• QuantityTheoryof MoneywasfirstPropoundedin1588
byanItalianEconomist,Davanzati.
• John Locke wasclearlyformulatedtheTheory (attempted
to explaintheriseinpricesin Europe).
• TheorywaselaboratedbyDavid Hume in1752.

5. Irving Fisher’s Theory of
quantity of money

6. Irving Fisher (1867 – 1947)
“Purchasing Power of Money” - 1911
Quantityof Moneyincirculationincreases,thepricelevelalsoincreasesin direct
proportionandtheValueof moneydecreasesandvice versa.
Quantityof Moneyisreducedbyonehalf,thepricelevelwillalsobereducedby
onehalfandthevalueof moneywillbe twice.
M V+ MˈVˈ = P T
M- Money Supply
V - Velocityof Circulationof M(Numberof Transaction)
P - Price Level
Mˈ- Credit Money
Vˈ- Velocityof Circulationof Mˈ (Numberof Transaction)
T - Transactionperformed(Totalno.of G/S exchangedfor money)

Assumptions
P isinactiveelement(PricelevelwillnotinfluencetheMoneysupply)
V& Vˈ isassumedto be constant.
Theproportionof Mˈ to M remainsconstant..
T alsoremainsconstant.
Criticisms
Equation of Exchange does not explain the cyclical behaviour of Prices and
Production.
UnrealisticassumptionsuchasV,T etc.,areconstant.
PriceleveldependsuponmanyotherfactorslikeConsumptionhabits,CentralBank
Policy etc.,
