Duopoly Coordination and Economic Impact

The video explores why duopolies might coordinate to restrict quantity, despite the potential illegality. It explains the cost structures of identical firms in a duopoly and how they can act like a monopoly by coordinating. The video also discusses the incentives for firms to cheat on agreements, leading to changes in economic profit. It uses cost curves and market demand to illustrate these concepts.

Why might two companies in a duopoly consider coordinating their production?

• To restrict quantity and increase profits

• To reduce legal risks

• To diversify their products

• To increase competition

What is a characteristic of the cost structure for identical firms in a duopoly?

• Unique production technologies

• Different marginal cost curves

• Varying fixed costs

• Identical average total cost curves

How is the market marginal cost curve derived in a duopoly?

• By subtracting one curve from the other

• By averaging the individual cost curves

• By doubling the individual cost curve horizontally

• By adding the curves vertically

What happens to the market demand curve when two firms coordinate like a monopoly?

• It shifts to the right

• It becomes steeper

• It remains unchanged

• It becomes flatter

In a coordinated duopoly acting like a monopoly, where is the optimal quantity determined?

• Where average cost equals average revenue

• Where fixed cost equals variable cost

• Where marginal cost equals marginal revenue

• Where total cost equals total revenue

What is the total economic profit if two firms in a duopoly coordinate perfectly?

• 250

• 500

• 750

• 1000

Why might a firm in a duopoly decide to cheat on a coordination agreement?

• To reduce production costs

• To comply with legal regulations

• To increase its market share

• To gain a higher economic profit

What is the impact on total economic profit when one firm in a duopoly cheats?

• It doubles

• It decreases

• It remains the same

• It increases

How much economic profit does the cheating firm make when it increases production?

• 280

• 250

• 200

• 300

What is the consequence for the non-cheating firm when the other firm cheats?

• It benefits from increased prices

• It gains more profit

• It loses market share

• It receives less economic profit
