Definition of Game Theory
Game Theory is a mathematical framework for analyzing situations in which the outcomes depend on the actions of multiple agents (referred to as “players”). Essentially, it’s the study of how individuals or entities make decisions that lead to outcomes based on the choices of others. Think of it as a strategic chess game played in real-life scenarios where each player’s choice directly affects the others, with potential for both cooperation and competition.
Game Theory vs. Traditional Economics
| Aspect | Game Theory | Traditional Economics |
|---|---|---|
| Focus | Strategic interactions among players | Market behaviors of consumers and producers |
| Decision Making | Vocabulary of strategy and scenarios | Supply and demand principles |
| Outcomes | Dynamic, depend on other players’ actions | Generally static, based on aggregate variables |
| Key Concepts | Nash Equilibrium, Dominant Strategies | Equilibrium, Price Setting |

Nash Equilibrium: A situation in a game where no player can benefit by changing their strategy while the other players keep theirs unchanged. In layman’s terms, everyone’s stuck in their decision-so no one (except maybe your spouse) wants to change their mind!
-
Prisoner’s Dilemma: A classic scenario where two individuals may not cooperate even if it appears that it is in their best interest to do so. It’s like deciding whether to share ice cream—who’s going to dip their spoon in first?!
