PolicSays Law and
Classical Monetary y
Says law is an idea frequently foundin Classical Economics
The idea rejects the possibility of ageneral overproduction or glut
Often stated as supply creates its
own demand Involves a rejection of Malthus
theory of gluts
Smith, Say, Ricardo, James Mill, and J.
S. Mill all supported Says Law

Bases of Says Law: I The first idea behind Says Law is
there cannot be too much saving
Saving becomes investmentexpenditure and is spent just asconsumption expenditure
Savings and investment expenditure
brought into equality via real interestrate adjustments

Bases of Says Law: II The second basis of Says Law has to
do with the demand for money
Generally the Classical view was thatpeople only held money balances toundertake transactions
Demand for money would bedetermined by the number oftransactions planned and the averageprice at which these transactions wereexpected to take place
People do not hold money as an asset
(as it pays no interest) So when people find their money
balance higher than they wish theyeither consume or save (invest)

Implications of Says Law
If no one runs their money balances
up or down then there is no hoardingor dishoarding of money
All income not consumed is saved
All saving is invested
All income is spent
Cannot be overproduction orunderconsumption (in general)
Full Employment Agg S = Agg D

Says Identity Classical writers sometimes say an
excess of supply is an impossibility(J. S. Mill)
Implies that Full Emp Agg S is always= Agg D
This is known as the identity versionof Says Law
A demand is a supply; a supplyis ademand
This does apply in a bartereconomybut does it apply in amonetary economy?

Says IdentityWould apply to a monetary
economy only if a monetary
economy behaved like a bartereconomy
Money only a veil and has no realeffects
If I sell something my moneybalance goes up and I then buysomething else to reduce mymoney balance
If I buy something my moneybalance falls so I then sellsomething to restore my moneybalance

Says Identity People cannot run up or run down
money balances
Dichotomizes the economy Real factors only determine
employment, output, income andrelative prices
Monetary factors have no realeffectsdetermine general price levelonly
Is this really what the Classical
economists thought?

Says Equality In many places Classical writers
suggest that various disturbancesmay cause temporary excess supply
J. S. Mill states commercial crisesmay lead to people wishing to runup money balancesexcessdemand for money or deficient
aggregate demand for goods In this case Says Law expresses an
equilibrium condition, notsomething that is always true or
true by definition This position is called Says
Equality

Says Equality If what the Classical Economists had in
mind was Says Equality we should find
discussions of disturbances andadjustment mechanisms
Monetary factors can affect the realeconomy but there are adjustmentprocesses back to an equilibrium at fullemployment
Direct mechanism
Indirect mechanism

Direct Mechanism People may wish to run up or down
their money holdings In a crisis people wish to hold
more money In this case people will try to
increase their money holdings byselling goods or selling off otherassets (stocks)
Md > Ms and full employmentAgg S > Agg D Price level falls until real money
balances increased and people no
longer wish to increase moneyholdings (real balance effect) Md = Ms and FE Agg S = Agg D

Direct Mechanism Or--Case of increasing money
supply Ms > Md, people find themselves
with more money than they wishto hold
Increase consumption orinvestment expenditures
Add D > FE Agg S Price level rises which increases
demand for money (real balanceeffect) until Md=Ms and FE Agg S= Agg D
Neutrality of money only asbetween equilibrium states.Money can be a disturbing cause.

Indirect Mechanism Some Classical writers also thought
monetary factors could have an effectthrough the i rate
Market i rate may not equal the real irate that would give S = I
If market i > real i, then S > I and FEAgg S > Agg D
If market i < real i, then I > S and AggD > FE Agg S
Adjustment via banks adjusting irates according to reserve position

Says Law--Conclusion Lack of clarity over what is always
true and what is true in equilibrium The many discussions of crises and
inflations makes it clear that theClassicals felt money could be a
significant disturbing cause Tendency to equilibrium at FE level
of output
Says equality rather than Says
identity
