Monopoly, Features, Pricing under Monopoly

1. Introduction to Monopoly

A monopoly is a market structure where a single firm is the sole producer and seller of a product with no close substitutes. The monopolist has full control over pricing, making it a price maker rather than a price taker like in perfect competition.

Unlike perfect competition, in a monopoly:

• There is no competition,
• The firm has significant pricing power,
• High barriers prevent new firms from entering the market.

2. Features of Monopoly

(i) Single Seller

• One firm dominates the entire market.
• The firm and the industry are the same entity.

(ii) No Close Substitutes

• Consumers have no alternative products, making them dependent on the monopolist.
• Examples: Railways, patented drugs, and utility services.

(iii) High Barriers to Entry

• New firms cannot enter easily due to:
  • Legal restrictions (patents, government licenses).
  • High startup costs (large capital investment).
  • Exclusive ownership of essential resources.

(iv) Price Maker

• A monopoly firm decides its price instead of following market forces.
• However, higher prices reduce demand, so the firm must balance price and sales volume.

(v) Downward Sloping Demand Curve

• Unlike perfect competition where demand is perfectly elastic, monopoly demand slopes downward.
• The firm must lower the price to sell more units.

(vi) Abnormal Profits in the Long Run

• Due to entry barriers, monopolies can sustain long-term supernormal profits.
• No new firms enter to reduce profits.

3. Pricing Under Monopoly

How a Monopoly Sets Prices

• A monopolist does not have a fixed price like in perfect competition.
• It sets the price where marginal cost (MC) = marginal revenue (MR) but charges a price from the demand curve (AR curve), which is higher than MC.

Steps in Monopoly Pricing

1. Determine Demand (AR Curve) – The monopolist identifies how much consumers are willing to pay at different output levels.
2. Find Marginal Revenue (MR Curve) – Since the firm must reduce price to sell more, MR lies below AR.
3. Find Profit-Maximizing Output – The firm sets output where MR = MC.
4. Set the Price – From the equilibrium output, the firm charges the price from the AR curve.
5. Earn Supernormal Profits – Since the price is higher than MC, the monopolist earns high profits.

Price Determination in Monopoly

Explanation of the Monopoly Pricing Graph

The graph shows how a monopolist sets prices based on revenue and cost curves.

1. Average Revenue (AR) or Demand Curve (Blue Line)
   • Downward sloping, meaning the firm must lower the price to sell more.
   • Represents the price consumers are willing to pay at each output level.
2. Marginal Revenue (MR) Curve (Red Dashed Line)
   • Lies below the AR curve, since selling an extra unit reduces revenue from previous sales.
   • Declines faster than AR due to the price reduction effect.
3. Marginal Cost (MC) Curve (Green Line)
   • Upward sloping, representing increasing production costs.
4. Profit Maximization (Black Dot)
   • The monopolist chooses output where MR = MC (Q*).
   • The firm charges a price higher than MC by referring to the AR curve (P*).

Key Takeaways

✅ Monopolists are price makers, setting prices above MC.
✅ MR < AR, meaning revenue grows at a decreasing rate.
✅ Monopolies restrict output to maintain higher prices.
✅ Supernormal profits exist in the long run due to barriers to entry.

This pricing strategy allows monopolies to maximize profits while controlling supply
