The Coffee Shop Dilemma
Analyzing US Financial Fragility
Two competing coffee shops, 'The Daily Grind' and 'Espresso Yourself', are located across the street from each other. Each must independently decide whether to lower their prices. The table below shows the daily profit each shop can expect based on their combined decisions. The first number in each cell is the profit for The Daily Grind, and the second is for Espresso Yourself.
Espresso Yourself: Keep Price High Espresso Yourself: Lower Price The Daily Grind: Keep Price High $500, $500 $200, $600 The Daily Grind: Lower Price $600, $200 $300, $300 Assuming both shops act in their own immediate self-interest to maximize their own profit, what is the most likely outcome of this situation?
The Farmers' Irrigation Dilemma
A social interaction, where each individual's decisions affect the outcomes of others, will always result in a worse outcome for everyone involved when each person acts solely in their own self-interest.
A small city's transportation market for on-demand rides is dominated by a single taxi company that owns all the operating licenses, resulting in high prices and long wait times for consumers. A new city council wants to introduce policies to make this market more competitive. Arrange the following potential policy changes in order from the one that would MOST increase competition to the one that would LEAST increase competition.

Finding Best Responses
Dominant Strategy
Two competing firms, Firm A and Firm B, must simultaneously decide whether to 'Launch a new product' or 'Maintain the current product line'. The resulting profits for each firm depend on the actions of both, as shown in the following payoff structure, where the first number in the parentheses is Firm A's profit and the second is Firm B's profit:
- If both firms Launch: ($50 million, $50 million)
- If Firm A Launches and Firm B Maintains: ($120 million, $30 million)
- If Firm A Maintains and Firm B Launches: ($40 million, $100 million)
- If both firms Maintain: ($80 million, $80 million)
Given this information, if you know that Firm B has decided to 'Launch a new product', what is the best response for Firm A to maximize its own profit?
Two competing coffee shops, The Daily Grind and Brew & Co., are deciding on a daily promotion. The table below shows the daily profit (in dollars) for each shop based on the combination of strategies they choose. The first number in each pair is The Daily Grind's profit, and the second is Brew & Co.'s profit.
Payoff Matrix:
Brew & Co: Latte Discount Brew & Co: Muffin Combo Brew & Co: No Special Grind: Latte Discount ($100, $100) ($150, $80) ($160, $90) Grind: Muffin Combo ($110, $140) ($120, $120) ($200, $50) Grind: No Special ($80, $220) ($180, $180) ($140, $140) Match each of Brew & Co.'s potential strategies to The Daily Grind's best response to maximize its own profit.
Roommate Chore Dilemma
Farmer's Irrigation Choice
Two roommates, Alex and Ben, must decide independently whether to 'Clean' their shared apartment or 'Relax'. The satisfaction they each get from their decision depends on what the other person does, as shown in the payoff table below. The first number in each cell is Alex's satisfaction score, and the second is Ben's.
Ben: Clean Ben: Relax Alex: Clean (8, 8) (3, 10) Alex: Relax (10, 3) (0, 0) Statement: If Ben decides to 'Clean', Alex's best response is also to 'Clean'.

Consider the payoff matrix below, which shows the profits (in thousands of dollars) for two competing firms based on their advertising budget decisions. The first number in each cell is the profit for Innovate Corp, and the second is for Tech Solutions.
Tech Solutions: Increase Tech Solutions: Maintain Innovate Corp: Increase (60, 50) (____, 30) Innovate Corp: Maintain (40, 70) (80, 80) If Tech Solutions chooses to 'Maintain' its budget, what is the minimum whole number profit (in thousands of dollars) that must go in the blank to make 'Increase' the best response for Innovate Corp?
