Microeconomics (ECON 101) Game Theory Practice Problems: Oligopoly, Payoff Matrices, and Nash Equilibrium
University of California Berkeley
ECON 101 - Microeconomics | Practice Problems

Overview
A microeconomics problem set for strategic decisions, dominant strategies, Nash equilibrium, prisoner dilemma logic, repeated games, and oligopoly intuition.

Key topics
•payoff matrices and best responses
•dominant strategy vs Nash equilibrium
•prisoner dilemma and cooperation problems
•Cournot and Bertrand oligopoly intuition
•cartels, cheating incentives, and repeated games

Suggested study tasks
•solve 12 payoff matrix problems
•circle best responses and identify Nash equilibria
•compare dominant strategy and Nash equilibrium in short answers
•explain why cartels are unstable
•write a repeated-game cooperation checklist

Common pitfalls
•choosing the highest payoff without considering the other player
•confusing dominant strategy with Nash equilibrium
•forgetting each player chooses independently
•assuming collusion is always stable
•mixing monopoly pricing with oligopoly strategy
