Just a few large firms are represented with each firm attempting to anticipate the strategy of its competition. It is moderate to high entry barriers for potential competitors. The final type of market structure is the monopolistic competition. It has no entry barriers. Like the perfect competition this structure has many firms competing in the market—but small in size—and no entry barriers. They differ in that the firms produce different products. In order to make sound decisions, it is important for managers to understand supply and demand, and how they affect price and output in competitive markets.
