5. Introduction to I.O. I.O. (Industrial Organization) is a study about Market structure/organization Relationship with Firms Behavior Methodology Structure Conduct Performance Game Theory What we study: Strategy Based Approach

6. Profit Maximization Firms Objective Profit Maximization Firms Optimal Choice MP(q) = MR(q) – MC(q) MR(q*) = MC(q*) If MR > MC, expands output If MC > MR, reduce output

7. Perfect Competition The 4 assumptions 1. Many Buyers and Sellers 2. Homogeneity of Output 3. Perfect Information 4. Free Entry or Exit 1 – 3 : Price Takers

8. From a Single Firm to Market Profit-Maximizing Choice p = MC(q*) Market Supply = sum of individual supply(p) Market Equilibrium Supply(p) = Demand(p)

9. Efficiency Measures of Gains from Trade Consumer Surplus Producer Surplus Total Surplus Pareto Optimality If it is not possible to make one person better off without making another worse off.
