Study Notes

Monopoly Behavior

  • Monopoly firms have market power to set prices above marginal cost.
  • Price discrimination is a strategy to maximize revenue by charging different groups of customers different prices.
  • First-degree price discrimination involves charging each consumer their maximum willingness to pay.
  • Second-degree price discrimination involves charging different prices based on the quantity consumed.
  • Third-degree price discrimination involves dividing consumers into groups and charging different prices to each group.
  • Examples of price discrimination include: segmented pricing, intertemporal price discrimination, peak-load pricing, and two-part pricing.

Capturing Consumer Surplus

  • A firm can capture consumer surplus by charging different prices to customers with different willingness to pay.
  • Ideally, a firm would charge a higher price to consumers willing to pay more than the market price.
  • A firm can capture consumer surplus in two ways. By charging a higher price to willing consumers, while not lowering the price for other customers. By selling to customers willing to pay a lower price, while not lowering the price for other customers.

Intertemporal Price Discrimination

  • Demand for certain goods can change over time or be seasonal.
  • Monopolies can adjust their prices to accommodate these changes in demand.
  • This is known as intertemporal price discrimination.

Peak-Load Pricing

  • Demand for some goods can increase rapidly during certain periods.
  • Marginal costs typically increase during peak times.
  • A monopoly will often increase prices during peak times to maximize profits.

Two-Part Pricing

  • Some services are priced in two parts: an entry fee and a usage fee.
  • The goal is often to capture the entire consumer surplus.
  • For multiple consumer groups, the monopoly sets prices to maximize its profit and captures more of the surplus.
