Money and Inflation: Money and Inflation: EvidenceEvidence
• 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

Origins of Origins of Inflationary Monetary PolicyInflationary 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

Budget Deficits and InflationBudget Deficits and Inflation
Government Budget Constraint
DEF = G – T = MB + BWhere: G = government spending
T = tax revenues MB = monetary base B = Bonds
• Deficit financed by bonds, no effect on MB and Ms
• Deficit not financed by bonds, MB and Ms

Budget Deficits and Money Budget Deficits and Money Creation in CanadaCreation in Canada
• Financing persistent deficits by selling bonds increases the supply of bonds, drives bond prices down and interest rates up
• If the Bank of Canada prevents higher interest rates by buying increasing amounts of bonds, the net result is open market operations
• This can increase the monetary base and the money supply, resulting in inflation

Budget Deficits and Money Budget Deficits and Money Creation in Canada Creation in Canada (Cont’d)(Cont’d)
• The Ricardian Equivalence contends (given government deficits) the public will increase savings in anticipation of higher future taxes
• Increased savings take the form of increased demand for bonds, matching the increased supply
• This leaves bond prices and interest rates unchanged and there is now need for the Bank of Canada to purchase bonds to keep interest rates from rising

Expectations and the Expectations and the Activist/Nonactivist DebateActivist/Nonactivist Debate
• If expectations about policy matter, then accommodating activist policy with high employment targets may lead to inflation
• Nonactivist 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
