9. Maximizing Profit in Pure Competition Profit maximum occurs When total revenue exceeds total costs by the greatest amount This occurs where the slopes of total cost and total revenue are equal

10. Chapter 23 Table 23.4

11. Profit Maximum in Perfect Competition Equivalent to finding equal slopes for TR & TC MR = MC For a firm in a perfectly competitive market MR = P therefore MR = P = MC

13. Short-run v. Long-run Economic Profit Firms maximize short-run economic profit In the long run, existence of short-run profits attract new market entrants, i.e., more competitors driving down prices ensuring zero long-run economic profit

31. Efficiency and Pure Competition Productive Efficiency P = Min ATC Allocative Efficiency P = MC Underallocation implied by P > MC Overallocation implied by P < MC

32. Consumer Surplus Perfect Competition Divides Surplus Value (Subjective) more or less equally between Consumers and Producers Provides Maximum Consumer Surplus consistent with keeping the good in production
