A monopoly is a market in which one person or company is the only supplier of a particular good or service. A monopoly is characterized by a lack of economic competition to produce a particular thing, a lack of viable substitute goods, and the possibility of a high monopoly price well above the seller's marginal cost that leads to a high monopoly profit. (Wikipedia. 2025. Monopoly https://en.wikipedia.org/wiki/Monopoly)
