Theme 3.5 Flashcards
What does the demand curve for labour show?
The demand curve for labour shows the quantity of labour that employers would wish to hire at each possible wage rate.
What is MRP (marginal revenue product)?
The extra revenue generated by an individual worker.
What is the demand for labour determined by?
The MRP. The higher the MRP, the higher the demand for workers. Due to diminishing marginal productivity, in the short run increasing the number of workers will initially increase MRP, but will then cause it to decrease.
What two factors cause the demand for labour to be downwards sloping?
1) In the long run, all factors of production are variable, and therefore high wage rates will encourage businesses to use machines rather than workers.
2) In the short run, firms have fixed levels of capital and so diminishing marginal productivity means adding extra workers gives a lower return, so to employ extra workers the wage rate will have to fall.
What is the equation for marginal revenue product?
Marginal output x price, or simply just the difference in total revenues.
How is the demand for labour derived from demand?
Firms hire workers in order to produce goods to meet their aim, usually of making a profit. Therefore, the demand for labour is derived demand as it is derived from demand for the product the labour produces. Businesses only want the worker for as long as people are willing and able to buy the product they produce.
What factors influence the demand for labour?
-Wage rates
-Demand for the product
-Prices of other factors of production
-Wages in other countries
-Technology
-Regulation
How does the wage rate influence demand for labour?
A wage is the price of labour and so has the same influence on demand for labour as price has on the demand for a product. As wage rates increase, demand for labour contracts since the MRP of labour must be higher for it to be worthwhile employing more people, so less people are employed.
How does the demand for the product influence demand for labour?
Since labour is a derived demand, if there is no demand for the product, there is no demand for the labour. Firms won’t employ people if the goods they make aren’t going to be sold and make a profit. An increase in demand for the product leads to an increase in demand for labour. This is linked to the concept of MRP: an increase in output or price of a good will increase demand for the labour that produces that good.
How does the price of other factors of production influence the demand for labour?
If machinery and equipment becomes cheap, people will switch machinery for labour and therefore the demand for labour will fall.
How do wages in other countries influence the demand for labour?
If wages are lower in other countries and therefore wages in the UK are relatively high, people will be employed in other countries as it represents a lower cost for businesses. This means that demand in the UK is low.
How does technology influence the demand for labour?
Improvements in computers and technology means that many jobs have been lost with the work being done by machines. This means that there is less demand for labour, but demand for labour in technological based industries is increasing. By 2040, about 47% of jobs could be lost to technology.
How does regulation influence the demand for labour?
As laws are passed some jobs disappear, such conductors, whilst other jobs are made. High regulation within the labour market is likely to discourage firms from hiring since it can be very costly and time-consuming so this will reduce demand for labour in these areas. France is a country that used to have high levels of labour regulation and this is something the new president, Emmanuel Macron, is trying to change.
How can the state of the economy influence demand for labour?
This is because this also impacts the demand for the product. When the economy is in a recession/slump, there will be low demand. Furthermore, businesses confidence relates to the expected state of the economy in the future, and workers may be laid off or at the least firms will employ less new workers as they’re worried about a lack of future growth.
What is the price elasticity of demand of labour?
This is the responsiveness of the quantity demanded of labour to the wage rate.
What factors affect the PED of labour?
● It is directly correlated to the price elasticity of demand for the product the labour produces. If the good is elastic, then a rise in wages and hence a rise in prices for consumers will have a large impact on the quantity the business sells. This will mean that the business will reduce the number of people it employs, in order to help it make a profit.
● It is affected by the proportion of wages to the total cost of production: if wages are a huge proportion of costs, then an increase in wages will increase costs massively and so there will be a large fall in demand for labour hence it will be elastic.
● If there are many substitutes, such as machinery and labour in other countries, then the demand will be elastic. This means high skilled jobs tend to be more inelastic than low skilled jobs as the labour cannot be easily replaced.
● Time also plays a role. In the long run, it is more elastic as machinery can be developed and jobs can be moved whilst in the short run firms have to employ workers and redundancy payments can be expensive.
What is the supply of labour?
The supply of labour curve shows the ability and willingness of people to make themselves available to work at different wage rates.
What factors influence the supply of labour?
-Wages
-Population and distribution of age
-Non-monetary benefits
-Education/training
-Trade unions/barriers to entry
-Wages and working conditions of other jobs
-Legislation
How do wages influence the supply of labour?
The supply of labour curve for an individual is a backward bending curve: an increase in wages will lead to an increase in hours worked at first but beyond a certain point, it will lead to a decrease in hours worked. However, we are concerned with the supply curve for a particularly occupation; this is more likely to be the typical upward sloping curve. Firms can increase the number of hours worked by its workforce in two ways: it can increase the number of hours by its existing labour force or it can recruit new workers. Therefore, although an increase in wage rates may not increase the number of hours worked by existing labour, it will increase the number of workers. This is because new workers may join from other industries or from being unemployed.
How do demographics influence the supply of labour?
A high population will mean there is a large supply of labour. The distribution of age is important as there needs to be many people of high working age to ensure there is lots of labour. Migration plays a role in determining the workforce, since many migrants are of working age and come to the UK to work.
How do non-monetary benefits influence the supply of labour?
Supply of labour will increase if there is high job satisfaction, for example in vocational jobs. Some jobs are attractive because they are close by or in an area with good social life, such as London, require little commuting or are near friends and family. Similarly, some jobs offer perks such as free private healthcare etc. which will increase supply. Factors such as holiday, hours of work, flexibility and opportunities for promotion also play a significant part.
How does education/training influence the supply of labour?
More educated workers means there is a higher supply of workers. This is particularly important for some industries which require qualifications. Occupations which require high levels of education may suffer from lower supply of labour compared to low skilled jobs.
How do trade unions and barriers to entry affect the supply of labour?
Trade unions may be able to restrict the supply of labour by introducing barriers to entry, for example you have to have a degree for teaching.
How do wages and conditions of other jobs influence the supply of labour?
If many jobs in a local area are considered to be unpleasant and offer low wages, then supply for alternatives will be higher.
How does legislation influence the supply of labour?
The government rules can affect supply of labour, for example school leaving age and the retirement age.
How does the level of government spending and tax affect the supply of labour?
High tax rates and high welfare benefits can reduce incentives and means there is a lower supply. This affects the entire workforce, and so therefore will have an impact on individual occupations.
What is the elasticity of supply of labour?
This is the responsiveness of supply to a change in wage rates.
What factors affect the price elasticity of supply of labour?
-Level of qualification or training needed
-The availability of labour in substitute markets
-Vocational nature of jobs (many teachers are teachers because they love teaching, not because of what the salary is)
-Time scale: in the long term elasticity rises.
-Level of unemployment- high unemployment means a more elastic supply as firms can increase the number of workers without a large wage increase.
Why is the supply of labour curve usually upwards sloping? (Substitute effect)
This is because of the trade off between income and leisure, and the rising opportunity cost of not working an extra hour as wages increase. Therefore, workers will usually feel more inclined to work more hours if the wage is higher, because the high wage outweighs the possible leisure benefits that hour could hold out of work. This causes the demand curve to be upwards sloping. This is known as the substitute effect.
