Final answer:
Barriers to entry act as a 'wall' around a firm's market position, preventing new competitors from entering and maintaining market dominance. Examples include economies of scale, legal protections, and strategic practices like predatory pricing.
Step-by-step explanation:
The 'wall' that a firm builds around its position in a market is metaphorically referred to as barriers to entry. These barriers include numerous strategies and market conditions that prevent or discourage new competitors from entering an existing market and challenging incumbent firms. Barriers to entry help a firm maintain a monopoly or dominant position by protecting its market share and pricing power.
Examples of barriers to entry include economies of scale, which can lead to a natural monopoly where a single firm can supply the market more cheaply than any potential rivals. Other barriers involve the control of essential physical resources, legal restrictions such as patents, copyrights, or trademarks, and strategic practices like predatory pricing. This concept is crucial to understanding market structures and the behavior of firms within different competitive landscapes.
In oligopolistic markets, similar to the example of French detergent makers, firms may collude to 'cozy up' with each other, establish complex pricing structures, and effectively create barriers to keep competition at bay. However, such collusion often leads to tenuous relationships and can result in market instabilities like price wars. Ultimately, these barriers to entry shape the dynamics of competition and influence the strategic decisions made by firms.
