Study Notes
Monopoly Characteristics
- A monopoly market has one seller and many buyers.
- The product has no close substitutes.
- Significant barriers prevent new entrants.
- Barriers include scarce input resources, economies of scale, government support (e.g., patents, licenses), and strategic size advantages.
Monopoly vs. Perfect Competition
- Monopoly: Price maker, faces a downward-sloping demand curve.
- Perfect Competition: Price taker, faces a horizontal demand curve.
Market Power and Demand Curve
- Monopolies face the entire market demand curve.
- The key tradeoff is between quantity effect (higher output raises revenue) and price effect (lower price reduces revenue from all units sold).
Marginal Revenue and Demand
- Marginal revenue (MR) is always less than price (P) for a monopolist.
- MR = 0 when demand is unit elastic.
Monopoly Pricing Rule
- To find optimal quantity, use MR = MC.
- Find the corresponding price using the demand curve.
Monopoly Profit
- Profit = (P – ATC) * Q (difference between total revenue and total cost)
Deadweight Loss of Monopoly
- Monopolies produce less than the socially efficient quantity.
- This results in allocative inefficiency (deadweight loss).
Price Discrimination
- Price discrimination is charging different prices to different customers.
- Types include:
- First-degree (perfect price discrimination)
- Third-degree (group-based pricing, e.g., student discounts)
Natural Monopoly
- Economies of scale lead to a single firm being more efficient.
- Examples include utilities (water, electricity).
Regulation of Monopolies
- Governments regulate monopolies to improve welfare.
- Methods include price caps and antitrust laws.
- Challenges include distorted incentives and complex enforcement.
Quick Quiz 1: Monopoly Demand
- Given a demand curve (P = 50 – 2Q), derive total revenue (TR) and marginal revenue (MR) equations.
- Determine the quantity at which MR = 0.
Quick Quiz 2: Profit Maximization
- Given a cost function (TC = 100 + 5Q) and a demand curve (P = 60 – Q):
- Find the profit-maximizing price and quantity.
- Calculate the monopolist's profit.
Recap of Key Concepts
- Monopoly characteristics
- Price and quantity setting by monopolies
- Welfare implications
- Types of price discrimination

Discussion Questions
- Can monopolies ever be beneficial to society? Why or why not?
- What industries are examples of natural monopolies? Discuss their regulation?
Wrap-Up and Questions
- Monopolies maximize profit where MR = MC.
- Deadweight loss arises from reduced output.
- Price discrimination can potentially improve outcomes under certain conditions.
