Money and Inflation


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


German Hyperinflation 1921-1923


Views of Inflation

• The Continuous Money Growth Produced Inflation

Three kinds of an increase in money supply:

1) once-for-all increase in money supply

2) continuous and constant increase in money supply

3) continuous and accelerating increase in money supply

• One and for all increase in Price Level is not ‘(Permanent) Inflation’

• Only 2) and 3) can cause permanent inflation

• Inflation is always and everywhere a monetary phenomenon


Response to a Unexpected Continually Rising Money Supply

1->1’->2->2’->3->3’->4


Response to a Anticipated and Continually Rising Money Supply:

1->2->3->4

Can Fiscal Policy alone Produce Inflation?:

• Can Expansionary Fiscal Policy or Government Deficits lead to an increase in Price Level?

• Only when the deficits are financed by Money Creation or an Increase in Money Supply?

• That happens only when Bonds are sold to the Central Bank and the proceeds are spent on domestically produced goods.

• Thus a ‘permanent inflation’ is only possible when persistent deficits are continuously funded by money creation.



Budget Deficits and Inflation I

Government Budget Constraint

DEF = G – T = MB + BWhere: G = government spending

T = tax revenues MB = Bonds sold to the central bank = monetary base

*Just printing money for G is unconstitutional in most developed countries; At least on surface this takes the form of the Ministry of Finance selling the bonds to the Central Bank

B = Bonds sold to the general public• Deficit financed by B, no effect on MB and Ms

• Deficit not financed by B, MB and Ms

Hypothesis of Ricardian Equivalence

• This is the case where government expenditures are completely financed by bond sales to the general public(dG = dDeficits =d Bonds).

• The public are far-sighted and concerned about the welfare of the future generation; and behave responsibly by buying the bonds and bequeathing the bonds for the next generation (dBonds = d Savings)

• Nothing would happen to Money Supply (MS) or interest rate(i).



Can Fiscal Policy alone Produce Inflation?:(Only one time increase in Price Level is not

Inflation)


Can Supply-Side Phenomena alone Produce Inflation? No.


Origins of Inflationary Monetary Policy I

• Inflation occurs only when money supply keeps increasing (over and again):

• When does the continuous increase in money supply occur?1) Cost-push inflation

– Cannot occur without monetary authorities pursuing an accommodating policy

2)Demand-pull inflation3) Budget deficits

– Can be the source only if the deficit is persistent and is financed by creating money or selling bonds to the central bank.


Origins of Inflationary Monetary Policy II

• Two underlying reasons– Adherence of policymakers to a high employment

target

– Presence of persistent government budget deficits


High Employment Targets and Inflation


The Choice Between Activist andNon-Activist Policy


Demand-Pull Inflation

B = Bonds sold to the general public• Deficit financed by B, no effect on MB and Ms

• Deficit not financed by B, MB and Ms


Budget Deficits and Inflation II

Financing persistent budget deficit by money creation (monetizing debt – printing money) leads to sustained inflation

Government Deficit is inflationary only if it is:1. Persistent2. Financed by money creation(bonds sold to the central bank) rather than by bonds sold to the general public


Budget Deficits and Money Creationin Canada I

• 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 Creationin Canada II

• 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 no need for the Bank of Canada to purchase bonds to keep interest rates from rising

Discretionary/Nondiscretionary Policy Debate I

• Discretionary policy advocates view self-correcting mechanism as slow

• Relevant lags slow activist policy– Data lag– Recognition lag– Legislative lag– Implementation lag– Effectiveness lag


Discretionary/NondiscretionaryPolicy Debate II

• Nondiscretionary advocates believe government should not get involved– Activist accommodating policy produces volatility

in both the price level and output


Expectations and Discretionary/Nondiscretionary 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
