economics hard MCQ

What does the 'Second Best Theorem' in welfare economics suggest?

  1. Free markets always lead to the most equitable distribution of wealth
  2. If one condition for Pareto optimality cannot be met, achieving the remaining conditions may not lead to a second-best optimum
  3. Government intervention is always superior to market mechanisms
  4. Monopolies are the second-best alternative to perfect competition

Answer: If one condition for Pareto optimality cannot be met, achieving the remaining conditions may not lead to a second-best optimum

The Theory of the Second Best demonstrates that in the presence of market failures (like a monopoly or an externality) that cannot be eliminated, trying to enforce the other conditions of perfect competition might actually decrease overall economic welfare. It suggests that targeted, seemingly 'distortionary' interventions might be required to counteract the existing distortion.
