Monopoly

A market structure where a single firm controls the entire supply of a product or service.

Monopoly Equilibrium

The point at which a monopolist's marginal revenue (MR) equals its marginal cost (MC), representing the optimal level of production for maximum profits.

Supernormal Profit

The difference between a monopolist's total revenue and total cost, usually represented by a shaded area on a graph and often higher than profits in other market structures.

Demand Curve

Describes the relationship between the price and quantity demanded for a good or service. A monopolist's demand curve is typically downward sloping, meaning they must lower the price to sell more.

Pricing Power

A monopolist's ability to set prices without direct competition, often resulting in higher prices and reduced consumer choice.

Short-Run Equilibrium

In the short-run, a monopolistically competitive firm can earn economic profits, losses, or break even, just like a monopolist. However, the firm's demand curve will be more elastic, reducing the potential for high profits.

Limitations of Monopolistic Competition

The model of monopolistic competition has several limitations, including the difficulty in defining the boundaries of the market, the potential for advertising to create artificial differences, and the assumption of perfect information for consumers.

Monopoly Price Discrimination

Monopoly price discrimination occurs when a monopolist charges different prices for the same product to different customers based on their willingness to pay. This is possible when the monopolist can segregate customers, prevent resale, and successfully estimate their willingness to pay.

Minimum Wage & Poverty

The minimum wage may not be sufficient to alleviate poverty, especially for families with many dependents. While a worker might be paid above minimum wage, the family's income may still be very low.

Inelastic Supply of Land

Land has a fixed supply in a given area, making it inelastic. This unique property makes land different from other factors of production.

Demand for Land

The demand for land is influenced by its marginal revenue product (MRP). Land owners can charge rent that equals the MRP. This MRP decreases as more land is used, as the law of diminishing returns takes effect.

Supply of Land

The supply of land is considered perfectly elastic from an individual land owner's perspective. But it's less than perfectly elastic from an industry point of view, as there's limited land in the entire market.
