Which marketplace feature is NOT typical of perfect competition?

High barriers to entry are not typical of perfect competition. In a perfectly competitive market, the conditions are characterized by ease of entry and exit for businesses. This ensures that many small firms can enter the market without significant obstacles, leading to a large number of competitors offering similar products.

The presence of many small businesses with identical products supports the idea that no single firm can influence the market price, which is purely determined by supply and demand. Additionally, if one supplier attempts to raise prices, consumers can easily switch to a competitor's identical product. The equal market share for all suppliers is also a characteristic of perfect competition, as competition drives prices down to the level where firms earn just enough to cover their costs, resulting in a balance among market participants.
