Patinkin’s Integraton of the Monetary Theory and the Value Theory
rofessor Patinkin’s integration of value theory with monetary theory and with the theory of
employment is a highly impressive architectonic accomplishment, based on a single

the utility or safety yielding quality of the balances. This analytical device is
analogous to the deviation of the demand for the consumer goods from their utility.
The author first incorporates the demand for real balances (money balances deflated
for the price level) into the theory of consumer choice on the level of micro analysis. Thus,

The classical quantity theory of money maintains a dichotomy between the monetary
. It (classicist) assumes that money is a neutral (the classical
economists’ belief that changes in the money supply affect the general price level, but not
relative price. Relative price refers to any price expressed as a ratio of another price) and
having no influence on output, which is governed by real variables like labour, capital, and
technology. An increase in money supply increases absolute price level without affecting
relative prices, which are determined in the real sector. Patinkin has rejected the classical
dichotomy between the monetary sector and the real sector in his monumental work, “Money,
Interes, and Prices (1965)”. He argued that dichotomy between monetary sector and real

Don Patinkin (1954) challenged the classical dichotomy as being inconsistent, with
the introduction of the ‘real balance effect’ of changes in the nominal money supply.
According to Patinkin, an increase in the quantity of money first influences the
demand for the commodities and their relative prices through real balance effect and then the
absolute prices. Thus, Patinkin has attempted to integrate the monetary sector with the real
sector through the real balance effect. He postulated that the existence of a real balance effect
in real sectors integrates monetary and real sector.
The early classical writers postulated that money is inherently equivalent in value to
that quantity of real goods, which it can purchase. Therefore, in Walrasian terms, a monetary
expansion would increase prices by an equivalent amount, with no real effects on
employment on output and employment. Patinkin postulated that this inflation could not
come about without a corresponding disturbance in the goods market. As the supply of
money increases, the real stock of money balances exceeds and thus, the expenditure on good
rises, which establish the optimum balance. The rise in price level in the goods market will
continue until excess demand is satisfied, at the new equilibrium. He thus argued that the
classical dichotomy was inconsistent in that it did not allow for this adjustment in the goods
market

.
Don Patinkin’ real balance effect theory is based on the following assumptions:
1.
Money could not change the real magnitudes of economic variables. That is they
believe in neutrality of money;
2.
Expectations are unit elastic;
3.
All prices are flexible;
4.
No distribution effect exists; and
5.
There is no money illusion.
Patinkin believe that when price level changes, it affects the purchasing power of
the people; the real purchasing power of the people is real money balance, which people hold
in the form of cash balances, which ultimately affect the demand for goods and services. This
is the real balance effect.
If the price level increases, real money balances decreases (i.e., purchasing power
of money reduces). The reduction in real money balances will have two effects: (i) demand
for commodity will be reduced,(ii) wages and prices will fall (because demand for
commodities reduces). The initial decline in demand for commodities will generates
involuntary unemployment but this type of unemployment will not last for long time because
decline in demand for commodities will reduce wages and prices and reduction in prices and
wages will increase real money balances. This real money balance effect tends to increase
demand directly or indirectly through the interest rate. With sufficiently large fall in prices
and wages, full employment level of income and output will be restored.

Patinkin’s general equilibrium model considers three markets:

In summary, we can say that the Don Patinkin,s real balance effect theory: (i)
eliminates dichotomy between monetary sector and real sector; (ii) it validates the conclusion
of the quantity theory in equilibrium money is neutral and interest rate is independent of the
quantity of the money through the real balance effect; (iii) wage-price flexibility leads to full
employment in the long-run and that the Keynesian underemployment equilibrium is a
disequilibrium situation.
