Monopoly and Market Power
Monopoly and market power refer to a market situation where a single firm dominates the entire market for a particular good or service. This dominance allows the firm to set prices and control supply without significant competition. As a result, monopolies can restrict output, raise prices, and reduce consumer choice, often leading to inefficiencies in the market. Market power is the ability of a firm to influence the terms and conditions of exchange within a market.

❓ Frequently Asked Questions
What is a monopoly?
A market in which a single firm dominates the entire market for a good or service, faces few or no close substitutes, and can set prices and control output.
What is market power?
The ability of a firm to influence prices or the quantity sold because competition is limited—often due to fewer firms, barriers to entry, or a unique product.
How does monopoly differ from perfect competition?
In perfect competition many firms sell identical products and no single firm can influence price; in a monopoly one firm dominates, acts as a price maker, and can restrict output.
Why do monopolies raise prices and restrict output?
Because with limited competition, the monopolist can set higher prices and produce less than the competitive level to maximize profit, leading to higher consumer prices and reduced welfare.
How can governments address monopoly power?
Through antitrust laws, regulation of prices or behavior, promoting competition, allowing entry for new firms, or, in some cases, public ownership of certain industries.
