In a monopoly market structure, how does the quantity supplied affect deadweight loss when the monopolist maximizes profit?

In a monopoly market, a single seller controls the entire supply of a product, which allows them to set prices higher than in competitive markets. When a monopolist maximizes profit, they produce less quantity than what would be supplied in a competitive market. This reduced quantity leads to deadweight loss, which is the loss of economic efficiency that occurs when the quantity traded is less than the optimal level. For example, if a monopoly sells 100 units instead of the 150 units that would be sold in a competitive market, the lost transactions represent the deadweight loss, as some consumers who would have bought the product at a lower price are unable to do so. Thus, the monopolist's profit-maximizing behavior creates a gap between consumer demand and actual supply, resulting in fewer total benefits for society.
