Chapter 12 - Factor Markets: Labour Flashcards
Labour is a costly factor of production. The cost of labour is the largest cost factor in the economy. How can one ensure that higher salary demands do not have a negative effect?
Productivity must be increased
Which 2 forces is responsible for the backward-bending in the labour supply curve?
The substitution effect and the income effect.
What is the substitution effect in labour?
The higher the wage rate, the more hours people are prepared to work to get a higher income for goods and services. They are sacrificing leisure time. The higher wage rate therefore increases the opportunity cost of leisure - work is substituted for leisure.
What type of good is leisure seen as?
A normal good. Demand for normal goods increase as income increases.
What is the income effect?
Leisure is seen as a normal good. The demand for normal goods increase as income increase. Therefore as the worker’s income increase the demand for leisure will increase.
Who supplies labour?
Households
When will the market supply of labour for a particular type of labour change?
When any of the non-wage determinants of the supply of labour change. This will cause a shift in the market supply curve.
Give 4 possible reasons for the market supply of labour to change (shift)
- new workers enter the market (eg population increase)
- number of workers decrease ( eg due to HIV)
- wages in other occupations change (making them more or less attractive)
- non-monetary aspects change (eg job becomes less dangerous)
In deciding whether more workers should be employed, which factors do the firm compare?
The firm compare the Marginal Benefit derived from employing the worker with the Marginal Cost of employing the worker. As long as the Marginal Benefit exceeds the Marginal Cost more workers can be employed.
At what point must the firm stop employing more workers?
When Marginal Benefit is equal to Marginal Cost
When are participants of the labour market Wage Takers?
When the wage rate is determined by the demand for and supply of labour in the market. No individual participant can influence the wage rate.
Which 2 factors determine marginal benefit to a firm to employ additional units of labour?
Physical productivity of labour and the marginal revenue (in monetary means)
What is Marginal Revenue?
The additional revenue that a firm earns when it sells an additional unit of its product.
What is MPP in labour?
Marginal physical product of labour
What does MPP represent?
Indicates the physical value to the firm of employing an additional unit of labour?
How is Marginal Revenue Product calculated?
Physical value (MPP) multiplied by the Marginal Revenue (MR) MRP = MPP x MR
When is a firm perfectly competitive ?
When Marginal Revenue (MR) is equal to Price of the product (P)
What is the result of a firm being in Equilibrium ?
Profits are maximised
When is Equilibrium (max profits) achieved?
When MRP is equal to the wage rate
ie. Marginal Benefit = Marginal Cost
MRP = w (wage rate)
Demand for labour derives from …
Demand
In a perfectly competitive goods market MR = P
Therefore MRP = VMP
What is the relation of MR to P in Imperfect Competition?
Marginal Revenue will be lower than Price (since Prices have to be lowered to increase sales) This results in fewer employees being employed - Ceteris paribus
Give 6 possible reasons why market demand for labour can change. (Shift in curve)
1) number of firms change (employers)
2) price of product change
3) when productivity change (MPP)
4) new substitute for labour (machines)
5) change in price of a substitute factor of production (cheaper machines)
6) price of a complementary factor of production change (eg. Price of trucks decrease, buying more trucks means more drivers are needed)
On what does the magnitude of the changes in the wage rate and levels of employment depend on?
The elasticities of demand & supply
Is the labour market completely flexible or inflexible?
Flexible
