Which market structure often leads to a lack of competition?

In the context of market structures, a monopoly occurs when a single company or entity dominates an entire market, serving as the sole provider of a particular good or service. This dominance typically arises due to high barriers to entry, which can include substantial capital requirements, control over a crucial resource, or regulatory advantages that prevent other competitors from entering the market.

As a result, a monopoly has significant pricing power, allowing the monopolist to set prices higher than they would be in a competitive market. This lack of competition often leads to reduced innovation, lower quality products, and fewer choices for consumers. Without competitors, there is little incentive for the monopolist to improve efficiency or to be responsive to consumer demands. Therefore, monopolies are frequently criticized for their potential to exploit consumers and stifle economic competition, which is why this market structure is associated with a lack of competition.

On the other hand, other market structures like perfect competition involve many firms competing against each other, which generally fosters innovation and improves consumer welfare. Oligopoly, while it has a few dominating firms, still presents some level of competition, and monopsony refers to a market structure with a single buyer, which does not directly pertain to supplier competition but rather to purchasing power dynamics.
