Question

Suppose that the four firms in an oligopoly are getting together to collude. How might ease of entry into their industry affect how high they set their prices?

Short answer

The ease of entry into an industry directly affects the pricing strategy of colluding firms in an oligopoly. If the ease of entry is high, colluding firms will be cautious about setting their prices too high, because new firms may enter the market to take advantage of the high prices, thus increasing competition and forcing colluding firms to lower their prices. If the ease of entry is low, colluding firms can set their prices relatively higher without worrying about new competition.

Step-by-step solution

Understand the concepts of oligopoly and collusion

An oligopoly is a market structure characterized by a few large firms dominating the market, offering similar or differentiated products. In such a market, firms make strategic decisions based on the actions and reactions of their rival firms. Collusion occurs when companies in the same market cooperate to set prices, allocate market shares, or engage in other activities to maximize their joint profits. In our exercise, we are given a situation where the firms in an oligopoly are colluding to set their prices.

Identify the role of ease of entry

Ease of entry in an industry refers to how easily new firms can enter the market and compete with existing firms. The ease of entry can be influenced by factors like high capital requirements, legal barriers, economies of scale, and so on. When it is easy for new firms to enter the market, existing firms face more competition, making them adjust their pricing strategies accordingly.

Explain how ease of entry affects price-setting in case of collusion

In our given exercise, the four firms in the oligopoly are colluding to set their prices. If the industry has an ease of entry, it means that their collusion could be threatened by the entry of new firms in the market, which might not follow the colluding pricing strategy. When there is ease of entry, if the colluding firms set their prices too high, new firms may enter the market to take advantage of the high prices, thus increasing competition. This would force the colluding firms to lower their prices to maintain their market share. As a consequence, the colluding firms would be cautious about setting their prices extremely high, fearing the entry of new firms.

Understand the implications of ease of entry on collusion

If the ease of entry is low, colluding firms have less to worry about new competition. As a result, they can set their prices relatively higher, knowing that new firms will have a difficult time entering the market. However, if the ease of entry is high, colluding firms have to be more cautious in setting their prices to avoid encouraging new competition. They may also have to invest in non-price competition strategies, such as product differentiation, advertising, or innovation, to maintain their market share. In conclusion, the ease of entry into an industry directly affects the pricing strategy of colluding firms in an oligopoly. The easier it is for new firms to enter the market, the more cautious the colluding firms will be in setting their prices, as it increases competition and reduces their market share.

Key concepts

Market Structures

Understanding different market structures is fundamental in analyzing the behavior of firms and their price-setting abilities. An oligopoly, one of the primary market structures, involves a small number of firms that dominate the market. Due to the limited competition, these firms have significant market power, which allows them to influence prices. Other market structures include perfect competition, with many firms and no control over prices; monopoly, with a single provider dictating prices; and monopolistic competition, where many firms sell differentiated products and have some price control.

Each market structure presents unique characteristics that shape a firm's strategy regarding pricing, production, and marketing. For students grappling with these concepts, remember that the key difference lies in the number of competitors and the level of control a firm has over the market.

Ease of Market Entry

Ease of market entry refers to the challenges or barriers that new competitors may face when trying to establish themselves in a particular industry. These barriers can include high startup costs, stringent regulatory requirements, and brand loyalty that existing competitors already enjoy. In the context of an oligopoly, where collusion can impact price-setting, the ease with which new firms can enter the market can significantly hinder or reinforce the efficacy of such collusion.

Low barriers to entry can threaten the stability of a collusive agreement, as new entrants can undercut prices if they are not part of the collusion. On the other hand, high barriers protect the colluding firms, allowing them to maintain higher prices. This core concept teaches students how strategic business decisions are influenced by external market factors.

Price-Setting Strategies

Delving into price-setting strategies, we discover how firms decide on the most advantageous pricing for their products. In an oligopoly, due to the few players and the interdependent nature of the market, firms tend to be cautious. They might use strategies like price leadership, where one firm sets the price and others follow, or tacit collusion, where they implicitly agree not to compete on price.

In a collusive arrangement, firms can use joint price-setting to increase their profits above competitive levels. This approach, however, is illegal in many jurisdictions. It's important for students to recognize that these strategies, while potentially profitable, must be balanced with legal and ethical considerations.

Non-Price Competition

When we shift our focus towards non-price competition, we examine how firms can differentiate themselves through means other than price. This includes enhancing product quality, aggressive advertising, customer service improvements, and innovation. Particularly in an oligopoly, firms might opt for non-price competition when colluding to set prices, to avoid attracting new entrants that could disrupt the market balance.

By understanding non-price competition, students can appreciate the breadth of strategies a firm might employ to remain competitive. Offering unique value propositions can cement a firm's position in the market and create a loyal customer base without having to engage in price wars.
