All Flashcards
Analyze the kinked demand curve for an oligopoly.
The demand curve is more elastic above the current price (competitors don't match price increases) and more inelastic below the current price (competitors match price decreases).
What is the definition of an oligopoly?
A market structure dominated by a few large firms with high barriers to entry.
What is a colluding oligopoly (cartel)?
Firms communicate and act as a single entity to control prices and output.
What is a non-colluding oligopoly?
Firms compete and do not cooperate, often practicing price leadership.
What is game theory?
The study of how people behave in strategic situations.
What is a 'game' in game theory?
Any situation where the outcome depends on the actions of two or more decision-makers.
What is a payoff matrix?
A table that shows the actions of two firms and the payoffs (usually profit) for each combination of choices.
What is a dominant strategy?
The best strategy for a firm, regardless of what the other firm does.
What is Nash Equilibrium?
A stable state where no player can unilaterally improve their position.
What is price leadership?
When the dominant firm initiates a price change, and other firms either follow or ignore.
What is a kinked demand curve?
A demand curve that is more elastic for price increases and more inelastic for price decreases.
What is the impact of antitrust laws on colluding oligopolies?
Antitrust laws aim to prevent collusion and promote competition, leading to lower prices and increased output.
How does government regulation affect pricing strategies in oligopolies?
Regulation can limit the ability of firms to set prices above competitive levels, protecting consumers from exploitation.
What is the effect of deregulation on competition in oligopolistic industries?
Deregulation can increase competition by allowing new firms to enter the market, but it can also lead to consolidation and increased market power for existing firms.
How does the enforcement of intellectual property rights affect innovation in oligopolies?
Strong intellectual property rights can incentivize firms to invest in research and development, leading to new products and technologies.
What is the impact of subsidies on the output levels of firms in an oligopoly?
Subsidies can encourage firms to increase production, potentially leading to lower prices and increased consumer welfare, but also potential inefficiencies.
How do import tariffs affect domestic oligopolies?
Tariffs can protect domestic firms from foreign competition, allowing them to maintain higher prices and market share, but also reducing consumer choice.
What is the effect of price ceilings on the supply of goods in an oligopoly?
Price ceilings can lead to shortages if set below the equilibrium price, as firms may reduce production due to lower profitability.
How can government intervention address inefficiencies in unregulated oligopolies?
Intervention can promote competition, prevent collusion, and ensure that prices reflect marginal costs, leading to greater economic efficiency.
