Monopoly Revision Sheet

1. 📌 Essentials

  • Monopoly: one firm with no close substitutes, market power
  • Market share > 25% raises regulatory concern
  • Price setter: facing downward-sloping demand curve
  • Revenue: TR = P × Q; AR = P; MR always less than P
  • Profit maximization where MR = MC; set price from demand
  • Monopoly profit: (P − ATC) × Q
  • Deadweight loss results from underproduction
  • Price discrimination: charging different prices based on consumer willingness
  • Natural monopolies: lower costs due to economies of scale
  • Regulation often involves setting P = MC, risking losses
  • Anti-trust laws: prevent abuse of monopoly power
  • Market power stems from barriers, resource control, or government rights
  • Welfare impact: monopolies reduce consumer surplus, create deadweight loss

2. 🧩 Key Structures & Components

  • Demand curve — downward-sloping; determines P and Q
  • Total Revenue (TR) — P × Q
  • Average Revenue (AR) — TR / Q, equals demand curve
  • Marginal Revenue (MR) — ΔTR / ΔQ; always less than P for monopolies
  • Profit maximization point — MR = MC
  • Barriers to entry — resource control, legal rights, economies of scale
  • Price discrimination — selling to segments at different prices
  • Regulatory agencies — enforce competition laws
  • Natural monopoly — achieved through economies of scale
  • Government policies — regulation, public ownership, or laissez-faire
