- Game theory provides a framework to model and analyze strategic interactions between firms in an industry
- Firms are players in a "game" who make decisions that impact each other's outcomes (, price wars)
- Each firm's optimal strategy depends on the expected actions of competitors
- Key game theory concepts applied to industry analysis include:
- Nash equilibrium: A set of strategies where no firm can improve its payoff by unilaterally changing its strategy (low price equilibrium in competitive markets)
- : A strategy that yields the highest payoff for a firm regardless of competitors' actions (, cost leadership)
- Prisoner's dilemma: A situation where individually rational strategies lead to a suboptimal outcome for all firms (price wars, overproduction)
- Game-theoretic models help predict market outcomes and competitor behavior
- : Firms simultaneously choose output levels, assuming rivals will maintain their current output (oil and gas, commodity markets)
- : Firms simultaneously set prices, assuming rivals will maintain their current prices (retail, e-commerce)
- Stackelberg model: One firm (the leader) moves first, followed by other firms (the followers) who react to the leader's decision (technology markets, first-mover advantage)
Factors in competitive intensity
- Industry concentration and number of competitors
- Higher concentration (fewer firms) generally leads to less intense competition (oligopolies, monopolies)
- (HHI) measures market concentration: , where is the market share of firm
- and exit
- High barriers to entry reduce the threat of new entrants and decrease competition (economies of scale, patents, regulatory hurdles)
- High can intensify competition as firms are forced to remain in the market (asset specificity, long-term contracts)
- Product differentiation and
- Greater product differentiation reduces the intensity of competition as firms target different customer segments (luxury goods, niche markets)
- High switching costs for customers decrease their bargaining power and reduce competition (software ecosystems, loyalty programs)
- and buyers
- Powerful suppliers can squeeze industry profits by raising input prices (rare earth metals, specialized components)
- Powerful buyers can demand lower prices or better terms, reducing industry profitability (large retailers, government contracts)
Industry changes and strategic decisions
- can alter the basis of competition and shift bargaining power
- Online streaming (Netflix) disrupted the traditional video rental industry (Blockbuster)
- Mergers and acquisitions change industry concentration and competitive dynamics
- (merging with a competitor) increases market power but may face regulatory scrutiny (telecom mergers)
- (merging with a supplier or distributor) can reduce costs and improve coordination but may reduce flexibility (oil and gas, technology firms)
- Changes in regulations or government policies can create opportunities or threats
- of the airline industry increased competition and lowered prices
- Environmental regulations can increase costs for polluting industries (coal, chemicals)
- Shifts in consumer preferences and demand can impact the relative bargaining power of firms
- Increasing demand for eco-friendly products has pressured firms to adopt sustainable practices (electric vehicles, organic food)
Game theory for competitor predictions
- and accommodation strategies
- Incumbent firms may try to deter entry by signaling commitment to aggressive competition (limit pricing, capacity expansion)
- Alternatively, incumbents may accommodate entry and aim to differentiate their products or focus on different market segments (pharmaceuticals, consumer goods)
- Pricing and output decisions in oligopolistic markets
- Cournot model predicts that firms will produce more than the joint-profit maximizing output due to competitive pressures (airlines, steel)
- Bertrand model suggests that firms will set prices equal to marginal cost if products are perfect substitutes, leading to zero economic profits (commodity markets)
- and
- Firms may engage in explicit or tacit collusion to maintain high prices and profits (OPEC, price-fixing scandals)
- Game theory shows that collusion is difficult to sustain due to the incentive to cheat and undercut rivals
- Factors facilitating collusion include: few firms, high entry barriers, similar cost structures, and repeated interactions
- Strategic commitments and
- Firms can use irreversible investments to credibly commit to a course of action and influence competitors' behavior (capacity expansion, exclusive contracts)
- Credible threats can deter rivals from undercutting prices or entering a market (price matching guarantees, predatory pricing)
Key Terms to Review (24)
Accommodating Entry: Accommodating entry refers to a strategy used by existing firms in a market to allow new competitors to enter without significantly altering their own market position or pricing. This approach can stabilize the market and reduce potential price wars, as established firms may accept lower profit margins in the short term to maintain overall industry equilibrium. By accommodating new entrants, firms can foster a competitive environment that encourages innovation and consumer choice while also protecting their long-term interests.
