): A monopolist's profit-maximizing price isn't based on marginal cost (MC) but on where marginal revenue (MR) equals MC. Price is above marginal cost.

• Barriers to entry and monopoly: High barriers to entry allow monopolies to maintain economic profits in the long run.

• Monopolist vs. competitive industry: A monopolist charges a higher price and produces less output than a comparable perfectly competitive industry.

• Profit-Maximizing Output and Price

  • A monopolist produces a specific quantity (Q) and sells at a particular price (P).
  • The precise Q and P values depend on the specific market conditions.

• Monopolist's profit: Monopolist profit is the difference between the price they charge and the average total cost (AC), multiplied by the quantity produced

• Competitive market transition: If a monopoly becomes competitive, the quantity produced will increase to the competitive level and the price will fall to the competitive price.

• Monopolist's price per unit: A specific price is the profit-maximizing price, which depends on the marginal revenue and marginal cost of producing said output.

• Monopoly in the long run: In a monopoly, economic profits aren't eliminated by new firms entering the market in the short or long term. Instead, barriers to entry prevent this

• Profit Maximization point (N): Point N where Marginal Revenue(MR) is below 0 and Marginal Cost (MC) is above 0 is never profit-maximizing

• Perfectly competitive vs. monopoly output: Perfectly competitive markets efficiently allocate resources, producing an output level equal to the point where price equals marginal cost (P = MC); while monopolies produce less output at a higher price.

• Public policy toward monopolies: US policies regulate natural monopolies that exist in markets needing one provider for efficiency (e.g., utility companies).

• Price discrimination: The act of selling the same product to different consumers for different prices. The cost of providing the service is the same in those cases.

• Requirements for price discrimination: For price discrimination, the market structure must allow a firm to raise prices on sections of consumers who are not responsive to price changes. This is not possible in perfect competition.

• Effects of price discrimination on profit: A price-discriminating firm earns a larger profit than a firm that charges the same price to all consumers.

• Price discrimination definition: Price discrimination is charging different prices to different consumers for the same good or service.

• Price discrimination applicability: Price discrimination often occurs in monopolies and oligopolies where firms have some pricing power.

• Price discrimination and perfect competition: Price discrimination is not possible in perfect competition, since all firms are price takers. They must take the market price.
