Part 1 of 7 — Single Sellers and Market Power

What Creates a Monopoly?

A monopoly is a market with a single seller and high barriers to entry:

How Monopolies Differ from Competitive Firms

Why Is MR < P for a Monopolist?

To sell one more unit, the monopolist must lower the price on all units:

MR falls twice as fast as the demand curve (for a linear demand).

The Monopoly Graph

The monopolist maximizes profit in 3 steps:

1. Find quantity: Where MR = MC → this is Q*
2. Find price: Go UP to the demand curve at Q* → this is P*
3. Calculate profit: Profit = (P* − ATC) × Q*

Deadweight Loss

The monopolist produces where MR = MC, but charges P > MC:

• Competitive output would be where D = MC (higher Q, lower P)
• The triangle between competitive Q and monopoly Q is deadweight loss
• Monopoly transfers some consumer surplus to producer surplus and destroys the rest

Key Inefficiencies

Applied Recall ✍️

1. A monopolist maximizes profit by producing where MR = _______.

2. For a linear demand curve, the MR curve has _______ the slope of the demand curve. (half/twice)

3. Monopoly creates deadweight loss because P > _______.

Monopoly vs. Competition 🔍

Natural Monopoly & Regulation

A natural monopoly exists when one firm can serve the entire market at lower cost than multiple firms — ATC is still declining at market demand.

Regulatory Options

⚠️ AP Trap: Setting P = MC for a natural monopoly eliminates deadweight loss BUT requires a government subsidy because the firm operates at a loss (MC < ATC when ATC is declining).

Most regulated monopolies use fair-return pricing (P = ATC) as a compromise.
