Episode notes
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.
Excess Capacity Is A Geometric Artifact
- 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.
