Q

How is a wage a derived demand?

A

The demand for a wage comes from the demand to consume goods and services

Q

In the short run for a firm, what will they experience in terms of demanding their labour?

A

At least one factor of production is fixed, meaning the law of diminishing returns will set in at one output point

Q

At point A in the short run demand for labour curve, what is happening and why?

A

Each additional worker is bringing in more revenue than the previous worker, their marginal revenue product is increasing. This happens because of specialisation, excess land and capital which they can fill

Q

At point B on the short run demand for labour curve, what happens?

A

The constraints of the fixed factors of production set in, law of diminishing marginal returns sets in and MRP falls

11
Q

If the wage (marginal cost of labour) is equal to the MRP, should they hire more workers?

A

No, because any additional worker when diminishing marginal returns sets in will lead to a fall in MRP up to the point where MCL > MRP meaning the firm will lose money

Q

If the wage (marginal cost of labour) is equal to the MRP, should they hire less workers?

A

No, because although marginal revenue product is falling, total revenue for the firm is still increasing so reducing the amount of workers will only lead to a fall in total revenue

Q

What does the demand for labour curve look like for a market?

A

Inverse relationship between wage and quantity of workers demanded. Just like the normal demand curve for a product

Q

Why, in the long run, is there an inverse relationship between wage and quantity?

A

Because at higher wage rates, because factors of production are not fixed, firms can substitute capital for labour

Q

What factors affect demand for labour (causing a shift)?

A
  1. final price of product labour is making
  2. change in demand for final product
  3. changes in labour productivity
  4. changes in the price of capital

16
Q

How will the final price of the product the labour is making shift the demand for labour curve?

A

If the final price of the product rises, the marginal revenue for the firm will rise, causing the MRP to rise further shifting the demand for labour curve to right. The opposite is true for a fall in the final price

17
Q

How will a change in demand for the final product shift the demand for labour curve?

A

If the demand for the end product increases, the demand for labour will increase because it is a derived demand.

18
Q

How will a change in labour productivity shift the demand for labour curve?

A

If productivity increases, marginal physical product will increase as workers can produce more in a certain period of time leading to an increase in the MRP

19
Q

How will a change in the price in capital shift the demand for labour curve?

A

In the long run, all factors of production are variable, so if the price of capital falls the demand for labour will fall as firms will want to switch to the more price effective machines e.c.t

20
Q

What is the elasticity of the demand for labour?

A

Measures the responsiveness of labour demanded given a change in the wage rate

21
Q

What are the 4 factors that affect the elasticity of demand for labour?

A
  1. substitutability of labour
  2. elasticity of the product
  3. cost of labour as a % of total costs
  4. time period
    SECT
22
Q

How does substitutability of capital labour affect the elasticity of demand for labour?

A

If there are many substitutes available in terms of capital, demand for labour will be elastic

23
Q

How does the elasticity of demand for the product affect the elasticity of demand for labour?

A

If the PED of final product in inelastic and wages go up, demand for labour won’t change all that much as producers can pass the extra cost (wage) onto the consumer with the inelastic PED

24
Q

How does the cost of labour as a % of total costs affect elasticity of demand labour?

A

The greater the costs of labour are to total costs, the more elastic the demand for labour would be

25
Q

How does the time period affect the elasticity of demand for labour?

A

In a short time period, firms will have an inelastic demand for labour as there isn’t time to look for alternatives
