Is monopoly determined by market equilibrium?

No, monopoly is not determined by market equilibrium. A monopoly exists when a single firm dominates the market for a particular good or service, often due to barriers to entry that prevent other firms from competing. In contrast, market equilibrium occurs when supply equals demand, which can happen in both competitive and monopolistic markets. While a monopolist can influence prices and output, it does not operate under the same conditions as a competitive market seeking equilibrium.