Bargaining Power of Buyers: The bargaining power of buyers refers to the ability of customers to influence the price and terms of purchase from suppliers. This power can significantly impact competitive dynamics within an industry, as strong buyer power can force companies to lower prices, improve quality, or enhance service offerings in order to retain their customer base. The interplay between buyer power and supplier pricing strategies is crucial for understanding market dynamics and the overall competitive landscape.
Bargaining Power of Suppliers: Bargaining power of suppliers refers to the ability of suppliers to influence the price and terms of supply for goods and services. This power can impact profitability and competitive dynamics within an industry, as strong suppliers can drive costs up and dictate favorable conditions for themselves. Understanding this concept is vital for assessing competitive analysis and industry dynamics, as it highlights the relationships and power struggles between businesses and their suppliers.
Barriers to entry: Barriers to entry are obstacles that make it difficult for new competitors to enter a market or industry. These barriers can take various forms, such as high startup costs, strict regulations, strong brand loyalty among existing customers, and economies of scale that favor established firms. Understanding these barriers is crucial for analyzing market dynamics and the competitive landscape.
Barriers to exit: Barriers to exit are obstacles that make it difficult for a company to leave a market or industry. These barriers can be financial, legal, or strategic in nature, and they often influence a firm's decision-making process when considering whether to remain or exit a market. Understanding these barriers helps in analyzing competitive dynamics and industry behavior.
Bertrand Model: The Bertrand Model is an economic model of competition between firms that produce identical products and set prices simultaneously. In this model, firms compete by undercutting each other's prices, leading to a situation where the price of the good converges to marginal cost, which can result in zero economic profits for the firms involved. This behavior is crucial in understanding how price competition influences market dynamics, innovation strategies, and capacity decisions within an industry.
Cartels: Cartels are formal agreements among competing firms in an industry to coordinate their actions, typically to control prices, limit production, or share markets. These arrangements can significantly affect market dynamics, as they seek to maximize collective profits at the expense of competition. By forming a cartel, firms can stabilize their market positions and deter new entrants, which can lead to higher prices and reduced consumer choice.
Collusion: Collusion refers to an agreement between competing parties to work together in a way that is intended to limit competition, often leading to higher prices or reduced output. This cooperative behavior can emerge in various business contexts, influencing strategic decision-making, affecting relationships in repeated interactions, and impacting competitive dynamics within industries. When firms collude, they often prioritize collective benefits over individual gain, which can be seen in auction settings and experimental scenarios.
Cournot Model: The Cournot Model is an economic theory that describes an oligopoly market structure where firms compete in quantities rather than prices. In this model, each firm decides how much to produce based on the expected output of its competitors, leading to a Nash equilibrium where no firm has an incentive to change its output unilaterally. This model highlights the strategic interdependence among firms and is essential for understanding innovation, competition dynamics, and capacity decisions in oligopolistic markets.
Credible Threats: Credible threats refer to potential actions or strategies that a player in a game can take to influence the behavior of other players, which are believable and likely to be executed. These threats can serve as a strategic tool in negotiations, helping to deter unwanted actions from opponents or encourage compliance with desired behaviors. The effectiveness of credible threats relies on the player's ability to commit to the action, making it more likely that others will take them seriously in their decision-making processes.
Deregulation: Deregulation refers to the process of reducing or eliminating government rules and restrictions on an industry, allowing for greater competition and efficiency. This shift can lead to more innovation and lower prices for consumers, as businesses have more freedom to operate without regulatory constraints. However, it can also result in risks, including market failures and reduced protections for consumers.
