Episode notes
Stable Prices Support Institutional Entrenchment
- A long stable price level (1815–1914) coincided with entrenched institutions and policy continuity.
- Stable money is a precondition for institutional development, not a sole cause.
Hyperinflation Shatters Middle-Class Faith
- German hyperinflation destroyed middle-class savings and undermined faith in the system.
- That loss of legitimacy was a key precondition for extremist politics in the 1930s.
'Inflation Kings' And Social Scapegoating
- After hyperinflation, anti-Semitic 'inflation kings' were blamed as profiteers in hard-hit areas.
- Such social scapegoating helped fuel radical politics even after prices stabilized.
