The Demand for factors of production

Why factor pricing is important? -

1. Money - income determination - factor pricers are a major determinant of household income.

2. Cost Minimization - pf determines how much of each is employed as the ﬁrm tries to

minimize cost in order to max. proﬁt

3. Resources Allocation - FP allocate inputs among industries and ﬁrms.

4. Policy Issues

Marginal productivity Theory of Factor Demand

Derived Demand

-the demand for a factor is derived from the demand for the products that the factor helps to

produce. more demand for a product the higher the demand for factors that of into

manufacturing it.

Marginal Revenue Product (MRP) - its the ﬁrms demand schedule for labour.; how much each

successive unit of a factor adds to total revenue.

because resources demand is derived from product demand, the strength of the demand

for any doctor of production will depend on:

1. Productivity - Productivity is the merging product. of the factor (when adding an additional

unit of output, marginal product)

2. Price of the good it helps to produce (marginal revenue product:

3. [Change in total revenue] / [Unit change in factor quantity]

Marginal Factor Cost -

what each additional; unit of a factor adds to the ﬁrm’s total (factor)cost -

[change in total (factor) cost] / [unit change in factor quantity]

MRP = MFC :rule for employing factors

Determinants of Factor Demand: Shift of Curve

1. Changes in product demand - increase in demand for the product the factor helps

to produce, increaser the demand for a factor.

2. Changes in Productivity - increase in productivity of factor increases demand for it

i.e. demand for labor

(i) Quantities of other factors - more technical progress in capital used with

labour, the marginal productivity of labour increases.

(ii) Technological advance - MP increases, can also lead to loose of jobs

(iii) Quality of the variable factor - if the “quality of labour” increases,

productivity rises.

“Winner-take-all-market” - when a ﬁrm earns an enormous amount of money, while vast

majority of the ﬁrms are getting a little money.

Document Summary

The demand for a factor is derived from the demand for the products that the factor helps to produce. more demand for a product the higher the demand for factors that of into manufacturing it. Marginal revenue product (mrp) - its the rms demand schedule for labour. Marginal factor cost - what each additional; unit of a factor adds to the rm"s total (factor)cost - [change in total (factor) cost] / [unit change in factor quantity] Winner-take-all-market - when a rm earns an enormous amount of money, while vast majority of the rms are getting a little money. !2: changes in the prices of other factors - assume price of machinery falls, that happens to the demand for labour if the can be substitute. (i) substitute factors of production : Substitution effect - substitution of machinery for labour, therefore some labour displaced.
