Economics – Efficiency and market failure | e-Consult

A firm achieving and maintaining market dominance in a particular industry often benefits from a combination of economies of scale and barriers to entry. Economies of scale refer to the cost advantages that a firm can achieve as it increases its level of output. This can manifest in several ways. For example, a dominant firm may be able to spread fixed costs over a larger volume of production, resulting in lower average costs per unit. It may also benefit from specialized equipment and processes that are only cost-effective at high volumes. These lower costs provide a significant competitive advantage.

Barriers to entry are factors that make it difficult for new firms to enter the market and compete with the dominant firm. These barriers can be legal barriers, such as patents or licenses that give the dominant firm exclusive rights. Financial barriers, such as the high capital investment required to start a business in the industry, can also deter potential competitors. Natural barriers, such as control over essential resources or established brand loyalty, can make it difficult for new firms to gain a foothold. Economies of scale themselves can act as a barrier to entry; new firms may find it impossible to match the dominant firm's low costs without achieving a similar scale of production.

The combination of these factors creates a powerful advantage for the dominant firm. The economies of scale allow it to produce goods or services at a lower cost than any potential competitor, while the barriers to entry prevent new firms from challenging its position. This allows the dominant firm to maintain its market share and potentially exploit its market power to raise prices or restrict output. The OFT often targets firms with both significant economies of scale and high barriers to entry because this combination poses the greatest threat to competition.
