  1. Chapter 24 Money and Inflation

  2. Money and Inflation: Evidence • Inflation is always and everywhere a monetary phenomenon • Whenever a country’s inflation rate is extremely high for a sustained period of time, its rate of money supply growth is also extremely high • Reduced-form evidence

  3. FIGURE 1 Money Supply and Price Level in the German Hyperinflation Source: Frank D. Graham, Exchange, Prices and Production in Hyperinflation: Germany, 1920–25 (Princeton, NJ: Princeton University Press, 1930), pp. 105–106.

  4. Views of Inflation • Money Growth • High money growth produces high inflation • Fiscal Policy • Persistent high inflation cannot be driven by fiscal policy alone • Supply Shocks • Supply-side phenomena cannot be the source of persistent high inflation • Conclusion: always a monetary phenomenon

  5. FIGURE 2 Response to a Continually Growing Money Supply

  6. FIGURE 3 Response to a One-Shot Permanent Increase in Government Expenditure

  7. FIGURE 4 Response to a Supply Shock

  8. Origins of Inflationary Monetary Policy • Cost-push inflation • Cannot occur without monetary authorities pursuing an accommodating policy • Demand-pull inflation • Budget deficits • Can be the source only if the deficit is persistent and is financed by creating money rather than by issuing bonds

  9. Origins of Inflationary Monetary Policy (cont’d) • Two underlying reasons • Adherence of policymakers to a high employment target • Presence of persistent government budget deficits

  16. The Discretionary/Nondiscretionary Policy Debate • Advocates of discretionary policy regard the self-correcting mechanism as slow • Policy lags slow activist policy • Data lag • Recognition lag • Legislative lag • Implementation lag • Effectiveness lag

  17. The Discretionary/Nondiscretionary Policy Debate (cont’d) • Advocates of nondiscretionary policy believe government should not get involved • Discretionary policy produces volatility in both the price level and output

  18. FIGURE 11 The Choice Between Discretionary and Nondiscretionary Policy

  19. Expectations and the Discretionary/Nondiscretionary Debate • If expectations about policy matter, discretionary policy with high employment targets may lead to inflation • Nondiscretionary policy may prevent inflation and discourage leftward shifts in short-run aggregate supply that lead to excessive unemployment • Must be credible • Constant-money-growth-rate rule
