Isocost
It is the locus of all different combinations of labourand capital that a firm can employ , given the totalcost and price of inputs

Marginal Rate of Technical substitution
It measures the reduction in one input, due to unitincrease in the other input that is just sufficient tomaintain the same level of output.
MRTS of capital for labour would be the amount oflabour that the firm would be willing to give up foradditional unit of capital.
MRTS of labour for capital is defined as the numberof units of capital which can be replaced by one unit
of labour, the level of output remaining unchanged. MRTS is equal to the ratio of the marginal physical
products of the two factors.

Special shapes of Isoquants
Linear Isoquants:- when there is perfectsubstitutability between two factors, isoquant
becomes linear
Right-angled Isoquants:- in case of complementaries

Elasticity of Technical substitution (betweenfactors)
MRTS of factor X for factor Y declines as factor X issubstituted for factor Y along an isoquant.
The relative change in the factor proportions( or
input ratios) as a consequence of the relative changein the marginal rate of technical substitution isknown as elasticity of substitution between factors.
It measures the percentage change in factor
proportions due to change in MRTS

Expansion Path
It is the line formed by joining the tangency pointsbetween various isocost lines and the correspondinghighest attainable isoquants.
