π Introduction to Game Theory
Game Theory is all about strategic interactions. It analyzes situations where the outcome of your choice depends on what others choose to do. Think of it like a chess game β your moves affect your opponent, and vice versa.
π― Key Characteristics of Game Theory:
- π Interdependence: Each player's actions affect the outcomes for all other players.
- π€ Strategic Thinking: Players must anticipate the actions of others to make optimal decisions.
- π² Payoffs: Each outcome results in a specific payoff (benefit or cost) for each player.
π’ Introduction to Perfect Competition
Perfect Competition is a market structure where many firms sell identical products, and no single firm has the power to influence the market price. Itβs like a huge farmer's market where everyone is selling the same tomatoes.π
π Key Characteristics of Perfect Competition:
- π§βπΎ Many Buyers and Sellers: A large number of participants ensures no single entity can control the market.
- π¦ Homogeneous Products: All products are identical, making price the only differentiating factor.
- πͺ Free Entry and Exit: Firms can easily enter or leave the market.
- βΉοΈ Perfect Information: All buyers and sellers have complete information about prices and products.
