The input used in the production process to generate output
Lesson Objectives
Explain the rewards of the factors of production
Explain the concept of derived demand
Outline the marginal productivity theory
Apply the marginal productivity theory to the demand for land, capital and labour
Derived demand/Indirect demand
The demand for factors of production is described as a derived demand because the demand for a factor arises indirectly out of the need to fill consumers' demand for final goods or services
Marginal productivity theory
The demand for a factor of production input is based on the marginal product (additional output) of the factor and the price of the output produced by the factor
Assumptions of MPT/MRP theory
Perfect competition prevails in both product and factor market
The firm has at least one fixed factor of production and is considering how much of the variable factor to employ, hence firm operates in the short run and is subject to DMR
Law of diminishing marginal returns operates on the marginal productivity of labour
Labour is homogeneous
Full employment prevails
Limitations/Criticisms of MRP
Marginal physical product (MPP)
The additional output produced by the employment of an additional unit of a variable factor of production
Marginal revenue product (MRP)
The additional revenue generated by the employment of an additional unit of a variable factor of production
Calculating MPP, TR, MRP and plotting the MRP curve
1. Calculate MPP
2. Calculate TR
3. Calculate MRP
4. Plot the Marginal Revenue Product curve
The firm's demand for a factor of production is the MRP curve, as it shows how many units of the factor the firm is willing to employ at different price levels
The industry demand for a factor of production is determined by the horizontal summation of the individual MRP curves of all the firms in the industry
Perfectly competitive labour market
The labour market is like any other good in the market, except demand comes from firms instead of consumers. The price firms pay for labour is known as wages.
Assumptions of perfectly competitive labour market
Perfect competition prevails in both product and labour markets
Firms are price takers in the labour market
Workers are homogeneous and equally productive
Full employment prevails
Imperfectly competitive labour market
The monopsonist is the only employer in the industry and must raise the marginal wage to attract new workers if it wishes to employ more labour
In a monopsony, the monopsonist can pay workers less than their marginal revenue product, exploiting the workers
Supply of land
The supply of land of a given quantity at a given location is truly fixed in supply. The supply curve for land is perfectly inelastic.
Supply of capital
The supply of loanable funds comes from all those sources from which it can be borrowed, i.e. savings. The reward for this sacrifice is the rate of interest.
Factors affecting the supply of land
Land is fixed in supply
Natural limitations as constraints by topography, climate, access to water etc.
Extent of existing development
Zoning - Governments can control the development of communities through zoning restrictions
Factors affecting the supply of labour
Wage rates
Cost of living
Availability of alternative jobs
Trade union activity
Government policies
Backward bending supply curve of labour
As wage rates increase, the supply of labour may decrease as workers choose to work fewer hours and enjoy more leisure time
Factors affecting the supply of capital
Interest rates
Savings rates
Government policies
Confidence in the economy
Factors determining wages/salaries
Demand and supply of labour
Productivity of labour
Cost of living
Trade union activity
Government policies
Factors determining rent
Demand and supply of land
Productivity of land
Location
Government policies
Factors determining interest
Demand and supply of capital
Risk
Inflation
Government policies
Transfer earnings
The minimum amount of payment required to keep a factor of production employed in its current use
Economic rent
Payments made to any factor of production in excess (over and above) of the minimum payments required by the factor
Quasi rent
Economic rent that is only made possible due to the inelasticity of supply of a factor of production
Key terms in labour
Wage rate
Marginal revenue product
Marginal physical product
Average physical product
Transfer earnings
Economic rent
Quasi rent

4. Plot the Marginal Revenue Product curve
The MRP curve constitutes the firm's demand curve for a factor of production, since it shows how many units of factor of production a firm is willing to employ at different price levels
The industry demand for a factor of production is determined/obtained from the horizontal summation of the individual marginal revenue product curves of all the firms in the industry
