INSIGHT

Deficits Are Inflationary Only If Money Is Created

  • Deficits alone don't cause inflation; financing matters.
  • If deficits are underwritten by banks creating deposits (with Fed reserve support), new money enters the spending stream and raises prices.

Monopoly Critique Needs A Dynamic Comparison

  • Monopoly critique depends on what world you compare to; a lone innovator's 'monopoly' should be compared to zero output, not perfect competition.
  • Rothbard argues entrepreneurial discovery justifies temporary market power and breaking firms can reduce innovation incentives.

  • The 'excess capacity' paradox rests on smooth-curve geometry assumptions, not necessity.
  • Rothbard shows kinked average cost curves can yield monopolistically competitive firms producing at minimum average cost.
