A monopoly is a situation of legal privilege or market failure, in which there is a producer or economic agent (monopolist) that has a great market power and is the only one in a given industry that has a product, good, resource or service determined and differentiated. The monopolist controls the quantity of production and the price, although not simultaneously, since the choice of production or price determines the position one has regarding the other; that is to say, the monopoly could first determine the production rate that maximizes its profits and then determine, by using the demand curve, the maximum price that can be charged to sell said production.
