Economic Principle 13: Competition Increases Efficiency

• Definition of Allocative Efficiency:

  • Firms produce the correct amount of goods/services from society's viewpoint.

• Impact of Competition on Allocative Efficiency:

  • Increases the number of efficient trades.
  • Competitive markets achieve more trades compared to monopolistic markets.
  • Monopolies restrict trades, leading to allocative inefficiency.

• Example of Trades:

  • Trade 1: Buyer values product at 120, seller values it at 90. Good trade increases economic value by 30.
  • Trade 2: Buyer values at 100, seller at 90. Good trade increases value by 10.

• Monopolist Pricing:

  • Monopolist sets higher price (e.g., 120) to maximize producer surplus but may lead to fewer trades.
  • Higher pricing leads to deadweight loss - the lost value from beneficial trades that do not occur.

• Deadweight Loss:

  • Definition: Lost value from efficient trades that are not undertaken.

• Competitive Market Pricing:

  • Forces prices down to lowest levels (e.g., cost at 90).
  • Enables both trades to occur, increasing overall economic surplus (40 instead of 30 in monopoly).

• Reduced Bargaining Costs:

  • Competitive markets eliminate haggling, stimulating more trades.
  • Less time spent negotiating leads to higher market efficiency.

• Types of Efficiency:

  1. Allocative Efficiency: Correct allocation of resources leading to optimal trades.
  2. Productive Efficiency: Firms produce at lowest possible average cost, ensuring competitive viability.
  • Companies must invest in technology to minimize costs.
  1. Dynamic Efficiency: Encourages innovation due to competitive pressures, driving firms to improve and innovate.

• Conclusion:

  • Competition reduces prices, increases trade quantity, prevents deadweight loss, and fosters innovation ensuring overall market efficiency.
