Isoquant derived from Italian word

iso= equal quant= product

Geometric representation of production

funtion

Isoquant indicates various combinations

of two factors of production which give

the same level of output per unit of time.

Fixed inputs – constant in nature

ex: land, building, asset etc

Variable inputs – vary with the

environment

labour

iso-quant represents 2 variable inputs

capital(k) and labour (L)

Isoquant ISOQUANT

MARGINAL RATE OF TECHNICAL SUBSTITUTION

the rate at which a firm must

substitute one input for another in

order to keep production at a given

level

the rate at which capital can be

exchanged for 1 more (or less) unit of

labor

MPK = the marginal product of K

MPL = the marginal product of L

Q= MPK K + MPL L

Q= 0 along a given isosquant

MPK K + MPL L = 0

MRTS= K/ L