Disruptive Innovations: Disruptive innovations are new technologies or business models that significantly alter the way industries operate, often displacing established market leaders and products. They typically start by targeting overlooked segments of the market and gradually improve to the point where they can challenge incumbents, reshaping competitive dynamics and industry structures in the process.
Dominant strategy: A dominant strategy is a strategy that yields a higher payoff for a player, regardless of what the other players choose. This concept is central to understanding decision-making in strategic interactions, where players assess their options based on the potential responses of others, leading to predictable outcomes in competitive environments.
Entry Deterrence: Entry deterrence refers to strategies used by existing firms in a market to prevent potential competitors from entering the market. This often involves creating barriers that make entry less attractive or more difficult for new entrants, such as pricing strategies, product differentiation, and capital investment. The effectiveness of these strategies often hinges on credible threats made by existing firms to maintain their market position and discourage new competition.
Herfindahl-Hirschman Index: The Herfindahl-Hirschman Index (HHI) is a measure of market concentration, calculated by summing the squares of the market shares of all firms in an industry. A higher HHI indicates a more concentrated market, which often suggests less competition and potentially greater market power held by fewer firms. Understanding HHI is crucial for assessing competitive dynamics and making informed business decisions regarding market entry or mergers.
Horizontal integration: Horizontal integration is a business strategy where a company acquires or merges with its competitors to increase market share and reduce competition. This strategy can lead to economies of scale, increased pricing power, and enhanced control over the market. By consolidating operations, firms aim to streamline their processes and strengthen their competitive position within the industry.
Monopoly: A monopoly is a market structure where a single seller or producer controls the entire supply of a product or service, giving them significant power over pricing and output. In this situation, the monopolist faces no direct competition, which allows them to dictate market conditions, often leading to higher prices and reduced consumer choice.
Nash Equilibrium: Nash Equilibrium is a concept in game theory where players, knowing the strategies of their opponents, choose their optimal strategies resulting in a situation where no player has anything to gain by changing their own strategy unilaterally. This balance occurs when each player's strategy is the best response to the strategies chosen by others, highlighting the interdependence of player decisions and strategic decision-making.
Oligopoly: An oligopoly is a market structure characterized by a small number of firms that dominate the market, where each firm is aware of the actions of the others. This interconnectedness leads to strategic decision-making, as the choices of one firm can significantly impact the others, resulting in various competitive behaviors and outcomes.
Prisoner's dilemma: The prisoner's dilemma is a fundamental concept in game theory that illustrates how two rational individuals may not cooperate, even if it appears that it is in their best interest to do so. This situation arises when both players have a choice to either cooperate or betray each other, leading to outcomes where mutual betrayal results in a worse payoff than if both had chosen to cooperate. Understanding this concept is crucial in various strategic decision-making scenarios, as it highlights the tension between individual rationality and collective benefit.
Product Differentiation: Product differentiation refers to the process of distinguishing a product or service from others in the market to make it more appealing to a specific target audience. This can involve various strategies like altering product features, enhancing quality, or improving customer service. It plays a crucial role in enabling firms to charge different prices and attract diverse customer segments.
Strategic commitments: Strategic commitments refer to long-term, often irreversible decisions made by firms to influence their competitive position in the market. These commitments can include investments in capacity, technology, or branding, and they signal a firm's intentions to competitors and customers. By making these commitments, firms can shape industry dynamics and create barriers to entry for potential rivals, ultimately impacting competition and market behavior.
Switching Costs: Switching costs refer to the expenses or inconveniences that a consumer faces when changing from one product or service to another. These costs can include financial costs, time investment, emotional factors, and the loss of benefits associated with the current choice. High switching costs can create a barrier for customers to switch to competitors, thus impacting competitive dynamics within an industry.
Vertical integration: Vertical integration is a strategy where a company expands its business operations into different stages of production within the same industry. This can involve either acquiring or merging with suppliers (backward integration) or distributors (forward integration), allowing firms to control more of the supply chain. By doing this, businesses aim to increase efficiency, reduce costs, and enhance their competitive advantage in the market.
