    What is a monopoly?

    A market structure where a single firm controls the entire supply of a product, with no close substitutes.

    Where does a monopolist maximize profit?

    The point at which a monopolist produces the quantity that yields the maximum profit. This occurs when the extra revenue gained from selling one more unit (marginal revenue) equals the extra cost of producing that unit (marginal cost).

    What does the demand curve look like for a monopolist?

    A downward sloping curve that represents the relationship between the price a monopolist charges and the quantity demanded by consumers. Unlike a perfectly competitive firm, a monopolist faces the entire market demand curve.

    How does the price in a monopoly compare to marginal cost?

    In a monopoly, the price is always higher than the cost of producing one extra unit (marginal cost). This is because they can set the price as the single seller in the market.

    When does a monopolist maximize total revenue?

    A monopolist maximizes total revenue when the extra revenue gained from selling one more unit (marginal revenue) becomes zero. This implies that selling more units beyond this point will lead to a decrease in total revenue.

    What is the key difference between a monopolist's output decision and a perfectly competitive firm?

    In a monopoly, the firm produces at the output level where marginal revenue equals marginal cost, not where price equals marginal cost, which is the case under perfect competition. This is because they can control both price and quantity.

    What is the socially optimal price in a monopoly?

    For a monopolist, social efficiency is achieved when the price they charge is equal to the cost of producing one extra unit (marginal cost). This maximizes social welfare by balancing the benefits to buyers and the costs to the seller.

    What happens to the price when a monopolist increases output?

    If the monopolist increases output, the price will decrease because a linear demand curve implies that as quantity increases, price must decrease to maintain the same demand.

    Study Notes

    Monopoly Characteristics

    • A monopoly has a single seller.
    • There are no close substitutes for the product.
    • There is no free entry or exit in the market.
    • Consumers and producers have perfect information.

    Monopoly Profit Maximization

    • A monopolist maximizes profit where marginal cost equals marginal revenue.
    • Marginal cost is the extra cost of producing one more unit.
    • Marginal revenue is the extra revenue obtained from selling one more unit.

    Monopoly Demand Curve

    • The demand curve for a monopolist is downward sloping.
    • This means the monopolist can sell more units only by lowering the price.

    Monopoly Price and Cost

    • A monopoly's price is always higher than its marginal cost. This contrasts with perfect competition, where price equals marginal cost.
    • At the profit maximizing output, A monopolist will charges a price above marginal cost.

    Monopoly Output

    • The monopolist produces an output level where marginal revenue equals marginal cost
    • The monopolist will restrict output to maintain a high price, potentially resulting in lower output than would be socially optimal.

    Price Discrimination

    • First-degree price discrimination is when a monopolist charges each consumer the maximum price they are willing to pay.
    • In a regulated natural monopoly if the government sets the price equal to marginal cost, then the monopolist will likely experience losses.

    Calculation Questions/ Examples

    • Examples of calculation questions involving demand, cost, revenue, and profit maximization for a monopolist, are included
